User Interface for Sensitivity Analysis on Qualitative and Quantitative Hybrid Simulation

The qualitative and quantitative hybrid simulation system was proposed for support of designing a business scenario. In using the system, a business manager must describe a qualitative and quantitative hybrid model for the simulation, and perform sensitivity analysis to decide appropriate input values. Those are complicated tasks, so that a business manager often spends time. In order to support those tasks, we propose user interfaces that consist of a model description editor and a visualization window of changes in input values and output values for sensitivity analysis. A model description editor makes it easier to describe the hybrid model by interactive editing the model represented as a graph. A visualization window expresses changes in input values as a radar chart and plots averages and variances of changed output values for comparison. As a result of questionnaires concerning the user interface, it is confirmed that our proposed interface is effective for designing a business scenario.
