Abstract:
Systems analysis (SA) is widely used in complex and vague problem solving. Initial stages of SA
are analysis of problems and purposes to obtain problems/purposes of smaller complexity and vagueness that
are combined into hierarchical structures of problems(SP)/purposes(PS). Managers have to be sure the PS
and the purpose realizing system (PRS) that can achieve the PS-purposes are adequate to the problem to be
solved. However, usually SP/PS are not substantiated well enough, because their development is based on a
collective expertise in which logic of natural language and expert estimation methods are used. That is why
scientific foundations of SA are not supposed to have been completely formed. The structure-and-purpose
approach to SA based on a logic-and-linguistic simulation of problems/purposes analysis is a step towards
formalization of the initial stages of SA to improve adequacy of their results, and also towards increasing
quality of SA as a whole. Managers of industrial organizing systems using the approach eliminate logical
errors in SP/PS at early stages of planning and so they will be able to find better decisions of complex and
vague problems.
