Abstract:

Increased carbon dioxide emissions and energy consumption have increased interest in energy-effective planning problems. In this study, a multi-purpose energy efficient one-machine charting problem has been addressed by the speed adjustment method in order to ensure energy savings. In literature, in the speed adjustment method, when the machine is running at high speed, the energy consumption rate increases but the work is completed in a shorter time. When the machine is running at low speed, the energy consumption rate is reduced but the time of completion of the work is also extended. In the study, the objective functions are the reduction of the total amount of energy consumed and the number of delayed work. The problem is defined by the drawing problem in a manufacturing enterprise that produces plastic pieces. The work has a line-dependent preparation time, and the preparation time of a work depends on the work completed before it. A mathematical model is proposed. The method of e-limit has been used to solve the problem with multiple purposes. With the use of the relevant method, all Pareto effective solutions for small-dimensional problems are achieved. But as a result of the NP- difficult structure of the problem, a multi-purpose intuitive algorithm was proposed to solve large-scale problems. The success of the suggested algorithm is shown by comparison with the NSGA II algorithm.
