  1. Information Technology Outsourcing: Influence of Supplier Firm Size and Reputation on Buyers’ A Priori Perceptions of Opportunism and Uncertainty
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0390242
    Growth in outsourcing has led to a renewed focus on vendor and/or business partner evaluation and selection criteria as inept selection can have an adverse impact on core organizational outcomes such as revenues and profitability. Outsourcing activities include use of a third party to perform a variety of business functions such as contract manufacturing, sales, distribution, public relations, and information technology (IT) management. While transaction cost analysis (TCA) researchers have extensively studied outsourcing arrangements, they have not examined how vendor firm characteristics affect buyers’ a priori or pre-contract perceptions of opportunism and uncertainty during the vendor evaluation phase. Similarly, while the procurement research stream has identified and explained a range of supplier characteristics and their effect on buyer’s vendor selection processes, it lacks integration with TCA. This paper purports to advance both TCA and vendor selection research streams by studying the influence of supplier firm size and reputation on buyers’ pre-contract perceptions of opportunism and uncertainty. Higher opportunism and technological uncertainty perceptions in a pre-contract stage can prevent a vendor or channel partner from winning business. Support is found for a relationship between vendor firm reputation and buyers’ a priori perceptions of opportunism and uncertainty. Results further show that stronger reputation can mitigate the perception of opportunism, larger firm size, on the contrary, raises the degree of perceived opportunism. Results also support a relationship between opportunism and technological uncertainty.

  2. Relationships Between Green Supply Chain Drivers, Triple Bottom Line Sustainability and Operational Performance: An Empirical Investigation in The UK Manufacturing Supply Chain
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0390243
    Sustainability has assumed salience over the past years, thereby becoming a corporate mantra as well as a promising research area. Most sustainability studies have focused on environment friendly operations contributing to the concept. However, sustainability extends beyond environmental performance to also encompass economic and social performance. All the three factors combine to form the ‘Triple bottom line (TBL) performance’. This paper is an empirical investigation of the effect of green supply chain (GSC) drivers on the TBL performance and the influence of TBL performance on operational performance of manufacturing companies in United Kingdom (UK). Structural equation modelling (SEM) was used to reveal that GSC drivers like supplier and customer pressure and environmental purchasing positively influenced social and economic performance respectively, whereas eco-design and production influenced all the three parameters of TBL performance. It was interesting to find that social and economic performance, but not environmental performance, had a significant positive influence on firm’s operational performance.

  3. Fixed Shipping Cost Allocation for Just-in-Time (JIT) Lot-Splitting
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0390244
    This paper studies benefits of just-in-time (JIT) lot-splitting and multiple shipments for an order placed by the retailer in a two-stage supply chain. In a typical order placement and delivery setting between the buyer and the vendor, the treatment of the shipping cost is not clear and is contingent on negotiations between the parties involved. The outcome of such settlement often results in suboptimal practices in the supply chain. This paper investigates how the optimal and incentive aligned allocation of the fixed shipping cost from the manufacturer to the retailer can be obtained with the lot-splitting policy. Numerical results indicate that both the lot-splitting policy parameter and the fixed cost structures (e.g., fixed shipping to ordering cost ratio) command significant impact on the shipment frequency and the supply chain cost. The paper further proposes an approach to identify settings beneficial for the system.

  4. Understanding the Impacts of Length of the Contract and Fleet Size on Spare Parts Level and Reliability Investments in Performance-based Contracting
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0390245
    This essay investigates the impacts of contract features such as contract length and fleet size on reliability investment, spare parts, supplier’s profit, and the annual cost of the system in performance-based contracting (PBC). The impact of each contract feature analyzed using the multi-objective genetic algorithm in a mathematical model. We found that failure rates of the systems and the annual unit cost for the buyer exponentially decrease when the fleet size or contract length becomes larger. Also, an annual profit of suppliers grows substantially with an increase in fleet size and length of contracts. Additionally, we explored that these features have little impact on spare parts in PBC. Findings of this study advance understanding of the impact of fleet size and the length of contracts on decisions made by suppliers for the reliability and inventory investments in PBC. Furthermore, practitioners will benefit from the results to build effective and efficient PBC.

  5. Supply Chain Finance for SMEs - Case in Danang City
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0390246
    Recently, the number of Vietnamese small and medium enterprises (SMEs) is rapidly growing. Since most of them are run under owner’s capital, they easily face cash constraint situation during their operational life cycle. Hence, the demand for Vietnamese SMEs to optimize their liquidity has been increasing and becoming a top concern. Previous studies in the supply chain field focus much on the physical flow of products/services and informational flow. Meanwhile, the financial aspect as well as its sustainability in the supply chain has been received more attention after the financial crisis of 2008. This even gets more crucial when the uncertainties in the global economy and financial markets increase pressure on businesses’ cash as well as their supply chains (SC). Considering the role of this concept and its potential, this study tries to explore and examine the level of understanding about the monetary supply chain of SMEs based in Danang city and how they can access financial sources for more stability and sustainable business. The truth is, many SMEs face existing problems to access financial sources like banks as well as establishing a long-lasting SC. Without a doubt the fund-raising information infrastructure in Danang city is not well developed, and local businesses still depend on financial sources from banks. Also, the connection between buyers and suppliers is still weak as they do not invest much in the infrastructure or production line to create a common ground with the business’s product characteristics. In addition to that, this paper suggests some implications for the development of the local SMEs in general and their supply chains in particular.

  6. Product Variety, Supply Chain Complexity and the Needs for Information Technology: A Framework Based on Literature Review
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0390247
    Recently, many companies are competing against each other to be the first to offer new product in the market, even when offering new products brings additional challenges for their operations. At the same time, information technology is chosen as the most effective solution to help company facing supply chain problems that arise due to increasing flow of materials and information in the supply chain. However, many companies still do not fully considered the importance of aligning the needs of information technology with the supply chain and business conditions. This paper conduct a structured literature review on the influence of product variety, supply chain complexity, and the needs level of information technology. Based on the literature review a conceptual framework is developed that highlight three propositions: the potential relations between product variety and supply chain complexity, supply chain complexity and information technology, and the importance of aligning the implementation of information technology with the company’s business condition. Finally, the main propositions from this study is that there are potential connections among product variety, supply chain complexity, business condition and information technology.

  7. Offshoring Decisions: A Comprehensive and Conceptual Framework
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0380236
    The paper presents complexities involved in offshoring decisions and provides a comprehensive framework for making a reliable decision for offshoring. There is a need for a holistic approach to offshoring decisions. The paper identifies various drivers, categorizes them as revenue or cost drivers, and analyzes their impact on the offshoring outcomes. The framework rationalizes the extremes of unprecedented successes and unexpected failures among organizations engaged in offshore outsourcing. The proposed framework is expected to improve the quality of offshoring decisions. The proposed framework approaches offshore outsourcing decisions at a strategic level and will improve organizations’ performance on the triple bottom line.

  8. Supply Chain Incentive Alignment: The Gap between Perceived Importance and Actual Practice
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0380237
    Incentive alignment is discussed as one of the key factors for successful implementation of supply chain management. However, there is a lack of empirical research regarding implementation as well as evaluation of the effects of alignment mechanisms in practice. The purpose of this study is therefore to explore and describe the current practice and to identify gaps of Supply chain incentive alignment. The study is an explorative and descriptive survey study based on forty-eight responses from members, supply chain officers, of the Swedish Supply chain panel. The theoretical lenses are based on literature discussing incentive alignment in supply chains, e.g. principal-agency theory and supply chain contracting, but also on literature discussing internal process based management and rewards for goal congruence. The study shows a clear gap between perceived importance and realized practice of both external (inter-organizational) and internal (cross-functional) incentive alignment. Very few of the existing sophisticated coordinating mechanisms proposed in theory were used to any significant extent. In fact, the internal incentive structures seem to counter act, and not support, supply chain orientation. This finding relates not only to non-logistics departments but also to functions in “the logistics family”. The major challenge, both externally and internally, is to be able to define incentives that drives behavior in the right direction. The study clearly shows gaps between practitioners’ intent and current practice, and it provides a broad range of more sophisticated and coordinating mechanisms than the ones mainly used today.

  9. An Exploration of the Measurement of Relational Capital in Supply Chains
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0380238
    The aim of the paper is to identify and systemise dimensions and measures that can be used to evaluate buyer-supplier relational capital (RC). The authors used a literature review methodology composed of the following phases: question formulation, keyword search in databases, screening and analysis of articles. As a result, 44 articles were selected and finally analysed in detail. It was found that several theories can help to explain how buyer-supplier relationships contribute to a company’s value and competitive advantage. Furthermore, RC as an element of social capital deserves more investigation in a supply chain management context. Accordingly, to date there has been no relevant in-depth studies exploring the measurement of relational capital in supply chains. On the base of the review of research articles published between 2004 and 2018, the list of items used by researchers to measure the relational capital was explored. Then, authors proposed a construct for relational capital consisting of 5 items such as: trust, close interaction, respect, reciprocity and commitment, that were shortly discussed. Taking them all into account, an authorial definition of supply chain relational capital was proposed. Although, the final results contribute to the study of RC measurement within buyer-supplier relationships in supply chains, the analysis still has some shortcomings that need to be addressed in further literature studies and empirical research.

  10. Proposing a Framework for Developing Supply Chains of Medical Devices
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0380239
    To help develop supply chains for a medical device, this study proposed a framework based on literature review and the unique characteristics of medical devices. The framework first evaluates the structure of the medical device, the suppliers of raw materials or components, and the emerging technologies and manufacturing processes to be used to build the device. It then assesses the quality regulations and standards for the device and the manufacturing processes, the location of the suppliers, and the operation and maintenance of the device along the supply chain. This framework was applied to a case where supply chains were developed through Porter’s cluster mapping technique for two medical devices: an ultrasound machine and a prosthetic ankle. The preliminary results suggested that the features of the medical devices influenced the choice of their supply chains. In particular, a research-oriented device with customized components should have a localized supply chain (e.g., within Washington State in this case) while the consumer-oriented device with standardized components could have a national or even a global supply chain. Future research directions are suggested.

  11. Application of Queuing Theory to Optimize Waiting-Time in Hospital Operations
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0380240
    Waiting time is inherent to the healthcare service sector in India and a major challenge faced by almost every big hospital is queuing. Long waiting time can be a reflection of inefficiency in hospital operations. The out-patient department (OPD) has the biggest queue as compared to other departments in hospital operations. This study comprises of in-depth analysis of OPD from different dimensions. Like in many big hospitals across India, the OPD of Fortis Escorts Hospital in Jaipur, India is managed using experience and rule of thumb rather than strategic research-based techniques such as queuing theory. The Fortis Escorts Hospital in Jaipur receives a large number of patients each day which results in longer waiting time for patients due to long queues. To address this challenge, a SWOT analysis was conducted for the OPD of Fortis Escorts Hospital Jaipur (FEHJ) which resulted into dissecting the queuing problem and coming out with solutions knowing where the hospital operations can excel and where there is a scope of improvement to make the working and processes better. Additionally, after examining the problem analytically and applying queuing theory, measures were suggested to improve the delay points and make the OPD more efficient in order to gain a high patient satisfaction rating.

  12. Achieving Market Orientation Through Cross-Functional Integration
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0380241
    The purpose of this study is to understand how cross-functional integration contributes to the market orientation of a company that strives to increase market responsiveness. A case study in the Brazilian beverages industry was conducted and empirical data was collected through fourteen in-depth interviews from various functions within the company. The findings indicate that cross-functional integration enables the company to achieve market orientation through two main processes: product launch and customer complaints. Cross-functional integration enables a company to disseminate knowledge about organizational dynamics at both departmental and individual levels, to generate interdependency, to improve the awareness about the internal needs, and to improve the internal knowledge about the customer. This study shows that practitioners need to establish cross-functional integration, as it contributes to the market orientation of a company. Internal knowledge enables practitioners to create value through products and services, while still preserving the corporate image. It also shows that cross-functional teams and meetings are necessary to achieve market orientation in a company.

  13. Analysis of Multi-objective Decision Problems in Humanitarian Supply Chains
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0370223
    In humanitarian supply chains, there is a need to consider how to distribute the limited relief supplies that have not been prepared sufficiently to each shelter. Different from commercial supply chains that prioritize cost reduction, in humanitarian supply chains, it is important to consider not only reducing the distribution cost but also how to deliver goods quickly to satisfy the demands of shelters. Three metrics have been proposed for humanitarian supply chains: efficiency, equity, and efficacy. The objective of this paper is to define the metric of efficacy to minimize distribution time to each shelter considering the relief goods arrival. Under the situation after the disaster, to supply relief goods agilely and fairly, it is necessary to take account the weight of each metric adequately. We formulate a multi-objective mathematical model by the multiple metrics and carry out the optimization by using the model. The results show that the proposed multi-objective model is very promising in dealing with complicated humanitarian supply chains. Additionally, we show the deviation between the result of each metric and the multi-objective evaluation.

  14. A Shopping-path Length Estimation Using Markov-chain-based Shopper Dynamics Model
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0370224
    We propose a framework of estimating shopping-path length, in which the floor is represented by the graph G(V,E) with a vertex set V and an arc set E and the shopping-path length is measured by the number of zones (vertices) shoppers visit. We used the Markov-chain to model the dynamics of distribution of shoppers on the vertecies in the graph. We derive the (discrete) probability distribution of shopping path length using the transition matrix in the Markov-chain, and derive the expected path length. We proposed the index called the improvement importance index to quantify how local changes in the transition probability affect the entire shopping path length. We have tested our framework to the test data from an industrial application and the estimated path-length is compared to the actual one. We have a result that the error of estimation is 0.2%.

    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0370225
    This study investigates the effects of critical operational and strategical decisions in order-picking warehouses on order pickers’ tour lengths. For this study, one of the most-commonly applied layouts in practice, called two-block layout with a central cross aisle, was considered. A full factorial experimental design and multiple-comparisons (Bonferroni t-tests) were applied to statistically determine the significance of various levels of storage policies, pick-list sizes, warehouse shape ratios, warehouse sizes and their all interactions on average tour length. The analysis showed that deeper storage areas were superior to wider areas in small- and medium-sized warehouses. Warehouse designs with a 1:1 width-to-depth shape ratio offered the most robust layouts. Within-storage aisle policy significantly reduced order-picking tour length and generally outperformed other storage policies.

  16. A Multi Echelon Location-Inventory Model with Lateral Transshipment
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0370226
    In this research, a supply chain system consisting producer, distribution centers and retailers is modeled by considering lateral transshipment between distribution centers and also using echelon-based inventory system instead of independent inventory system. The model is developed in the form of mixed integer non-linear programming (MINLP) to minimize the total location, transportation, and inventory costs of the system. The model was solved using conic programming approach and validity was examined by comparing the developed model with the basic model (i.e. the model without the contributions) in several instances with different sizes of distributors and retailers. The results represent superiority of the developed model in computational time and objective value especially in medium and large-scale problems.

  17. Modelling Facility Location Problems in Emerging Markets: The Case of The Public Healthcare Sector in Morocco
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0370227
    Locating facilities in an emerging market involves specific characteristics that are different from developed countries. The differences between these two settings suggest that facility location modelling can present substantially different challenges when applied to an emerging market as opposed to a developed country. In this study, we develop a variant of the set covering model that explicitly takes specific characteristics into consideration. The model has been constructed and validated based on a real-life case study concerning the Moroccan Ministry of Health which is currently considering the redesign of its supply chain of pharmaceutical products. Amongst the findings, this paper shows that road infrastructure and demand dispersion affect the strategic decision of facility locations.

  18. The Influence of Shopping Path Length on Sales Growth and Its Variance
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0370228
    We study the influence of shopping path length on the number of items purchased. It is a well known fact in in-store shopper marketing that the longer the travel distance, the more items purchased. We analyze a shopping path data of 556 shoppers collected at a retail store in an urban are in Tokyo, Japan. We observed the fact the longer the travel distance, the greater the variance of the number of items purchased as well as its average. To explain this fact, we proposed a probability model of sequential purchase decisions using the Bernoulli process. We can estimate the number of items purchased as the binomial distribution given the shopping path. In the case study, we show how this assumption can be justified by the data from a real store.

  19. Supply Chain Risk Assessment: a fuzzy AHP approach
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0360217
    Managing supply chain risk is a big challenge for any organization. The purpose of the paper is to provide a methodology for assessing supply chain risk using the Fuzzy based Analytic Hierarchy Process (Fuzzy AHP). This study presents a comprehensive study to identify the Risk Factors (RFs) in supply chain and evaluate them. In this paper, sixteen risk factors were identified based on extensive literature survey. To limit the scope of the work, focus was on transaction and infrastructural risk and avoiding the demand risk. The RFs are formulated as hierarchy structure and Fuzzy AHP as a Multi Attribute Decision Making (MADM) tool applied to judge the viable candidates. A revised risk matrix with a continuous scale was proposed to assess the RFs classes. The result classifies the RFs in different categories (Extreme, High, Medium and Low). Based on this result, some management implications and suggestions are proposed. The revised risk matrix with continuous scale for risk assessment in supply chain is a novel approach.

  20. Supply Chain Integration, Learning, and Agility: Effects on Performance
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0360218
    This study examines the interrelationships among supply chain integration, learning, agility and organizational performance. Survey data were collected from 257 publicly-owned companies in Pakistan, and the hypothesized framework was tested using a structural equation model. It was found that supply chain integration had a significant impact on external and internal learning. Additionally, supply chain integration was found to have an insignificant impact on firm performance and supply chain agility. Finally, internal learning was found to have an insignificant impact on supply chain agility, but a significant direct impact on firm performance, while external learning had an insignificant impact on firm performance both directly and indirectly.

  21. Shelf-space Allocation Model with Demand Learning
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0360219
    In this paper, we studied the shelf-space allocation problem (SSAP). It is quite common recently to implement product design during a selling season and drastically change assortment decisions based on shelf-space allocation in response to up-to-date demand observations. While there are many literatures related to SSAP, However, existing literature assume that the demand is stationary. In this paper, we propose a dynamical framework to make shelf-space display decisions, in which space elasticity and potential demand are sequentially estimated using the latest data containing display space and sales for each product.

  22. Analysis of the Job Preferences for Undergraduate Supply Chain Students
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0360220
    The development of an effective recruitment strategy that attracts and secures entry-level logistics talent is essential to maintain corporate performance. To accomplish this, firms need to understand the attribute importance as well as the preferences of job applicants so that information can be used to develop more attractive job offers. To better understand job choice, choice based conjoint analysis was used. Key variables and their corresponding levels of interest in job choice were determined and presented to job seekers. Results of the current study indicate that for university undergraduate supply chain students, the three most important attributes used to evaluate entry level job positions are starting salary, fit with company culture and proximity of the worksite to friends and family. The results also show a preference for worksites located in the suburbs, in an office setting and for manufacturing firms. Below average preference was expressed for worksites in rural areas, those with lots of travel and firms in the retail and wholesale sectors. Implications for firms, educators and students are discussed.

  23. Inventory Control Policies for Substitutable Deteriorating Items Under Quadratic Demand
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0360221
    In today’s busy life, no one has sufficient time to buy or bargain any type of products. It is common in such cases that customers, who are looking for purchasing a certain product, will be willing to substitute with a comparable product when facing a stock-out, rather than visiting a different store to bargain the original product. In this article, we study an inventory control problem in which demand is fulfilled by using two similar substitutable items. Retailer fulfilled demand of one product by other substitutable product when stock-out of the one of them. We consider inventory levels of both of the items and time dependent demand. The orders for both products are placed at the same time. Our objective is to maximize joint profit for two substitutable deteriorating items with respect to cycle time and a time at which one product is stock-out.The numerical analysis is carried out based on the analytical results. The critical inventory parameters are computed for the decision maker.

  24. Supply Chain Integration: Does Organizational Culture Matter?
    Abstract Full PDF Cite DOI: http://doi.org/10.31387/oscm0360222
    The purpose of this quantitative correlational study was to identify relationships between organizational culture types, supply chain integration, and firm performance. The study process included obtaining data from 201 supply chain professionals and procurement specialists working in various companies throughout the United States. Supply chain integration data and firm performance derived from results obtained from participants completing a 5-point Likert-type scale survey. The Organizational Culture Assessment Instrument was used to determine organizational culture types. Results indicated a significant correlation between supply chain integration and firm performance. All three integration variables, customer, supplier, and internal were significantly and positively correlated with total integration and firm performance. Results also indicated that supply chain integration increased when organizational flexibility was present. Unexpectedly, both clan and adhocracy cultures were significantly correlated to supply chain integration and firm performance. The results from this study added to literature and provided supply chain managers practical knowledge of the significant influence organizational culture can have on supply chain integration performance. Results of this study substantiate that a flexible organizational structure, as shown in the clan and adhocracy cultures, increases supply chain integration and firm performance. As competitive forces intensify, the need for firms to develop a flexible organizational structure to leverage supply chain integration practices will increase. The results of this research could provide organizational leaders more insights into increasing supply chain integration efforts and improved firm performance through flexible culture alignment.
