The present work adopted Reliability Centered Maintenance (RCM) methodology to evaluate marginal oilfield Early Production Facility (EPF) system properly understand its functional failures and develop an efficient maintenance strategy for the system. outcome of RCM conducted a typical EPF within Niger Delta zone Nigeria provides indication equipment whose failure can significantly affect operat...

This paper focuses on the reliability estimation of equipment based on degradation data and on a economic maintenance model that takes into account corrective and preventive replacements as well as inspections costs. We generate the degradation data with a semi-Markov model with 3 states. Each state has a constant degradation rate that contributes to the damage. The degradation paths are simula...

We study the problem of containing spreading processes in arbitrary directed networks by distributing protection resources throughout the nodes of the network. We consider two types of protection resources are available: (i) Preventive resources able to defend nodes against the spreading (such as vaccines in a viral infection process), and (ii) corrective resources able to neutralize the spread...

In this paper, the reliability allocation and index of overall cost rotary ultrasonic vibration-assisted EDM machine tool were studied. The failure rate each module can be accurately predicted by maximum entropy ordered weighted average algorithm so that corrected maintenance predicted. And effective control preventive costs achieved selecting best times under premise reliability. corrective re...

We establish the context of maintenance outsourcing of mission critical applications by Fortune 500 organizations. We present the results of empirical studies that were conducted at Syntel, a NASDAQ listed application management and e-business solutions company, on 46 software maintenance projects that belonged to various lines of business on the IBM mainframe platform using an automated data c...
