Purpose: The purpose of this paper is to propose a stochastic optimisation model for integrating service and maintenance policies in order to solve the queuing problem and the cost of maintenance activities for public ...

This article proposes a stochastic optimisation model in order to reduce the long-term total maintenance cost of complex systems. The proposed work is based on the following approaches: (i) optimisation of a cost model for ...

This paper offers an original methodology to set multi-dimensional maintenance policies for machines whose aging processes require using multiple time scales. It can be considered a generalization of the traditional approach, ...

A Process Manual. It contains the diagrammed flows of activities, sub processes and processes that, together, make up Macroprocess 10 Information and Communication Technologies.

An appropriate maintenance policy is essential to reduce expenses and risks related to repairable systems failures. The usual assumptions of minimal or perfect repair at failures are not suitable for many real systems, ...

The occurrence of unexpected aircraft maintenance tasks can produce expensive changes in an airline's operation. When it comes to critical tasks, it might even cancel programmed flights. Despite this, the challenge of ...

This paper aims to map and analyze the attention of some actors and institutions on health policies in Brazil between 1986 and 2003. This model of research on the government agenda is known under the term of policy dynamics ...

Gas pipeline systems are one of the largest energy infrastructures in the world and are known to be very efficient and reliable. However, this does not mean they are prone to no risk. Corrosion is a significant problem in ...
