Fuzzy Palmer scheduling for flow shops with more than two machines
In the past, we have demonstrated how fuzzy concepts can easily be used in the Johnson algorithm to manage uncertain scheduling on two-machine flow shops. This paper extends application to fuzzy flow shops with more than two machines. A new fuzzy heuristic flow-shop scheduling algorithm (the fuzzy Palmer algorithm) is then designed since optimal solutions seem unnecessary for uncertain environments. Also, the conventional Palmer algorithm is presented as a special case of the fuzzy Palmer algorithm with special assigned membership functions.
