Fuzzy multiple level programming

The use of fuzzy set concept to overcome the computational difficulties of multi-level optimization for large systems appears to be a powerful approach and can solve practical large problems in a very simplified manner. Furthermore, unlike the due-ploy or multi-ploy approaches, the proposed interactive concept provides flexibility, which is essential due to the different styles of management in different organizations. The approach is formulated based on exploring the fuzziness or indefiniteness, which is almost always present in a decentralized large hierarchy organization. The advantage of this approach is that not only the problem is much more simplified for solution purposes, the original problem is also much more realistically represented.
