The invention discloses a task assignment method for a multi-role employment mode, and relates to the technical field of intelligent scheduling, and the method comprises the following steps: building a responsibility chain topological structure, extracting cross-role responsibility elements according to a task target, task input, task output, a task preposition constraint and a task postposition constraint, generating a responsibility vector, and carrying out the task assignment of the multi-role employment mode. And a verifiable responsibility map is constructed. According to the method, a verifiable task responsibility chain is constructed, and responsibility
visualization, contract verifiability,
semantic alignment and
time sequence closed loop of the whole task disassembly and
handover process are realized through responsibility graph modeling and contract
fingerprint binding; the method combines consistency
verification and shadow path calculation, dynamically identifies and repairs the risk of chain breakage, improves the scheduling stability and the task execution credibility, and solves the problem that the breakage of the chain of responsibility is difficult to identify and repairs in the prior art.
