Real-Time Energy-Efficient Scheduling of Jobs and Maintenance in the Industry 4.0

摘要

Industry 4.0 is a new approach to organizing the manufacturing process. This new industry asserts itself as the convergence of the virtual world, digital design, management (operations, finance and marketing) with the products and objects of the real world. The use of real-time information in production scheduling decisions and energy-constrained maintenance is becoming possible thanks to new developments in information technology and industrial computing, such as Industry 4.0. The gradual implementation of Industry 4.0 in industries has led to an increase in the amount of energy consumed in industrial systems to operate various machines. In addition, the computational efficiency of these real-time embedded systems (RTES) depends solely on the timely completion of tasks. Performing production and maintenance tasks with reduced energy consumption within critical timeframes is a challenge for designers. However, energy efficiency and on-time delivery are two conflicting goals, since the former is only achieved with a significant trade-off of the latter. In this paper, we propose a new flowchart of the Real-Time energy-efficient Scheduling (RTEES) of Production and Maintenance System in Industry 4.0 based on optimization.
