Handbook of Reliability, Availability, Maintainability and Safety in Engineering Design - Part 29 studies the combination of various methods of designing for reliability, availability, maintainability and safety, as well as the latest techniques in probability and possibility modelling, mathematical algorithmic modelling, evolutionary algorithmic modelling, symbolic logic modelling, artificial intelligence modelling, and object-oriented computer modelling, in a logically structured approach to determining the integrity of engineering design. . | Application Modelling of Reliability and Performance in Engineering Design 263 Fig. Hazards criticality analysis assembly condition portion of the FMEA results are very similar at both levels. Thus in a hazards criticality analysis of the condition of selected components for inclusion in a design the following component condition data illustrated in Fig. are defined Failure description Failure effects Failure consequences Failure causes. Figure illustrates a hazards criticality analysis of a common functional failure fails to open of a HIPS control valve. The condition worksheet in hazards criticality analysis is similar to the specifications worksheet of selected equipment for consideration during the detail design phase of the engineering design process in that it automatically integrates matched information pertaining to the equipment condition and criticality as illustrated in Fig. with the necessary installation maintenance information concerning the following Information from the equipment diagnostics worksheet relating to failure description failure effects failure consequences and failure causes 264 3 Reliability and Performance in Engineering Design Fig. Hazards criticality analysis component condition Information relating to equipment criticality Information relating to the necessary warranty maintenance strategy Information relating to the estimated required maintenance costs Information relating to the design s installation logistical support The hazards criticality analysis condition spreadsheet is a layout of selected components based on the outcome of the condition worksheet of selected equipment for consideration during the detail design phase of the engineering design process. The condition spreadsheet Fig. is automatically generated and serves as a FMEA pro-forma for electronically automated design reviews. The spreadsheet is variable in that the data columns can be adjusted or hidden but not deleted. These data .
