The paper describes a systematic approach to support the redesign process. Redesign is the adaptation of a technical system in order to meet new specifications. The approach presented is based on techniques developed in model-based diagnosis research. The essence of the approach is to find the part of the system which causes the discrepancy between a formal specification of the system to be des...

The satisfying of human needs through designing technical objects requires the compromisation and settling of various conflicting criteria at different stages of the engineering design process. The need for back and forth adjustment of design specifications, concept finding, and design embodiment can be considered to be carried out in a telescopic review fashion. The present study is concerned ...

Dependability analyses in the design phase are common IEC 60300 standards to assess reliability, risk, maintainability, and maintenance supportability of specific physical assets. Reliability risk assessment uses well-known methods such as failure modes, effects, criticality analysis (FMECA), fault tree (FTA), event (ETA)to identify critical components modes based on rate, severity, detectabili...

Specifications have a large impact upon capital and operating costs because they are formulated early in the design process. Models of the specification process have been developed for the automotive industry. These models have many shortcomings and have limited application in other sectors. This paper examines the development and use of specifications relating to customised plant for the elect...
