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...

Food vs. biofuel: An optimization approach to the spatio-temporal analysis of land-use competition and environmental impacts

Cobuloglu, Halil I.; Büyüktahtakın, İ. Esra - In: Applied Energy 140 (2015) C, pp. 418-434

Biofuel production from food crops leads to debates about the increase in food prices and security of the food supply. On the other hand, biofuels derived from cellulosic (energy) crops offer positive environmental impacts. In this study, we develop a multi-objective mixed-integer optimization...

A multi-objective interactive system for adaptive traffic control

Dujardin, Yann; Vanderpooten, Daniel; Boillot, Florence - In: European Journal of Operational Research 244 (2015) 2, pp. 601-610

In this paper, we consider the problem of adaptive traffic control on single junctions with the three following objectives to be minimized: the total waiting time and the number of stops for private vehicles, and a public transport criterion. This problem being modeled as a multi-objective mixed...

Quantifying uncertainty on Pareto fronts with Gaussian process conditional simulations

Binois, M.; Ginsbourger, D.; Roustant, O. - In: European Journal of Operational Research 243 (2015) 2, pp. 386-394

Multi-objective optimization algorithms aim at finding Pareto-optimal solutions. Recovering Pareto fronts or Pareto …-to-evaluate functions is to appeal to metamodels. Kriging has been shown efficient as a base for sequential multi-objective optimization … and quantifying how much uncertainty remains on it at any stage of Kriging-based multi-objective optimization algorithms …
