Estimation method and system for reducing full-life-cycle cost of radar

Abstract

The invention discloses an estimation method and system for reducing the full-life-cycle cost of a radar, and relates to the field of radar cost management. The method comprises the following steps: establishing a hierarchical structure of the radar full-life-cycle cost according to a plurality of influence factors of the radar full-life-cycle cost and included cost items, and constructing a judgment matrix among structural layers in the hierarchical structure, calculating each feature vector of each judgment matrix, carrying out hierarchical single sorting and hierarchical total sorting, carrying out consistency check on results of each hierarchical single sorting and hierarchical total sorting, and if the check is passed, obtaining the judgment matrix; if not, taking the hierarchical total sorting weight obtained according to the hierarchical structure as the weight ratio of various measures for reducing the full-life-cycle cost of the radar, and performing quantitative analysis on cost management through an analytic hierarchy structure, thereby improving the availability of radar equipment and reducing the full-life-cycle cost of the radar.

Description

technical field [0001] The present invention relates to the field of radar cost management, in particular to an estimation method and system for reducing the cost of the whole life cycle of a radar. Background technique [0002] As an important equipment in the field of military and civilian electronics, radar systems are widely used in guidance, warning, space target monitoring, imaging, meteorological monitoring and other occasions. In recent years, with the development of radar products, the performance of radar has been continuously improved, and the radar system has become increasingly sophisticated, complex and huge. Therefore, when purchasing radars, users often take radar life cycle cost management as an important indicator into the purchasing requirements. [0003] Radar life cycle cost management refers to planning, organizing, commanding, coordinating and controlling activities related to the radar life cycle cost with the goal of minimizing the life cycle cost o...

Problems solved by technology

However, in terms of radar life cycle cost management at the present stage, it is common to place more emphasis on purchase costs and less on use and support costs. The management system and regulations are not yet perfect, and there is a lack of unified planning and supervision and management of radar life cycle costs. There is a lack of effective information communication channels between the various stages of the radar life cycle

Usually, the purchase cost and service guarantee cost of the radar system show a trade-off relationship, and the purchaser often ignores the reliability, maintainability and other performance indicators of the equipment in order to save the purchase cost, which will inevitably lead to an increase in the use and maintenance cost
