Chapter 1 Systems Analysis of the Urban Planning Processes 6
City as a General System External influences Steering subsystem Decision making and planning Input Informational subsystem Controlled subsystem Information system for city-wide management and planning Output 7
Main sources Strategic information coming from the steering subsystem Information coming from measures on the controlled subsystem Urban information system Information for decision making and planning 8
Decision support systems Decision-Support Systems Based on Operations Research Based on Document Navigation - data analysis - system modelling - search strategies - optimization - multi-criteria - content analysis - documentation archiving - search strategies - browsing - controllability - relevant information 9
