Open image in new window Fig. 2 Qualitative model formulation and the Bayesian network model.
The case study is carried out is three steps comprising incident analysis, qualitative model formulation and sensitivity analysis [17].
At this stage, a qualitative model formulation is first established based on literature review and consultation with MTR operators, engineers and maintenance staff.
The background of the collected incidents is introduced in the Incident Analysis step; a qualitative model formulation is established based on functions in the DMOM analysis and relationship analysis among these functions in the second step and an importance model and sensitivity analysis model are presented in the last step.
The effect was pronounced enough to allow drawing conclusions on qualitative relation between formulation and properties of the composite friction material.
In qualitative reasoning, model formulation is the process of moving from the unruly, broad set of concepts used in everyday life to a concise, formal vocabulary of abstractions, assumptions, causal relationships, and models that support problem-solving.
The study of equilibrium problems ((operatorname{EP})), which was introduced by Blum and Oettli [11] in 1994, in terms of their formulation, qualitative analysis, and computation has been the focus of much research in the past several decades and has given rise to the development of a variety of mathematical methodologies.
This allows formulation of qualitative rules and enables simulations where complex qualitative dynamic behaviours can be generated in computationally efficient models representing molecular activities by a few discrete states.
Although this study emphasis on qualitative research for the formulation of key concepts and operationalization; another important requirement is the availability of a requisite data, and it is rather problematic in general for the formulation of key concepts and operationalization, a second requirement is the availability of a requisite data, and this is still rather problematic in general.
Major inter-provincial differences in POA dispensing levels and qualitative patterns of POA formulations dispensed persisted.
