Integrating facilities management information

Sammanfattning: The purpose of the study was to develop suitable information structures to sup port main processes of facilities management (FM). The approach chosen to create these structures was to develop a generic FM process model and a building product model. The research method used was a system analytical approach involving the definition of activity models and object-oriented conceptual schemas. The existing national construction classification system (the BSAB System) was an important point of departure in the research work.The resulting models were evaluated through prototyping. Three different prototypes were developed,: the Klara prototype (a system for plantring, operation and maintenance of building services systems), the Blandaren prototype (an object oriented database system for FM) and the Kronoberg prototype (a GIS like system for facilities management information). All the prototypes used data from real facilities. The prototype systems demonstrated that the product model @S-model) fulfils the requirements of flexibility, stability, adaptability, com prehensibility and cost-effectiveness, which are discussed in this thesis. The ge neric process model, which was mainly tested in one of the prototypes, should provide better conditions for integration by capturing main aspects of the es sence of FM and by providing an overall structure for information handling within FM.In parallel with the evaluation of the prototype work, a conceptual schema (the Spatial Arrangement Model) was developed. Tbis is based on experiences from the prototypes and done in collaboration with the standardisation work for building construction within the STEP (STandard for the Exchange of Product model data) activity.The overall result of the research provides basic prerequisites for the develop ment of commercial IT systems for FM as well as an input to international stan dardisation efforts
