A practical vehicle scheduling method has been developed based on a ge
netic algorithm hybridized with a specially developed high-speed opera
tions research (OR) algorithm. Test results show that this method quic
kly provides sufficiently optimized schedules for real-world problems.
For example, the method's schedules reduce the number of required veh
icles, and achieve a high loading rate, close observance of company's
internally set load limits, and excellent punctuality. This method is
much superior to human expert schedulers in terms of the quality of sc
hedules and the scheduling speed. With this method, distributors will
be able to make large cost reductions and win the confidence of custom
ers.
