 Title: Systems Analysis: the Structure-and-Purpose Approach Based on Logic-linguistic Formalisation Authors: Lukiyanova, Lyudmila Keywords: Industrial Organizing SystemProblem SituationSystems AnalysisQuality of Systems AnalysisPurpose Structures CorrectnessStructure and Purpose ApproachSituations ControlLogic and Linguistic SimulationAnalytic Evaluation Issue Date: 2003 Publisher: Institute of Information Theories and Applications FOI ITHEA 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.
