    Long-distance truckers are the lifeblood of complex supply chain networks. Thus, it is important to analyze ways to enhance the efficiency and effectiveness of these professionals. In particular, what factors contribute to their job satisfaction, quality of life, and overall success? These questions are partially answered in this study using the framework of appreciative inquiry to construct a comprehensive sketch of the day-to-day lives of long-distance truckers. While other aspects of the supply chain have been studied extensively, relatively less research has been directed toward understanding the nuances of the trucking way of life. The current paper offers some partial solutions, research directions, and managerial guidance.

  3. To Evaluate Cost Savings in a Supply Chain : Two Examples from Ericsson in the Telecom Industry

    Abstract Full PDF Cite DOI: 10.31387/oscm0150094
    An accurate cost analysis is necessary to evaluate changes in a supply chain; this article shows how a rather simple framework can be used when evaluating changes in a supply chain. The framework is built on a Supply Chain Cost (SCC) model and customer service measurements, delivery precision and lead-time. Both suggested changes in a supply chain and already executed changes can be evaluated by the framework. Two different examples from the company Ericsson are presented to illustrate the framework, which is a 5 step analysis model. The existing, or pre-existing, supply chain is analysed, described and defined. The SCC and performance measures are mea-sured and/or estimated. Improvements are designed and defined. The same measures as before are measured again. The measures from before and after the change of the supply chain are evaluated to decide if the changes are improvements or not. Cutting costs in one area of the supply chain can be a mistake if not the total supply chain is considered and the total SCC. Considering both the SCC part and customer service measures present a wider understanding of the change. It is shown that SCC can be used as a tool to identify cost savings and evaluate if a change project will, or has, resulted in the cost savings the project aims for. Rough standard costs measures should be avoided instead actual costs should be used as much as possible. The used framework hopefully stimulate to similar analyses in other companies with other supply chains.

    Stock prepositioning is one of the most important issues in preparedness stage of emergency logistics response. In a previous research, a stock prepositioning model to support an emergency disaster relief response in the event of earthquake has been proposed. Since the results contained zero proportion of some type of item, which is not allowed in a real system, an improvement of the model is needed. Hence, in this paper we focus on how to prevent the result of zero proportion of a single item type stored in distribution centers, which is the proportion of relief demand satisfied of disaster areas. We propose a new model by adding new variable of proportion of unsatisfied relief demand. Thus, we apply this model to a real case with 33 disaster areas and 16 distribution centers in Indonesia. Finally, the sensitivity analysis is performed to show the effect of different upper bound of the proportion of unsatisfied relief demand.

    In the present paper, a multi-item inventory problem with the capacity to replenish carriers is considered. In the present study, we propose a model that considers truck capacity, truck cost, and receiving inspection cost with inventories and shortages in inventory management simultaneously. A number of studies have examined the minimum total cost while considering the ordering cost as fixed and not considering the carrier capacity or receiving inspection cost. However, we consider the stepwise ordering cost, which changes in a stepwise manner according to the ordered quantity and the capacity of the carrier. In addition, we consider a receiving inspection cost that is defined not only by ordered quantity but also by ordered item variety. The problem considered herein was formulated as a mathematical programming problem in a finite planning period, and valid inequalities were considered. We could consider individual objective functions for ordering, holding, lost sales, and receiving inspection cost together. We can observe that the receiving inspection cost could be reduced by aggregating the order quantity.
