A review of interactive methods for multiobjective integer and mixed-integer programming

- M. J. Alves, J. Clímaco
- Computer Science, Mathematics
- Eur. J. Oper. Res.
- 1 July 2007

This paper makes a review of interactive methods devoted to multiobjective integer and mixed-integer programming (MOIP/MOMIP) problems. The basic concepts concerning the characterization of the… Expand

A bicriterion shortest path algorithm

- J. Clímaco, E. Martins
- Mathematics
- 1 December 1982

Abstract Among the network models, one of the more popular is the so called shortest path problem. This model is used whenever it is intended to minimize a linear function which represents a distance… Expand

Additive aggregation with variable interdependent parameters: the VIP analysis software

- L. Dias, J. Clímaco
- Computer Science
- J. Oper. Res. Soc.
- 1 September 2000

We consider the aggregation of multicriteria performances by means of an additive value function under imprecise information. The problem addressed here is the way an analysis may be conducted when… Expand

Capacitated single allocation hub location problem - A bi-criteria approach

- Maria da Graça Costa, M. E. Captivo, J. Clímaco
- Computer Science, Mathematics
- Comput. Oper. Res.
- 1 November 2008

A different approach to the capacitated single allocation hub location problem is presented. Instead of using capacity constraints to limit the amount of flow that can be received by the hubs, we… Expand

Capacitated dynamic location problems with opening, closure and reopening of facilities

- J. Dias, M. E. Captivo, J. Clímaco
- Economics
- 1 October 2006

In this research report three capacitated dynamic location problems with opening, closure and reopening of facilities are formulated and primal-dual heuristics are described that can solve those… Expand

ELECTRE TRI for Groups with Imprecise Information on Parameter Values

- L. Dias, J. Clímaco
- Mathematics
- 1 September 2000

ELECTRE TRI is a well-known method to assign actions to predefined ordered categories, considering multiple criteria. Using this method requires setting many parameters, which is often a difficult… Expand

An Interactive Method for 0-1 Multiobjective Problems Using Simulated Annealing and Tabu Search

- M. J. Alves, J. Clímaco
- Computer Science
- J. Heuristics
- 1 August 2000

This paper presents an interactive method for solving general 0-1 multiobjective linear programs using Simulated Annealing and Tabu Search. The interactive protocol with the decision maker is based… Expand

An aggregation/disaggregation approach to obtain robust conclusions with ELECTRE TRI

- L. Dias, V. Mousseau, J. Figueira, J. Clímaco
- Computer Science, Mathematics
- Eur. J. Oper. Res.
- 16 April 2002

ELECTRE TRI is a well-known method to assign a set of alternatives to a set of predefined categories, considering multiple criteria. Using this method requires setting many parameters, which is often… Expand

Resolving inconsistencies among constraints on the parameters of an MCDA model

- V. Mousseau, J. Figueira, L. Dias, Carlos Gomes da Silva, J. Clímaco
- Computer Science, Mathematics
- Eur. J. Oper. Res.
- 16 May 2003

We consider a framework where decision makers (DMs) interactively define a multicriteria evaluation model by providing imprecise information (i.e., a linear system of constraints to the models… Expand

Solving bicriteria 0-1 knapsack problems using a labeling algorithm

- M. E. Captivo, J. Clímaco, J. Figueira, E. Martins, J. L. Santos
- Mathematics, Computer Science
- Comput. Oper. Res.
- 1 October 2003

This paper examines the performances of a new labeling algorithm to find all the efficient paths (or non-dominated evaluation vectors) of the bicriteria 0-1 knapsack problem. To our knowledge this is… Expand
