As the requirement of task is dynamical, the usage of equipment will change with time and it will result in the fluctuating demand for spare parts all over the time. In order to improve equipment performance, the users need to forecast equipment failure frequency and demand for spare parts within the task period. Demand in a moment of task period is the result of cumulative effect of the failur...

In the event of an influenza pandemic, patients with severe acute respiratory failure (ARF) due to influenza will require positive-pressure ventilation (PPV) in order to survive. In countries with widely available critical care services, PPV is delivered almost exclusively through use of full-feature mechanical ventilators in intensive care units (ICUs) or specialized hospital wards. But the su...

Semiconductor Industry (SI) is facing the challenge of short product life cycles due to increasing diversity in customer demands. As a result, it has transformed into a high-mix low -volume production line that requires sustainable production capacities. However, significant increase in the unscheduled equipment breakdowns, limits its success. It is observed that in a high-mix low-volume produc...

Fault prediction is the precondition of Condition Based Maintenance (CBM), accurate prediction for equipment can not only make warning before failure occurs, but also reduce the cost of maintenance of complicated equipment and system. Therefore, it is of profound importance to make research on fault prediction of electronic equipment. This paper analyses some typical fault prediction method of ...

Abstract The author in order to solve the problem of optimizing accuracy mechanical equipment failure detection proposes a vibration signal collection and computer simulation for failure. Using wavelet domain Wiener filtering-based fault method, first combined filtering threshold filtering, established model equipment, obtained true filtered error fusion principle perform orthogonal transform o...

In this article we develop a model to help a maintenance decision-making situation of a given equipment. We propose a novel model to determine optimal life-cycle duration and intervals between overhauls by minimizing global maintenance costs. We consider a situation where the customer, which owns the equipment, may negotiate a better warranty contract by offering an improved preventive maintena...

i needed to dereference the names and descriptions of equipment referred to n the text, and to infer their causal relations and operational states when e s these are only implicitly expressed by the message writer. Knowing th tructural configuration of the equipment is useful in both tasks, and a s a structural domain model can be extracted readily from equipment manual nd their accompanying pa...
