Modeling the problem of transport network synthesis under conditions of uncertain initial information

This paper dwells upon the problem of synthesising structures under indefiniteness. Herein is proposed a classification of initial information uncertainty types that influence the parameters of transport networks. It is shown that different types of uncertainties can be narrowed down to two types, internal and external. The article presents formal models of problems reflecting the said types of uncertainties and different ways of describing them by means of the interval analysis and fuzzy sets. Schemes for solving the problems posed are given based on the decomposition approach. (C) 2015 The Authors. Published by Elsevier Ltd.
