This paper describes the use of parallel multipopulation genetic algorithms
(GAs) to meet the dynamic nature of job-shop scheduling. A modified geneti
c technique is adopted by using a specially formulated genetic operator to
provide an efficient optimisation search. The proposed technique has been s
uccessfully implemented using the programming language MATrix LABoratory (M
ATLAB), providing a powerful tool for job-shop scheduling. Comparisons indi
cate that the proposed genetic algorithm has successfully improved upon the
solution obtained from conventional approaches, particularly in coping wit
h jobshop scheduling.
