Abstract
To develop a urban project there are three main phases:!.Problem definition and sizing phase:GIS.DB (Geographical Information Systems for Data Base), to be used to organise data as georeferenced Information;Quality Sheets, to be used for the definition of objectives and variables belonging to five class titles: static-protective; conceptual; technical-economical; social-environmental; subjective-non conceptual.Complexity Sheets, to be used to define the weight of each objective and to evaluate the expected utility (based on the standard gamble model); the evaluation of variables score in relation to the expected utility on local side as well as on the general side; the definition o f variables boundary to be considered. Evaluation Grid, to be used to define the value reference system and the evaluation criteria 2.Design phase:Integrated Matrix, to show variables/objectives interactions;DeSS.CT (Decision Support System by CT), to define a preliminary project;POV Compact Method, to follow the phenomenon development in a non-linear way;DeSS.ET (Decision Support System by ET), to develop the final project; GIS.MN (Geographical Information System for Management), a virtual geomodel finalised to the dynamic management of the project;SDSS (Spatial Decision Support System), an integrated georefenced system to join DSS and GIS functionalities. 3.Communication and sharing Information phase.Tool and support for the analogic communication, these are based on traditional implements also using advanced technologies;Tools and supports for digital communication are today available and allow a correct integration of all operators actions.
