Chapter 15Integrating Human and Organizational Factorsinto the BCD Risk Analysis Model: AnInfluence Diagram-based Approach ¹

 

 

 

15.1. Introduction

With technological advances and the complexity of industrial systems, it is necessary to examine security in these systems also considering their human operators. As such, the study or analysis of risk in industrial systems has developed over recent years. Initial research into risk analysis has focused more on considering technical aspects, but this has resulted in an increase in serious incidents (such as the nuclear disaster in Chernobyl in 1986 and the 1984 Bhopal disaster). This has, therefore, highlighted the need to develop an integrated risk analysis approach considering technical, environmental, human, and organizational aspects together.

In this section, we examine research carried out within the SOMAIR Project¹ that aims to provide a detailed study of human factors in risk analysis based on research (undertaken by project partners EDF Energy and CRAN²) into integrated risk analysis [LÉG 09, LÉG 08] and research into analyzing human aspects in a human–machine system, particularly within the framework of the benefit-cost-deficit (BCD) model by another project partner, LAMIH³ [POL 09, PAC 07, ROB 04, VAN 11]. The different partners in the project have a common scientific interest, notably in the evaluation of ways of limiting risks, i.e. barriers that are a means of avoiding the occurrence of a serious incident and limiting ...
