    We develop an analytical framework of a multiproduct supply chain system composed of multiple suppliers, multiple distribution centers and multiple customers considering disruptions risk. Unlike traditional single sourcing strategy which is mostly discussed in supply chain literature, we apply multi-sourcing strategy in both procurement and distribution of commodities. The model thus developed determines the location of distribution centers from a set of potential location, shipment decisions from multiple suppliers to multiple distribution centers and shipment decisions from multiple distribution centers to multiple customers. Moreover, the model evaluates potential amount of products shortages in the event of disruptions. In our work, we consider disruptions at candidate locations for distribution centers and to the suppliers. The analytical framework is formulated as a mixed integer programming (MIP) model which minimizes the sum of investment cost, the transportation cost and the expected shortage cost. We consider several numerical instances to examine the benefit and practicability of the proposed model. Finally, we compare the results of the risk concern optimization framework to the basic optimization framework. From the results, it is expected that risk concern model would outperform the basic model in the case of disruptions.

    Research on coordinated inventory policy for perishable items between a manufacturer and a retailer has been extensively done. The majority studies however assumed that the stored item starts to deteriorate instantaneously once its production process completed. This may be suitable for representing the characteristic of certain perishable items such as alcohol or radioactive materials. In many cases, particularly for food products such as fruits, vegetables, meat and bakeries, over the shelf-life the quantity remains constant while the value does degrade once the product is approaching its expiration date. Despite this phenomenon, less research addresses this issue, particularly in a multi-echelon supply chain system. Therefore, this research deals with inventory policy for a manufacturer-retailer system considering value degradation for food products. A mathematical model representing the system is proposed. A shelf-life based pricing function is applied to represent the value degradation of the product. The objective function is to maximise the joint profit per unit time which is achieved by optimising the length of manufacturer’s production cycle (T) and the ordering frequency of finished goods (n) over the production cycle. The numerical test for the established model demonstrates that the model outperforms the existing model in terms of its potential capability of returning a significant profit improvement.

    This paper considers a supply chain system consisting of a manufacturer with her authorized retailers, an unauthorized intermediary and the regional government. Aim at the problem of the manufacturer’s price decision and service strategy in two markets under gray market, the demand function influenced by the consumer acceptance of gray goods and the manufacturer and the unauthorized intermediary’s profit model are established. By analyzing and discussing the effects of government supervision on manufacturer’s pricing decision and service strategy, this paper proposes the manufacturer’s optimal price and service strategy. The results show that if the government increases supervision the manufacturer will benefit while products demand and profits of the unauthorized intermediary will decrease. Thus, the government will achieve the target of combating gray market transaction. Besides, the manufacturer’s service level when the government does not provide any protection against the gray market is as same as the level when the government provides complete protection. The service level will be higher when the government provides incomplete protection. Furthermore the results are examined by numerical examples.

    Abstract Full PDF Cite DOI: 10.31387/oscm0200139
    The paper outlines the current concern of relocation in automotive industry in order to adapt to market conditions by shifting production towards emerging countries. Car manufacturers strive to reduce their operational costs to compensate weak sales in an attempt to overcome the slow market revival and remain globally competitive. The paper focuses on the Dacia-Renault low-cost car policy and uses the case research method to describe differences in consumer behaviour on the French, Romanian and Moroccan car markets. Relevant data and indicators for automotive industry from these 3 countries are analysed and compared by using linear interpolation providing an aggregate indicator with an overview on market dynamics and perspectives. Preliminary results show that drivers of relocation are mainly related to market opportunity, workforce costs and infrastructure. Macroeconomic indicators, acquiring needed skills by local workforce and a good management capacity seem to be more delicate issues. Moreover authorities from emerging countries provide fiscal advantages for car manufacturers willing to relocate their activity or build a new factory as they are a source of wellbeing for its population and economic growth for the country. The research conducts an analysis of advantages and disadvantages of relocation and provides recommendations to improve competitiveness and assure sustainable development of both car manufacturing companies and their supply chain.

    City logistics involves movement of city goods in urban areas respecting the municipal and administrative guidelines. The key goals of city logistics planning are maximizing vehicle movement and utilization, while minimising vehicle emissions and traffic congestion. Collaboration is vital to managing city logistics operations efficiently. Collaboration can take place in the form of goods consolidation, sharing of resources, information sharing, and so on. Two categories of models are proposed to evaluate these collaboration strategies. At the macro level, we present the collaboration matrix model; and at the micro level, we present the operational level model. The macro-level model focuses on the strategic decision making process necessary for stakeholders’ collaboration given the socio-cultural characteristics, economic, and environmental constraint factors, while the micro-level model applies the collaboration decision-making criteria derived from the macro-level analytic result to improve the activities of the city logistics operators. Results of the computational testing of our methodology on vehicle selection, goods to vehicle assignment, goods distribution and environmental impact assessment are discussed, showing that the collaboration strategies of stakeholders, if optimized, can improve city logistics operations. The proposed work is novel and has strong practical applicability for logistics planners and decision makers in planning right collaboration strategies for sustainable city logistics operations.

    The paper outlines current challenges in Romanian food industry, its potential to overcome them and be competitive on both the national and international market using a key performance indicator (KPI) methodology. Although it has the capacity to assure internal consumption and competition on the market is high the Romanian food sector is struggling to meet internal demand, imports heavily exceed exports while food consumption is decreasing. The retail sector is an important part of the supply chain, but the harsh competition among the different stores has made them pass the risks only towards the upstream links which is straining food processors and producers and threatening the sustainable development of the food supply chain. High taxation, unfair competition and delayed payments towards food processors add extra pressure on the weaker links of the chain. Moreover authorities are inefficient in assuring duly market conditions whereas scandals further degrade industry image and cause important losses. The lack of synergic efforts within the industry and the scarce collaboration efforts between business partners affect individual company performance and thus global industry competitiveness. The research provides solutions that address its structural issues and develops performance indicators to improve the efficiency of companies in order to assure their sustainable development within the supply chain and become more competitive on the global food.
