We consider a production-inventory system that consists of an input-generating installation, a production unit and L intermediate buffers. It is assumed that the installation transfers the raw material j ∈ {1, . . . , L} to buffer Bj, and the production unit pulls the rawmaterial j ∈ {1, ..., L} from buffer Bj. We consider the problem of the optimal preventive maintenance of the installation if...

In the special machines and custom made machine industry, machine manufacturers have to deal with maintenance services in spread market, while individualization of customer demands increases complexity to maintenance services. That is the case in stone cutting machines manufacturing business, where maintenance is a critical factor because of the high customization of each machine and because of...

For large sized glass handling robot, reliability improving activity increases the importance. The activity is divided into two phases of design phase and line usage phase. At the design phase, accurate simulation for keeping the limitation of material or gear strength and accurate torque control are the key. At the line usage phase, supporting tool for preventive maintenance activity is the ke...

The problem of integrated production and maintenance control unreliable manufacturing systems evolving in a stochastic dynamic environment is studied this paper. considered system subject to degradation the produced products are perishable with random shelf-lives. literature operations management for reports correlation between shelf-life product machine degradation. In fact, latter results she...

In this paper, a new method for modelling and estimation of reliability parameters of power transformer components in distribution and transmission voltage levels for preventive-corrective maintenance schedule of transformers is proposed. In this method, with optimal estimation of Weibull distribution parameters using least squares method and input data uncertainty reduction, failure rate and p...

The IEEE 802.16m standard for Advanced mobile broadband wireless access provides a seamless application connectivity to other mobile and IP networks like UMTS, LTE and WLAN. In order to meet the ubiquitous service delivery for users, Wimax 16m supports integration of these diverse networks which are having great difference in terms of data transmission rate, Coverage, cost and supporting of ser...

in today's competitive market, quality has an important role in manufacturing system. the manufacturers attempt to maintain their production system in a proper condition to produce high quality products. one of the key factors to achieve this goal is maintenance policy. most studies on maintenance focused on machines and less attention has been paid to human resources as the most important...

I n the past many decades, breakdown, maintenance and replacement issues of deteriorating machines and systems are extensively studied within the literature. A number of maintenance and replacement models, techniques and policies are created, documented and tested. However, of these models are comprised of some classes ∗M.Tech. Student, Department of Mechanical Engineering, Madhav Institute of ...
