The material of Color Filter (CF), which is a critical component of TFT-LCD and regarded as a very high share of the material cost, possesses the attributes of various set-up periods and expiration periods. Together with the oligopoly situation in the market of the critical components, the production of TFT-LCD is limited by its material supply. Therefore production planning and material requirement planning are seriously emphasized. Thereby this research targets the manufacture of CF and discusses its material requirement planning. Taking the mid-term orientation of a manufacture planning department, this research establishes the constraints that consider the up-stream supplier capacity, the material expiration, factory technology and productivity, and the objective function that examines minimum average inventory. It also proposes a heuristic algorithm to tackle the coordination problems between the manufacture department and the purchase department in the CF industry. Finally, the numeric examples are applied to contrast the outcomes of the algorithm and the optimized solution, so that the verification of the algorithm is able to derive.
