PENA ABREU, Marieta; GARCIA VACACELA, Roberto; RODRIGUEZ RODRIGUEZ, Carlos R  e  PINERO PEREZ, Pedro Y. Fuzzy economic criteria for software projects feasibility analysis, in environments of uncertainty. Rev cuba cienc informat [online]. 2016, vol.10, suppl.1, pp.117-132. ISSN 2227-1899.

ABSTRACT The software project feasibility analysis it is an essential process for developer’s entities, that it is complex, being software an intangible product. This process can be modeled as a multi expert and a multi criteria of making decisions is generally evaluated more than one project in uncertain environments. This paper proposes a method using fuzzy triangular numbers, to evaluate classical economic criteria such as NPV, IRR and PRI. It described the two phases of the method (initiation and evaluation), detailing the activities of each with its inputs and outputs. The experts are selected by analyzing the curricular synthesis of candidates. The evaluation criteria are defined using Focus Group. The proposal allows to treat the variations that may occur during the life cycle of the project in aspects such as: prices of direct and indirect materials, the stability of the workforce and other risks that impact the schedule, scope or quality of deliverables. As a final result the overall assessment of each project is obtained by order of feasibility considering the outcome of the criteria in three possible scenarios: one pessimistic, one more accurate and one optimistic. The latter is an important tool for identifying and managing project risks. Experimentally, the method was applied to three projects, evaluating three criteria and with the participation of three experts. The three projects were feasible, although with a different order of feasibility.

Palavras-chave : economic evaluation of projects; feasibility analysis; fuzzy triangular numbers; uncertainty.
