In equipment joint support, support tasks generated by different equipment share the resource of the support sites. Compared to conventional support system, more categories of support objects leads to a sharp increase in the number and randomness of support tasks. This makes the progress of some support activities affected by the resource occupation of other activities. In other words, the availability...
Requirements Engineering (RE)[1] refers to the process of formulating, documenting and maintaining software requirements[2] and to the subfield of software engineering concerned with this process. In requirement engineering phase we can gather the requirements from user and use this requirement for software development and produce software products that satisfy the user needs. Various models such...
An advance in technology unlocks new opportunities for organizations to increase their productivity, efficiency and process automation while reducing the cost of doing business as well. The emergence of cloud computing addresses these prospects through the provision of agile systems that are scalable, flexible and reliable as well as cost effective. Cloud computing has made hosting and deployment...
Proteus is an open-source simulation program that can predict the risk of data loss in many disk array configurations, among which, mirrored disks, all levels of RAID arrays and various two-dimensional RAID arrays. It characterizes each array by five numbers, namely, the size n of the array, the number nf of simultaneous disk failures the array will always tolerate without data loss, and the respective...
The present generation business world does not work as a standalone system but requires the collaboration of various enterprises to achieve a desired goal. These enterprises are designed on the paradigm of web services and the maintenance of these web services is an implicit requirement. The maintenance of the services include extending the existing service, reusing the available services and remodel...
An Integrated Environment of Maintainability design and analysis was put forward based on Concurrent Engineering(CE) theory. As enabling technology and software platform for CE, the Product Lifecycle Management(PLM) could be regarded as the data source and the management platform of Maintainability design and analysis. After discussing the information requirements and Entity Relationship(ER) model...
Equipment faults will produce irreversible effects for a maintenance support system. Based on the change of maintenance support resource in a maintenance support organization, maintenance support process, and external environment, the concept of maintenance support system entropy is proposed. Without considering time and cost, it is carried out from three aspects which are organizational structure...
Natural disasters of China mainland mainly include earthquake disaster, geological disaster, sandstorm, typhoon, flood, thunderbolt, snowstorm, low-temperature sleet and freezing. For enhancing the emergency response capacity of power communication network, impact of the natural disasters on power communication facilities was analyzed. The disasters categories and distribution were introduced. China...
To study the material support system, build a simulate system is an efficient way. The complicity of the material support system is analyzed, the similarities and differences of the mission for materials, transport system, and support stations to carry out is proposed; then an element mission model for general use is constructed, based on which the multi-level mission model is set up and expressed;...
The quasi-three-stage inventory model based on Three-echelon Assembly relationship was established relying on background of repairing and accommodating for PLA's weapon equipment valuable spare parts in the paper, borrowing ideas from research production of foreign repairable spare parts inventory theory and researching on classical VARI-METRIC model and its theory. By discussing parameters of spare...
Software industry is gaining momentum due to profound impact on the productivity of the various tasks. Typically software development life cycle includes, development activity and post release activities. The post release activities cover software maintenance and support. It is inevitable to deny the significance of software maintenance and support activities due to fairly a large size of the software...
Applying domain engineering, the equipment maintenance support system is analyzed and the essential entities are abstracted. Using the executable specification tool-ExSpect, a domain library is constructed, including maintenance organization module, distribution stock module, transport unit module and management department module. By constructing the simulation Object Model (SOM) and the Interface...
Modern business process modeling languages such as BPMN or EPC provide users with more constructs to represent real world situations than their predecessors such as IDEF or Petri Nets. But this apparent increase in expressiveness is accompanied by an increase in language complexity. In practice many organizations choose to only use a subset of the available modeling constructs. Using a well established...
The Open Distributed Processing Reference Model (ODP-RM) provides viewpoints and abstract infrastructure guidelines that can be used for a basis for enterprise architecture, especially for an inter-enterprise architecture. The ODP-RM does not prescribe methodology for modeling itself, but provides common vocabulary and focus for description. This paper performs a brief analysis of the ODP-RM (and...
