Manufacturing-to-sale planning model for fuel oil production

The fuel oil refinery production industry, in Taiwan has entered a complete ly competitive free open market. In such an environment there exist a varie ty of uncertain factors, and a traditional production planning model will n ot be able to deal with the new situation. This study develops a responsive and flexible manufacturing-to-sale planning system to deal with uncertain manufacturing factors. The major objective of this study, is to model the p roblem of the uncertain nature faced by the Chinese Petroleum Corporation ( CPC) and to establish a manufacturing-to-sale planning model for solving th e problem. A linear programming technique is suggested for developing the o ptimal strategy for use in production plans. Fuzzy, theory is adopted for d ealing with demand/cost uncertainties. A possibilistic linear programming m odel is thus formulated in this study. The possible uncertain fluctuations on demand/cost are included in the model. Therefore, the strategy, for crea ting maximum profit for the company, can be obtained via the proposed model ling procedures.
