1. Intelligent process planning for competitive engineeringValentina Gečevska, Franc Čuš, 2010, izvirni znanstveni članek Opis: Process planning is one of the key activities for product design and manufacturing. The impact of process plans on all phases of product design and manufacture requires high level of interaction of different activities and close integration of them into a coherent system. This paper presents a process model of product development with manufacturing approach based on intelligent process planning techniques with focus on optimal selection of manufacturing parameters. Some derivations of the computing model for analysis of machining conditions by optimal determination of the cutting parameters in multi-pass NC machining activities are made with implementation of new evolutionary computation techniques. Genetic Algorithm (GA) based optimization method and deterministic optimization method (DO) are developed and then implementations into real manufacturing process planning for new product developed are analyzed. The results showed that both the developed optimization methods (GA and DO), especially GA, are effective methods for solving multi-objective optimization problems during the manufacturing process planning and cutting parameters selection.

2. Product lifecycle management with knowledge management as a strategic approach for innovative enterprise environmentValentina Gečevska, Borut Buchmeister, Zoran Anišić, Bojan Lalić, 2010, izvirni znanstveni članek Opis: Process planning knowledge (PPK) is one of the most important knowledge in production manufacturing enterprise. This paper analyzes the PPK and the concept of process planning information model (PPIM) implemented in production enterprise. In second part of the paper, there is done the basic information about PLM concept as a business strategy for product development where are included PPK and PPIM approaches, strategy which offer possibilities for innovation. Product Lifecycle Management (PLM) is the process of managing the whole life cycle of a product starting from generating an idea, concept description, business analyzes, product design, solution architecture and technical implementation, to the successful entrance to the market, service, maintenance and innovative product improvement.

3. 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.

4. The importance of the affective aspects in the planning of the goals of aesthetic educationOlga Denac, 2004, objavljeni znanstveni prispevek na konferenci Opis: The paper deals with the cognitive, affective and psychomotor aspects of the goals of aesthetic education in the theory and practice of pre-school and elementary school education. It points out the urge to account for the affective aspect in the formation of the goals of esthetic education. With this research, in which we also included pre-school teachers and those teaching the first grades of elementary school, we wished to produce an empirical study of the problems and particularities which emerge through direct planning of the educational goals of the cognitive, affective and the psychomotor domains and to determine the one which is predominant in the forming of the goals of education in music, arts and dance. The results of the research have shown that the predominant aspect or domain in the formation of educational goals, as far as the teachers were concerned, is the cognitive aspect before the affective and psychomotor ones. The teachers are on the one hand aware of the importance and the expedience of the affective and psychomotor aspects in the forming of goals in the field of esthetic education, yet they have not been considered to such an extent in practice.

5. Uvajanje računalniško podprte proizvodnjeUroš Trupej, 2013, diplomsko delo Opis: V svoji diplomski nalogi sem se osredotočil na uvajanje računalniško podprte proizvodnje in kakšne prednosti prinaša. Računalniško podprta proizvodnja združuje moderno računalniško tehnologijo z naprednimi obdelovalnimi stroji in povezavo z informacijskim sistemom, kjer je človek še vedno vodilo napredka. Na teoretičnem primeru sem prikazal kakšne spremembe mora neko podjetje opravit in kakšne pogoje mora zadostiti, da lahko uvede računalniško podprto proizvodnjo.

6. Intelligent design and optimization of machining fixturesDjordje Vukelić, Goran Šimunović, Branko Tadic, Borut Buchmeister, Tomislav Šarić, Nenad Simeunovic, 2016, izvirni znanstveni članek Opis: This work presents an integral system for machining fixture layout design and optimization. The optimization module of this system allows determination of optimal positions of locating and clamping elements, which provides required accuracy and surface quality, while at the same time guarantees design of collision-free fixtures. The design module performs selection of required fixture elements based on a set of predefined production rules. Adequate criteria for the selection of fixture elements are defined for locating, clamping, tool guiding, and tool adjustment elements, as well as for fixture body elements, connecting elements and add-on elements. The system uses geometry and feature workpiece characteristics, as well as the additional machining, and process planning information. It has been developed to accommodate machining processes of turning, drilling, milling, and grinding of rotational and prismatic workpieces. A segment of output results is also shown. Finally, conclusions are presented with directions for future investigation.

7. The impact of managers on successful ERP implementationFranc Ravnikar, 2010, izvirni znanstveni članek Opis: Lately, Enterprise Resource Planning (ERP) has been implemented in public organizations and organizations without competition in the marketplace. It is the ERP system that is almost as badly needed for the competitiveness and success of those organizations in the marketplace. The main reason lies in the fact that operating costs have to be reduced and the optimization of business processes is an option which nowadays is normally implemented together with new ERP. The success rate of ERP implementation remains very low with up to a 90% failure rate, as it is quoted in a lot of researches. Critical success factors (CSF) which influence successful ERP implementation are identical in all organizations. The main goal of this research is to find out the managers' impact on the critical success factors and thus their impact on the successful ERP implementation. Top management support is the most important critical success factor for successful ERP implementation, regardless of the fact whether the organization is on the market or not.
