User costs related to maintenance operations represent a considerable amount of public expense in the United States. They are in the forms of extra fuel consumption, higher vehicular operating and maintenance costs, and additional travel time. As the demand for road maintenance keeps increasing, there is a tremendous need to reduce the user costs by introducing new technologies. Automating road...

Inearly 1981 the Howard County Department of Recreation and Parks, through its Bureau of Parks, began to identify a potential problem in operations. Developed park acreage was expanding so rapidly that the staff envisioned a time in the near future when the overall maintenance requirements would vastly outstrip the available operatingbudget dollars. The rate of development between 1975 and 1987...

Wiki systems have developed over the past years as lightweight, community-editable, web-based hypertext systems. With the emergence of Semantic Wikis, these collections of interlinked documents have also gained a dual role as adhoc RDF [8] graphs. However, their roots lie at the limited hypertext capabilities of the World Wide Web [1]: embedded links, without support for composite objects or tr...

The cost of software maintenance is rising dramatically and it has been estimated in [1] that nowadays software maintenance accounts for more than 90% of the total cost of software, whereas it was around 50% a couple of decades ago. There are several reasons for this. We can see that software systems become hard to maintain over time, while every day more and more software is being produced. Do...

The potential benefits of optimal service scheduling for cleaning heat exchangers based on minimizing operating costs are explored. A demonstration is performed on a simulated 20 ton air-to-air vapor compression air conditioner. The costs of regular service schedules (indicative of current practice), minimal schedules needed to maintain comfort, and the optimal schedules are compared. Generally...

Purpose – The purpose of this paper is to determine the fundamental factors influencing maintenance costs of logistic buildings and to provide benchmark indications for designing maintenance efficient warehouses that contribute to the enhancement of business performance. Design/methodology/approach – The relations between factors and indicators of building facilities maintenance costs are exami...

The present study is intended to develop a Preventive Maintenance (PM) policy for industrial applications, while considering two different objectives: the first objective is to optimize the total maintenance costs, i.e., the Preventive Maintenance (PM) and Emergency Maintenance (EM) Costs Per Unit Time. (CPUT). The second objective is to design the policy in such a way that the simplicity of it...
