Preliminary notesToday's business of manufacturing systems is entirely dictated by the dynamics of the market and every day there is a need for adjustment of the structure and parameters of associated manufacturing systems. Those adjustments should ensure the operation of manufacturing systems in more favourable manufacturing and economic conditions, and often this process is directly linked with the starting of investment process. On the other hand, every day practice proves that evaluation of investment program during selection of structure of manufacturing system with the aim to accomplish production plans and reduction of production costs is often based on insufficient sets of information. Lack of information may result in inappropriate insight into overall techno-economic effects that can be achieved by investment program. Within this paper are presented researches which resulted in development of a new systematic approach in the analysis of potential structures and parameters of manufacturing systems with the aim to plan, project or reengineer manufacturing systems on the basis of minimal production costs.Keywords: equipment structure; investments; material flow; manufacturing system; production costs; simulation Utjecaj strukture proizvodnog sustava i opsega investicije na troškove proizvodnjePrethodno priopćenje Poslovanje današnjih proizvodnih sustava u potpunosti je diktirano dinamikom tržišta te se svakodnevno javlja potreba za prilagodbom strukture i parametara proizvodnog sustava kako bi se poslovalo u što povoljnijim tehnološkim i ekonomskim uvjetima, a nerijetko je ovaj process vezan i s ulaskom u investicijski postupak. S druge strane, praksa dokazuje da je ocjena investicijskog programa pri odabiru strukture proizvodnog sustava u cilju ostvarenja planirane proizvodnje i smanjenja troškova proizvodnje često zasnovana na nedovoljnom skupu informacija, tako da se ne dobiva relevantna slika o tehno-ekonomskim efektima koji će biti posljedica investicijskog programa. U okviru članka prikazani su rezultati istraživanja koji su doveli do razvoja metodičkog pristupa analize mogućih struktura i parametara proizvodnog sustava u cilju planiranja, projektiranja ili reinženjeringa proizvodnog sustava na bazi minimalizacije troškova proizvodnje.
