UNCERTANITIES AND RISK IN GEOLOGICAL ACTIVITIES AND NEW WAYS OF THEIR HANDLING
Journal Title: UNKNOWN - Year 2001, Vol 13, Issue 1
Abstract
The authors rewiev the main types of uncertainties occuring in connection with geological investigations. The general concept of handling these uncertainties are outlined. The particular features of scalar, spatial and spatial-temporal evaluations are presented. Limitations of the traditional mathematical approach – deterministic and probabilistic – applied to geological investigations are discused. In the second part of the paper nem mathematical methods are presented that are more suitable to handle uncertaintes that the traditional ones.The fuzzy set theory seems to be one of the most efficient for geological purposes, among these methods. The problems of uncertainty in risk analysis are shortly discussed. Finally, results of test calculations performed by fuzzy arithmetic are presented.

IOR AND EOR – CHANCES FOR INCREASE OF OIL PRODUCTION AND RECOVERIES IN EXISTING, MATURE RESERVOIRS
After the application of conventional oil extraction techniques, about 2/3 of discovered reserves still remain to be produced. In view of high probability for oil presence and oil price increases, investments in resea...
RAZINE SELENA I TEŠKIH METALA U POVRĆU I TKIVIMA TRIJU PTICA STANARICA IZLOŽENIH TLU, VODI I RIJEČNIM SEDIMENTIMA ONEČIŠĆENIMA SELENOZNIM RAŠKIM UGLJENOM
Rudarenjem i spaljivanjem ugljena u okoliš se ispuštaju onečišćivala koja se tamo zadrže desetljećima. Rad donosi podatke o koncentraciji Se i teških metala (As, Cd, Cu, Cr, Hg, Pb, Sr, U, V i Zn) u salati, krumpiru i tk...
MOGUĆNOST OPLEMENJIVANJA KVARCNIH PIJESAKA HRVATSKIH LEŽIŠTA PRIMJENOM MEHANIČKOG ATRICIJSKOG ČIŠĆENJA
Da bi se dobila kvarcna sirovina koja svojom kvalitetom udovoljava specifičnim zahtjevima pojedinih industrija, rovni pijesak mora proći odgovarajući proces oplemenjivanja. Mogućnost dobivanja koncentrata kvarcnog pij...
TUNEL LAVE LEIðARENDI
Island je po mnogoþemu fascinantan dio Zemlje. Izvana je prekriven snijegom i ledom (kako mu i samo ime govori) te okružen morem, a iznutra užaren (odatle i boje na zastavi Islanda: bijela, plava i crvena). U usporedb...
Srebreni putevi u Europi početkom novog vijeka i rudarsko-financijski imperiji Fuggerovih
Znatan uvoz plemenitih kovina (zlata i srebra) i predmeta načinjenih iz njih, nakon otkrića Amerike, u Europu izazvao je u Europi "srebrenu groznicu", pa je ubrzana eksploatacija već otkrivenih nalazišta srebrene rude, a...
