Service Orientation of Environment Control Processes

Abstract

The paper introduces a framework for designing flexible Environment Control Services (EServices) based on generic sensing, modelling and control process specifications allowing the customization of distributed Facility Environment Control Systems (HFES) in holonic approach. The representation, assessment, configuring and implementation of these EServices by the interacting holons using data structures models in different perspectives their type, features, functionalities, interdependencies and usage: (i) the EService Type perspective used to identify a requested type of service included in an existing service-ontology; (ii) the EService Specification perspective allowing the client (the environment conditioning application) to define the facility’s environment needs as service properties; (iii) the EService Profile perspective in which the resources publish their capabilities matching the requested EService Type, exposing them to (iv) the EService Configuring and Implementation perspective. In the resulting Service-oriented HFES (SoHFES), four types of processes: environment monitoring, control, conditioning and production influencing, represented in the service perspective either as simple or composite services according to timing progression, granularity and concurrency of their operations can be standardized into EServices which allows for flexibility, agility, robustness and reusability of control solutions. A generic design framework and experimental results are finally presented.
