Problems solved by technology

[0005] At present, the risk management and control of heavy-duty machine tool research and development process is basically carried out by manual organization staged review, the risk evaluation index system, scoring measurement standard, evaluation method, risk rating and other standards are missing, the review process is relatively subjective, and the data of the project research and development process is seriously related. Out of touch, the evaluation results are lagging and inaccurate, which can no longer meet the needs of quality risk management and control in the complex project development process under the condition of informatization

Abstract

The invention discloses an automatic evaluation and control method for a quality risk in a research and development process of a power tool. The method comprises the steps that an evaluation index system reflecting the quality risk in the research and development process of the power tool is constructed; real-time collection of online data is realized through a data interface mounting and power tool enterprise research and development process informatization system; a fuzzy complementary judgment matrix of a machine tool project is transformed into a fuzzy consistent judgment matrix; accordingto the actual research and development project quality risk evaluation demand, needed indexes are configured in a custom mode from the index system, and a quality risk evaluation factor library is formed; a multi-expert fuzzy analytic hierarchy process is utilized to perform evaluation metering design and weight calculation on the quality risk evaluation factor library; research and development quality risk data and a corresponding grade are obtained through calculation according to the quality risk evaluation factor library and a weight value in combination with the real-time online data; and a certain parameter of the machine tool is adjusted according to an evaluation value to improve the overall quality of the machine tool.
