Polish Academy of Sciences}, language={eng}, abstract={Planning topls have traditionally been built as oprimization models, as we intuitively find in some sense optimal plans easier to defend than loosely coupled ideas based on intuition and experience. Reality is, however, more compJex than that: optimization is based on the belief that we can trace and formulatc an internal logic which determines key elements of the planning problem. This internal logic is not always elear: some of its elements may be uncertain or imprecise, or we may miss some decisive clements. It may also be the case that a mathcmatical formulation of the inteval logic leaves out some essential qulllitative element.}, type={Text}, title={Methodology and applications of decision support systems : proceedings of the 3rd polish - finnish symposium, Gdańsk-Sobieszewo, september 26-29, 1988 * Interactive heuristics vs. optimization as planning strategies}, URL={http://www.rcin.org.pl/Content/205719/PDF/KS-1989-01-P04.pdf}, }
