Hence, easier and more effective production control can be achieved. The information acquired includes the duration of each operation, the number of manufactured items of products, the amount of scrap as well as the duration of downtimes and their root-causes. A way to acquire relevant data makes use of special-purpose information terminals. The problem that arises here is how to select the optimum number ofthe terminals in order to minimize the overall losses. The approach presented below relies on optimization of a stochastic criterion function, which combines the terminal costs and costs related to the waiting times during busy sessions. The solution suggested is based on using the distribution of events, recorded during the past production session. A case study dealing with optimum selection of terminals in a real production processis presented in detailCilj avtomatiziranega zbiranja podatkov v kosovnih industrijah je zagotoviti čim bolj točne podatke o opravljenem delu z namenom doseganja učinkovitega in kakovostnega upravljanja proizvodnje. Podatki se nanašajo na čase, porabljene na posameznih opravilih delovnega naloga, stevilo izdelanih kosov, količina izmeta in vzroki za izmet, vrste zastojev, njihovo trajanje in vzrok. Eden od načinov zbiranja podatkov iz proizvodnje vključuje njihovo beleženje preko informacijskih terminalov. Problem, ki se pri tem pojavlja je kako optimalno razporediti terminale tako, da so čakalni časi za vnos podatkov čim manjši. Prispevek obravnava pristop, ki sloni na optimizaciji naključne kriterijske funkcije, ki združuje stroške nabave terminalov in stroške zaradi čakalnih časov pri vnašanju proizvodnih podatkov. Ideja rešitve temelji na uporabi statistike dogodkov na proizvodni črti, ki je prevzeta iz zgodovine postopkaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
