Most production scheduling problems, including the standard flexible job-shop scheduling problem (FJSP), assume that machines are continuously available. However, in most realistic situations, machines may become unavailable during certain periods due to preventive maintenance (PM). In this paper, a flexible job-shop scheduling problem with machine availability constraints is considered. Each m...

B. Gajdzik, The Silesian University of Technology, Faculty of Materials Science and Metallurgy, Katowice, Poland The content of this publication consists of notions connected with Total Productive Maintenance (TPM) in metallurgical enterprise. The basic areas of devices condition management through Autonomous and Professional Maintenance are described here. Mentioned areas of activities are per...

We address the assessment and improvement of the software maintenance function by proposing improvements to the software maintenance standards and introducing a proposed maturity model for daily software maintenance activities: Software Maintenance Maturity Model (SM). The software maintenance function suffers from a scarcity of management models to facilitate its evaluation, management, and co...

This paper investigates scheduling problems with simultaneous considerations of deterioration effects and deteriorating multi-maintenance activities on unrelated parallel machines. We examine two models of scheduling with the deterioration effect, namely the job-dependent and position-dependent deterioration model and the time-dependent deterioration model. We assume that each machine may be su...

OBJECTIVE The purpose of this study was to examine the relationship between work environment and the competency maintenance activities of occupational therapists. METHOD A survey of 121 occupational therapists in three states and interviews with 8 occupational therapists in Ohio were used. RESULTS Analysis of survey data indicated that workplace support and the degree of competency monitori...

Component-based software engineering has been increasingly adopted for software development. This approach relies on using reusable components as the building blocks for constructing software. On the one hand, this helps improve software quality and productivity; on the other hand, it necessitates frequent maintenance activities, such as upgrading third party components or adding new features. ...

In maintenance of (public) infrastructures, such as the national highway network, an asset manager is responsible for high network quality and throughput, while limiting expenses to a minimum. The maintenance activities, however, are often performed by commercial contractors, mainly driven by profit. Using a network-based payment mechanism we align the objectives of both stakeholders. Nonethele...

David Ribes What are the utilities, values, dangers and proclivities in the use of the analytical terms “maintenance and repair"? In this article I focus on activities within sociotechnical systems that are sustained by relatively few technologies, but a great deal of social or emotional work. I do so to explore two analytical uses of maintenance and repair, and then to point out some of the da...
