Cascading failure tolerance of manufacturing services collaboration network toward industrial internet platforms

Manufacturing services provided by distributed enterprises are integrated via industrial Internet platforms and collaboratively complete the personalized tasks submitted by platform users. Those collaborating services form a manufacturing services collaboration network (MSC-Net), with the collaborative services as nodes, and the collaborative relationships between them as edges. The uncertain failure of a node/edge cascading propagates to its dependent nodes/edges and causes cascading failure, eventually triggering task interruptions or even global collapse, seriously affecting the reliable operation of industrial Internet platforms. In view of the above problems, a cascading failure tolerance (CFT) approach based on the network cascade effect for MSC-Net is proposed. In which, considering the basic network structures, failures and their cascading propagation occurred in the complex network community–based MSC-Net are detected and traced, and a network cascade effect–based CFT mechanism is designed accordingly based on the load redistribution, service supplement/replacement, and local reconstruction. Experimental results show the feasibility and effectiveness of the proposed methods.
