Material management aims to manage materials in an optimum manner to provide a pre-decided service to customers at minimum cost. It involves planning, sourcing, purchasing, storing, and controlling the flow of materials. Key functions include purchasing, stores management, and inventory control. Purchasing objectives are to avail materials at minimum cost while ensuring continuous production. Inventory control aims to provide adequate supply without shortages at optimal investment. Techniques like ABC analysis, VED analysis, and EOQ are used to classify items and determine optimal order quantities.
