The principles for setting up an index system have been analyzed and the index system has been set up according to projects of construction. Models for multi-level fuzzy comprehensive appraisal have been offered and relative calculation steps have been given according to project instances.展开更多

Fatigue involvements in engineering systems are complex requiring indepth analysis and optimization of the governing phenomena. The pervasive demand for suitable solutions to this circumstance has been the greatest problem faced by the systems engineers in the quest for delivering sustainable infrastructural development. Consequently, the removal of interdisciplinary boundaries and merge of design platforms pose a great challenge for an unprepared project engineering and technology community. It is imperative to understand the mechanisms promoting fatigue occurrences for a complete model conceptualisation and analysis improvement. In this paper, the duo evaluation--linear and effective crack length measurements are clearly shown to beacon the fatigue investigation for modem project engineering and technology. The paper has also examined the airfield pavement where this concept could be very useful. Such breakthrough would require accurate fatigue simulation and modelling platforms for inbuilt reliability and prudent resources management. Amongst the benefits of the fatigue analysis is the provision of an enabling environment for the sustainable management of engineering and technology projects.展开更多
