A hybrid EOQ and fuzzy model to minimize the material inventory in ready mixed concrete plants

Abstract

In almost all countries, a major percentage of the manufactured cement and aggregates is used in Ready-Mixed Concrete (RMC) plants. Therefore a material inventory control system is needed to form a consumption pattern for this material to optimize warehousing cost and ordering in RMC plants. Such a material inventory control system of batching plants could be applied as an approach for optimal estimation of the tanks required for storage and feeding of material. In this research, a material inventory control system of batching plants has been developed by Fuzzy Logic (FL) with Economic Order Quantity (EOQ) model of inventory control. The optimal order quantity of raw materials in batching plant can be predicted with fuzzy logic.
