This checklist covers categories of decisions, decision-making processes, types of decision support systems and artificial intelligence systems, and selecting the appropriate IT system. It includes decision types, decision support systems components, group decision support systems, geographic information systems, and artificial intelligence types such as expert systems, neural networks, genetic algorithms, and intelligent agents.

4 Decision Supportand Artificial Intelligence
Knowledge Workers Checklist must understand: • categories of decisions & the process of decision making • types of decision support systems & their roles • types of artificial intelligence systems & uses • how to the choose the appropriate IT system
find what to fix find fixes pick a fix apply the fix Decisions • Types • structured vs. unstructured • recurring vs. ad hoc • Decision making steps • intelligence • design • choice • implementation
Decision Support Systems (DSS) • a computerized system to help you make decisions • components • data management • model management • user interface management
Group Decision Support System (GDSS) • used in team problem solving • components • special groupware • DSS capabilities • telecommunications
GDSS Decision Process • brainstorming • issue categorization and analysis • ranking and voting
Meeting Types • synchronous • same room • same city • same planet • asynchronous • same city • same planet
Geographic Information Systems • a DSS for spatial (map) information • applications such as: • targeting customers by area • planning routes of a truck fleet • planning marketing campaigns
Artificial Intelligence - AI • machines imitating human thinking and behavior • types • expert systems • neural networks • genetic algorithms • intelligent agents
Expert System applies reasoning to reach a conclusion
Good for • auditing • diagnosing engine problems • production problems • lithographic printing
Components of Expert Systems • information • people • IT components
Information Types • domain expertise • how to solve the problem • why? Information • answers users questions • problem facts • particulars about current problem
People • domain expert • person who knows how to solve problem • knowledge engineer • IT specialist • knowledge worker or user
IT Components • knowledge base • knowledge acquisition component • inference engine • user interface • explanation module
Neural Network learns to differentiate patterns on its own
Good for • finding fraud in credit card use • reading handwriting • finding anomalies in human tissue
Training a Neural Network • show the neural network lots of examples • tell it which category each belongs to • with practice, the neural network can distinguish categories by itself
Genetic Algorithm uses the evolutionary, survival-of-the fittest process to find the best solutions
Good for • finding cheapest route for laying cable • finding best stock portfolio combinations
Genetic Algorithm Concepts • selection • give preference to better outcomes • crossover • combine portions of good outcomes • mutation • randomly try combinations
Intelligent Agent performs repetitive tasks on a computer or network
Types • find-and-retrieve agents • buyer agent or shopping bot • user agents • check e-mail • monitoring and surveillance agents • monitor network for likely problems • data-mining agents • data warehouses
Summary • decisions come in several types • decision making consists of intelligence, design, choice and implementation • Decision Support Systems (DSS) are computerized systems that can help people make decisions • a Group DSS can be used to make meetings more efficient and effective • Geographic Information Systems (GIS) is a type of DSS that handles spatial information • Artificial Intelligence (AI) is used to make machines think and or behave like humans • AI types - expert systems, neural networks, genetic algorithms, intelligent agents
