Comprehensive Quality Evaluation System for Manufacturing Enterprises of Large Piston Compressors

Piston compressors are necessary dynamic equipment in chemical engineering and petrochemical industry. Establishment of a quality evaluation system for Chinese manufacturing enterprises of large piston compressors is important for the proper evaluation of production quality. The evaluation system can serve both government decision-making and user selection-making. Furthermore, the quality evaluation system is beneficial for identifying production bottleneck and improving production quality. A hierarchical analytic process is adopted in this paper to establish a comprehensive quality evaluation system. The system characteristics can be summarized into three levels, two main lines, and one correction. The first level consists of two main routes, external effects and intrinsic effects. The second level includes 6 external factors and 7 intrinsic factors. The third level is composed of 81 elements. In addition, the product accident history is introduced at the first level as a correction item. The evaluation system was implemented using B/S architecture and the standard SSM framework with MVC design pattern.
