The application discloses a cross-industry supply chain supervision method based on multi-chain cooperation, a business sub-chain is used for recording internal information of enterprise transaction subjects and business data of various supply processes; a transaction main chain is mainly responsible for transaction implementation and interaction between different businesses, and records circulation states and transaction data of commodities at various links of the supply chain; and a supervision chain is used for supervising and auditing transaction data between different businesses of the supply chain. The application combines an identity-based encryption mechanism based on fine-grained privacy protection, protects the privacy of multi-party cooperative transaction data in the supply chain process, and solves the contradiction between the privacy of supply chain transaction data and the implementation of supervision. The application designs two verification methods of transaction types based on an aggregated signature protocol, so as to realize aggregated verification of on-chain transactions and rapid tracking of abnormal transactions, and effectively improves the performance of system supervision and traceability.

The application discloses a kind of methods and systems for developing custom software by CAE simulation APP, belong to software development technical field.The method includes: determining the parameters required by design engineer in each simulation App in target industry, to generate the part unit corresponding to each simulation App;Using test case, the correctness of the metadata in each simulation App corresponding part unit is checked, to build the part unit library corresponding to the target industry;Using the functional requirements of industry-specific software and part unit library, part unit screening is carried out to combine part units;The combined part unit is packed as industry-specific software.The application can reduce the development workload and cost (i.e. manpower and time) of industry-specific software, the development speed of industry-specific software is fast, the efficiency of developing industry software is high, and the data transmission and interaction between each simulation App in the development process of industry-specific software are guaranteed.
