The KAPSARC Toolkit for Behavioral Analysis (KTAB) is not a model, but rather a platform for building models: it is a Collective Decision-Making Process (CDMP) simulator that can generate insight into policy decision making. This platform is designed to enable a broader range of analysts to generate their own insights, but we hope its release will extend the awareness of computer models as a route to the investigation of CDMPs.

CDMPs are processes in which a group of actors interact to arrive at a joint decision. In both general and technical parlance, CDMPs may be termed bargaining or negotiating. We adopt the term CDMP to avoid confusion with legacy interpretations of these words, but the general meaning remains the same. The deliberations of a corporate board, the internal debates of ruling parties, the voting of electorates, and the haggling between seller and buyer at a market stall can all be viewed as CDMPs, albeit with different actors operating according to different rules. KTAB is intended to support reasonable analysis of the potential outcomes of CDMPs involving a range of modeled groups. In any group, the actors hold different values, positions, and views, which they bring to the CDMP.

KTAB has been developed as modular libraries of code to enable analysts and computer programmers to construct their own models of CDMPs, secure in the knowledge that their approach is theoretically sound. These are already available for free download at
