Place change driven software update method and apparatus, and readable storage medium

A place change driven software update system for updating a software architecture SA, comprising:

• an evolution rule matching module, configured to:
• model the software architecture SA and a corresponding evolution rule set L⇒R through Bigraph, wherein the evolution rule set is a conversion process from one subgraph of the Bigraph to another subgraph of the Bigraph;
• acquire a software architecture SAt after movement and before evolution of the software architecture SA;
• compute a place ΔP that changes between the SA and the SAt;
• and acquire a place set {ΔP1, ΔP2, . . . , ΔPn} for all change places in the corresponding evolution rule set L⇒R;
• and
• determine whether the place ΔP belongs to the place set {ΔP1, ΔP2, . . . , ΔPn}, and end the method if no, or otherwise, acquire a corresponding matching place ΔPJ of the place ΔP, thereby acquiring a corresponding evolution rule Lj→Rj;
• a place graph and link graph replacement module, configured to:
• respectively compute a place graph LjP and a link graph LjL according to the Lj, respectively compute a place graph SAP and a link graph SAL according to the software architecture SA, acquire a matching subgraph GP of the place graph LjL in the place graph SAP, and acquire a matching subgraph GL of the link graph LjL in the link graph SAL;
• and
• respectively compute a place graph RjP and a link graph RjL according to the Rj, respectively cut the matching subgraph GP on the place graph SAP with an isomorphically cutboundary cluster and replace with the place graph RjP to obtain a new SA place graph SAP,e, and cut the matching subgraph GL on the link graph SAL and replace with the link graph RjL to obtain a new SA link graph SAL,e;
• and
• a software update module, configured to:
• merge the new SA place graph SAP,e and the new SA link graph SAL,e to obtain an evolved software architecture SAe, thereby implementing update of the software architecture SA,
• wherein the evolution rule matching module, the place graph and link graph replacement module, and the software update module are executed by a processor of the place change driven software update system.
