And it introduced access rules and fuzzy time constraint mechanism and the role of system modules and method of binding system modules and the role achieve the goals.

The Maximum Flow Problem with Fuzzy Constraints;

The Minimum cost Flow Problem with Fuzzy Constraint;

The fuzzy reliability and fuzzy constraint were introduced in the reliability optimum design of laminated composites.

According to the principle of fuzzy optimization, a mathematical mode of mechanical structure with fuzzy constraints was built, so the fuzzy optimum problem was transformed into the ordinary optimum problem combining with finite element method.

The infeasibility problem in voltage/reactive power optimization is analyzed in this paper, and this problem is handled with fuzzy constraints to obtain a solution as close as possible to the original space.

The interaction balance method with fuzzy constraints is proposed for steady state large-scale industrial processes under steady-state optimization with the consideration of the model-reality difference problem and the constraints of processes being of flexibility.

With transformation of the color space, a new effective fuzzy clustering based on fuzzy restraint two dimension histogram is presented for color elements segmentation.

The robustness problem of fuzzy restriction conditions was analyzed, and it was pointed out that the fuzzy restriction condition in general fuzzy optimal design didn′t have feasible robustness.

Based on the principle of robust design, the robustness rule of fuzzy restriction condition in tolerance type was put forward.
