Single Machine Control for Energy Consumption Analysis in Bernoulli Serial Lines

Abstract

The green development of the manufacturing is supported by energy conservation and environmental protection policies. The implementation of strategies has gradually expanded from a single field to multiple fields. These changes improve quality of products, innovation ability and efficiency of resource allocation of manufacturing systems. In recent years, reducing energy consumption has become the focus of both industry and academics. In order to save energy, we consider switching on/off a machine in the production lines when certain thresholds of buffers are reached. In this paper, we investigate Bernoulli serial lines with buffers having limited capacity which run finite production. Mathematical model of the three-machine line which produce finite products is established and analytical methods of calculating production rate, consumption rate, blocking probability, starvation probability, completion time and energy consumption are proposed. Markovian approach is adopted in three-machine lines analysis. Meanwhile, simulation is used to analyse serial lines that have numerous machines.
