This paper illustrates how Chittaro’s methods of modelling functions and goals can be applied to a reliability procedure known as Failure Modes and Effects. The use of functional models links structure to purpose and the central theme of this paper is to show how the design objectives of a system can be linked to the structure using functional models as an intermediary. The models are demonstra...

A methodology for the development of PM using the modern approaches of FMEA, root-cause analysis, and fault-tree analysis is presented. Applying PM leads to a cost reduction in maintenance and less overall energy expenditure. Implementation of PM is preferable to the present reactive maintenance procedures (still prevalent in Nigeria). 2006 Elsevier Ltd. All rights reserved.

After the 2008 Wall Street crash, it became clear to economists that financial systems, along with other social and economic systems, are not immune to being manipulated by small groups of players to their own advantage. Given this, two natural questions arise. For a particular policy design or proposed economic system, can such manipulation be foreseen in advance and possibly prevented? And ca...

The metro door system is one of the high failure rate subsystems of metro trains. The Failure Mode, Effects and Criticality Analysis (FMECA) method is applied to analyze the reliability of metro door system in this paper. Firstly, failure components of the door are statistically analyzed, and the major failure components are determined. Secondly, failures are classified according to their impac...

Reliability Centered Maintenance(RCM) is one of most widely used methods in the modern power system to schedule a maintenance cycle and determine the priority of inspection. In order to apply the RCM method to the Smart Grid, a precedence study for the new structure of rearranged system should be performed due to introduction of additional installation such as renewable and sustainable energy r...

Evaluating the sustainability risk level of public–private partnership (PPP) projects can reduce project risk incidents and achieve the sustainable development of the organization. However, the existing studies about PPP projects risk management mainly focus on exploring the impact of financial and revenue risks but ignore the sustainability risks, causing the concept of “sustainability” to be ...

This paper provides a method based on information theory for risk analysis and evaluation. A basic method to construction site risk evaluation by Shannon entropy is used. Safety and technical risk of the building construction process has been calculated by Shannon’s entropy which provides information of the system, of various kinds under uncertainties. The method has been applied to a case stud...

In the present paper, a complete process from reliability evaluation to design modification is proposed and also applied to a newly designed and manufactured Remotely Piloted Helicopter (RPH) by the authors. First of all, a description of all platform subsystems is presented. After that, function diagram and also product tree of the whole system is depicted for further analysis. Then, the relia...

risk management is one of the most important phases of project management and isthe most recently used by many researchers. in this paper, a fuzzy based method wasproposed which identifies different kinds of risks through the project life cycle.then, the project risk magnitude can be obtained in regards to five factors, namely“severity”, “occurrence”, and “not detection” which form fuzzy fmea a...
