Research On The Design Quality Comprehensive Evaluation System Of The Multi-funtion Packaging Machine

Packaging machinery as one of the top ten industries in industrial machinery industry, has an important role in production. Product design quality refers to the degree of the product meet the expectation, and 75 percent of the product quality problems comes from the product design quality. In order to improve the design quality level of packaging machinery in our country, construction the design quality comprehensive evaluation system is built to the multi-function packaging mechanism, and the appropriate evaluation method is selected to complete the design quality comprehensive evaluation, then according to the process, a system is developed completely, realize the man-machine interactive evaluation.The focus of the article has the following four points:1、Analysis of the multi-function packaging machine quality characteristics and creative proposed oriented multi-function packaging machine design quality comprehensive evaluation system; through research and summary on the evaluation methods, selecting the combination of AHP and entropy method to evaluate the comprehensive evaluation of design quality, and improve the effectiveness of index weight, and enhance the reliability of the results.2、On the basis of the evaluation theory research, the system has carried on the demand analysis and system performance analysis aiming at evaluation system. Secondly, according to the requirements analysis, the general layout and concept design is designed to the function of the system. And then the detailed design system is designed.3、With the bases of completing the detailed design of the system, according to the function of the system, tables are determined by the function, then the structure of each table is determined according to the requirement.4、With the tool of the web programming, PHP programming language and ThinkPHP framework, according to the detailed design of the system, a multi-functional packaging machine design quality evaluation system is designed. Finally, the reliability of the system texted by a case is verified by MATLAB, which indicates that the system has important application value in the comprehensive evaluation of the design quality of the multi-function packaging machine.
