Analytical modeling in DSS; MIS vs ESS
Short answer
Analytical modeling uses mathematical, statistical and logical models in a DSS for what-if analysis, sensitivity, optimization, forecasting and simulation. MIS serves middle managers with structured decisions and routine fixed reports. ESS serves executives with unstructured strategic decisions, interactive dashboards, drill-down, KPIs and external information.
Describe the role of Analytical Modeling in DSS. What are the differences between Management Information System (MIS) and Executive Support System (ESS)?
Role of analytical modeling in DSS
Analytical modeling means using mathematical, statistical and logical models to represent a decision problem and analyse alternatives. The model base is the core of a DSS.
Roles:
- Represent real situations in a simplified form (cost, demand, production models).
- What-if analysis - change inputs (price, demand) and see the effect on profit.
- Sensitivity and goal-seeking analysis - find which variable matters, or what input is needed for a target.
- Optimisation - linear programming for best resource use, transport or scheduling.
- Forecasting - regression, time series for sales or demand prediction.
- Simulation - Monte Carlo and risk analysis under uncertainty.
- Decision analysis - decision trees, ranking of alternatives, expected value.
- Reduce uncertainty and bias, giving consistent, faster and better-supported decisions.
Model types: financial, optimisation, simulation, statistical, forecasting.
MIS vs ESS
| Basis | MIS | ESS |
|---|---|---|
| Users | Middle managers | Senior executives |
| Decisions | Structured, operational/tactical | Unstructured, strategic |
| Output | Routine, fixed summary and exception reports | Graphical, interactive dashboards with drill-down |
| Data | Mostly internal | Internal plus external (market, competition) |
| Time horizon | Short to medium term | Long term |
| Detail | Moderately detailed | Highly summarised, with option to drill |
| Flexibility | Low | High, ad hoc |
| Analysis | Little | Trend, forecasting, KPIs |
| Example | Monthly sales report | CEO dashboard on market share |
