Marius Rădulescu, Constanța Zoie Rădulescu · Studies in Informatics and Control · 2015
The paper presents a minimum risk model, inspired from the financial portfolio theory, for the selection of a software vendor.The performance of the software products offered by potential software vendors is evaluated by several experts regarding several criteria.The minimum risk model has several constraints.One of the constraints is a complementarity constraint.Other constraints are connected with the available budget and the expected performance of the software products.A procedure for solving the minimum risk model is presented and a numerical example is analyzed.
