An evolutionary approach for multi-objective optimization of the integrated location–inventory distribution network problem in vendor-managed inventory

Vendor-managed inventory (VMI) is one of the emerging solutions for improving the supply chain efficiency. It gives the supplier the responsibility to monitor and decide the inventory replenishments of their customers. In this paper, an integrated location–inventory distribution network problem which integrates the effects of facility location, distribution, and inventory issues is formulated under the VMI setup. We presented a Multi-Objective Location–Inventory Problem (MOLIP) model and investigated the possibility of a multi-objective evolutionary algorithm based on the Non-dominated Sorting Genetic Algorithm (NSGA2) for solving MOLIP. To assess the performance of our approach, we conduct computational experiments with certain criteria. The potential of the proposed approach is demonstrated by comparing to a well-known multi-objective evolutionary algorithm. Computational results have presented promise solutions for different sizes of problems and proved to be an innovative and efficient approach for many difficult-to-solve problems.

Construct the stable vendor managed inventory partnership through a profit-sharing approach

In real life, the vendor managed inventory (VMI) model is not always a stable supply chain partnership. This paper proposes a cooperative game based profit-sharing method to stabilize the VMI partnership. Specifically, in a B2C setting, we consider a VMI program including a manufacturer and multiple online retailers. The manufacturer provides the finished product at the equal wholesale price to multiple online retailers. The online retailers face the same customer demand information. We offer the model to compute the increased profits generated by information sharing for total possible VMI coalitions. Using the solution concept of Shapley value, the profit-sharing scheme is produced to fairly divide the total increased profits among the VMI members. We find that under a fair allocation scheme, the higher inventory cost of one VMI member increases the surplus of the other members. Furthermore, the manufacturer is glad to increase the size of VMI coalition, whereas, the retailers are delighted to limit the size of the alliance. Finally, the manufacturer can select the appropriate retailer to boost its surplus, which has no effect on the surplus of the other retailers. The numerical examples indicate that the grand coalition is stable under the proposed allocation scheme.     

Business-to-business integration: Applicability,benefits and barriers in the telecommunications industry

This paper statistically analyzes applicability of business-to-business integration (B2Bi), benefits from and barriers to electronic data interchange (EDI) and RosettaNet between major original equipment manufacturers and European operators in the telecommunications industry. Based on coordination costs and nine business processes, frequency of the business process and timeliness required in the business process have clearer positive influences on applicability of B2Bi than does accuracy required in the business process. Complexity of the business process does not have such a positive relation to this applicability. Comparison of 12 benefits and eight barriers between EDI and RosettaNet shows no considerable differences. RosettaNet yields only slightly higher direct benefits than EDI, whereas all indirect benefits from RosettaNet are significantly higher than indirect benefits from EDI. Surprisingly, barriers to RosettaNet are not lower than barriers to EDI although only a lack of knowledge on EDI or RosettaNet is a significantly higher barrier to RosettaNet.     

An effective heuristic for solving a combined cargo and inventory routing problem in tramp shipping

In this paper a vendor managed inventory (VMI) service in tramp shipping is considered. VMI takes advantage of introducing flexibility in delivery time and cargo quantities by transferring inventory management and ordering responsibilities to the vendor which in this case is a shipping company. A two-phase heuristic is proposed to determine routes and schedules for the shipping company. The heuristic first converts inventories into cargoes, thus turning the problem into a classic ship routing and scheduling problem. It then uses adaptive large neighborhood search to solve the resulting cargo routing and scheduling problem. The heuristic iteratively changes the cargoes generated to handle the customer’s inventories, based on the information obtained from an initial solution. Computational results are presented, discussed and compared with exact solutions on large realistic instances. The results reveal the potential savings from converting traditional contracts of affreightment to an integrated VMI service. The factors that influence the benefits obtainable through VMI are also analyzed.     

Effectiveness of vendor-managed inventory in the electronics industry: determinants and outcomes

This study used the extended limits-to-value model to frame four research hypotheses related to the effects of organizational size, employee involvement, and logistics integration on the expected and perceived values of vendor-managed inventory (VMI) as implemented in the electronics industry. Most of the findings supported the hypotheses. Specifically, that supply chain members working for organizations with high levels of employee involvement and logistics integration were more likely to realize the potential values of VMI. However, contrary to the notion that large organizations have more slack resources in technology adoption and implementation, VMI benefited small organizations most.
