The most obvious considerations that affect an organization's choice of security technologies are the threats the organization considers significant and the costeffectiveness of various security technologies against those threats. In practice, however, the choice is also strongly driven by less tangible, more nontechnical, considerations such as ease of implementation and maintenance, fit with ...

With the evolution of technology, the maintenance of sophisticated systems is of concern for system engineers and system designers. The maintenance cost of the system depends in general on the replacement and repair policies. The system replacement may be in a strictly periodic fashion or on a random basis depending upon the maintenance policy. At failure, the repair of the system may be perfor...

The present paper deals with development of a simulation model for the performance evaluation of feed water system of a thermal power plant using Markov Birth-Death process and probabilistic approach. In present paper, the feed water system consists of four subsystems. After drawing transition diagram for feed water system, differential equations are developed and then solved recursively using ...

Software maintenance phase is started once a software project has been developed and delivered. After that, any modification to it corresponds to maintenance. Software maintenance involves modifications to keep a software project usable in a changed or a changing environment, to correct discovered faults, and modifications, and to improve performance or maintainability. Software maintenance and...

Purpose – The purpose of this paper is to present a framework for environmental management system (EMS) adoption which can be used by managers to enable them to achieve a faster, smoother, effective and sustainable EMS implementation. This is termed by the authors as “successful” EMS implementation. Design/methodology/approach – The framework presented is based on an extensive field study condu...

Engineering asset management (EAM) is a broad discipline with distributed functions and services. When engineering assets are capital intensive, management requires specialized expertise for diagnosis, prognosis, maintenance and repairs. The current practice of EAM relies on self maintained experiential rules with coordinated collaboration and outsourcing for maintenance and repairs. In order t...

ABSTRACT: Most pavement maintenance management systems tend to be either non-analytical databases or statistical correlation models. However, pavement maintenance is part of a complex system comprising the road pavement, the environment, diverse users, the maintenance authority and Local/State/Federal Governments. This system has significant feedbacks, making it a suitable field for system dyna...
