Energy Consumption Optimization in Three-Machine Bernoulli Serial Lines

Abstract

High energy consumption is detrimental for reducing manufacturing cost and improving competitiveness of manufacturing enterprises. In this paper, the problem of reducing energy consumption in a three-machine Bernoulli serial line is formulated and solved. Specifically, first, based on the aggregation method, structural characteristics of the optimization model are analyzed and thus, the problem is transformed; then, with the efficiency of the first machine fixed, based on the results of the energy consumption optimization model in the two-machine line, the optimization model is further analyzed and solved; finally, the property of the objective function with respect to the efficiency of the first machine is analyzed and based on the property, an algorithm is designed to solve the energy consumption optimization problem in the three-machine Bernoulli serial line.
