    This aim of paper is to presents the development of a multidisciplinary project carried out by the cooperation between Politecnico di Torino and ITHACA (Information Technology for Humanitarian Assistance, Cooperation and Action). The goal of the project was the training in geospatial data acquiring and processing for students attending Architecture and Engineering Courses, in order to start up a team of "volunteer mappers". Indeed, the project is aimed to document the environmental and built heritage subject to disaster; the purpose is to improve the capabilities of the actors involved in the activities connected in geospatial data collection, integration and sharing. The proposed area for testing the training activities is the Cinque Terre National Park, registered in the World Heritage List since 1997. The area was affected by flood on the 25th of October 2011. According to other international experiences, the group is expected to be active after emergencies in order to upgrade maps, using data acquired by typical geomatic methods and techniques such as terrestrial and aerial Lidar, close-range and aerial photogrammetry, topographic and GNSS instruments etc.; or by non conventional systems and instruments such us UAV, mobile mapping etc. The ultimate goal is to implement a WebGIS platform to share all the data collected with local authorities and the Civil Protectio

    Fuzzy real options valuation for oil investments

    Traditional valuation methods are less viable under uncertainty. Hence, other methods such as real options valuation models, which can minimize uncertainty, have become more important. In this study, the hybrid approach suggested by Carlsson and Fuller is examined for the case of discrete compounding as this approach better models risky cash flows. A new real options valuation model that will evaluate the investment in a more realistic way is suggested by postponing the defuzzification of parameters in early stages. The suggested model has been applied to the data of an oil field investment and in conclusion the loss of information caused by early‐defuzzification has been determined. Santrauka Tradiciniai vertinimo metodai yra mažiau patikimi esant neapibrėžtumams. Vadinasi, kiti metodai, tokie kaip realių pasirinkčių vertinimo modeliai, kurie gali minimizuoti neapibrėžtumus, tampa svarbesni. Šiame straipsnyje nagrinėjamas hibridinis Carlsson ir Fuller metodas, kuris buvo panaudotas diskrečiajam rizikingų pinigų srautų modeliavimui. Pasiūlytas naujas realių pasirinkčių vertinimo modelis, kuris realistiškiau įvertins investicijas, rodiklius apibūdinančią neapibrėžtą informaciją apdorojant ankstyvojoje stadijoje. Pasiūlytas modelis buvo pritaikytas investicijoms į naftos verslą modeliuoti, nustatytas informacijos nuostolis, kuris atsiranda dėl ankstyvo neapibrėžtų duomenų apdorojimo.
