Simulation-based Switching Algorithm for Inventory Management in a Multi-echelon Supply Chain

چکیده
Cyclic or non-cyclic planning policies are traditionally used to manage inventories in a multiechelon supply chain. Evaluation of the difference between performances of cyclic and non-cyclic planning policies allows analysing an efficiency of a specific planning policy at the product life cycle specific stage, and provides a control mechanism to switch from one to another policy. The paper is aimed is to present simulation-based switching algorithm that provide estimating the difference between the total costs of cyclic and non-cyclic planning policies with optimal parameters and decision making about application of an appropriate one. Simulation-based switching algorithm contains two phases: cost comparison analysis in the first phase, and advanced analysis based on additional costs of a cyclic solution (ACCS) in the second phase. A numerical example and a prototype of a switching module are described in the paper. Key-Words: non-cyclic and cyclic planning policies, multi-echelon supply chain, product life cycle, additional costs of cyclic solutions, and simulation-based switching.

متن کاملDetermination of a Desirable Inventory Policy in a three Echelon Multilayer Supply Chain with Normal Demand
Inventory control is one of the most important issues in supply chain management. In this paper, a three-echelon production, distribution, inventory system composed of one producer, a set of wholesalers and retailers is considered. Costumers' demands can be approximated by a normal distribution and the inventory policy is a kind of continuous review (R, Q). In this paper, a model based on stand...

This paper formulates a two-echelon single-producer multi-buyer supply chain model, while a single product is produced and transported to the buyers by the producer. The producer and the buyers apply vendor-managed inventory mode of operation. It is assumed that the producer applies economic production quantity policy, which implies a constant production rate at the producer. The operational pa...
