In data processing, fuzzy math make fuzzy things into the mathematical model and makes full use of the intermediary transition information, It can reduce the impact of man-made subjective factors and makes the assessment results more objective and reliable, which can be used in equipment support exercise assessment.
Multi-level evaluation: Synthesize each first-level factor’s fuzzy evaluation result in the new fuzzy evaluation matrixand multiply it with the corresponding weighting vectorresult in the fuzzy evaluation vector of the overall evaluation factor, that is the fuzzy evaluation vector of the total capability of the equipment support exercise: (2) The reduction probability of integrated electronic information system corresponds to the elements in vector, and the final exercise level can be achieved according to the principle of maximum subjection.

Fig. 3 The dependence of the bending stress in the pin (1) and the couplings (2) with a round and shouldered (3) profiles of the thread on the pre-impact speed of the striker The reduction of the tangential stresses in the pin and the coupling when the rod is stricken is due to the fact that when a pulse compression passes through the communication unit, the turns of the pin or the coupling are unloaded from the static axial force.

One of the advantages of this pressing technique is significant simplification, reduction of specific quantity of metal, and the cost of process equipment [1, 2, 3, 4, 5, 6, 7, 8, 9].
Comparison of experimental data (1) with mathematical modelling (2) for AMg6M material, r = 2 mm, S = 2 mm; z = 2,1 mm: а) dependence between the springing angle and the edge exceeding (relative settlement of polyurethane - 20%); b) dependence between the springing angle and the relative settlement of polyurethane (= 2,1 mm) Based on this work, it can be concluded that the constrained bend process with elastomer mathematical model generally demonstrates good convergence with the experimental results within the range of researched material billets and their type and size.
