Abstract

A qualitative simulation system has been developed for understanding the behavior of a system modeled by a structural model. In decision making, it is necessary to understand the influence flow, namely how the model derives the behavior of the concerning node in the model rather than the behavior of each node. This paper presents a mechanism of scenario generating for explaining the influence flow to the concerning node. The mechanism consists of the following processes: 1) by tracing the structural model, all paths from the input node, which triggers the initial change of the system, to the concerning node are derived, and using similarity of behavior, the influence flow to the concerning node is selected out of all paths; 2) important nodes are selected according to the type of nodes; and 3) the scenario document is generated along the selected flow using the sentence template and the word dictionary
