Consignment inventory (CI) is a supply chain business partnership where the customer orders to the vendor, but delays paying for goods. In CI, like the traditional systems, each member has authority over the timing and quantity of replenishments; however, these systems differ in time of transferring ownership. Previous researches showed different approaches for delay in payment in customer mana...

This paper describes four computer programs that perform what were formerly management-decision functions in inventory scheduling. The first program solves the classical EOQ problem (uniform inventory usage) with quantity discounts. The second program, Economic Requirement Batching (ERB), uses dynamic programming, a heuristic search algorithm, and the relation between shipment size and material...

The purpose of this paper is to develop a multi-item economic order quantity (EOQ) model with shortage for a single-buyer single-supplier supply chain under green vendor managed inventory (VMI) policy. This model explicitly includes the VMI contractual agreement between the vendor and the buyer such as warehouse capacity and delivery constraints, bounds for each order, and limits on the number ...

T work is motivated by the need to solve the inventory routing problem when implementing a business practice called vendor managed inventory replenishment. With vendor managed inventory replenishment, vendors monitor their customers’ inventories, and decide when and how much inventory should be replenished at each customer. The inventory routing problem attempts to coordinate inventory replenis...

In this paper, an integrated inventory model is developed from the perspective of a single vendor and multi-buyers for deteriorating items under fuzzy environment and inflation. In the development of the model, it is assumed that all costs parameters, demand and the production rates are imprecise in nature; they are represented by the trapezoidal fuzzy numbers, as these parameters are not const...

A major issue in supply chain inventory management is the coordination of inventory policies adopted by different members in a supply chain including suppliers, manufacturers, distributors, etc. This paper presents a fractal-based approach for inventory management in order to minimize inventory costs and smooth material flows between supply chain members while responsively meeting customer dema...

This paper develops a more general production-inventory model for a single-vendor–single-buyer integrated system. Unlike the hitherto existing production-inventory models for the vendor–buyer system, the present model neither requires the buyer’s unit holding cost greater than the vendor’s nor assumes the structure of shipment policy. Secondly, the model is extended to the situation with shorta...

This paper aims to enable the decision maker of an integrated vendor–buyer system, under Consignment Stock (CS) policy, to make the optimal/sub-optimal production/replenishment decisions where the buyer places a space limitation to the vendor and the lead-time is controllable with an extra investment. Within any production cycle, the vendor produces at a finite rate and ships the outputs to the...
