and S2, planning and allocating material demands through the intelligent contracts of the block chain network, and outputting a better allocation strategy to manual selection through an allocation scheme comprehensive evaluation algorithm according to the results returned by each intelligent contract.
The following will explain the above steps in detail, the system architecture diagram of the present invention is shown in fig. 2, a block chain is used as a bottom data storage platform as a support, a supply chain management part, an emergency storage part, each provincial and urban level warehouse management parts, and each level of emergency repair management parts are used as block chain nodes, each node issues data (including disaster-suffering condition information, each level of warehouse inventory information, supplier information checked by south network, etc.) generated by each department in the participation process to the block chain network, performs format conversion by a data uplink intelligent contract, and stores the data in the block chain so as to share the data among the nodes.
When an emergency repair accident occurs, an emergency repair department issues an emergency affair through a block chain network, a block chain intelligent contract layer is called through an intelligent contract interface to respond to an intelligent contract, and a material purchasing demand plan and a material allocation scheme are carried out manually by the aid of the intelligent contract.
The traceability anti-counterfeiting characteristic based on the block chain technology can avoid the defect of centralized management of information by a traditional centralization mechanism, and has the advantages of decentralization, tamper resistance, high data security and the like. The data information of the whole process is recorded by a block chain technology, when the data information is used in an emergency event, the intelligent contract auxiliary front line of a block chain intelligent contract layer is triggered to analyze and decide by a contract triggering condition, and the following intelligent contracts are specifically designed:
the method comprises the steps of setting up an intelligent contract according to the demand, acquiring damage degree data of equipment on a disaster site on a chain, triggering the intelligent contract to execute a demand analysis instruction, outputting a material demand list, and improving the efficiency of manually setting up a demand plan.
The intelligent contract for material allocation acquires corresponding material storage data and frame agreement supplier data of internal warehouses at all levels through a chain, triggers and executes a strategy analysis instruction, selects the shortest path and the most appropriate conveying method through an algorithm, and outputs the optimal strategy for material allocation to manually select the final material allocation scheme.

The design and execution flow of the intelligent contract is shown in fig. 3, and the specific steps are as follows:
step 1: the front line emergency repair department sends an emergency material demand purchasing affair broadcast to the chain, wherein the affair comprises the emergency accident occurrence place, the emergency material damage type and quantity, the material demand delivery time and the like.
Step 2: after the emergency affairs are broadcasted in the alliance chain network, the requirement on the trigger chain is made into an intelligent contract, the intelligent contract executes a chain code function UploadTransData (), an emergency procurement requirement list is added to the block chain, and the affair list structure is as follows:
Translist struct{
Trans_Index:
Trans_ID:
Adress:
Requier：
Diedline:
}
the fields are described as follows:
and step 3: after the requirement formulation intelligent contract execution chain code UploadTransData () generates an emergency material purchasing requirement uplink, triggering the intelligent contract for material allocation on the chain and a supplier to select an intelligent contract, and simultaneously executing the step 4 and the step 8.
And 4, step 4: and the material allocation intelligent contract executes a chain code function GetneighborData () and acquires inventory data (data fields comprise inventory addresses, inventory types and inventory quantity) of each warehouse in the power grid which is stored on a chain and is close to an emergency repair site by taking the position of the warehouse as a data searching condition.
And 5: then, using the returned data result to execute a chain code function CheckCount () of matching the warehouse inventory and the demand, if the warehouse inventory meets the emergency demand, returning the material storage warehouse ID and the inventory data, and going to step 9; and if the warehouse inventory does not meet the emergency requirement, outputting fail and turning to the step 6.
Step 6: and executing a chain code function Getinternaldata (), acquiring inventory data of other warehouses inside the south network, returning warehouse IDs and inventory data meeting emergency requirements to the SDK interface for calling, and turning to the step 7.
And 7: and executing a chain code function of matching warehouse inventory and demand with CheckCount () and returning the warehouse ID and inventory data meeting the first-aid repair demand to the SDK.
And 8: calling a supplier to select an intelligent contract, executing a chain code function GetexternalData (), acquiring supplier data in a frame bidding protocol on a chain, returning a supplier warehouse address, a stock material type and the quantity of each stock material which meet the search condition, executing a CheckCount () chain code function, returning a supplier ID and corresponding warehouse data which meet the first-aid repair requirement, and returning the supplier ID and the corresponding warehouse data to an SDK (software management tool).
And step 9: finally, according to the result of the adjustable material supply points returned by each intelligent contract, the map software and the material supply management system are combined to obtain the related data of the transportation distance, the vehicle oil consumption and the distance time from each supply point to each demand point; and then calling a comprehensive evaluation algorithm of the material allocation scheme, analyzing through the algorithm and outputting a better allocation strategy to manual selection.
For emergency repair of electric power supplies, the demand is urgent, and the supplies must be rapidly delivered to the required places. When executing the electric power emergency material allocation scheme, two factors are mainly considered: transportation cost factor C and transportation timeliness factor D, transportation timeliness index is mainly considered in the electric power emergency material allocation scheme. The comprehensive evaluation indexes are as follows: f ═ μ C + ν D. Wherein mu is the reference weight of the transportation cost, and upsilon is the reference weight of the transportation timeliness. This weight can be determined according to the actual requirements, if in a very urgent case only the timeliness needs to be considered, then μ is 0. The specific flow of the comprehensive evaluation algorithm of the allocation scheme is as follows:
1. calculating a transportation cost factor C for each supply pointi
Cost factor of transportation CiThe method comprises the steps of comprehensively utilizing various parameters such as labor cost, vehicle loss, fuel oil cost, maintenance cost and the like; in particular, transportation cost factor CiThe larger the transport costs are; thus, transportation cost factor CiThe smaller the better;
is provided with n emergency material supply points, m indexes and CijThe value of the jth index for the ith supply point.
a index normalization process
Because the measurement units of the indexes are not uniform, before the indexes are used for calculating the comprehensive indexes, the indexes are standardized, namely, the absolute values of the indexes are converted into relative values. Because the lower the transportation cost index value, the better, the data standardization processing is carried out by adopting the following algorithm:
b, calculating the proportion of the ith supply point in the jth index in the index:
c, calculating the entropy value of the j index:
wherein k is 1/ln (n) > 0.
d, calculating entropy redundancy:
dj＝1-ej。
e, calculating the weight of each index:
f calculating the integrated value of each supply point:
2. transport aging factor
The transportation aging factor is standard time output according to the map software, and the transportation aging factor D is also requirediCarrying out standardization treatment, namely calculating the proportion of the ith supply point in the transportation aging index:
3. composite index of supply points
Using the formula Fi＝μCi+υD′iAnd calculating a comprehensive evaluation index of each supply point.
The lower the comprehensive index is, the more suitable the material allocation is. Therefore, the supply points are sorted from low to high according to the comprehensive index, and the sorted list of the supply points is output for manual auxiliary decision making.
The invention also provides an auxiliary electric power emergency material digital purchasing device based on the block chain, which comprises:
the block chain system is used for managing emergency material data information and uplink transmission;
the intelligent contract module comprises a demand-made intelligent contract, a material allocation intelligent contract and a supplier selection intelligent contract, and is used for analyzing and deciding an intelligent contract auxiliary front line of a block chain intelligent contract layer;
and the allocation scheme comprehensive evaluation module is used for taking the results returned by the material allocation intelligent contract and the supplier selection intelligent contract as input, analyzing through an allocation scheme comprehensive evaluation algorithm and outputting a better allocation strategy.
Through a block chain network constructed by the system, each change of data can be permanently recorded in the chain, and meanwhile, all information on the chain is completely disclosed and can be traced in the whole process, so that the authenticity of the data is ensured.
On the basis that data cannot be changed, rule terms are written on a block chain in advance in a code mode by the intelligent contract technology, and an algorithm inside the contract is automatically executed immediately after preset conditions are met.
Through a block chain network constructed by the system, each change of data can be permanently recorded in the chain, and meanwhile, all information on the chain is completely disclosed and can be traced in the whole process, so that the authenticity of the data is ensured.
During emergency repair, due to the urgency of the situation, when purchasing and allocating materials to a provider, a public bidding approach is not taken, the provider is selected from the bidding providers, and then the provider supply is organized in a non-bidding manner, and then procedures such as supplementary purchasing, contract signing and performance are conducted. The manner in which the purchase contract is replenished at this time is likely to subsequently render the supply reality uncertain. The characteristics of decentralization and safety of the block chain technology are applied to the purchase of emergency repair type materials, when an intelligent contract automatically generates a deployment result, data are linked and stored, so that the safety and the authenticity of finance of an enterprise and related original certificate data are guaranteed, the subordinate branch service management nodes in the enterprise are identified, and each branch service node is a component of a maintenance system and stored data, so that the management and maintenance cost of the data is reduced.
