According to a report of reliability engineering assignment published by American Reliability Analysis Center in 1995, failure reporting, analysis and corrective action system(FRACAS) is at the top of the sort order in many reliability engineering assignments, so the importance of FRACAS is internationally recognized. The necessity and importance of implemented 3F (FMEA, FTA, FRACAS) is also definitely presented in the reliability implementation brief of our industries and departments.The FRACAS system put the information together which is about designing, supplying, producing, quality, selling and repairing. Stat. by computer, evaluate the reliability of products, draw out the failure rate curve, analyze failure reasons, find out the weakness of product reliability, work out problem, and then improve product quality by ameliorating reliability designing. This is a“closed loop”with implementing zeroing measures in Management.Aiming at satisfiding the business enterprises’need, combined the army mark GJB841’s design to FRACAS system norm, introduced the total project of the measure system which analysis and rectify of failure information, make sure the main contents of input and output’s important information.Through tailor a workflow,making the failure information analysis and rectify measure system analyze and rectify in planning and organizing ways, ensuring the veracity and validityof the analytical reasons of the failure,and preventing a project form build up at discretion.The existing function of FRACAS software is more perfect abroad, but,some disadvantages decide that it can’t fit for our country well.For example,limited use range,poor functional agility,higher price,and also need to enhance the statistic function.This articale developed a kind of FRACAS system based on independent intellectual property rights.It can fit for our middle-minityped corporation structures.In order to enhance the system function, through custom-built design, failure mode, failure level, workflow etc, all are defined by customers.In order to enhance the statistic function,this system also provide some interfaces to FMEA,FTA,aptitude analysis module,MATLAB and NN module.In this dissertation, introducing the correlative technology of reliability and database designment, using ASP.NET application which the mode is three floors system to realize networking. Finally through a system function, showing the whole process of break down information analysis and rectify, to change the shortage which the traditional management system don’t form in business enterprise.
