the present paper deals with development of a simulation model for the performance evaluation of feed water system of a thermal power plant using markov birth-death process and probabilistic approach. in present paper, the feed water system consists of four subsystems. after drawing transition diagram for feed water system, differential equations are developed and then solved recursively using ...

In this work, the effectiveness of preventive maintenance scheduling (PMS) decisions was reported based on a techno-economic model that reflects cost objective function for ship maintenance activities. With a potential to impact on both transportation businesses and users of transportation services, the model provides an alternative to the combined classical literature problems of spare-parts i...

Maintenance can be the factor of either increasing or decreasing system's availability, so it is valuable work to evaluate a maintenance policy from cost and availability point of view, simultaneously and according to decision maker's priorities. This study proposes a Partially Observable Markov Decision Process (POMDP) framework for a partially observable and stochastically deteriorating syste...

Predicting the maintenance and management costs and replacement age of tractors in agricultural mechanized units, is important from several points. So, doing a timely agricultural operations, more accurate measure of the amount of income  including the cost of these items , determining the useful life of old tractors , replacement age, cost of the process changes and the possibility of examinin...

integrated urban management means adopting a holistic approach to urban management and designing appropriate mechanisms for this approach’s requirements in practice. the integration of the urban activities brings together organizational , structural and institutional activities and action in which the urban development is supported. in order to achieve integration, it is essential to identify f...

Transformation of equipment manufacturers to become providers of industrial services is a trend that involves deep transformation of companies. Equipment manufactures can potentially provide services significantly more efficiently and effectively by utilizing information about their installed base. We aim to recognise decision support functionality and required information contents for a system...

today’s world economy situation forces enterprise organizations toward more soft and flexible organization, management, and production processes. they need to explore the most suitable knowledge management (km) tool not only to identify gaps and overlaps but also to maintain and support innovation cross organizations. in this study, a multiple-experts-multiple-criteria decision making model is ...

This paper introduces a model to make decision on the maintenance of a mechanical component subject to condition monitoring. A stochastic model is used to determine what maintenance action should be taken at a monitoring check and the follow up inspection times. The condition of component has a stochastic relation with measurements. A new state space model is developed and used, to predict the ...

Abstract The operation of large production assets requires many decisions from the acquisition and design new to choice lubricant for a specific piece equipment. made in maintenance have direct effect on management process, making it important ensure correct decision making. However, studies tend focus smaller areas being but rarely entire process. To introduce more that consider this paper pro...
