Developing and implementing applications using service computing is the current mainstream technology and plays an important role in large-scale network collaborative applications. Problems such as the disconnect between business and IT implementation, and the poor adaptability of services to business changes are the main obstacles to large-scale software development and implementation. The essence is that the core business requirements are difficult to express, verification is not easy, and dynamic mapping and management are unsatisfactory. In response to these problems, the project team established a "service integration platform based on process model" to achieve the on-demand goal of application software systems and external environments in a network computing environment. Aiming at the integration and reuse requirements of resources in the enterprise environment, the platform starts from model interaction analysis and uses business processes to drive the analysis, modeling, management, encapsulation, verification, testing, application and other processes of business component models to realize the interoperability and integration of information, processes, services and other components, and constructs a service-based configurable flexible platform to realize on-demand construction and evolutionable response of network application software. Its main innovations include: (1) An on-demand support framework for business services for the full life cycle: With model interaction as the core, a formal representation model is established, and business modeling, service transformation, system configuration, testing and verification, service governance based on metamodel are established. The framework implements model-driven information architecture generation and dynamic evolution to realize an on-demand aggregation process based on business requirements and constructs an integrated platform for the design, development, configuration, and operation of professional application services. (2) Information fusion and sharing based on multi-view business models: Based on the multi-view business model, it provides a reference standard for heterogeneous and multi-source information fusion and exchange, and then realizes multi-mode data fusion based on variable-granularity combination and multi-granularity decomposition., constructs a stateless service interoperability mechanism, realizes flexible processing and flexible configuration of information, and establishes a model foundation for large-scale service processing. (3) Service integration automation mechanism based on formal model: Through software formal representation based on process model, a process-oriented interactive capability description is constructed, and then the configuration process of service description, transformation, collaboration, and integration is realized. A rule-based service composition framework implements a service composition method oriented to service quality assurance. An adaptive random testing method based on differences is established to realize a model-driven service integration, an automated environment for verification and testing, and a model-driven software service construction, assembly, integration, implementation and application realization are constructed. (4) Service dynamic cooperation mechanism based on operation feedback: Service-oriented continuous governance uses service monitoring to realize evaluation and recommendation of service dynamic quality, and establishes evaluation and recommendation algorithms for service dynamic quality to realize service dynamic cooperation mechanism. Dynamic integration of heterogeneous services and scalable resource configuration for cloud-oriented environments provide an implementation approach, support adaptive dynamic evolution of system operation, and provide technical realization for innovative development and application models of cloud-end integration. The platform achieves integrated service full life cycle support, has high degree of automation and strong reusability, shortens the software development and implementation period, and meets the needs of practical applications of enterprises. It has obtained 4 invention patents, 7 software copyrights, and more than 50 papers, including 50 SCI/EI searches, and the main technical effects of the project have generally reached the international advanced level. The platform has been applied to many companies in the medical IoT, design and manufacturing, transportation and logistics and other industries. According to incomplete statistics, the application of this project has generated direct economic benefits of 47.66 million yuan and indirect benefits of 65.28 million yuan, with obvious economic and social benefits. The project realizes the organic integration and interaction of business strategies and IT architecture, provides a support carrier for the integration of industry informatization and industrialization, can help enterprises quickly respond to the external environment, and has good development prospects and promotion value.
