Decision Analysis Using the Benefit-Cost-Deficit model

In this paper, we are interested in the decision analysis focusing on the Benefit-Cost-Deficit (BCD) model. The BCD model is proposed recently in order to analyse the intentional deviated users behaviour (prescribed behaviour crossing). This later is considered as a decision problem under risk where the consequences of users’ decisions can be evaluated following three attributes: the Benefit, the Cost and the Deficit. This paper proposes to consider the context of the decision, so we extend the BCD model by introducing different organizational and human factors that influence the users in their actions. This means that the deviation of users behaviour is not only related to their voluntary and intention but also to other factors, such as those of the organization of the system that has also some objectives to achieve as improving production and quality. To build the decision model based on the BCD approach, we propose a graphical representation using influence diagrams. The advantage of the proposed framework is to analyse the users’ decisions in terms of benefit or risk considering the context (as the organisational factors).
