A Fuzzy Rule for Improving the Performance of Multiobjective Job Dispatching in a Wafer Fabrication Factory

Table 1

Some existing fuzzy dispatching rules.

References	System type	Rules/inputs/outputs	Number of objectives
Xiong et al. [4]	TSK	2/2/1	2 (average cycle time, lateness)
Benincasa et al. [5]	Mamdani	27/3/1	2 (average cycle time, WIP level)
Lee et al. [9]	Single-rule-based	2/4/1	2 (average cycle time, cycle time standard deviation)
Tan and Tang [10]	Mamdani	8/4/1	3 (throughput, average cycle time, no. of vehicles)
Dong and Liu [11]	ANFIS	16/4/1	1 (average cycle time)
Tsai and Chen [12]	Fusion	4/5/1	4 (average cycle time, cycle time standard deviation, maximum lateness, number of tardy jobs)
