Abstract

Task allocation and the control of equipment interval states significantly impact energy consumption in workshops, making them crucial for achieving overall energy savings. However, current asynchronous optimization methods face limitations due to the strong constraints imposed by task allocation on equipment state control. This study proposes a scheduling method that synchronously optimizes equipment tasks and interval state control. Firstly, the influence of equipment states (idle, standby, stop) on energy consumption is analyzed within different interval times resulting from task allocation. By examining the relationship between changes in equipment interval states and energy fluctuations, three energy-saving scheduling strategies that integrate state control are developed. Secondly, relevant variables related to interval states and energy consumption are extracted to establish an energy-saving scheduling model for synchronous optimization. An improved multi-objective whale optimization algorithm (MOWOA) is then designed, incorporating scheduling adjustments and energy-saving strategies into chromosome encoding to address the energy-saving scheduling model. Finally, a case study involving the machining of engine parts demonstrates the effectiveness of the proposed method. The results indicate that the generated Gantt chart accurately reflects both equipment task allocation and interval state control outcomes.
