Generic Service

The purpose of this study is to define generic service processes, their system, and a scope of service science developed originally by the author. In the presented approach, the main criterion is the class of serviced users, since this leads to the six kinds of process recognition and eventually helps in planning e-service systems’ architecture. E-service system (e-SS) is defined as a mission-goal-strategy-driven configuration of technology, organizational processes and networks designed to deliver HTservicesTH that satisfy the needs, wants, or aspirations of customers. Marketing, operations, and global environment considerations have significant implications for the design of an e-service system. Four criteria which impact e-service systems’ architecture have been defined as: service business model, customer contact and level of involvement (Service User Interface), service provider’s enterprise complexity (Enterprise Systems and Networks), and scope of goods involved in service. It was proved that the e-service system is the intermediary layer between Service User Interface and Enterprise Systems and Networks. Two examples of e-SS have been modeled.

With the management refinement of heating supply, the district heating system deploys a large number of meters or sensors to monitor and control the operating status of the heating network. It often needs to process real-time streaming data and coordinate the related enterprise business systems to make low-latency, intelligent decisions on the changes of heating network in time. Therefore, the automatic collection, on-demand dissemination and fusion of real-time sensing data play an increasingly important role in district heating systems. This article proposed an event-driven SOA based district heating system architecture with complex event processing capability, which can easily support the on-demand dissemination and aggregation of monitoring information and realize the event-driven service coordination cross different service domains. Finally, a deployed District Heating Control and Information Service System (DHCISS) in Beijing validates the effectiveness of our approach.

Integrated Service

In IoT scenarios, numerous things and services are connected and coordinated via distributed events. Hence, a service bus needs to be established to streamline these events to enable the efficient and stable coordination of IoT services as an integrated service system. However, without an awareness of the coordination requirements of the application, the publish/subscribe-based service bus will not be optimally utilized to deliver real-time and coherent sensor events, and at the same time, service concurrency and scalability cannot be maximally realized. In this chapter, a service-oriented publish/subscribe middleware is proposed as a base for the construction of a distributed, ultra-scale, and elastic service bus for IoT applications. In order to establish this publish/subscribe service bus, the service coordination logic is then extracted from an event-driven business process, and the coordination logic is translated into the event matching and routing functions of the publish/subscribe middleware.

Although many IoT applications have been developed, a theoretical basis for interconnecting all things is still obscure. In order to establish a solid foundation for IoT applications, this chapter addresses three issues: how to model physical sensors and devices as IoT resources, how to introduce IoT resources into IoT services, and how to use distributed events to connect IoT resources and IoT services together to form an IoT service system. An IoT resource is defined by its static attributes and dynamic lifecycle; both of these are specified using semantic knowledge to enable automatic sharing and understanding. An IoT service is considered as a set of actions imposed on IoT resources to monitor and control the physical world. An example application is given in order to demonstrate a proof of concept for event-driven IoT services over IoT resources (streamlining events) to integrate IoT services.
