Highways and in particular their pavements are the fundamental components of the road network. They require continuous maintenance since they deteriorate due to changing traffic and environmental conditions. Monitoring methods and efficient pavement management systems are needed for optimizing maintenance operations. Pavement performance prediction models are useful tools for determining the op...
This paper presents some developed and implemented theory which can be applied to optimization of condition-based maintenance decisions within the context of physical asset management. We examine a replacement problem for a system subject to stochastic deterioration. In particular, the analysis of a preventive replacement policy of the control-limit type for a system subject to inspections at d...
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...
Design for maintenance and maintenance operations become increasingly important in recent years. In the capital-intensive industry, maintenance expenditures can add up to several times the initial investment. In order to be competitive in their business, owners and users of these capital goods have to take into account the total life cycle cost at investment (the lifespan of a train is about 30...
Title of Document: ELECTRONIC PROGNOSTICS AND HEALTH MANAGEMENT: A RETURN ON INVESTMENT ANALYSIS Kiri Feldman, Master of Science, 2008 Directed By: Dr. Peter Sandborn, Associate Professor, Department of Mechanical Engineering Prognostics and Health Management (PHM) provides the potential to lower sustainment costs, to improve maintenance decision-making, and to provide product usage feedback in...
Risk assessment for power transformer is an important means to guide the condition based maintenance of transformer and enhance the reliability of power system operation, but also to strengthen the power transformer to provide an important basis for quality control. In this paper, an index system for comprehensive evaluation of transformer is put forward and a risk assessment model for power tr...
This paper presents an object model for maintenance management of roofing systems as a case study to demonstrate the applicability of a proposed generic framework for integrating the maintenance management of built-assets. The model builds upon the Industry Foundation Classes (IFCs) (Releases 2.0 and 2.x) to define object requirements and relationships for the exchange and sharing of maintenanc...
The management of low-volume roads has transitioned from focusing on maintenance designed to protect a capital investment in road infrastructure to also include environmental effects. In this study, two models using mathematical programming are applied to schedule forest road maintenance and upgrade activities involving non-monetary benefits. Model I uses a linear objective function formulation...
