|Several systems have been developed for assessing/analyzing risks in
the construction industry. The majority of them are tailored toward a specific
situation, activity, or, in some cases, certain company conditions. Lack
of compatibility among these systems has dimensioned their benefits. In
addition, most of these systems do not allow concurrent input from several
users, something that is usually needed in several situations. This paper
presents an object oriented framework designed to act as a core for further
specific risk analysis systems. The system has five major modules: user
interface, user analysis, input analysis, fuzzification, and thread modules.
By creating instances of these modules, systems tailored for specific purpose
can be developed. Having the same root and the same data structures and
interfaces, such systems will be compatible. In the proposed framework,
a risk issue is projected as the combination of several smaller risky elements.
Each risk element is presented in five dimensions: possibility, probability,
importance, dependency, and inheritance. Elements are then arranged into
a series of risk threads whose combined effect produces the final output.
Different concurrent users can collaborate in assessing different threads.
