Özet:

 

Estimating the cost of software is a complex process for   almost all engineering companies. Uncertainties about development method,   design, estimation process, data, and processing affect the accuracy of   estimation. Underestimation results in fewer resources being committed than   the project really needs, an unrealistic schedule, and low quality outputs.   On the other hand, overestimation wastes resources and causes loss of   customer credit. Thus, choosing the appropriate cost estimation method is   crucial. Studies in the literature emphasize the importance of empirical,   analytical methods and expert judgement. Certain cost estimation techniques   have been widely studied in the literature. However, there are limited   studies using fuzzy approaches for software cost estimation. This paper   presents a hesitant fuzzy pairwise comparison (HFPC) used in the hesitant   fuzzy analytic hierarchy process for software cost estimation problems by   using expert judgement. For this purpose, first a number of criteria are   selected with the help of expert judgements from the Turkish banking sector   and information technology industry. Subsequently, the HFPC method is   presented to estimate the cost of software projects. In order to analyze the   efficiency of the proposed approach, it is applied to a software cost   estimation problem for a Turkish company. It is seen that the proposed   method provides efficient estimations due to low deviation between the real   effort and estimated cost. The results are also approved by experts working   in the relevant software company.
