Age replacement policy is concerned with finding an optional time tominimize the cost, at which time the unit is replaced even if itdoes not fail. So far, age replacement policy involving random agehas been proposed. This paper will assume the age of the unit is anuncertain variable, and find the optimal time to replace the unit.
A new component replacement analysis method to solve asset replacement problems for complex electricity distribution systems is developed. In the present model a Taylor series expansion is used to approximate the associated opportunity cost for each component in the system. The method is based on an iterative dynamic programming and integer programming methods to obtain optimal system-level com...
Clickstream analysis provides valuable insight into the behavior of users and can be translated into better business opportunities and increased user satisfaction. A fundamental problem in clickstream analysis is the computation of the distance (or the similarity) between two clickstreams. While, there exists a considerable amount of literature which propose methods of computing path similariti...
This paper studies an M/G/1 repairable queueing system with multiple vacations and N-policy, in which the service station is subject to occasional random breakdowns. When the service station breaks down, it is repaired by a repair facility. Moreover, the repair facility may fail during the repair period of the service station. The failed repair facility resumes repair after completion of its re...
A new replacement analysis methodology is developed to determine system-level component replacement schedules for radial electricity distribution configurations composed of sets of heterogeneous assets. The proposed model is an iterative combined dynamic programming and integer programming approach to obtain cost-efficient system-level component replacement schedules with the objective of minim...
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...
Among the un-market services provided by forest ecosystems, absorption and storage of CO2 (Carbon Sequestration) are very important. Today, Greenhouse Effect is regarded as one of the major environmental problems. In present study, the rate of carbon sequestration of Quercus branti in protected region of Shaho located in Kurdistan province, was evaluated and valued. Random systematic Sampling w...
