Prozessorientiertes Facility Management in verteilten Umgebungen

The term Facility Management describes one part of business management with the goal of supporting the management activities through the delivery of infrastructure, technology and services. It covers the whole life cycle of a structural facility. An integration of facility management in the active processes of an enterprise or an enterprise group will be substantially supported by the introduction of an efficient, flexible and future-safe computer aided facility management system. But still no universal standards were established in this area. With high expenditure adapted single solutions are the rule, harm however the demand for a save investment independently of proprietary special solutions of individual manufacturers. An analysis of existing business standards shows that these solutions are suitable only partly for combining the existing isolated solutions in a virtual enterprise group in order to create a sustainable architectural approach for a process oriented facility management. In doing so the communication must not be reduced to pure data exchange, but only stable interface definitions and accurately specified document formats can lead to a continuous solution. In order to make these solutions for developers and end users in the phases of the design, the implementation and maintenance equally clear, a common vocabulary of concepts is necessary. The usage of the Unified Modeling Language gives thereby a promising basis. The concrete models with the contained types and their relations to each other are described over meta models. The usage of XML as means to data exchange between the individual components and for the description of the meta models guarantees a flexible and future-safe development basis. In the context of the work based on use cases the conception for a framework with core components for process oriented facility management in distributed environments is designed. The framework Simplix conceived by the author integrates meta models for the description of concrete data, workflow and access schemes. The designed modules are embedded into a component-based architecture, in order to obtain a greatest possible flexibility for the deployment in heterogeneous IT environments. The framework Simplix covers four core components. The SchemaService describes the concrete product models, the associated processes are represented by the WorkflowService. The realization of the access rules is realized by the SecurityService. The exchange of workflow messages with the encapsulated project data is done by the ExchangeService in XML. The presented design focuses on the integration of existing business and IT standards. The design of the four core components describes a possibility of standardization in the area of CAFM, which connects only the relevant data over processes detached from conventional export/import scenarios: <ul> <li>Reduction of the complexity of conventional product models by a standardization over meta models, the actual product and process models can be designed for end users and to their vocabulary of concepts adapted</li> <li>Support of the Ad-Hoc-manipulation of concrete product and process models, only thereby can be achieved an integration of different vocabulary of concepts</li> <li>The usage of standardized methods in the analysis and design phases makes a fast technical implementation of the individual services possible, especially during the integration of external software systems as always necessary in the CAFM sector</li> <li>Due to a clear interface specification external offers for individual services can be provided and used, the continuous use of XML makes an effective long-term data storage in a standardized, self-describing language possible</li></ul>
