MCDA web app released

26 Jul 2013 — Gert van Valkenhoef

We have just released the first version (0.1) of our web based multiple criteria decision analysis (MCDA) preference elicitation tool. This component will be used in ADDIS 2.0 to support benefit-risk decisions. It is currently available online at mcda.clinici.co.

You will need a recent browser; we recommend Mozilla Firefox or Google Chrome. Several examples are provided. You can also load your own benefit-risk assessments by exporting them from ADDIS 1.16.4 (released last week). We would be glad to hear your feedback.

ADDIS status and future

19 Mar 2013 — Gert van Valkenhoef

The ADDIS 1.x software has been very successful as a prototype, and our decision to develop it as a desktop application has allowed us to focus on essential problems in evidence synthesis and decision analysis. However, the ADDIS vision can not be fully realized in a single user environment. The ADDIS 1.x retrospective provides an overview of design decisions made for ADDIS 1.x and their positive and negative consequences. It also identifies key changes that need to be made going forward.

The ADDIS 2.x requirements and architecture document summarizes the long-term vision and current status of ADDIS, identifies key requirements and proposes an architecture for ADDIS 2.x. Note that this document is focused on architecturally relevant non-functional requirements rather than on specific functional requirements (such as the types of analyses that should be supported). We're currently hiring new developers (updated 2013-04-26) to start implementing the new architecture.
