碩士 === 中華工學院 === 工業工程與管理研究所 === 85 === Combining both the characteristics of classic and modern control theory, fuzzylogic control (FLC) has the capability to deal with complex data by usingexpe-rt knowledge and logic inference. It has done a good job on qualitative syste-ms, and has been appliedwidely on many products in recent years. The output of FLC utilizes the input data from the controlled system. In-time adjustments of FLC keep the system operated properly in most cases. In somecases, too manycontrol actions may cause high operating cost. Choosing theright time to have a control action is thus an important issue. Using the algorithm of Extended Reliability Evaluation Framework (X-REF), the fuzzy reliability system proces-ses as a filter to choose only the meaningful control actions. In the case of aggregate production planning, the model proposed in this research successful-ly reduces the variance of work force level. It also provides space for manag- ers when making decisions, and enhancesthe flexibility of the FLC.
