Decision Support Systems

Using a DSS involves four basic types of modeling activities: What-if Analysisan end user makes changes to variables, or relationships among variables, and observes the resulting changes in the value of other variables Sensitivitiy Analysisa special case of what-if analysis—the value of only one variable is changed repeatedly, and the resulting changes on other variables are observed. Goal Seeking Analysissets a target value for a variable and then repeatedly changes other variables until the target value is achieved Optimization Analysisthe goal is to find the optimum value for one or more target variables, given certain constraints
