2. A spatial decision support system for traffic accident prevention in different weather conditionsDanijel Ivajnšič, David Pintarič, Jaša Veno Grujić, Igor Žiberna, 2021, izvirni znanstveni članek Opis: Natural conditions play an important role as determinants and cocreators of the spatiotemporal road traffic accident Hot Spot footprint; however, none of the modern commercial, or open-source, navigation systems currently provides it for the driver. Our findings, based on a spatiotemporal database recording 11 years of traffic accidents in Slovenia, proved that different weather conditions yield distinct spatial patterns of dangerous road segments. All potentially dangerous road segments were identified and incorporated into a mobile spatial decision support system (SLOCrashInfo), which raises awareness among drivers who are entering or leaving the predefined danger zones on the street network. It is expected that such systems could potentially increase road traffic safety in the future.

4. Towards a virtual product modelAndrej Tibaut, Danijel Rebolj, 2003, izvirni znanstveni članek Opis: Today, many researchers working on the information management process in construction recognise the problem of modelling complex product-related data structures. Furthermore, many experts doubt whether an all-inclusive-product-model is a solution for an integrated information environment that should efficiently support the life cycle of a product. It seems that rich experiences in product modelling gathered during the last decade do not necessarily lead to better models but rather to the awareness the more complex the product models are, the more rgid and less usable they become in practice. The paper first summarises some deficiencies of complex product models and then introduces a new conceptual solution, called "virtual product model", which is based on the on the decomposition of a conventional product model. The concept investigates the dissharmony in the structure and semantics of distributed (virtual) parts by applying agent technology and then the tuple space communication model.

5. A model of data flow in lower CIM levelsIgor Drstvenšek, Ivo Pahole, Jože Balič, 2004, izvirni znanstveni članek Opis: After years of work in fields of computer-integrated manufacturing (CIM), flexible manufacturing systems (FMS), and evolutionary optimisation techniques, several models of production automation were developed in our laboratories. The last model pools the discoveries that proved their effectiveness in the past models. It is based on the idea of five levels CIM hierarchy where the technological database (TDB) represents a backbone of the system. Further on the idea of work operation determination by an analyse of the production system is taken out of a model for FMS control system, and finally the approach to the optimisation of production is supported by the results of evolutionary based techniques such as genetic algorithms and genetic programming.

6. Databases for technological information systemsFranc Čuš, Bogomir Muršec, 2004, izvirni znanstveni članek Opis: Organization of tool management for mixed production includes today, in particular, the computer-supported management and organization of the flow of tools and data on them. The system supports the entire flow of tools in a production process including the tool store management, commissioning, mounting, dismantling and pre-setting of tools. The system contains the management of the tool database with all vital data on tools and ensures adaption of production requirements for meeting the needs for tools. The integral model for the selection of optimal cutting conditions in the computer aided tool management system (TOMS) is proposed. The integration of technological databases and tool management systems is urgently necessary. The target function for the OPTIS programme, worked out by the programme package Microsoft Visual Basic, is selection of optimal cutting conditions from commercial databases with respect to the lowest costs of machining by taking into account the technological limitations of the metal removal process. The newly developed OPTIS programme selects optimal cutting conditions with respect to the tool maker, workpiece material, type of machining, cutting machine, smallest and greatest cutting conditions, tool, data on series, type of clamping and workpiece geometry.

7. A model of simulation environment for prediction and optimisation of production processesIgor Drstvenšek, Mirko Ficko, Ivo Pahole, Jože Balič, 2004, izvirni znanstveni članek Opis: Paper describes means and methods for computer based optimisation of production processes using a new approach based on technological database (TDB) with genetic algorithm incorporated into a database management system (DBMS). The TDB serves as a store of tools and machine tools from which they can be assigned to different work operations. Work operations are basic entities of orders placed into queues. The goal of the model is to find available resources from the TDB in order to empty the queue in shortest time with lowest costs. To this purpose the model consist the technological database whose DBMS includes a genetic algorithm based optimiser. It checks the orders queue and searches for appropriate combinations of tools and machine tools from the TDB, which can be combined into needed work operations. It also performs an optimisation of time and costs according to so called static parameters of tools and machine tools.
