| Popis: | Objective: This paper proposes a method to analyze the technical, commercial and social feasibility of software projects in environments of uncertainty. It allows working with multiple experts and multiple criteria and facilitates decision-making. Method: The proposal contains two phases, first the necessary information is collected and in second place projects are evaluated using 2-tuple linguistic representation model. The experts are selected by analyzing their curricular synthesis. The evaluation criteria are defined using the technique Focus Group and weighted in the interval (0,1) according to their importance. three domains are offered to express the preferences: numeric, interval-valued and linguistic. For aggregation extended arithmetic mean and weighted average extended are used, preventing the loss of information. A 2-tuple (feasibility, precision) is obtained as a result for each project. Results: The evaluation of P1 project was a very high feasibility with -0,33 of precision. The P2 project obtained a high feasibility with 0,38 of precision and P3 project achieved a medium feasibility with -0,21 of precision. Conclusions: This method is favorable for software projects feasibility analysis with presence of multiple experts and criteria, in environments of uncertainty. It tries heterogeneous assessments without loss of information. Their results are consistent and useful for decision makers. |
