One of these decision making areas is supplier selection in e-procurement. Supplier selection is a multi-criteria decision making problem that deals with the optimization of conflicting objectives such as quality, cos...

We briefly introduce and discuss some criteria for optimal decisions. For the majority of this module, we consider a person’s utility for different options (or ‘rewards’ or ‘actions’) and, with uncertainty about the reward which will follow a specific decision, we aim at maximisation of the expected utility, which is actually the utility of the optimal decision (note that a decision is a gamble...

Compared to guideline representation formalisms, data and knowledge modeling for clinical guidelines is a relatively neglected area. Yet it has enormous impact on the format and expressiveness of decision criteria that can be written, on the inferences that can be made from patient data, on the ease with which guidelines can be formalized, and on the method of integrating guideline-based decisi...

In this paper we discuss a meta-model for the analysis and evaluation of collaborative modeling sessions. In the first part of the meta-model, we use an analysis framework which reveals a triad of rules, interactions and models. This framework, which is central in driving the modeling process, helps us look inside the modeling process with the aim of understanding it better. The second part of ...

This article presents a quantitative way of modeling the interim decisions of clinical trials. While statistical approaches tend to focus on the epistemic aspects of statistical monitoring rules, often overlooking ethical considerations, ethical approaches tend to neglect the key epistemic dimension. The proposal is a second-order decision-analytic framework. The framework provides means for re...

We review some experiences with multicriteria decision suppport systems (MCDSSs). We show that MCDSSs have been able to deal only with to the 'choice' phase of decision rather than with tasks involved in developing criteria and alternatives. This strongly limits the use of MCDSSs within organizations. Designers should focus their efforts on alternatives. This weakness of MCDSSs in dealing with ...
