Product development simulation with multicriteria analysis
Tomaž Kostanjevec, Andrej Polajnar, Metka Kostanjevec, 2009, izvirni znanstveni članek

Opis: Effective product development rests on a productćs design ability to create a positive product experience. This involves complex transformation of product information from customers to engineers to production to sales and back to customers. This work presents the concept of simulating the development of a new product. The multicriteria analysis of product development in a multi-dimensional space is being used. Based on simulation, the model shows in which direction the product will be developed on the basis of existing information. In the set multi-dimensional space, in which each observation parameter has a designated polar dimensional in terms of dependence on time, development on the basis of selected products is simulated. In an innovative way and in the case of sanitary fittings, simulation of the development of a new product in the early stages of design ideas is shown.

Energy saving and modifications in the methanol process, using the NLP model optimization
Anita Kovač Kralj, Peter Glavič, 2006, objavljeni znanstveni prispevek na konferenci

Opis: The opportunities for additional profit depend very much on the existing plant and energy system. Heat and power integration can reduce fuel usage in chemical processes. Nonlinear programming contains equations which enable structural and parametric optimization. The NLP model is formulated using an optimum energy target of process integration and electricity generation using a gas turbine with separator. The reactor acts as a combustion chamber of the gas turbine plant, producing a lot of energy. The simultaneous NLP approach can account for capital cost, integration of combined heat and power, process modification and additional production of trade-offs, and can thus yield a better solution. The combined production of electricity, heat and chemical products can lead to better process efficiency. The methanol plant was optimized using a mathematical nonlinear programming model by including an additional flowrate of hydrogen in crude methanol recycle and increasing the methanol production by 2,5%. The electricity can be generated in methanol recycle using a gas turbine. The total additional profit is 2,5 MEUR/a.

Intelligent support to specific design aspects
Urška Sancin, Jasmin Kaljun, Bojan Dolšak, 2008, izvirni znanstveni članek

Opis: Due to increased rivalry on the market, some specific design aspects like the use of modern plastics materials, ergonomics and aesthetics are becoming more important and are not kept in the background any more in correlation with functionality and economic aspect of the product. Design engineer faces many dilemmas while designing new products as a single person is not able to possess a wide spectrum of knowledge needed for optimal design solutions. At this point designer have to rely on his or her experience and on the knowledge of the expert team involved in the project. The fundamental purpose of the research presented in this paper is to make the product development process less experience dependent. The main goal of thematically oriented research is to develop intelligent advisory system with integrated modules forsome specific design aspects.

Product development through multi-criteria analysis
Tomaž Kostanjevec, Andrej Polajnar, Andrej Sarjaš, 2008, izvirni znanstveni članek

Opis: The trend regarding the development of sanitary fittings is forecasted by the use of a developed model of multi-criteria analysis. In this analysis a multi-dimensional space is used, which enables the establishment of a time argument in comparison to product parameters. The establishment of product parameters is achieved by means of internal company information and market needs. In this way it is possible to establish an innovative environment for the development of new products. This paper indicates various ways of dealing with product development, on the basis of which the method of multi-criteria analysis for establishing future trends in product development is acquired.

Analysis of product development on large-scale production with multi-criteria approach
Tomaž Kostanjevec, Jože Balič, Matej Rajh, 2009, izvirni znanstveni članek

Opis: The multi-criteria (MC) method is applied to the development of a large-scale product in the case of mid-price range washing machines using MC approach. The concept represents the method for developing a new product in the production process. The development of a large-scale product on the basis of MC analysis provides more accurate forecasting of the most important parameters in the centrefold of a multidimensional (MD) character in the way of customer demands, and important production and development restrictions areset in this MD environment with aid of MC analysis. The production parameters are identified and through this, there is a possibility of reducing production costs. A forecasting method of production demands as possible result is powerful tool for achieving strategically and concurrent advantage.

Product lifecycle management with knowledge management as a strategic approach for innovative enterprise environment
Valentina 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.
