In this paper, the dewatering and screening process of vibrating-dewatering screen is studied by combination simulation test physical experiment. The model established method computational fluid dynamics (CFD) discrete element (DEM). Subsequently, efficiency processing are defined as evaluating indexes for performance screening. Four parameters amplitude, vibration frequency, vibrating directio...

Abstract Maintainability is one of the design parameters (reliability, availability, maintainability, and safety (RAMS)) maintenance needed to keep respective in sustainable use. At same time, human involved form interface interaction an engineered product/system designed. Ergonomics a multi-disciplinary science that considers capabilities limitations broader sense. The objective this paper int...

A detailed analysis is performed on a dataset of failure and maintenance records from various onshore wind farms located in different geographical areas for the safety, risk, reliability, availability, maintainability characterization turbines. Specifically, characteristics related to failures, including criticality modes, frequencies, rates, lifetime distributions components, are analyzed supp...

An original maintenance decision making tool based on Bruss theorem has previously been investigated by the authors to select the optimal last production stoppage convenient to operate a maintenance action on a component according to its conditions of degradation. This stoppage is optimal with respect to the combination of antagonistic criteria such as maintainability and reliability. The appro...

Clustering methods are promising tools for ensuring the network scalability and maintainability of large-scale flying ad hoc networks (FANETs). However, due to high mobility limited energy resources unmanned aerial vehicles (UAVs), it is difficult maintain reliability extend life FANETs. In this paper, a new K-means algorithm developed, dynamic transmission power cluster heads based clustering ...

The change of market and the explosion of product variety have led to increased automation and the need for complex equipment. Therefore, the reliability and the maintainability of the equipment play an important role in controlling both the quantity and quality of the products. In order to ensure specified availability and reliability of production process, preventive maintenance (PM) should b...

This paper explores the impact of the size of a staff of equally trained maintenance technicians on the productivity of a serial production line. First, we use the reliability and maintainability characteristics of the line to derive optimal preventive maintenance (PM) policies for each unit of equipment. Second, we use simulation modeling to evaluate the performance of the line assuming all re...
