An Efficiency of Technologies and a Strategy for Synthesis of Integrated Life Support System Structure 2000-01-2396

The research conducted at NIICHIMMASH for the past several years in the area of Integrated Life Support System (ILSS) strategy development for technology efficiency analysis and system structure synthesis is reviewed in this paper.This study proposes an generalized efficiency model for ILSS development, which includes global, thermodynamic and local quantitative and qualitative factors.The research resulted in a strategy for the synthesis of ILSS structure based on evolutionary and integral- hypothhetical approaches. This strategy allows development of new system configurations, evaluation of existing ILSS effectiveness and considers decision marker's (DM) preferences.Uncertainty in the initial information about properties of the system or technology has a big influence on DM making decisions about future system appearance. Fuzzy set theory is used to define the uncertainty in the initial information. The approach is based on application of membership function to set tolerances on criteria values.
