1. As a part of a TUBITAK project, a researcher has been working on a disaster management system by employing Cognitive Mapping method. Once a set of criteria are identified, Cognitive Map is drawn as follows. However, only a part of the proposed map composed of six variables (thereafter will be called as C1-C6 for the sake of simplicity) is illustrated. Based on the positive and negative relations among criteria as on the map, construct Valency Matrix, Vj matrices, and obtain Reachability matrix. C1 C5 C2 C6 C3 + C4
