Equipment system testability evaluation calculating method

Abstract

The invention discloses an equipment system testability evaluation calculating method which comprises steps as follows: step A, working principles and characteristics of an equipment system are analyzed, the use demand and testability demand of the equipment system are summarized, a diagnostic scheme and testability requirements are determined, and testability design criteria are established; step B, a comprehensive weighting influence set is established with a comprehensive weighting method according to the influence degree of the testability design criteria relative to the testability requirement; and step C, conditions, according with the testability design criteria, of sub-objects of the equipment system are analyzed with a top-down method, and a testability value is obtained in combination of the comprehensive weighting influence set, so that the testability design of the equipment system are checked and evaluated. According to the equipment system testability evaluation calculating method, the diagnostic scheme and the testability requirements are taken as main evaluation factors, the equipment system is subjected to objective and effective analysis in combination of other requirements of equipment system design and conventional resources, and the method is widely applied in the development process and design identification of the equipment system.

Description

technical field [0001] The present invention belongs to the technical field of testability engineering, and specifically belongs to the application of testability analysis and evaluation technology in equipment systems, including determining diagnostic schemes and testability requirements, establishing testability design criteria, conducting design criterion conformity analysis on equipment systems, and completing equipment system testing. System testability evaluation. Background technique [0002] As a design feature of equipment, testability is as important as reliability, maintainability, and supportability, and is an important part of equipment quality characteristics. As an important link between equipment reliability design and equipment maintenance support design, testability is an important intermediate link to ensure that equipment combat readiness, mission success and safety requirements are met. Through good testable design, the combat readiness, mission success...
