  Cross-Impact Balance Analysis (CIB) is a widely used method to build
scenarios and help researchers to formulate policies in different fields, such
as management sciences and social sciences. During the development of the CIB
method over the years, some derivative methods were developed to expand its
application scope, including a method called dynamic CIB. However, the workflow
of dynamic CIB is relatively complex. In this article, we provide another
approach to extend CIB in multiple timespans based on the concept 'scenario
weight' and simplify the workflow to bring convenience to the policy makers.
