Software Issues – Prof. SalimSoftware Issues – Prof. Salim

•Have just obtained GIS network integrator. This will be used for networking snowplow routes.

•In process of developing better lab network interface with UNIComputer support staff.

•In process of developing needed CD burn-in facilities andsoftware for final project distribution.

Snow Removal Asset/Resource Snow Removal Asset/Resource Management SystemManagement System

General prototype. Focus on integration of AI shell with GIS and databases

Use current information of DOT available through WWW

Simple rules for:– Priority assignment of segments of roads, based on

interstate condition, truck route, high or low traffic volume (based on Aadt of 5000 and 2000 respectively)

– Assignment of snow plower based on cost and capacity criteria for each priority

– Requires a hierarchy of rules to provide correct results (non monotonic logic)



May be easily extended to include new knowledge, restrictions, and other assets

Can include Cases for learning on CBR engine Uses 6 rules, 350 objects, 24 functions/routines, 8

databases for input, and generates 2 databases

Development of the PrototypeDevelopment of the Prototype Implemented using Rapid Development Cycle method

adapted for AI steps.

2 different programming languages: –ArtScript from Art Enterprise (Lisp-like). Implements logic and part of database analysis–Avenue from ArcView (VB-like). Graphic representation and data preparation for Expert System shell
