The paper develops a goal programming-based multi-criteria methodology, for assessing different machine learning (ML) regression models under accuracy and time efficiency criteria. developed methodology provides users with high flexibility in the as it allows fast computationally efficient sensitivity analysis of significance weights well threshold values. Four were assessed, namely decision tr...

In a deregulated power industry, a maintenance strategy is of critical importance for transmission systems composed of aging components. Such a strategy can provide significant cost savings by optimizing maintenance decisions for power system operation. This paper presents a Reliability-Centered Maintenance (RCM) model for developing a maintenance strategy in a transmission system. This model i...

Opportunistic maintenance has been an essential part of all systems-maintenance, implicitly if not explicitly. However, as systems become more expensive and complex, the decisions involving opportunistic maintenance activities become more complicated. In this paper, we discuss a few issues that arise while carrying out the opportunistic maintenance, and try to resolve them with the help of a po...

Detailed maintenance planning under uncertainty is one of the most important topics in military research and practice. As one of the fastest ways to recover failed weapon systems, cannibalization operations are commonly applied by maintenance personnel. Due to additional complexities introduced by these operations, detailed maintenance decision making with cannibalization was rarely studied in ...

Over the last decade, many large organizations have been shifting from developing their own information system (IS) to licensing and installing large software packages known as enterprise resource planning (ERP) systems. These organizations now face the challenge of maintaining these costly systems and many are about to make their first upgrade decisions. The study reported herein aims to addre...

Making decisions on building maintenance policies is an important topic in facility management. To evaluate different maintenance policies and make rational selection, both performance and maintenance cost of building components need to be of concern. For roofing sytem Markov Chain model has been developed to simulate the stochastic degrading process to evaluate the life cycle perfornance and c...

Assessing the life-cycle impacts of operations and maintenance decisions made for new or aging systems requires an accurate ability to measure and respond to uncertainty. Maintenance and parts requirements forecasts for fielded military systems are traditionally performed through historical repair and supply demand models. These models work well once several years of steady state weapon system ...
