COTS evaluation using modified TOPSIS and ANP

This paper models the COTS evaluation problem as an MCDM problem and proposes a five-phase COTS selection model, combining the technique of ANP (analytic network process) and modified TOPSIS (technique for order performance by similarity to idea solution). This article discusses using the ANP to determine the relative weights of multiple evaluation criteria. The modified TOPSIS approach is used to rank competing products in terms of their overall performance. To illustrate how the approach is used for the COTS evaluation problem, an empirical study of a real case is conducted. The case study demonstrates the effectiveness and feasibility of the proposed evaluation procedure. (c) 2005 Elsevier Inc. All rights reserved.
