Job-shop production scheduling with reverse flows

Abdeljaouad, Mohamed Amine; Bahroun, Zied; Omrane, Anissa; … - In: European Journal of Operational Research 244 (2015) 1, pp. 117-128

In this paper, we conduct a study of the job-shop scheduling problem with reverse flows. This NP-hard problem is characterized by two flows of jobs that cover the same machines in opposite directions. The objective is to minimize the maximal completion time of the jobs (i.e., the makespan).

Optimal electricity dispatch on isolated mini-grids using a demand response strategy for thermal storage backup with genetic algorithms

Neves, Diana; Silva, Carlos A. - In: Energy 82 (2015) C, pp. 436-445

The present study uses the DHW (domestic hot water) electric backup from solar thermal systems to optimize the total electricity dispatch of an isolated mini-grid. The proposed approach estimates the hourly DHW load, and proposes and simulates different DR (demand response) strategies, from the...

Optimisation of the capacity and the dispatch of decentralised micro-CHP systems: A case study for the UK

Merkel, Erik; McKenna, Russell; Fichtner, Wolf - In: Applied Energy 140 (2015) C, pp. 120-134

Cogeneration of heat and electricity constitutes an important pillar in energy and climate policy. The optimal dimensioning and operation of residential micro-combined heat and power (mCHP) systems is an important area of ongoing research, especially because these systems are prohibitively...
