The analysis server is used for receiving the inventory quantity set of various power grid articles in each power grid article warehouse sent by the article inventory quantity counting module, receiving the demand quantity of various power grid articles in each power grid article demand station needing article supply sent by the demand quantity analysis module, and receiving the driving distance acquisition moduleThe running distance set from each power grid article warehouse to each power grid article demand station needing article supply is sent, the priority influence weight coefficient corresponding to the power grid article stock and the supply and demand running distance stored in the storage database is extracted, and the supply and demand priority coefficient of each power grid article warehouse to each power grid article demand station needing article supply is calculatedξⁱ _vThe priority coefficient of supply and demand of the ith power grid goods warehouse to the v power grid goods demand station requiring goods supply is represented, alpha and beta are respectively represented as priority influence weight coefficients corresponding to the power grid goods inventory quantity and the supply and demand travel distance, and x_ia_jExpressed as the inventory quantity, z, of the jth type of grid items in the ith grid item warehouse_vb_j' expressing the demand of the jth type of electric network goods in the v electric network goods demand station needing goods supply, e expressing a natural number equal to 2.718, d_ib_v' represents the driving distance from the ith electric network goods warehouse to the v-th electric network goods demand station needing goods supply, v represents the number of the electric network goods demand stations needing goods supply, and the priority coefficient of supply and demand of each electric network goods warehouse to each electric network goods demand station needing goods supply is sent to the goods supply and demand management center.

The storage database is used for storing standard stock quota of various power grid items in the power grid demand station, and storing priority influence weight coefficients corresponding to the stock quantity of the power grid items and the supply and demand running distance, and the priority influence weight coefficients are respectively marked as alpha and beta.

The article supply and demand management center comprises a priority coefficient sequencing unit, which is used for receiving the priority coefficients of supply and demand of the power grid article warehouses to the power grid article demand stations needing article supply, sent by the analysis server, the priority coefficient sequencing unit is used for sequencing the priority coefficients of supply and demand of the power grid article warehouses to the power grid article demand stations needing article supply, sequencing the priority coefficients from high to low in sequence, counting the power grid article warehouses which are corresponding to the power grid article demand stations needing article supply and are sequenced according to the priority coefficients, and supplying and demanding various power grid articles to the power grid article demand stations needing article supply according to the priority supply and demand principle, so that the problem that the running distance from part of the power grid article demand stations to the power grid article warehouses is overlarge is avoided, and the supply and demand time of the power grid inventory articles is reduced, the supply and demand efficiency of the power grid inventory items is improved, and the supply and demand level of the power grid items in the power grid item demand station is further improved.

The priority supply and demand principle in the article supply and demand management center comprises the steps of firstly screening power grid article warehouses with first supply and demand priority coefficients corresponding to power grid article demand stations needing article supply, and sequentially carrying out various power grid article supply and demand, and if the supply and demand of certain types of power grid articles in a certain power grid article demand station needing article supply are not met, screening the power grid article warehouses with second supply and demand priority coefficients corresponding to the power grid article demand stations again, and carrying out corresponding power grid article supply and demand.
