Key technology identification method and identification system for aero-engine development

Abstract

The invention relates to the technical field of aero-engine risk identification, and specifically provides a key technology identification method and identification system for aero-engine development.The key technology identification method and identification system for aero-engine development can tease out all the technologies related to the stage of aero-engine development by constructing a technology breakdown structure (TBS) of projects, and can realize complete and effective identification of the key technologies of the projects through identification criterions of a series of key technologies, and through combination with definition of the technology application environment. The key technology identification method and identification system for aero-engine development can completelyand effectively identify the key technologies for project development by means of the mode of identifying key technologies on the basis of the technology breakdown structure, thus effectively solvingthe problems that a current key technology identification method is not complete in identification of key technologies and is not reasonable in identification of key technologies and the like.

Description

technical field [0001] The invention relates to the technical field of aero-engine risk identification, in particular to a key technology identification method and an identification system for aero-engine development. Background technique [0002] As a comprehensive and integrated system with highly complex technology, the development of aero-engines has great risks. The low maturity of key technologies is the main source of project technical risks, which may lead to project schedule lag, increased development costs, and even project failure. In order to meet the needs of engine stakeholders and improve the performance and reliability of aero-engine products, some new technologies and methods need to be applied as key technologies in the project. [0003] At present, the identification of key technologies of domestic aero-engine development projects is mainly carried out by the heads of various departments of the project to convene expert discussions. Experts use brainstormi...

Problems solved by technology

[0004] 1. The entire identification process of this method is greatly influenced by human beings, and there is no reasonable guidance method on whether the identified key technologies are accurate, whether there are omissions in key technologies, and whether the main technical risks of the project can be covered, which leads to the possibility of identifying key technologies of the project. There are problems such as incomplete identification of key technologies and unreasonable identification of key technologies, which affect the management and control of technical risks of the project, thereby affecting the quality, cost, and cycle of product development;

[0005] 2. Using this method to identify the key technologies of the project requires the project R&D team to invest a large number of professional designers and spend a long time in the discussion to identify relatively complete key technologies. This method requires high labor costs. low efficiency
