The present paper discusses the development of a Markov model for performance evaluation of coal handling unit of a thermal power plant using probabilistic approach. Coal handling unit ensures proper supply of coal for sound functioning of thermal Power Plant. In present paper, the coal handling unit consists of two subsystems with two possible states i.e. working and failed. Failure and repair...

Redundancy technique is known as a way to enhance the reliability and availability of non-reparable systems, but for repairable systems, another factor is getting prominent called as the number of maintenance resources. In this study, availability optimization of series-parallel systems is modelled by using Markovian process by which the number of maintenance resources is located into the obje...

Aims: The present study aimed to investigate the relationship between self-efficacy, decision-making balance, and change processes with stress management in middle-aged women. Instrument & Methods: This cross-sectional study was performed in 2019 on 600 middle-aged women covered by Bushehr Comprehensive Health Services Centers. The method of sampling was stratified. Data was gathered by demogr...

This study aimed at presenting a method for formulating optimal production, repair and replacement policies. The system was based on the production rate of defective parts and machine repairs and then was set up to optimize maintenance activities and related costs. The machine is either repaired or replaced. The machine is changed completely in the replacement process, but the productio...

A set of technical, administrative and management activities are done in the life cycle of equipment, to be located in good condition and have proper and expected functioning. This is refers to be, maintenance management system (MMS). The framework and models of assessment in order to enhance effectiveness of a MMS could be proposed in two categories: qualitative and quantitative. In this resea...

Equipment logistics, maintenance, and repair are important aspects of construction equipment management. A well-managed equipment fleet helps reduce downtime, as well as total maintenance and repair costs. With quickly growing fleets of equipment, large contractors tend to divert the maintenance and repair of equipment from equipment managers to project managers. As a result, the equipment mana...

This paper will focus on the management and improvement of equipment availability with better prevention of failures. It is focused on one of process control tasks: preliminary risks analysis. The result from this study is a method which empowered engineers and managers decision about actions to implement regarding negative events in their manufacture. The article proposes a risk based maintena...

The software assets that an enterprise applies toward the management of its business processes are bound to evolve in response to business model transformations dictated by changing management environments. Both a given set of software and its associated data form an asset portfolio that needs to be well managed to generate the greatest possible return over time. Tradeoffs between the TCO (Tota...
