Representation of real-time decision-making by contextual graphs based simulation

Abstract

An important aspect of mobile decision is its temporal nature. Experts develop a decision-making process jointly with the progressive elaboration of a context-specific model of the decision-making. However, context modeling is generally not considered explicitly, because only the result of the decision-making process is supposed to be of interest. For mobile decision, modeling this contextualization process supposes a formalism allowing a uniform representation of knowledge, reasoning and contexts like the Contextual-Graphs formalism in which all the contextual variants of a decision-making process are represented as a contextual graph. This paper presents the example of a workflow manager that is developed in a large project in breast cancer diagnosis. The workflow manager is a real-time decision-making process in which the result of an action may change the context of the decision-making process. Managing context jointly with the decision-making process is a way to tackle time and model effectively mobile decision-making.
