A method for mining a weak reliability link of a power distribution system based on multi-dimensional analysis

There is provided a method for mining a weak reliability link of a power distribution system based on multi-dimensional analysis. The method comprises the steps of power distribution network power failure event data collecting and cleansing, power distribution network power failure event data CUBE modeling, mined target-based power failure event data CUBE reconstructing, single-dimensional analysis on power failure event data CUBE, multi-dimensional comprehensive analysis on power failure event data CUBE and the like. The method for mining a weak reliability link of a power distribution system based on multi-dimensional analysis breaks through the limitation that the power failure event data is only used for reliability index statistics in the traditional management of reliability of the power distribution network, establishes a multi-dimensional model for the power failure event data itself to execute analysis, and mines the weak reliability link of the power distribution system from multiple perspectives and different hierarchies, thus enabling to effectively find regular features of influence factors on the power failure event of the power distribution network and where the weak reliability link of the power distribution network is, which can not only provide direct guidance for a production-management work of the power distribution network, such as grass-roots operation-maintenance and the like, but also provide a valuable decision basis for each level of management unit of the power distribution system.

Flexible distributed manufacturing method and system therefor

In a manufacturing system that has a plurality of sheet fabrication machines, to enhance the efficiency of the system, there are provided a plurality of databases each for storing particular data relating to the machines, the types of materials to be used, the tooling of the machines, etc. of the system. When a multi-dimensional model of a component part to be produced by the system is input to the system, selective data is retrieved from the various databases so that at least one machine of the plurality of machines of the system is selected to produce the part from a worksheet of a chosen material. Concurrently, or shortly thereafter, a NC part program for programming the selected machine to execute the necessary operations in accordance with a flat drawing generated from the multi-dimensional model to fabricate the component part is generated based on selective data retrieved from the databases. With the NC part program, the selected machine performs the operations necessary for producing the component part from the sheet stock material chosen for the component part. If there are multiple component parts to be produced in the same production run, the system would sort the different parts and arrange for the ordered fabrication of the different parts by respective selected machines equipped with corresponding appropriate NC programs to eliminate any potential bottleneck or conflicts that may arise due to the fabrication of multiple parts by multiple machines during the same production run.
