Master's Thesis from the year 2003 in the subject Engineering - Safety Engineering, University of Warwick (WMG), course: QR program, language: English, abstract: Testing is an important issue in any development programme, because it becomes more important and a significant component of the overall development effort when the development risks are high. Designs are not always perfect and designers usually are not able to analyse all the likely causes of failure of their designs in service, accordingly testing is necessary to determine the reliability of the design, but what kind of tests should be applied? In fact any kind of test can be considered as a part of an integrated test programme, that should include: Functional performance testing, Environmental testing, Reliability and durability testing and Safety testing. The test programme should be managed and planned correctly into the phases of concept creation, design, development, manufacturing and service. where, the implemented tests during each phase, are different from another phases. Testing especially during the development phase is nearly expensive and uncertain in relation to time and other resources required. The effective selection of testing programs (and the incurred costs due to ineffective selection of testing programs) will be noticeable in the future, so a long- term view is significant. In fact all the test aspects: what to test, how to test, test plans, test implementation, link design analysis tools to test program. requires sufficient expertise in this field to achieve the goals of the test. Testing regimes at some companies rely on expert testing in specific applications to establish an appropriate testing program and then they carry it out. The main objectives of this project; is to develop an expert system that is able to provide: 1. A list of most appropriate tests for a system /equipment under consideration. 2. Guidelines for an optimal test plan and explaining the way to implement the test. Application of expert systems in the field of testing programs will help to design a tool that allows the automatic selection of the most appropriate tests for a system /equipment under consideration. Where the required knowledge can be accessed quickly and easily by managers that will aid the quality of decision-making. Usage environment, test goals, design analysis tools (FMEA, FTA and ET) and some information from literature will be combined to build a decision tool for designing a robust test process. It is also intended that physics of failure principles will be used to aid the identification of failure modes, failure mechanisms and stressors.
