Outline of Final Research Achievements

Open systems such as Web applications may fall into undesirable situations by unpredictable behavior of users or clients. The situations are such that the system is functionally correct, but exhibits behavior different from what the system owner expect from it. Such faulty behavior is not a program bug that must be removed, and is called “Soft Faults”here. This research project proposes a general theory to account for the Soft Faults, and shows that the theory is effective by applying it to a self-adaptive Web application system.
