Planiranje zbiranja blaga v skladišču s hevrističnimi algoritmi

Uršič, Jakob (author), Bratko, Ivan (mentor)

Planiranje zbiranja blaga je smiseln proces v vsakem skladišču. V okviru te naloge je bil razvit simulator enostavnega skladišča, na katerem lahko s pomočjo algoritma A* generiramo plane za pobiranje vnaprej določene količine blaga za enega ali več robotov. Način dodeljevanja prioritete pri preiskovanju stanj je v veliki meri odvisen od hevrističnih ocen. Implementirali smo pet načinov za izračun hevrističnih ocen in jih preizkusili na primerih z različnimi lastnostmi, ter z različnim številom robotov. Dobljene rezultate smo analizirali, ter opozorili na morebitne pomanjkljivosti posameznih hevristik.

• Title: The planning of order picking in a warehouse by heuristic algorithms

Abstract

Planning of order picking is essential process in every warehouse. In this thesis, we developed a simple warehouse simulator, which allows us to do various searches on path finding for a certain amount of items for one or more robots, using the A* algorithm. Heuristic guidance of search is mainly based on heuristic evaluation. We have implemented five different heuristic estimates, which we tested experimentally on examples with different warehouse configurations and with different numbers of robots. We also analysed the results and pointed out the drawbacks of each heuristic.
