Abstract The aviation industry is characterised by high manufacturing requirements of products with difficult-to-machine materials to ensure quality and safety. Standardised secured processes transparency in resource material flows within production are important for meeting these safety standards while staying competitive on the market. Those also apply a companies’ tool management be met an o...

This paper presents an innovative approach in supporting tlie operation of complex equipment. The concept was developed in the context of the KoBaS project (Knowledge Based Customized Services for Traditional Manufacturing Sectors Provided by a Network of High Tech SMEs) whose main objectives are the development of new knowledge based tools jbr an intelligent use and management of more sophisti...

The demand for distinct wafer types in semiconductor manufacturing is an explicit function of the electronic components in which these wafers are used. Given that the component demands vary not only by the product type but also over time, it is obvious that wafer demands are also lumpy and time varying. In this paper, we discuss strategic level investment decisions on procuring new equipment an...

According to abrasion process of machine equipment parts of overhead line system for traction power supply and characters of wear-out failures, considering on factor changes of all kinds of production conditions in practical operation, set permit of abrasion loss in coordinating with normal distribution, and abrasion loss of parts as random variables, and then establish the relation between mai...

This paper presents a special case of integration of the preventive maintenance into the repair/replacement policy of a failure-prone system. The machine of the considered system exhibits increasing failure intensity and increasing repair times. To reduce the failure rate and subsequent repair times following a failure, there is an incentive to perform preventive maintenance on the machine befo...

Most manufacturers use human-machine systems to produce high-quality products. Dealing with human-machine systems is very complicated since not only machines should be utilized in proper condition but also appropriate environment should be provided for human resources. Most manufacturers have a maintenance plan for machines but many of them do not have a proper work-rest schedule for human reso...
