One important issue in the analytic hierarchy process (AHP) is confirming the consistency of comparison matrix to verify the logical respondent opinion. As inconsistent comparison matrix cannot be used as reference to make decisions, this paper proposes a method using an ant algorithm to modify an inconsistent pairwise weight matrix to be consistent in AHP,(More)
This paper presents a modified bee colony optimization (BCO) by pattern reduction to reduce the computation time, called BCOPR. Although BCO was robustness optimization, but likes the other algorithm for solving optimization problem, BCO has many reduncation computations on its convergence process, as a consequence, it will more computation time.

Analytic hierarchy process (AHP) is a decision making tool regarding the criteria analysis to obtain a priority alternative. One of the important issues in comparison matrix of AHP is the consistency. The inconsistent comparison matrix cannot be used to make decision. This paper proposes an algorithm using a modified BicriterionAnt to pursue two objectives(More)
