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.

Web applications are widely used on the Internet and Intranets. They are easy to be provided because a provider does not have to deploy them to each client. Accordingly, screen transition diagram (STD) is used to analyze the requirements of Web applications quickly. STD is useful to grasp the outline of the whole application, but analysts in most cases draw the diagrams from the scratch, even if they contain similar functionalities. This paper addresses a case-based design framework for supporting to draw STD of Web applications. In this framework, the analysts would combine different parts of STD over multiple Web applications, by dividing STDs into Web Page Transition Groups (WPTGs) based on the exchanged data among the screens. Moreover, a search support method to find appropriate WPTGs is considered in the framework.
