The Research on Analysis of Effectiveness and Cost in Application of Turboshaft Engine Demonstration and Decision

摘要

At present, the scientific and detailed process is lacking on the demonstration of turboshaft engine, and the demonstration stage is very important for the development of new pattern turboshaft engine. Practices show that it has made up 80 percent of the life cycle cost at the end of demonstration, and the cost of demonstration is only 3 percent of the life cycle cost. The analysis of effectiveness and cost is decision-making method about handling complex multiple factors, optimizing multi-objective and multi-scheme, it can effectively regulate the life cycle cost by applying the analysis of effectiveness and cost in demonstration. This paper makes extensively study on the demonstration process, which reveals the effects and methods on demonstration and decision-making process by the analysis of effectiveness and cost. These researches will be of great importance in enhancing the scientific validity of the demonstration of turboshaft engine.
