3.2 Decision support module
The decision support module consists of two models which
are risk analysis and workflow formulation. The risk analysis
model is developed using AHP, while the workflow
formulation model is designed using the CBR technique.
In the risk analysis model, the identified potential risk factors
are categorized and presented in a hierarchical structure. The
risk factors are then assessed through pair-wise comparison,
according to the likelihood of occurrence and
consequence/severity, as collected from the questionnaire.
The mark is rated in accordance with a nine point scale to
show the importance of the risk factor and its sub-risk factor.
Table 1 shows the description of nine point scale for
weighting the likelihood and consequence/severity, with
