Study on an Evaluation Method of Data Center Construction Quality Based on Three-View Model

There are two kinds of bid evaluation methods in China, which are the lowest bid price method and the comprehensive evaluation method. They have their own advantages and disadvantages, and they can’t replace each other. Especially, the applicable scope of comprehensive evaluation method is wide. Quantifying the technical bid and commercial bid weighted, calculating for each bid comprehensive evaluating price or comprehensive evaluation points, and then selecting a high comprehensive quality unit. The paper aims at the particularity of comprehensive evaluation method. Then to study the content of the construction quality management system, the indicators and criteria, which guarantees the quality of the project.

Hierarchy Process

In this paper, a new comprehensive assessment method of pile construction quality based on analytic hierarchy process is proposed considering that the current specification is uncertain about quality assessment. This method establishes the comprehensive assessment index system of pile construction quality taking account of the influence of the pile velocity, pile length, geological condition, bridge importance level, pile defects and other parameters on pile construction quality assessment. It constructs pile construction quality assessment model through determining the weight of each index based on analytic hierarchy process to improve the evaluation method of pile construction quality. The good results achieved in practical engineering demonstrate that the proposed method possesses favorable accuracy.

Meaningful Improvement

Traditional datacenter temperature monitoring method is to install some temperature sensors which are unable to cover all areas completely, so there are some problems about local hot spot. The method is aiming to find out the position of potential hazard which may exist in the data center on the basis of data center thermal environment evaluation method and characteristics of air distribution. By applying this method into the wireless sensor network monitoring system, it brings a meaningful improvement of the monitoring system.
