Service and repair companies, big stores, industries and power companies having complex issues on inventory brought this idea for solution. The inventory department of PHCN generating unit has obsolete and sometimes non-availability of materials. The company faces maintenance, repairs, replacement demands and outage-related problems. In order to cater for these demands, some classifications that would aid PHCN in making effective decisions as regards spare or service parts were made. This research has developed inventory control system that provides automated inventory management system and graphical interface ability for decision making. This is to “right-size” inventories such that the total level of inventory held can be reduced and replenished without exposing the company to risk of stock-out. The system is a model for dynamic supply chain management using spare parts inventory policy tools to enable PHCN to dynamically perform continuous review, one to one lot, service differentiation, backordering, demand lead time, threshold rationing and clearing mechanism.
