Generating Optimised MRP Lot Sizes Using Genetic Algorithm : Considering Supplier Deals

Material requirement Planning (MRP) is the process of determining the detailed order release policy for parts, components and material needed to produce end products to a required production plan at minimum total cost. The objective of this paper is to present a method to generate optimised MRP solutions using the genetic algorithm to multiproduct, multi-period lot-sizing problems with supplier discounts/deals and storage capacity limitations. Demand for products is assumed known. Keywords—MRP; Genetic Algorithm; GA; Lot Sizing; Capacity Constraints; Chromosome; Heuristic Search; POR; ERP
