In this paper, a multi-objective model is proposed to minimize energy consumption and total completion time, and to maximize reliability on a single machine. In this problem, jobs arrive over time, and their release dates are known. As a result, one must decide if turning off/on the machine or keeping the machine running idle will be more beneficial in terms of total energy consumption and reliability, since the impacts of idling and turning off/on operations affect the machine's lifetime differently. The proposed model is solved using the multi-objective optimization approach, and some sensitivity analysis is performed to gain insight.
