MODEL BASED ANALYSIS AND CONTROL OF A REAL-WORLD SYSTEM

A method for the analysis, based on a computer model of a real-world system whose entities are represented by software objects (artefacts) for: risks of real-world events occurring (risk artefacts); actions in the real-world system (action artefacts), associated with tasks, resources and conditions; and in which a subset of the model is represented by a system context. The method comprises defining actions required to accomplish a target task, thereby allocating resources to actions; computing a manageability index of the at least one system context, representing an extent to which resources are available; computing a feasibility index of the at least one system context, representing an extent to which actions are possible; computing an aggregated risk of the at least one system context; creating and displaying, on a display device, a visual representation of the aggregated risk, the manageability index and the feasibility index of the at least one system context.
