Wind power emerges as a sustainable energy resource to meet the increasing electricity needs in the next 20–30 years. Power volatility and maintenance costs are the key challenges in harvesting this type of renewable energy. The levelized cost of energy (LCOE) allows the utility and investors to compare the costs of various generation technologies of unequal lifetimes and capacities. In this study...
Aiming at the current disadvantages in the maintenance for armored vehicle command control and communication system, this paper introduces the connotation, structure, function, technical attributes and technical elements of PHM. And it proposes that adopting PHM technology in modifying current maintenance support mode is an effective way. The PHM system for armored vehicle command control and communication...
The concept that Mission Based Maintenance Decision-making for Materiel is put forward in this paper. Keeping dependability and operational readiness after mission of material is set as goal, which includes dependability centred maintenance decision-making and operational readiness after mission centred maintenance decision-making for material. The process of mission based maintenance decision-making...
A simulation model for joint optimization of GM and spare part inventory control under infinite horizon is presented through analyzing the characteristic of spare part demand of a system under group maintenance (GM) policy. In this model, maintenance activities of GM and spare supply are simulated using Monte Carlo method, by which costs of repair, spare inventory, and loss of system downtime induced...
This paper develops a METRIC-like model to optimize inventory allocation of repairable spares in a three-echelon supply system. Supply availability is selected as the optimizing object of the model, and the total ordering cost of repairable spares is taken as the constraint condition. The optimal allocation of repairable spares is reached by the marginal analysis algorithm. Then the established model...
Through integrated analysis to the weapon materiel support elements of information flow, material flow, personnel flow and capital flow, this paper formed the civil-military integrated weapon materiel support system based on network and information. Civil-military integrated weapon materiel support operation mechanism is established through the aspects of management operation, support mobilization,...
In order to improve the operational safety and equipment management of nuclear power plants, combined with domestic and foreign nuclear power plants reliability data of actual demands, development of equipment reliability data collection and analysis application platform research work have been performed. This paper presents the research technique and research ideas, establishes the reliability of...
According to the current circumstances, the cultivating and training of the newest armored equipments maintenance support personnel is difficult to meet army's demand all the time, and can't meet the needs of equipments development either, we researched the maintenance training simulation system which is basic to half-practicality and virtual reality technology in chief. We made the overall design...
Based on the foundation of mission successfulness, we put forward the concept of mission maintainability assessment. Analyzing the general process of mission maintainability assessment of complex system and studying the basic method of mission maintainability assessment. Based on the state evaluation of related functional unit, we put forward the thoughts that parallel part as a whole which contain...
As a fusion of lean efficiency engineering and six sigma quality control, Lean Six Sigma can be applied to quality management of equipment maintenance, to improve the deficiencies and inefficiency in equipment maintenance process. Regarding the state of the equipment maintenance process, the paper researches the Lean Six Sigma implementation in quality management of equipment maintenance, which can...
According to the problems and difficulty of high-tech equipment M&S, the shortcomings of existing equipment maintenance & support (M&S) mode are analyzed in this paper. The new mode of high-tech equipment M&S is presented from innovating M&S mechanisms, improving maintenance means and the material supply & inventory system, optimizing the personnel training system and other...
Equipment contractor support is the innovative practice and urgent requirement to promote new-type equipment forming operational and support capability. The support delay time is a significant discrimination between contractor support and Army support. As concerned breach of contract problem, the paper will take research on three kinds of support delay time: non-repair parts supply delay time, personnel...
In this paper, considering the development of China's socialist market economy and the actual situation of our army's civil-military integration system, the development of the socialist market economy and the building of our army's equipment maintenance system are creatively combined closely, the risks of the construction of civil-military integration equipment maintenance support system are analyzed,...
Treating product quality as the ultimate embodiment of military product quality has been paid more and more attention to. Taking necessary measures and management methods to evaluate product using quality and effective control of product quality, has become urgent need to solve the problem. This paper described using quality of product, quality information, the basic concept of quality evaluation...
With the analysis of system failure process, five states of each component are proposed for repairable complicated system, namely the operating state, the repairing state, the failed and waiting repair state, the repaired and inactive active state, and the state of taken out of operating. Using the method of component state trace, a calculating method of system normal or failed states is presented...
Under the assumption that time to failure and time to repair of unit are exponentially distributed, this paper presents a general procedure for conducting an inherent availability test with fixed sample size of two-unit same redundant system. Above all, two design principles for general availability test procedure of redundant system are presented. One is that ensuring stated levels of producer's...
Reliability and availability have always been important characteristics of systems but become even more critical and complex issues on networks. Due to the high complexity of accurate calculation methods, simulation methods for network reliability and availability evaluation have been a popular area of research, and received significant attention. In this paper the network topology model, the failure...
The paper analyzes the conception and the measuring model of operational availability. For the restrictions of present models' assumptions, an instantaneous operational availability model and an average operational availability model for evaluating material availability together with a simulation method for the two models are put forward. The distinctions between the two models are also given by the...
One of the major obstacles in developing Health Management System (HMS), by using intelligent technologies for diagnosis, prognosis, maintenance and health management of aerospace, is the correct description of knowledge. The work proposed in this paper suggests a normative knowledge representation frame based on ontology to integrate Knowledge related to Health Management of Aerospace (AHMK). In...
In this paper, we presented a simulation based model to analysis the reliability of phased-mission system (PMS) with repairable components. Many researches on the repairable PMS supposed that failed components would be repairable only when the system is in a good state. It is different here that failed components can be repaired no matter what state is the system in. The mission successes if and only...
