An interactive decision support system for an aggregate production planning mod...
Gomes da Silva, Carlos; Figueira, José; Lisboa, João; Barman, SamirIn this paper, we present an aggregate production planning (APP) model applied to a Portuguese firm that produces construction materials. A multiple criteria mixed integer linear programming (MCMILP) model is developed with the following performance criteria: (1) maximize profit, (2) minimize late orders, and (3) minimize work force level changes. It includes certain operational features such as partial inflexi...
A Scatter Search Method for the Bi-Criteria Multi-dimensional 0,1-Knapsack Prob...
Gomes da Silva, Carlos; Clímaco, João; Figueira, JoséThis paper presents a scatter search (SS) based method for the bi-criteria multi-dimensional knapsack problem. The method is organized according to the usual structure of SS: (1) diversification, (2) improvement, (3) reference set update, (4) subset generation, and (5) solution combination. Surrogate relaxation is used to convert the multi-constraint problem into a single constraint one, which is used in the di...
