Abstract
EN The objective of this work has been to propose a framework that will aid governments with the development of more coherent and effective infrastructure planning and resilience policies through a system-of-systems approach that is grounded in theory for complex sociotechnical systems. The framework has been developed by using a work domain analysis (WDA). The WDA consists of an abstraction hierarchy analysis and a part-whole decomposition. Together, the abstraction hierarchy and the part-whole description form the abstraction-decomposition space (ADS) for which the system constraints apply. By imposing constraints, the WDA promotes design for adaptation where actors within the system are allowed to adapt their behaviour as they find appropriate without violating the system’s constraints. The proposed ADS consists of five levels of abstraction and four levels of decomposition. By applying the ADS, it will aid decision making related to the overall purposes of the critical infrastructure system, the values and priority measures that are used to assess the system’s progress towards the functional purposes, as well as formulation of infrastructure needs that are necessary to achieve the functional purposes. The framework is formative in the sense that it reveals how work can be done in the critical infrastructure system. This is important because it is not feasible to prescribe, describe and risk assess all possibilities for action that are available in complex sociotechnical systems, especially when dealing with unforeseen events. Future research should focus on finding science-based yet useful in practice ways for establishing values and priority measures that encompass sustainability issues and resilience standards.
