Abstract

In this paper, we propose a new hybrid algorithm to solve the Job Shop Problem. Our algorithm, called Evoluntionary-Taboo uses an Evolutionary Algorithm (EA) to enhance results obtained by one of the best Taboo algorithms for this problem. We tested the algorithm on the benchmark problems for which the taboo algorithm returned its worst results. On average, we improved taboo results by 2.9%. The results were under one percent from the best known results for these problems.
