基于萤火虫算法的MEWMA控制图的经济性统计性设计

Economic-Statistical Design of MEWMA Control Chart Based on Firefly Algorithm

MEWMA控制图是检测多个相关质量特性过程下的微小偏差的常用工具。如何在保证控制图的经济性能的情况下提高控制图的统计性能来进行设计,是增加控制图实用性的关键。提出了一种MEWMA控制图的经济性统计性设计模型。MEWMA控制图的经济性统计性模型的设计问题通过萤火虫算法解决。经济性设计与经济性统计性设计之间的比较研究表明,经济性统计性设计的统计性能更好,成本增加近乎可忽略不计。

This paper proposes an economic-statistical design model of MEWMA control chart.The design problem of the economic-statistical model of the MEWMA control chart is solved by the firefly algorithm.A comparative study between the economic model and the economic-statistical model shows that the statistical performance of economic-statistical design is better,and the cost increase is almost negligible.
