Why Study Decision Support Systems?
e-business models, they are investing in new data-driven decision support
application frameworks that help them
respond rapidly to changing market
conditions and customer needs
Trang 6Case #1: Centralized Business Intelligence
Strategic Business Intelligence Approach:
• Standardize on fewer business-intelligence tools
and make them available throughout
organizations even before projects are planned
• Create dedicated groups called competency
centers to manage business-intelligence
projects and provide technical and analytical
expertise to other employees

Case #3: Agent-Based Modeling for SCM
• In Proctor & Gamble’s computer simulations,
software agents represent the individual
components of the supply systems, such as
trucks, drivers, stores, and so on

rules that mimic actual behavior, such as,
“Dispatch this truck only when it is full”.
• The simulations let P&G perform what-if
analysis to test the impact of new logistics rules
on three key metrics: inventory levels,
transportation costs, and in-store-stock-outs.
