Reduction of carbon emissions and project makespan by a Pareto-based estimation of distribution algorithm

Zheng, Huan-yu; Wang, Ling - In: International Journal of Production Economics 164 (2015) C, pp. 421-432

Due to the increasing concerns about global warming, low-carbon production has been a hot topic around the world. In this paper, carbon emissions reduction and project makespan minimization are considered simultaneously. To formulate the problem, a multi-objective multi-mode resource-constrained...

Selecting a supplier portfolio with value, development, and risk consideration

Hosseininasab, Amin; Ahmadi, Abbas - In: European Journal of Operational Research 245 (2015) 1, pp. 146-156

This paper introduces a novel two-phase supplier selection procedure. Unlike most supplier selection researches, which are decisive based on supplier eligibility at the time of the decision making, the proposed method is based on the long term trend of value, stability, and relationship of...

An elitism based multi-objective artificial bee colony algorithm

Xiang, Yi; Zhou, Yuren; Liu, Hailin - In: European Journal of Operational Research 245 (2015) 1, pp. 168-193

In this paper, we suggest a new multi-objective artificial bee colony (ABC) algorithm by introducing an elitism strategy. The algorithm uses a fixed-size archive that is maintained based on crowding-distance to store non-dominated solutions found during the search process. In the proposed...

A two phase approach for the bi-objective non-convex combined heat and power production planning problem

Rong, Aiying; Figueira, José Rui; Lahdelma, Risto - In: European Journal of Operational Research 245 (2015) 1, pp. 296-308

In this paper, we deal with the bi-objective non-convex combined heat and power (CHP) planning problem. A medium and long term planning problem decomposes into thousands of single period (hourly) subproblems and dynamic constraints can usually be ignored in this context. The hourly subproblem...

A multi-objective approach for optimal prioritization of energy efficiency measures in buildings: Model, software and case studies

Karmellos, M.; Kiprakis, A.; Mavrotas, G. - In: Applied Energy 139 (2015) C, pp. 131-150

Buildings are responsible for some 40% of the total final energy consumption in the European Union and about 40% of the world’s primary energy consumption. Hence, the reduction of primary energy consumption is important for the overall energy chain. The scope of the current work is to assess...
