The UK is one of these countries in Europe, which have the highest death rate from asthma, and the rules to identify asthma control steps are vague in the current official guideline of asthma management. In this research, diagnosis rules on asthma control steps are developed to supplement the current guideline and to assist patients to monitor and manage their asthma on daily basis. The main challenge...
Uncertainty is inherent in almost any project and complex system, and aircraft maintenance is not an exception. During its execution, unexpected damage, failures and discrepancies may be found, which must be corrected by programming unscheduled tasks. However, due to the stochastic nature of these unforeseen events, it is difficult to plan unscheduled activities and then to estimate the resources...
The evidential reasoning (ER) approach was developed to support multiple criteria decision analysis (MCDA). It is based on the Dampster's combination rule for criteria aggregation and belief function for treating ignorance. In the original ER approach, however, alternative ranking depends on the accurate estimation of a value function, which may be difficult in certain decision environments. In this...
In engineering practice, a system's behavior constantly changes over time. To predict the behavior of a complex engineering system, a model can be built and trained using historical data. This paper addresses the forecasting problems with a belief rule base (BRB) to trace and predict system performance in a more interpretable and transparent way. More precisely, it extends the BRB method to handle...
The basic theory of the evidential reasoning (ER) approach is firstly introduced. Since many uncertainties and ambiguities are included in a variety of real decision making problems, accurate number is not competent for the description of the assessment value any more. Some ER models in the circumstance of interval belief degrees or interval weights are then proposed by some people. The analytical...
