Later we will analyse how to rank investments and how to select the tangible investment portfolios when the magnitudes are estimated subjectively by comparing fuzzy numbers and with possibilistic mathematical programming. <\/jats:p>","DOI":"10.1142\/s0218488503002077","type":"journal-article","created":{"date-parts":[[2003,10,16]],"date-time":"2003-10-16T10:47:26Z","timestamp":1066301246000},"page":"263-281","source":"Crossref","is-referenced-by-count":26,"title":["Using Fuzzy Set Theory to Analyse Investments  and Select Portfolios of Tangible Investments in Uncertain Environments"],"prefix":"10.1142","volume":"11","author":[{"given":"Antonio","family":"Terce\u00f1o","sequence":"first","affiliation":[{"name":"Department of Management,  University Rovira i Virgili, Av. de la Universitat,  l.
