In this work, the effectiveness of preventive maintenance scheduling (PMS) decisions was reported based on a techno-economic model that reflects cost objective function for ship maintenance activities. With a potential to impact on both transportation businesses and users of transportation services, the model provides an alternative to the combined classical literature problems of spare-parts i...

Production scheduling and preventive maintenance planning decisions are inter-dependent but most often made independently. Given that maintenance affects available production time and elapsed production time affects the probability of machine failure, this interdependency seems to be overlooked in the literature. We propose an integrated model that simultaneously determines production schedulin...

Industrial equipment requires maintenance to remain operational. The level of maintenance that is required, and how easily it can be executed, is affected by the characteristics of the equipment. Therefore, design decisions have a strong influence on the effectiveness and efficiency of the maintenance process. Ideally, the design of the equipment should be aligned with the design of the mainten...

Software developers make various decisions when implementing software. For instance, they decide on how to implement an algorithm most efficiently or in which way to process user input. When code is revisited during maintenance, the underlying decisions need to be understood and possibly adjusted to the current situation. Common documentation approaches like JavaDoc neither cover knowledge rela...

This paper examines, theoretically and empirically, the determinants of collective success in the maintenance of infrastructure projects. The empirical analysis employs primary data collected by the author on 132 community-maintained infrastructure projects in Northern Pakistan. Determinants are grouped into community-specific and project-specific factors, the latter identified using community ...

The present paper provides some ideas about how decisions concerning maintenance of timber bridges should be made in a rational way. First, a brief discussion is provided concerning the evolution of maintenance strategies in general and it is suggested that maintenance of timber bridges should follow a risk-based approach. Then the discussion moves on to the condition assessment of timber bridg...

The optimal maintenance scheduling of systems with degrading components is highly coupled with the design of the system and various uncertainties associated with the system, including the operating conditions, the interaction of different degradation profiles of various system components, and the ability to measure and predict degradation using prognostics and health management (PHM) technologi...

To optimize belt conveyor system (BCS) performance, a reasonable assessment of system reliability is desired and the decisions of how often to perform maintenance and the optimal occasion to replace a component are required. Intelligent belt conveyor monitoring (BCM) may automate the maintenance process. To realize such an intelligent system most of parameters of BCS have to be monitored. Too m...

Many maintenance decisions require the evaluation of alternative solutions in terms of complex maintenance criteria such as cost, repairability, reliability and availability requirements. Such problems can be formulated as multi-criteria decision making problems. The relative importance of maintenance criteria is difficult to be assessed, and therefore a sensitivity analysis becomes a necessity...

Condition monitoring allows maintenance actions to be based on changes of a trend of machine or process parameters. The identification, monitoring and fusion of data from key parameters can provide greater confidence in decisions. Data fusion is a relatively new term to the condition monitoring community. In defence and other applications the field is mature and has seen extensive application. ...
