García Villoria, Alberto; Corominas Subias, Albert; Nadal Solà, Adrià; Pastor Moreno, Rafael (Elsevier, 2018-01-01)
Article
Accés obertAssembly line balancing problems (ALBPs) are among the most studied combinatorial optimization problems due to their relevance in many production systems. In particular, the accessibility windows ALBP (AWALBP) may arise ... -
Solving the generalized apportionment problem through the optimization of discrepancy functions
Bautista Valhondo, Joaquín; Companys Pascual, Ramón; Corominas Subias, Albert (Elsevier, 2001-04)
Article
Accés obertOne of the ways to solve the classical apportionment problem (which has been studied chiefly in relation to the apportionment of seats in a chamber of representatives) is the optimization of a discrepancy function; although ... -
Solving the minmax product rate variation problem (PRVP) as a bottleneck assignment problem
Moreno Palli, Natalia; Corominas Subias, Albert (Elsevier, 2006-04)
Article
Accés obertIn this paper, we consider the minmax product rate variation problem (PRVP), which consists in sequencing copies of different products on an assembly line in such a way that the maximum value of a discrepancy function ... -
Solving the Response Time Variability Problem by means of a variable neighbourhood search algorithm
Corominas Subias, Albert; García Villoria, Alberto; Pastor Moreno, Rafael (2009-06-05)
Comunicació de congrés
Accés obertAbstract: The Response Time Variability Problem (RTVP) is a NP-hard combinatorial scheduling problem which has recently reported and formalised in the literature. This problem has a wide range of real-world applications ... -

García Villoria, Alberto; Pastor Moreno, Rafael; Corominas Subias, Albert (IOS Press, 2006-10)
Article
Accés obertThe Response Time Variability Problem (RTVP) is a combinatorial NPhard problem which has a wide range of real-life applications. It has recently appeared in the literature and has therefore not been widely discussed to ... -
Taking decisions on assignment of tasks with path dependent learning curves
Corominas Subias, Albert; Olivella Nadal, Jordi; Pastor Moreno, Rafael (2008-10)
Report de recerca
Accés obertPerformance in doing a task in the learning stage depends on the previous practice on other tasks –learning curve is path dependent. A mathematical program aimed to assign a set of tasks to a set of workers considering ... -
Technical note: relating to the parameter values given by Nelder and Mead in their algorithm
