Projects selection method based on the theory of possibility

Method for selecting projects based on the theory of possibilities is developed. The proposed approach reflects the situation when the dynamic nature of the project environment determines the impossibility of applying a deterministic or probabilistic approach. The method is based on the «project card», which, in the block form separated by content, unites the characteristics of the project, from which constraints and selection criteria of projects can be formed. This ensures the universality of the proposed approach. The type of fuzzy numbers used is trapezoidal to match the pessimistic, optimistic and most probable estimates. The developed selection procedure presupposes the «filtration» of projects by the given levels of reliability for the conditions under consideration. This reduces the volume of the information operated at subsequent stages. Also, within the framework of a scheme, the options for selecting projects according to one or more criteria are linked.
