This paper develops a new simulation method for vendor managed inventory (VMI) model based on fuzzy arithmetic in the supply chain (SC). The traditional VMI model has been successfully used to reduce the ‘‘Bullwhip Effect” in the SC. Thus, in real industry the VMI model can be observed that some variables/ parameters may belong to the uncertain factors. Therefore, the traditional VMI model may ...

the objective of this article is to develop an empirically based framework for formulating and selecting a vendor in supply chain. this study applies the fuzzy set theory to evaluate the vendor selection decision. applying analytic hierarchy process (ahp) in obtaining criteria weights and applied technique for order performance by similarity to idea solution (topsis) for obtaining final ranking...

The Inventory Routing Problem (IRP) involves the distribution of one or more products from a supplier to a set of customers over a discrete planning horizon. The version treated here, the so-called Vendor Managed Inventory Routing Problem (VMIRP), is the Inventory Routing problem arising when the replenishment policy is decided a priori. We consider two replenishment policies. The first is know...

This paper studies a single-product supply chain, in which the supplier needs to manage its own inventory to fulfill requests from a set of heterogonous retailers. The retailers’ requests are determined by the supplier in a fashion of vendor-managed inventory (VMI). Under a VMI arrangement, the supplier agrees to pay all the order setup costs and a portion of unit holding costs for the retailer...

In this paper, we extend the models in the literature [Lee, H.L., So, K.C., Tang, C., 2000. The value of information sharing in a two-level supply chain. Management Science 46 (5), 626–643; Raghunathan, S., Yeh, A.B., 2001. Beyond EDI: impact of continuous replenishment program (CRP) between a manufacturer and its retailers. Information Systems Research 12 (4), 406–419] to analyze the benefits ...

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 org...

We provide a broad characterization of the supply chain settings in which perfect coordination can be achieved with a simple wholesale pricing scheme based on constant unit wholesale prices or a single quantity discount scheme. We confine ourselves to two-echelon chains with a single supplier servicing a network of retailers who compete with each other by selecting retail prices (Bertrand compe...

This paper compares the bullwhip properties of a Vendor Managed Inventory (VMI) supply chain with those of a traditional “serially-linked” supply chain. The emphasis of this investigation is the comparative impact the two structures have on the “Bullwhip Effect” generated. Particular attention is paid to the manufacturer’s production ordering activities as demonstrated using a simulation model ...

The paper compares the expected performance of a Vendor Managed Inventory (VMI) supply chain with a traditional “serially-linked” supply chain. The emphasis of this investigation is the impact these two alternative structures have on the “Bullwhip Effect” generated in the supply chain. We pay particular attention to the manufacturer’s production ordering activities via a simulation model based ...

This paper proposes an adaptive fuzzy control application to support a vendor managed inventory (VMI). The methodology applies fuzzy control to generate an adaptive smoothing constant in the forecast method, production and delivery plan to eliminate, for example, the rationing and gaming or the Houlihan effect and the order batching effect or the Burbidge effects and finally the Bullwhip effect...
