N2 - In Probabilistic Risk Assessment (PRA), the temporal dimension has been improved, and is currently being explicitly considered in simulation-based techniques. However, the spatial dimension is only being considered implicitly in Fault Trees and Event Trees through functional models. Human Reliability Analysis (HRA) does not explicitly consider spatial dimensions of Performance Shaping Factors, except for man-machine interface, which is only partially considered in human error estimations. The Socio-Technical Risk Analysis (SoTeRiA)framework was developed to incorporate organizational factors into HRA and PRA. This paper reports on the initial stage of research to advance the dimensions of space and time in SoTeR1A. The paper reviews the dimensions of space and time in traditional engineering practices, social and organ izational theories, and in the existing risk analysis methods. It highlights the theoretical and methodological perspectives on the incorporation of spatio-remporal dimensions in SoTeRiA. The ultimate results of this research will help (1) identify the underlying socio-technical root causes offailures associated with locations and space, (2) quantify the spatio-temporal organizational failure mechanisms by integrating a Geographic Information System (GIS)-based modeling platform with PRA, and (3) advance quantfication and visualization ofsocio-technical risk scenarios that will enhance risk-informed decision making applications (e.g., Emergency Response Modeling).
