Resources allocated to software maintenance constitute a major portion of the total lifecycle cost of a system and can e€ect the ability of an organization to react to dynamic environments. A major component of software maintenance resources is analyst and programmer labor. This paper is an experimental evaluation of how the Human Information Processing (HIP) model can serve as a framework for ...

Today’s competitive environment requires that industries succeed in sustaining full production capabilities, while minimizing capital investment. From a maintenance perspective, this means maximizing equipment reliability (i.e., achieving maximum uptime), while extending the plants life. This proactive approach needs a Total Planned Quality Maintenance (TPQM) program, the systemizing of all (i....

The present paper deals with the concept, introduction and implementation approach of Total Productive Maintenance (TPM) in detail. TPM is a maintenance program which involves a newly defined concept for maintaining plants and equipment This paper will define TPM history, benefits, it’s (TPM) strengths as a maintenance philosophy, its implementation approach, difficulties in it’s implementation...

In this paper, we propose a new method for scheduling of maintenance operations in a manufacturing system using the continuous assessment and prediction of the level of performance degradation of manufacturing equipment, as well as the complex interaction between the production process and maintenance operations. Effects of any maintenance schedule are evaluated through a discrete-event simulat...
