The application provides a big data-based intelligent manufacturing supply chain management system and method. A cloud big data engine is used to jointly model supplier capacity, logistics timeliness and historical abnormal events based on multi-source data flow of a manufacturing supply chain, and generate a risk probability matrix of material shortage in multiple supply chain nodes. When the risk probability of material shortage of a supply chain node exceeds a material shortage threshold, a risk decision is made on the risk probability matrix and the work-in-process cache amount as a joint state space, with the goal of minimizing total interruption cost and maximizing delivery rate, and a material shortage scheduling scheme of the manufacturing supply chain is output. The material shortage scheduling scheme is distributed to corresponding suppliers and logistics parties through a blockchain smart contract, and order splitting and payment binding are automatically executed to complete the material shortage scheduling of the supply chain. Based on the above scheme, multi-objective autonomous scheduling of material shortage risk of the manufacturing supply chain can be realized, thereby improving the anti-disturbance capability of the manufacturing supply chain under interruption environment.

This invention relates to a method for extrapolating transient measurements from a Gordon heat flux meter, comprising two main steps: pre-test calibration and post-test data processing. The pre-test calibration process uses laser or other means to test the heat flux meter and obtain key parameters such as the output coefficient and response time. The post-test data processing mainly includes steps such as data pre-pruning, data pre-fitting, data linearization, nonlinear point removal, data fitting, and steady-state heat flux prediction. By introducing this invention, steady-state heat flux parameters can be predicted even before the heat flux meter's output parameters have stabilized.

Compared to other data extrapolation methods, this application fully considers the actual physical model of the heat flux meter and combines statistical methods to efficiently and with high confidence extrapolate the range of the true heat flux.
