Evaluating maintenance policies by quantitative modeling and analysis

Evaluating maintenance policies by quantitative modeling and analysis

The growing importance of maintenance in the evolving industrial scenario and the technological advancements of the recent years have yielded the development of modern maintenance strategies such as the condition-based maintenance (CBM) and the predictive maintenance (PrM). In practice, assessing whether these strategies really improve the maintenance performance becomes a fundamental issue. In...

Modeling and Availability Analysis of Internet Data Center with various Maintenance Policies

In this paper, the authors have focused on the stochastic analysis of an internet data center (IDC), which consists of a database main server connected to a redundant server. Observing the different possibilities of functioning of the system, analysis has been done to evaluate the various reliability characteristics of the system. The system can completely fail due to failure of redundant serve...

modeling loss data by phase-type distribution

بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...

Quantitative Determination Of Optimal Fiscal And Monetary Policies: A Stochastic Optimal Control Analysis For Iran

Modeling and Analysis of Concurrent Maintenance Policies for Data Structures Using Pointers

We present a state reduction method that effectively reduces a two-dimensional Markov model to a one-dimensional Markov model for the performance analysis of a class of concurrent data structure maintenance policies. The reduced model allows the derivation of a closed form expression for the average service time per operation and facilitates the identification of priority allocation functions u...
