A multiobjective model was proposed to minimize energy consumption, machine failure rate, and total completion time of jobs in a single machine manufacturing environment given that machine failure rates are different during idle, setup, and processing operation modes. Turning off the machine during the interarrival period between two consecutive jobs will save some energy in comparison to running the machine in idle mode. However, it may impact the reliability of the machine adversely due to resulting shocks during the setup (turn off/on) process. Energy consumption and total completion time minimization and reliability maximization are conflicting objectives which were considered simultaneously in this study. The proposed multiobjective model was solved using a weighted approach and sensitivity analysis was performed to investigate the impact of variations of some parameters on the model.
