An analysis of energy consumption and cost-effectiveness for overhead crane drive systems by using fuzzy multi-objective linear programming

The aims of this paper are to consider cost and energy consumption to solve overhead crane systems' setting issues. The main issue is that cranes use higher frequency handling equipment in heavy industry. In the overhead crane system setting issues, the determining factors, such as cost, load and energy consumption, are fuzzy. Moreover, decision makers must simultaneously consider real-world conflicting multi-objectives. In summary the question involves a fuzzy multi-objectives problem. Therefore, this paper adopted fuzzy multi-objective programming to construct a mathematical model aimed at minimizing cost and energy consumption with reference to the crane load, recovery period and budget, to carry out a crane system configuration. The model is used for a real problem to verify its correctness. Finally, this study provides a reference for decision makers to purchase crane device configurations.
