Six Sigma is a method of management that strives for near perfection. The Six Sigma methodology uses data and rigorous, statistical analysis to identify defects in a process or product, reduce ...variability and achieve as close to zero defects as possible. The paper presents the basic information on this methodology.
This paper focuses on the assessment of possibilities to subsidize the purchase and installation of solar collectors in Poland by government or local government grants and special funds designed for ...this purpose. It analysis of costs and profits resulting from the application of solar installations in the process of heat generation for household requirements, by calculating the payback time, with taking into account prices of other energy carriers and the above mentioned subsidies. Collectors at present are manufactured solely from metals (copper, aluminium, Al-Mg alloys). The use of these materials is tied to considerable energy demand and the production technology is complex. This affects the economy of running a solar device.
Članak je usmjeren na procjenu mogućnosti novčane potpore nabavke instalacija solarnih kolektora u Poljskoj od vlade ili lokalnih pokrovitelja te posebni fondovi utemeljeni u tu svrhu. Analizirani su ...troškovi i dobit kao rezultat primjene solarnih instalacija u procesima zagrijavanja po zahtjevima, proračuna povratka investicije, uzimajući u obzir cijene računa ostalih, tj. više drugih usporednih energija. Sadašnji kolektori ustrojeni su od metala (bakra, aluminija, Al-Mg legure). Rabljenje ovih materijala je u svezi energetskim zahtjevima i proizvodnom tehnologijom. Utjecaji ekonomije ovisni su o solarnim uređajima.
The field of quality is very important for a company under current conditions. It is necessary to continuously improve the quality of provided services. Even though metallurgy is focused on ...production, not on providing services, even in these companies great variety of services exists, which is important to improve all the time. One of these production supporting services are the repairs. This article analyses and solves the problem of insufficient promptness of the repairs in a metallurgy company.
Six sigma je metoda menangmenta koja se približava savršenosti. Ova metodologija rabi podatke i oštru statističku analizu na identifikaciji grešaka u procesima ili proizvodima, s ciljem snižavanja ...varijabli, te dostići nultu razinu grešaka. Članak daje temeljni očevid na ovu metodu.
The present article intends to asses returns on shares of the steel companies that were formed based on either merger or acquisition. The analysis included 14 operations in the steel industry. ...Attention was paid to returns of the companies performing acquisitions, as well as to the returns on shares that presented the acquisition target. The analysis was performed based on the “event study” method, and the analysed event was the announcement or notification of realization of an acquisition. Shares of the target steel companies as well as acquirers are attaining higher returns, but the change was not statistical significant.
U suvremenim uvjetima poslovanja područje kvalitete vrlo je važno za kompaniju. Neophodno je kontinuirano poboljšanje kvalitete pružanih usluga. Iako su metalurške kompanije fokusirane na proizvodnju ...u njima postoje velik broj različitih usluga koje je potrebno unaprjeđivati cijelo vrijeme poslovanja. Jedna od tih usluga koje podupiru proizvodnju je održavanje. U članku se analizira i daje rješenje problema nedovoljno brze reakcije službe održavanja u metalurškim kompanijama.
