Replenishment Policies for Multi-Product Stochastic Inventory Systems with Correlated Demand and Joint-Replenishment Costs
T his study analyzes optimal replenishment policies that minimize expected discounted cost of multi-product stochastic inventory systems. The distinguishing feature of the multi-product inventory system that we analyze is the existence of correlated demand and joint-replenishment costs across multiple products. Our objective is to understand the structure of the optimal policy and use this stru...
متن کاملAn Introduction to Joint Pricing and Inventory Management under Stochastic Demand
In this paper, we review the models of joint pricing-inventory management under demand uncertainty. Our focus is on establishing a unified modeling framework that incorporates both pricing and inventory decisions. It applies to different problem settings in this area with proper adaptations. In particular, we employ our modeling framework to five different key problems: (1) single period proble...
متن کاملConstraint multiproduct joint-replenishment inventory control problem using uncertain programming
An uncertain economic order quantity (UEOQ) model with payment in advance is developed to purchase high-price raw materials. A joint policy of replenishments and pre-payments is employed to supply the materials. The rate of demand is considered LR-fuzzy variables, lead-time is taken to be constant, and it is assumed that shortage does not occur in the cycles. The cycle is divided into three par...
متن کاملAn Innovative Heuristic for Joint Replenishment Problem with Deterministic and Stochastic Demand
Joint replenishment problem (JRP) is a common real problem which aims to minimize order cost and inventory holding cost. In this paper, classical, centralized and decentralized JRP models are discussed. An innovative heuristic to minimize the total cost is implemented for each model. This heuristic seeks to balance the order cost and the inventory holding costs. The results show that the innova...
متن کاملModels and Algorithms for the Dynamic-demand Joint Replenishment Problem
This paper deals with the problem of coordinated ordering of items having deterministic but time varying demands where there is a common ordering cost if one or more of these items are ordered in addition to individual items ordering costs. To solve this NP-hard problem we propose a number of heuristics. Also we report on a comparative study that we undertaken to evaluate the relative performan...
