Reliability and maintainability of the antitank missile system affect the armament battle effectiveness directly. In this paper, the actuality of a new-style antitank missile reliability and maintainability is analyzed. The existed problems are discussed and the measures needed to enhance the design and tests of reliability and maintainability of the product and the educational level of the operator...
Wind turbine due to economical benefit and environment consciousness has gotten the fast development in these years. Comparing the running experience of American with TPC, we got the same result- high failure rate even 30% in 2008∼2009 and long average repairing period [1]. Reliability of wind turbine is critical to extract maximum amount of energy from the wind and promote the economic performance...
While the demand of electric power increases and the installation space of power equipment is fixed in a factory, the gas insulated switchgear (GIS) is gradually applied to medium voltage system due to its small size and easy maintenance. However, it also takes longer time for the repair of GIS accident. Therefore, the preventive maintenance (PDM) is very important and the most effective method is...
An approximate string query is to find from a collection of strings those that are similar to a given query string. Answering such queries is important in many applications such as data cleaning and record linkage, where errors could occur in queries as well as the data. Many existing algorithms have focused on in-memory indexes. In this paper we investigate how to efficiently answer such queries...
Service discovery of state dependent services has to take workflow aspects into account. To increase the usability of a service discovery, the result list of services should be ordered with regard to the relevance of the services. Means of ordering a list of workflows is a similarity measure of the workflow and a query. In this paper different similarity measures facilitating structured workflows...
As the demand of high power system reliability, condition based maintenance (CBM) becomes a better solution for maintaining equipment reliability. According to the diagnostics of CBM, one can estimate the condition of insulator, and find an optima strategy. Among them, on-line partial discharge measurement is one of the most important diagnostics assessing the condition of insulator. However, the...
Condition information is the important indicator of the equipment healthy management. In order to embody the condition information in the traditional age replacement model, age replacement availability model based condition information is established in the long run. Finally an example is used to demonstrate the relation between condition information and the replacement interval. The application result...
Condition-based maintenance is an advanced maintenance strategy which is based on the monitoring of equipments status and according to the results of monitoring and analysis people can arrange maintenance scientifically. When monitoring and analyzing the status of equipments, there are vast historical and on-line data to analyze. If we can find the main factors leading to equipment failure through...
