目前电梯的检验质量受到了社会的广泛关注,检验报告抽查是对电梯检验质量进行控制的重要环节。为解决检验报告抽查的科学性和精确性,本文尝试将统计学上的分层抽样理论引入电梯检验报告抽查中,本文论述了分层抽样的基本理论及其用于电梯检验报告抽查的可行性,介绍了分层抽样应用于电梯检验报告抽查的实施步骤,并进行了实例计算。
At present, the inspection quality of the elevator has been widely concerned by the society. The spot check of the inspection report is an important part of controlling the quality of the elevator inspection. In order to solve the scientificity and accuracy of random inspection report, this paper attempts to introduce the statistical theory of stratified sampling into the inspection of elevator inspection reports. This paper discusses the basic theory of stratified sampling and its feasibility for spot check of elevator inspection reports , Introduced the stratified sampling applied to the elevator inspection report spot check implementation steps, and carried out an example calculation.
