Models ofconsensus are used in the validation process to develop a basis for system performance. This paper develops two analytic models ofconsensus that can be useful in the validation process. The first model employs the binomial model to study the probability that the consensus judgment is correct or incorrect. This problem is critical for the validation of expert systems, since the model le...

The Wettelijk Beoordelingsinstrumentarium (WBI) is the legal set of instruments for flood risk analysis in Netherlands. Often, engineers have impression that some failure probabilities defenses resulting from these are overestimated. In an effort to better estimate dikes along Dutch river Rhine, this study sets out assess them with experts and compare model results. We used Cooke’s method combi...

Expert-based estimation is the most common and preferred method to estimate the effort for software development project because it is fast, less expensive and reasonably accuracy. Expert software developers use his intuition and experience during effort estimation task. Estimation by analogy of features is also used to compare the new feature to similar in past development. This paper extends r...
