Sewers, water pipes, and streets are elements of our civil infrastructure, the supporting structure of society. Infrastructure is a complex technical system that provides us with a varied range of essential services; a storehouse of resources and wealth that each generation inherits, uses, and passes on to succeeding generations. The asset management has a big influence on infrastructure develo...

Production planning and maintenance are two important problems in manufacturing systems. Despite the relationship exists between these two problems due to sudden failures and production capacity occupied by maintenance activities, each of these problems planned separately and as a result program and model efficiencies reduce in the real world. The aim of integrated production and maintena...

Track Maintenance is crucial for the safe and efficient of railway transportation. After analysis of foreign management techniques for high-speed railway track maintenance, combined with the characteristic of passenger dedicated line in China, this paper has explored new ideas of the information system of passenger dedicated line track maintenance and at the same time researched on the theory a...

maintenance treatment for patients with acute myeloid leukemia (aml) in remission has recently been controversially discussed and even abandoned by several groups. an analysis of 16 published multicenter trials, however, revealed the highest probabilities of relapse free survival (rfs) in the range of 35-42 % at 4-5 years only in patients assigned to maintenance treatment when adult age and int...

this paper studies a maintenance policy for a system composed of two components, which are subject to continuous deterioration and consequently stochastic failure. the failure of each component results in the failure of the system. the components are inspected periodically and their deterioration degrees are monitored. the components can be maintained using different maintenance actions (repair...

This paper discusses a scheme that allows all parties involved in the maintenance of a chemical plant: the plant owner (customer), the engineering company, the equipment vendors, and the maintenance firms, to form a virtual service enterprise (VSE) whenever a maintenance service is necessary, in an attempt to provide required services more timely. This paper also discusses the requirements for ...

This paper presents the development of a generic framework for asset maintenance management, and an object model for the maintenance management of roofing systems as a case study to demonstrate the applicability of the framework. The model builds upon the Industry Foundation Classes (IFCs) to define object requirements and relationships for the exchange and sharing of maintenance information be...

Buildings are designed and built to sustain its initial functions and beauty for both the present and future users. Building required maintenance for high performance regardless of whether it meets the sustainability consideration or not. An important segment in the maintenance management system is the identification and analysis of defects in the buildings and the urgency of repair needed. Def...

Terology is defined as the combined use of techniques of operational research, information systems and engineering, with the objective of accompanying the life cycle of facilities and equipments; it includes the definition of specifications referred to its purchase, installation and reception, as well as the management and control of its maintenance, modification and substitution and, still, it...
