Problems solved by technology

[0003] In recent years, a number of methods or frameworks for controlling complex business processes through smart contracts have emerged, but they have problems such as relatively low flexibility and difficult version iterations
In particular, these approaches or frameworks all suffer from a common shortcoming: no proper consideration or lack of time, which is critical in cross-organizational business processes
In fact, blockchain platforms currently have no way to represent time and manage time constraints
Additionally, since a smart contract is transaction driven, it is executed in a closed environment without access to global time information

example

[0081] Definition 14. Scaffolding contract: SC = {TM, V, I, ACC link ,VC link} is a smart contract that stores business process timed orchestration graph TM, model version V and instance I, which passes ACC link and VC link The access control contract ACC and the voting contract VC are linked respectively. Among them, the business process timing diagram TM = {E, M, D, T}, model version V = {(1 ,V 1 >,1 ,V 1 >,1 ,V 1 >,1 ,V 1 >),…,(n ,V n >,n ,V n >,n ,V n >,n ,V n >)}. Instance I = {IE, IM, IG}, where IE, IM, and IG represent instance element, instance message content, and instance global data respectively.

[0082] Based on the above definitions, the specific implementation process of the present invention will be specifically described below.

[0083] Such as figure 1 As shown, the block chain business process management method driven by the timing arrangement diagram of the present invention, the framework of the method is as follows figure 2 As shown, the sp...

Embodiment

[0141] The steps in this embodiment are the same as S1-S7 in the specific implementation manner, and will not be repeated here. Part of the implementation process and results are shown below:

[0142] Cross-organizational business process modeling: The cross-organizational business process used in this example comes from the real product ordering process of a hearing aid company. The product ordering process of the hearing aid company involves multiple process participants, including store customers, manufacturers, and logistics providers. and shipping carrier. The modeling process of timing orchestration diagram during modeling includes the following: (1) Cross-organizational business process orchestration: orchestrate cross-organizational business processes, and add corresponding basic elements including sequence flow of orchestrating activities, events, gateways, and connecting elements . (2) Extended time constraints: The orchestration graph modeling tool used during ...

Abstract

The invention discloses a blockchain business process management method and system driven by a timed layout diagram. According to the method, three types of time constraints of a single duration constraint, an activity maximum duration constraint and an activity interval time constraint of a process activity are introduced, so that effective time management of an on-chain business process is realized. According to the method, an explanatory deployment mode based on the meta-model is adopted, the deployed smart contract can be arranged and reused by different process instances, and different from a one-to-one compilation method of instances and smart contracts during deployment, the method can greatly reduce the consumption of the block chain Gas. According to the method provided by the invention, the problem of trust missing caused by violation of time constraints in a cross-organization business process can be solved, a meta-model version control strategy based on a voting mechanism is integrated, and the method has the advantages of relatively high decentration degree and relatively easy version iteration.

Description

technical field [0001] The present invention relates to the technical field of business process management, in particular to a block chain business process management method and system driven by a timing arrangement diagram. Background technique [0002] With the increasing complexity of business processes, traditional business process management methods can no longer cope with some complex business process scenarios that require cross-organizational collaboration, such as financial education management, medical health management, asset management, supply chain, etc. For these inter-organizational business processes, traditional business process management methods generally use third-party authoritative institutions such as banks and Alipay as central controllers for trust entrustment, but this may lead to increased security risks, low efficiency, and non-traceability of transactions. And other issues. The blockchain Ethereum platform uses smart contracts to automate proces...
