4. 1. Structure and architectural hierarchy of DSS for locomotive crews

A distributed DSS for locomotive crews is a complex system with comprehensive interaction of the locomotive onboard systems located at a great distance; the quality of its organization determines efficiency of the system as a whole.

If P is the set of possible principles of constructing the system and its components; F is the set of interconnected functions performed by the system; A is the set of interconnected onboard locomotive systems, then, according to [15], the problem of synthesis of rational structure of a distributed DSS comes down to defining a set of principles of construction (p ϵ P), a set of functions performed by the system (f ϵ F (p)), a set of elements capable to implement the chosen principles and to perform functions (А ϵ А). It is also necessary to find the optimum display of elements of the set f on the elements of set А. When selecting the option of the structure of a complex system, there are two possible types of display f → А
