PRODUCTION PLANNING AND CONTROL OF OPERATIONAL COST OF MANUFACTURING INDUSTRIES IN NIGERIA

ABSTRACT   

Scarce resources must be properly planned and controlled using scientific approaches to control cost of allocating them. The root cause of undue production and high cost of production can neither be easily traced using traditional method nor past experience even computer systems. This study used Linear Programming Model to plan production of Products of Adama Beverages Limited. The aim was to apply Linear Programming Model to determine the products and how many to produce to ascertain Planning and Control of Operational Cost. Secondary Data was collected on supply of products, interview and observation on production process of the company was made, and Linear Programming Model was formulated for the problem. Results were derived using TORA Software. The best products, which will maximize profit, were determined by the model and the company is recommended to embark strictly on scientific approaches to plan production in order to control operational cost.
