Problems solved by technology

[0006] The purpose of the present invention is to provide a pharmaceutical supply chain management system and method based on block chain and edge computing, and hand over the computing tasks required for the block chain nodes to reach a consensus to the edge server to complete, and solve the problem of block chain node computing. Insufficient capacity, improve the management efficiency of the pharmaceutical supply chain; at the same time, use the improved k-means algorithm to deploy the optimal location and the optimal number of edge servers for the blockchain nodes, and improve the resource utilization of the edge servers

Embodiment Construction

[0044] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0045] Such as figure 1 A pharmaceutical supply chain management system based on blockchain and edge computing is shown, including:

[0046] Node information upload module: used to upload the identity information and location of the pharmaceutical supply chain nodes, as well as the blocks that need to be processed and the generation time generated by each node within a period of time;

[0047]Data storage module: used to store the block information sent by the corresponding edge server;

[0048] Data upload module: responsible for uploading new blocks generated by pharmaceutical supply chain nodes to corresponding edge servers;

[0049] Public-private key and identifier storage module: used to store the respective public-private key pairs and identifiers of the pharmaceutical supply chain nodes;

[0050] Identity verification module: used to ver...

Abstract

The invention provides a medicine supply chain management system based on a block chain and edge computing. The medicine supply chain management system comprises a node information uploading module, adata storage module, a data uploading module, a public and private key and identifier storage module, an identity verification module, a public and private key pair distribution module, a node identification module, an edge server deployment module, an edge server information storage module, an edge server processing module, a storage module, a consensus module and an intelligent contract module.According to the invention, the computing task required for the blockchain node to reach the consensus is completed by the edge server, so that the problem of insufficient computing power of the blockchain node is solved, and the management efficiency of the medication supply chain is improved; and meanwhile, an improved k-means algorithm is utilized to deploy the optimal position and the optimalnumber of edge servers for the blockchain node, so that the resource utilization rate of the edge servers is improved.

Description

technical field [0001] The invention relates to a supply chain management system, in particular to a supply chain management system and method. Background technique [0002] The pharmaceutical supply chain management aims to improve the quality of pharmaceutical products, the level of pharmaceutical services, and the overall efficiency of the pharmaceutical supply chain. The entire supply chain is regarded as an integrated organization, and all enterprises on the "chain" are regarded as partners. , The planning, organization, coordination and control of logistics, information flow and capital flow in supply chain activities. Since the pharmaceutical supply chain has the characteristics of multiple circulation links and transaction levels, complex transaction channels, and high storage requirements for pharmaceutical products, the traditional centralized pharmaceutical supply chain management model relies on a core organization to manage the entire supply chain, and the manag...
