全程全网性是铁路电务部门最重要的特点。全程全网的质量管理是电务部门全面质量管理的核心。本文分析了全程全网的特点,闸述了其质量特性,即可靠、安全、便利、及时、经济,并提出了相应的计量指标。全程全网质量评定的对象必须具有可比性,应当排除客观因素的影响。本文论述了用“选控值”进行质量评定的理论依据及方法。讨论了全程全网控制图的原理及制作、管理方法,阐述了用控制图进行质量诊断的基本思想。文中用具体实例进行了分析,提供了C_(cs)图的第一个实例,并探讨了全程全网质量保征体系及质量管理经济效益的评价方法。这些原则和方法对整个运输网的质量管理有参考价值。
The whole network is the most important feature of the railway power sector. The entire network of quality management is the core of the total quality management of the electrical department. This paper analyzes the characteristics of the whole network throughout the country, states its quality characteristics, that is reliable, safe, convenient, timely and economical, and puts forward the corresponding measurement index. The whole network of quality assessment of the object must be comparable, objective factors should be ruled out. This article discusses the theoretical basis and method of quality evaluation with “control value”. The principle of the whole network control chart and the methods of making and managing are discussed. The basic idea of quality control using the chart is expounded. The article uses the concrete example to carry on the analysis, has provided the first example of the C_ (cs) chart, and explored the entire network entire quality guarantee system and the quality management economic benefit appraisal method. These principles and methods for the entire transport network quality management has reference value.
