This paper considers a k-out-of-N system with identical, repairable components. Maintenance is initiated when the number of failed components exceeds some critical level. After a possible set-up time, all failed components are replaced by spares. A multi-server repair shop repairs the failed components. The system availability depends on the spare part stock level, the maintenance policy and th...

This research paper focuses on the simulation-based comparative study of several new dispatching rules with the existing ones for the minimisation of flow time based performance measures such as mean flow time, maximum flow time and variance of flow time. The authors have proposed five new flow time based dispatching rules. The best of existing rules such as PT+PW, AT, AT-RPT, FDD and the stand...

Struggling in world's competitive markets, industries are attempting to upgrade their technologies aiming at improving the quality and minimizing the waste and cutting the price. Industry tries to develop their technology in order to improve quality via proactive quality control. This paper studies the possible paint quality in order to reduce the defects through neural network techniques in au...

Both service and manufacturing industries depend on the availability of expensive equipment to deliver their products. Examples of such equipment include aircraft, rolling stock and manufacturing equipment. When this equipment is not working, the primary processes of their owners come to an immediate stop. To reduce the downtime of equipment, companies stock critical components such that the eq...

in this paper, a new approach to overlapping operations in job shop scheduling is presented. in many job shops, a customer demand can be met in more than one way for each job, where demand determines the quantity of each finished job ordered by a customer. in each job, embedded operations can be performed due to overlapping considerations in which each operation may be overlapped with the other...

Computer-integrated manufacturing (CIM), technologies are presented as solutions to manufacturing organizations, which need to perform well in all customer-related dimensions simultaneously. In the literature, CIM technologies providing such benefits as more frequent production changes, reduced inventory level, improved ability of producing complex parts with a high degree of accuracy and repea...
