IMPACT OF ICT SUPPORT, LEADERSHIP AND QUALITY ON SUSTAINABILITY AND BUSINESS EXCELLENCE

A problem of Business Excellence (BE) has been investigated according to different aspects. For more detailed analysis it is necessary to develop an integrative model of business excellence, respecting baseline model of business excellence according to European Foundation of Quality Management (EFQM), with possibility to define relationships and level of significance of different variables. The main goal of the paper is to develop an integrative model for simulation effects in order to improve the ICT support, quality and leadership as independent variables on business excellence (BE). The model has been developed using techniques of modelling complex dynamic systems and evaluated using statistical techniques. In the sample of 159 organization in Serbian ICT support, leadership and quality and their impact on BE have been analysed. After analysis of simulation, it had been concluded that it is possible to improve business excellence with relative small investment in ICT support, leadership and quality.https://jibi.aspur.rs/archive/v1/n1/1.phpPublishe

Smanjenje troškova proizvodnje regeneracijom zaptivnih elemenata

Kod mašina za izradu gumenih mešavina vremenom dolazi do habanja zaptivnih elemenata. Zaptivne elemente čine dvodelni prstenovi i čaure, čiji je zadatak da obezbede zaptivanje između komore i rotora miksera. Dodirne površine prstenova i čaura su u neposrednom kontaktu, tako da pri radu mašine dolazi do habanja ovih zaptivnih elemenata. Kontaktne površine moraju da poseduju visoka antihabajuća svojstva i visok kvalitet obrađene površine, a potrebno je vršiti i podmazivanje odgovarajućim uljem kako bi se habanje svelo na najmanju moguću meru U ovom radu je izvršena analiza uticaja postupka regeneracije ovih zaptivnih elemenata na troškove proizvodnje. Konkretno, analiziran je uticaj kontaktnih površina na kojima se nalazi stelit (originalni prstenovi i čaure), površina regenerisanih tvrdom elektrodom i površina regenerisanih specijalnom aluminijumsko - kalajnom bronzom, na troškove proizvodnje.Publishe

LEAN PROIZVODNJA - POLAZ ZA USPEŠNU PRIMENU

U periodu posle 1990. godine širom sveta je primetna tranzicija sa sistema serijske ili masovne proizvodnje na integrisane proizvodne sisteme. Shvatajudi potencijal integrisanih proizvodnih sistema kod kojih se ostvaruju smanjeni troškovi izbegavanjem otpada mnoga preduzeda slede primer Toyota-e i pokušavaju da poboljšaju performanse svojih proizvodnih sistema primenjivanjem koncepata i metoda Lean proizvodnje. Koncept Lean proizvodnje nudi strategiju kojom se eliminiše otpad, postiže visoki kvalitet procesa i proizvoda i smanjuje vreme koje je potrebno da se novi proizvod nađe na tržištu. Ovakav koncept je uspešno primenjen kod velikih preduzeda dok se mala i srednja preduzeda susredu sa problemima kada pokušavaju da inplementiraju koncepte i metode Lean proizvodnje. To je prouzrokovano različitim efektima Lean metoda na proizvodnju u zavisnosti od uslova u proizvodnji koji se odnose na različitost proizvoda i njihove količine, varijacije procesa, vremena trajanja procesa itd. S obzirom da u Srbiji gotovo da ne postoji preduzede koje koristi prednosti koncepta Lean proizvodnje ovaj rad predstavlja kratki pregled istorijata nastanka Lean proizvodnje, njenih osnovnih ciljeva i principa i tehnika i alata koji se pri tome koriste kao i pregled najznačajnije literature koja se bavi ovom tematikom.Publishe
