The main task is to modify the centralized form of service interaction ("orchestration") so as to exclude low-level details of the description of the interaction scenarios, while maintaining the rules of service interaction in the knowledge base. Unlike existing such systems, users do not need to have knowledge of the details of the interaction with the services and the availability of specific services, and therefore can create abstract computing scripts without special training. The idea of ​​"flexible orchestration" of web services using abstract formulations of computational problems on the basis of information from the knowledge base is investigated. The concept of software architecture of application systems has been developed, which provides for the possibility of abstract formulation of computational tasks without being tied to the details of interaction with computing resources and web services. The main architectural components of the solution that have been developed are: the client-facing tasking subsystem for the following subsystems; a computing execution subsystem that is the only entry point for computing tasks and includes a service registration and retrieval service that implements a multi-level knowledge base service search and a web services orchestration service to perform computational scenarios. Implemented a prototype of the application computing support system, which, unlike common workflow-systems, not only is able to execute a detailed plan of coordinated interaction of services, but also independently searches for services required for users' tasks in a registry built using ontologies.
