The purpose of this study applies Technology Acceptance Model(TAM) to better understand the role of antecedents leading to intention of VMI use. The findings are as follows. First, the model that applied VMI, a SCM information technology, to TAM is appropriate for measuring and analyzing the acceptance intention of organizational members, VMI users. Second, higher satisfaction in VMI system factors led to a greater level of perceived usefulness and perceived ease of use of VMI. Third, higher satisfaction in VMI cooperation factors led to a greater level of perceived ease of use of VMI. Fourth, the perceived ease of use of VMI had an impact on the perceived usefulness of VMI, similar to the findings of other studies. Fifth, the perceived ease of use of VMI had a positive impact on intention of the continuous VMI use.

Purpose - Many researchers analyze VMI as a supply chain collaboration program to reveal its true value. Most of them focus on the dyadic relationship in two stage supply chain systems. This study examines the effect of VMI when it is applied to the different parts of three stage supply chain systems. Research design, data, and methodology - Based on three stage supply chain, this study compares three different systems including full VMI, partial VMI, and non-VMI by using mathematical models. The performances of three systems are compared with the numerical examples of the proposed supply chain models. Results - The numerical examples reveal that full VMI where the manufacturer controls inventories at all stages outperforms any other systems in terms of the system profit and enables all individual members to gain greater profits than non-VMI. Meanwhile, under partial VMI where VMI is implemented between the wholesaler and retailer, only these two members improve their performances and the manufacturer who does not belong to VMI makes less profit than even under non-VMI. This study also examines the impact of market size and profit margin on the system performance. Conclusions - The result of this study supports the common belief that VMI secures the best result when it is applied to the entire supply chain system. The additional findings from the numerical analysis are discussed.

Purpose: This study investigates the influence of VMI on the supply chain performance over time. By examining each supply chain member's ongoing performance, this study figures out how VMI allows the vendor to overcome the initial loss and eventually provides the benefit to every supply chain member. Research design, data, and methodology: The proposed mathematical model describes the supply chain system where a manufacturer and a retailer make the operational decisions to maximize their own profits. By using the numerical examples with arbitrary data, VMI and non-VMI are compared in terms of their profit changes over time. Results: The numerical analysis shows that VMI results in greater overall profits for both manufacturer and retailer than non-VMI, while the manufacturer make a loss in the early stage of VMI implementation. This study also examines the impacts of certain conditional factors on the performance of VMI. Conclusions: This study supports the idea that VMI leads to manufacturer's initial loss but it brings greater profits to both manufacturer and retailer than non-VMI after all. In addition, the result of this study provides the managerial implications about the particular condition that allows VMI to achieve a significant financial performance improvement over non-VMI.

Purpose - This study reviews the past studies that have researched Vendor Managed Inventory (VMI) as a well-known supply chain collaboration program. The main goals of this study are to figure out how VMI brings significant benefits to the supply chain system and suggest additional areas that future studies would address to discover the true nature of VMI. Research design, data, methodology - This study conducts literature reviews on numerous studies that have researched VMI. The past studies are classified in terms of several main issues that have been commonly addressed by many researchers. This study also identifies three key collaborative features of VMI, which possibly explain why VMI improves the supply chain performance. Results - This study finds out that most past studies focused on a limited research issues about VMI. Many researchers have considered integrated decision making and information sharing to be key features that enables VMI to improve the supply chain performance. Conclusions - Based on the findings from the literature review, this study suggests that future studies on VMI take account of new research issues and pay attention to cost payment that researchers have rarely addressed.

최근 소매점 공급사슬을 전체적인 관점에서 효율적으로 운영하기 위하여 공급자가 소매점의 재고를 관리하는 공급자 주도 재고관리(Vendor Managed Inventory; VMI)정책의 도입이 확산되고 있다. VMI 정책은 소매점에서 직접 수행하는 재고관리(Retailer Management Inventory; RMI)와는 달리 소매점의 재고수준에 대한 의사결정과 재고유지에 대한 재정적인 책임이 소매점으로부터 공급자에게 옮겨진다. 이에 따라 소매점은 공급자로부터 수시로 재고를 보충 받게 되고 주문절차는 사라진다. 또한 재고공간의 크기를 줄일 수 있게 된다. 공급자 또한 전체 소매점에 대한 효율적인 분배로써 비용절감의 효과를 기대할 수 있게 된다. 본 연구에서는 품절을 고려하며 소매점의 판매수요가 확정적인 상황에 대하여 RMI와 VMI에 대한 총비용을 최소화하는 수리모델을 통해 총비용 관점에서 RMI와 VMI정책을 비교하고자 한다. 계산실험을 통해 RMI와 VMI의 총비용 변화에 민감한 요인들을 분석하였고 VMI 적용으로 총비용을 절감시키기 위한 조건을 모색하였다. 실험결과, VMI의 적용은 항상 총비용 절감 효과를 나타내는 것이 아님을 확인 하였고 RMI에 대한 VMI의 총비용 증감효과는 RMI 정책의 소매점 주문비와 VMI정책의 소매점 재고공간의 크기 변화에 가장 크게 영향을 받는 것으로 나타났다. 이를 토대로 간단한 소매점 공급사슬에 대해서 VMI의 총비용 감소조건을 제시하였다.

Purpose: Focusing on the role of the special contract to collaborate the supply chain operations, this study investigates how the revenue sharing contract affects the performance of Vendor Managed Inventory (VMI). Research design, data, and methodology: The optimization model is formulated to represent two stage supply chain system where the supplier and retailer manage the operations to maximize their own profits. Three supply chain models including the traditional system, VMI, and VMI with revenue sharing contract are compared in the numerical examples. Results: According to the numerical analysis, the entire supply chain system has greater profit under VMI than the traditional system, while VMI alone sacrifices the supplier's profit. With the proper sets of revenue share ratio and wholesale price discount rate, VMI with revenue sharing contract results in the increased profit for both supplier and retailer compared with VMI alone as well as the traditional system. Conclusions: The numerical examples imply that VMI, when it is combined with the revenue sharing contract, can be the effective collaboration program that satisfies every supply chain member. To make VMI with revenue sharing contract to be fair to all supply chain members, they need to agree on the appropriate contract content.

Vendor Managed Inventory(VMI) is a distribution channel system where the inventory at the retailer is monitored and managed by the manufacturer or vendor. By pushing the decision making responsibility further up the supply chain and centralizing the replenishment decision, the vendor can help the entire supply chain be more competitive. The purpose of this research is to explore the factors influencing the adoption of VMI by Korean manufacturers. This research proposes the IT readiness, operating cost, and information sharing as antecedents of burden for VMI, and collected the survey responses from the small-to-medium manufacturers. The statistical results indicate that only the operating cost has a significant impact on the adoption of VMI. However it has also been found that the IT readiness and information sharing have a significant effect on the operating cost. Thus indirectly influence the adoption of VMI. As a conclusion, the academic and practical implications of these findings are discussed.
