Multi-Criteria Analysis

Another possibility is the application of multi criteria analysis (MCA). Basically the MCA is based on a matrix in which the different alternative (clusters of) measures are the columns and the different criteria that are used to evaluate the alternative measures are in the rows. One may vary the weights of the different criteria, (via desk research but also interactively in workshops with stakeholders), and see what happens with the preferential sequence of the alternatives. MCA is a method that does not require a full quantification of all effects but it makes transparent which alternatives are to be preferred when using certain criteria. Of course there has to be agreement between the decision makers on the criteria and the weights that will be used.


 
In all cases it is imperative to gain insight in the system that has to be influenced, not only from a technical point of view but also from a societal (socio-economic point of view)
 
Measures with respect to priority substances will often be part of the WFD and bear relations with other substances, stakeholders etc. That is why it is very important to look at the system as a whole and to treat the problem of priority substances as part of a wider problem field, including its stake holders and decision makers. Selection methods will of course only be useful if a selection has to be made between alternatives. So there must be more than one “solution" and the measures must in principle be feasible in a technical, social, economic and juridical way.
In whatever situation as a minimum requirement the reduction of concentrations and the costs of compliance have to be calculated / estimated. The definition of costs and benefits may be different for economists, engineers, policy makers and other stakeholders. In the further development and application of the DSS we will try to develop a common vocabulary. Use will be made of earlier experiences, or experiences else where (e.g. REACHexternal link, opens in new window etc).
