A hybrid artificial bee colony algorithm for the fuzzy flexible job-shop scheduling problem

A hybrid artificial bee colony (HABC) algorithm is proposed in this paper for solving the fuzzy flexible job-shop scheduling problem (FFJSP). First, the HABC utilises multiple strategies in a combined way to generate the initial solutions with certain quality and diversity as the food sources, and applies the left-shift decoding scheme to convert solutions to active schedules. Second, the exploitation search procedures based on the crossover...
