DYNAMIC LIQUIDATION GROUP FORMATION AND LOCAL REGENERATION METHOD AND SYSTEM BASED ON HETEROGENEOUS PARTICIPANT CONTRIBUTION CONSTRAINTS IN LIABILITY GRADINGS

Abstract

The invention relates to a computer-implemented method and system that creates a dynamic liquidation group from participants linked only by genuine liability relationships within a directional source graph formed from verified liabilities. The contribution ratio / amount parameters of the participants are converted into machine-implementable contribution capacities. For each linked candidate subgraph, the target liquidation value X, the total contribution Q, and the coverage ratio ?=Q / X are calculated; only candidates satisfying the condition ??1 are considered applicable. In the case of a common ratio, the required minimum number of contribution positions is determined by m=?1 / r?, and in heterogeneous ratios, it is determined according to the total contribution capacity. In case of a change in source registration or contribution, only the affected applicability region is locally re-derived. The contributions of the selected group are locked, the necessary approvals are obtained, and the candidate liquidation status is created.Once connectivity, coverage, contribution limits, approvals, and releases have been verified, contribution transfers and approved liability status updates are enabled in a controlled or atomic manner.
