The aim of this paper is to develop an innovative Lean Maintenance model in order to optimize the process flow and reduce or eliminate scraps and work-in-progress (WIP) in a manufacturing context. To achieve these objectives has been formulated a new method, called Lean Root Cause & Defect Analysis (LRCDA), which merges the process steps of the existing Root Cause & Failure Analysis (RCFA) tech...

Generation or transmission maintenance scheduling packages provide preventive or corrective maintenance scheduling over a certain period in order to minimize system costs while fulfilling relative requirements. In advanced power systems inclusion of network constraints and increasing rate of electricity demand may result in higher number of generators and transmission lines and hence lower syst...

Preventive maintenance actions over the warranty period have an impact on the warranty servicing cost to the manufacturer and the cost to the buyer of fixing failures over the life of the product after the warranty expires. However, preventive maintenance costs money and is worthwhile only when these costs exceed the reduction in other costs. The paper deals with a model to determine when preve...

The Circuit Breaker (CB) is one of the most important equipment in power systems. CB must operate reliably to protect power systems as well as to perform tasks such as load disconnection, normal interruption, and fault current interruption. Therefore, the reliable operation of CB can affect the security and stability of power network. In this paper, effects of Condition Monitoring (CM) of CB on...

Certain mechanical shortcomings in engines cannot be ascribed to errors in design or defects in construction. They are due to the fact that it is impossible to design and construct engines in a way that completely eliminates friction between its parts. Friction causes wear and tear that is proportional to the amount of use. Likewise, when it comes to software one should not expect it to behave ...

Many process models have been hitherto suggested. Very few of them, however, deal with the most utilised process today – the maintenance process. In this paper, we present and motivate the “Corrective Maintenance Maturity Model” (CM 3 ) a process model entirely dedicated to only software maintenance. .

This chapter presents the process of upfront corrective maintenance at the front-end support level. The chapter is logically divided into two parts. The first part introduces the domain of the upfront corrective maintenance process, and presents its current status practised in the industry. It first describes the process, places it within a global virtual IT enterprise and explains its role wit...

Wind power is one of the most important sources renewable energy available today. A large part cost wind due to maintaining equipment. When a turbine component fails function, it might need be replaced under circumstances that are less than ideal. This known as corrective maintenance. To minimize unnecessary costs, more active maintenance policy based on life expectancy key components preferred...
