Measurement of maintenance excellence

U održavanju je potrebno imati kvalificirane i obučene zaposlenike kako za uporabu suvremene opreme za održavanje, za defektažu i izvođenje radova održavanja tako i za primjenu suvremenih zahtijeva organizacije i menadžmenta. Zbog toga je potrebno redizajnirati procese održavanja na širi način od "klasičnog", koje se bazira na terotehnološkom konceptu. Uređenje održavanja treba se ostvarivati na istim suvremenim principima na kojima se zasniva postizanje poslovne izvrsnosti sustava u cjelini. To ujedno uključuje i poslovnu filozofiju koju čine procesni pristup projektiranja i rada, integrirani sustav menadžmenta baziran na primjeni određenih standarda (kvaliteta, životna sredina, sigurnost na radu i dr.) i elementima poslovne izvrsnosti. Izvrsnost održavanja predstavlja okvir za izazovan kritički osvrt na cjelovitost i produktivnost svakog poslovnog procesa ili projekta. Kroz izvrsnost održavanja, organizacija nastoji osigurati visoku kvalitetu procesa koji podržava kontinuirani napredak u funkciji održavanja i usmjerava se na različita područja kao što su strategije, zaposleni, informacije, rad i ostali poslovni aspekti održavanja.It is necessary for maintenance to have qualified and trained staff, capable of using modern equipment for maintenance, defect inspection and maintenance work, able of applying modern requirements of organization and management. Therefore, it is necessary to redesign the maintenance processes in a more extensive way than the classical, which is based on the terotechnological concept. Maintenance organization should be achieved at the same modern principles as the business excellence system of a company as a whole. This also includes a business philosophy that consists of the process approach to the design and operations of a company, an integrated management system based on the application of certain standards (quality, environment, safety at work, etc.) and elements of business excellence of a company. Maintenance excellence is a framework for a challenging and critical review of the integrity and productivity of any business process or project. Through maintenance excellence, any company seeks to provide a high quality process that supports continuous improvement focusing on various areas such as strategy, employees, information, work and other business aspects of maintenance

Influence of ambience temperature and operational-constructive parameters on landfill gas generation - Case study Novi Sad

Researches in the area of landfill gas generation and energy utilization are currently underway and widespread in the world for several reasons: reducing effects of greenhouse gases, possibilities for utilizing alternative energy sources, reducing conventional energy resources exploitation, and environmental protection. First part of this research is conducted with an aim to establish the influence of meteorological parameters, primarily ambience temperature, on the methane generation processes at Novi Sad landfill. The second part of the research refers to functional characteristics of landfill such as the waste age, closing practice, and the age of certain parts of landfill body, as well as the waste depth and quantity of generated methane. Based on several years of investigation, it is concluded that methane generation varies in the range of 0-34 vol. % m3/m3, and that seasonal variations have significant influence on methane generation. At low temperatures, during winter, methane generation and migration is stagnant while in summer periods, due to higher temperatures, the process of methane generation is more intensive
