The impact of incentive-based programmes on job-shop scheduling with variable machine speeds

AbstractGiven the high demand for energy in the manufacturing industry and the increasing use of renewable but volatile energy sources, it becomes increasingly important to coordinate production and energy availability. With the help of incentive-based programmes, grid operators can incentivise consumers to adjust power demand in critical situations such that grid stability is not threatened. On the consumer side, energy-efficient scheduling models can be used to make energy consumption more flexible. This paper proposes a bi-objective job-shop scheduling problem with variable machine speeds that aims on minimising the total energy consumption and total weighted tardiness simultaneously. We use a genetic algorithm to solve the model and derive Pareto frontiers to analyse the trade-off between both conflicting objectives. We gain insights into how incentive-based programmes can be integrated into machine scheduling models and analyse the potential interdependencies and benefits that result from this integration.KEYWORDS: Job-shop schedulingenergy-efficient production planninggenetic algorithmsustainable manufacturingdemand response programmesincentive-based programmes AcknowledgementsThis paper is a revised and extended version of the conference paper ‘Energy-efficient job shop scheduling considering processing speed and incentive-based programmes’ that was presented at 10th IFAC Conference on Manufacturing Modelling, Management and Control in Nantes, France, 2022.
