Abstract

This research study focuses on solving a multi-objective job scheduling problem on a single machine. This problem involves the summation of four objective functions namely the total flow time ( ), tardiness ( ), earliness ( ), and late work ( ) of each of the n jobs with unequal release dates . This is formulated as . 

We present some special cases that yield optimal solutions. also, we propose a branch and bound algorithm in order to find the exact (optimal) solution for it, by derive and use a good lower, and using some heuristics methods to find the upper bound of seven including Gray Wolfe algorithm (GW), and Bat algorithm (BAT), this algorithm was given to find the optimal solution for problems of size up to 17 functions.
