Abstract: In this paper, we consider single-vendor–multi-buyer Consignment Stock Policy (CSP) inventory model which is a distinctive flavour of Vendor Managed Inventory (VMI). Four different models have been formulated using Genetic Algorithm (GA) to minimise joint total expected cost of vendor and buyer and simultaneously optimise other decision variables such as quantity transported, number of transport operations, delay deliveries and buyer maximum and minimum stocks under stochastic environment. Numerical examples are presented to illustrate the proposed models, and the effects of changes on the cost and system parameters on the inventory are studied by using sensitivity analysis. To solve the iterative procedure involved, the GA is coded in VC++.
