The problems facing the aggragate stone industry in Zambia such as low capacity utilization, failure to meet customer requirements, unnecessarily high operating costs, poor inventory control practices, heavy borrowing and overall poor economic performance are as a result of subjective decision-making related to production planning. This is also true of the industry in nearly all member countries of the SADDC(Southern African Development Co-ordinating Conference) where quarry closures are not uncommon. As a solution to the problem of production planning and control in the crushed stone industry, this paper presents results of an application of the goal programming technique to a Zambian case study engaged in the production of limestone powder for the chemical industry. The formulation of a mathematical model for handling multiple objectives is discussed. The goal programming model can be used by management as a strategic decision support instrument. Results of the study show that over time work is related to the levels of demand for each product as well as the capacity utilization of the plant. The conflicts among the various goals of the short term production plan are identified. The study suggests that goal programming can provide an improved model to solve the problem of production planning in the crushed stone industry. |
