Study Notes
Analytical Techniques
- Unstructured problems are best suited for heuristic approaches and simulation models
- Heuristic approaches are typically used for problems that cannot be solved using optimization techniques
Optimization Techniques
- Genetic algorithms do not guarantee an optimal solution to a problem
- Blind search differs from optimization in that it does not use heuristics or evaluation functions
- An optimal solution is understood as the best solution among all possible solutions
- Complete enumeration of solutions is used when the problem size is small
Simulation Models
- 'What-if' models are most typically used for scenario planning and predicting outcomes
- Simulation models are not desirable for problems that can be solved in one pass without iterations
- Steady-state plant control design uses steady-state simulation
- Decision makers cannot change the underlying dynamics of the system in a simulation
Advanced Modeling Techniques
- Discrete events and agent-based models are not suitable for modeling continuous systems
- Visual interactive simulation (VIS) is a modeling technique that allows users to interact with the simulation model
- Visual interactive modeling (VIM) systems are developed for 'thinking' characters in the entertainment industry
Case Study
- The Canadian pandemic case study used a macro-level simulation model to predict the spread of the pandemic
Location-Based Analytics
- Real-time marketing promotion is a type of location-based analytics
- GPS Navigation is an example of location-based analytics
- Teradata's data warehouse has a new geometric data type that captures geospatial features
- Path Intelligence's system is used to ascertain how people move within a city or store
Content-Based Filtering
- Content-based filtering uses detailed information about item characteristics to restrict the process to a single user
Service-Oriented DSS
- Service-oriented DSS is not characterized by a user interface
- The business process component of service-oriented DSS optimizes the DSS environment use by organizing its capabilities and knowledge into business processes
- Data-as-a-Service (DaaS) platforms are a type of service-oriented DSS
- The business data component of service-oriented DSS describes the meaning and structure of business data
- The SOA (Service-Oriented Architecture) platform offers a flexible data integration based on service-oriented standards enabling ubiquitous access to any type of data
Decision Support Systems
- When new analytics applications affect multiple related processes and departments, the organization is best served by utilizing an enterprise-wide approach
- Research into managerial use of DSS and expert systems found that decision makers do not use DSS to replace human judgment
