Descripción
Networks of mutual collaborative systems present unique challenges of representation (e.g. which model) and analysis (e.g. which quantities) that are not easy to be addressed without a comprehensive modelling framework. In many cases, specialization prevails in several current approaches to the problem, which can be of topologic nature, behavioural nature, organizational and so forth. Each aspect of the problem brings its specific modelling languages and analysis tools. On top of this, each particular sector adds additional specialized elements. For example, communication networks, power grids and gas pipelines present their own approach and language that fit their analysis requirements, but cannot be applied to other sectors. This work defines a modelling framework that makes it possible to address resilience of complex and heterogeneous networked systems. The model is heterarchical and crosssectorial, in order to broaden as much as possible the scope of application. Relationships and interdependencies among the components are expressed at functional level. Interdependencies are derived by transforming the model into a ?goal dependency structure? that helps to trace causes, propagations and consequences of a malfunction. Scenarios that differ from the expected nominal conditions are systematically derived by exploring this structure. The undesired events are here combined with the system response, which represents the ability to face/resist to different threats in a resilient fashion. The generated scenarios are called ?resilience scenarios? and, once identified, they can be further analysed by system analysis, simulation, or reproduced by experimental testbeds, if applicable. Several elements of this work are original contributions, like the language itself, the goal dependency structure and the associated resilience analysis. The availability of a systematic cross-sector methodology also provides guidelines for the analyst who, in this way, will be able to proceed from a solid basis, instead of resorting to ad-hoc notations and approaches. The proposed modelling framework is not specifically addressed to system design, rather it is intended to support decision making and may be integrated into a (traditional) risk assessment framework for networked infrastructures.
