    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
