Technology, Complexity, and Risk: Social systems analysis of risky socio-technical systems and the likelihood of accidents

this article conceptualizes the multi-dimensional "human factor" in risky technology systems and cases of accidents. a social systems theory is applied to the analysis of hazardous technology and socio-technical systems, their complex dynamics, and risky dimensions. the "human factor" is often vaguely identified as a risk factor in hazardous socio-technical systems, particularly when accidents occur. but it is usually viewed more or less as a "black box", under-specified and under-analyzed. three key aims of the article are: (1) to identify and theorize in a systematic way the multi-dimensional character of the "human factor" in risky systems and accidents; (2) to enable the systematic application of a substantial social science knowledge to the regulation of hazardous systems, their managers and operatives as well as regulators, especially relating to the "human factor;" (3) to serve as an guiding tool for researchers and regulators in the collection and organization of data on human and other factors in risky systems and accidents. in sum, the article proposes a systematic approach to analyzing many of the diverse human risk factors associated with complex technologies and socio-technical systems, thus contributing knowledge toward preventing - or minimizing the likelihood of - accidents or catastrophes.
