We consider in this article three approaches to estimating the cost of software: income, cost and comparative. The advantages and disadvantages each of them are analyzed. Comparative approach is considered in details and a set of the problems limiting its use in the assessment of the cost of the software is identified. The main problem is a lack of flexible metrics on which it would be possible to carry out comparison of all types of software. The authors consider that the solution of these tasks is capable to solve these problems. The first task involves the development of graph-software models – mathematical description of software that contains information about its properties, the components and the internal connections between them. The second task is development of mathematical model of software comparison. Software graph-model are proposed to use as objects of comparison. Within this step the concept «software equivalence» is entered. The task of this characteristic – the description of similarity of carried-out functions, the result of work and the ways of result achievement. The third objective is to develop software that implements the work with the graph models of software and software comparison models. It was noted that the relevance of the development of new techniques within the comparative method in cost assessment of software and the ability to adapt them for use in the cost assessment of other types of property, since at flexible mathematical models are put as the base of techniques.
