The Medium-Term Capacity Planning Problem for TFT-LCD Industry: An Application of Fuzzy Bilevel Programming

Yin-Yann Chen

Abstract—In this paper, the strategic single-stage multi-plant capacity planning issues for TFT-LCD panel industry is discussed. The TFT-LCD panel manufacturing is divided into array, cell, and module process. As the array has long production lead time, huge capacity expansion costs, array process becomes a bottleneck in the TFT-LCD manufacturing process. Therefore, how to determine the time point of capacity expansion and capacity allocation decisions will be an important issue. This paper uses bilevel programming to split this capacity problem into two levels (inventory and production), and applies fuzzy approach to solve it. Finally, through practical examples to illustrate the feasibility of fuzzy bilevel programming, and compared with the fuzzy mathematical programming. The results show that when production environment have hierarchical characteristics, applying fuzzy bilevel programming, the performance index for capacity planning is better.

Index Terms—TFT-LCD, capacity planning, bilevel programming, fuzzy approach.
