This study sets immune theory as breakthrough points, introduces immune theory into organizational quality management scope with a view to evaluating and enhancing organizational quality specific immune maturity symmetrically and permanently. This study establishes an evaluation index system of organizational quality specific immune maturity and constructs a quality specific immune maturity evaluation and decision-making model based on an immune perspective. Further we used symmetrical methods of a continuous interval number median operator and multiple attribute decision making to carry out empirical analysis. The median idea is introduced, and the points in the 1/2 position of the basic interval monotone function are selected in evaluation and decision-making calculation by continuous interval number medium operator method. Empirical analysis research can avoid the influence of extreme value, provide new ideas and methods for effective evaluation and decision making of organizational quality specific immune maturity. The outcomes of this study have important practical significance for enhancing organizational quality specific immune maturity of equipment manufacturing enterprises.
As the starting point, the immunity theory is introduced into the organization quality management, combined with the organization quality specific immunity system, the evaluation index system of organization quality specific immunity is designed. And the evaluation and multi-attribute group decision making model of organization quality specific immunity based on the immunity perspective is constructed by the method of multi-attribute group decision making of intuitive pure linguistic aggregation operators, empirical analysis is carried out by the research objects of relevant experts, representative and typical manufacturing enterprises, the empirical analysis results indicate that multi-attribute group decision making method of intuitive pure linguistic aggregation operators can choose and determine the optimization evaluation solution and the best decision making of partners, confirm the highest value over all partners for organization quality specific immunity system, the method of multi-attribute group decision making of intuitive pure linguistic aggregation operators has validity, feasibility and operability in evaluation and decision making of organization quality specific immunity. Empirical analysis results and conclusion have certain practical value, which provide new ideas to solve the problem of multi-attribute decision making of intuitive information mixed with pure linguistic information, and provides the basis for the effective selection of the best partners for manufacturing enterprises of the supply chain from the perspective of quality management.
Given a measurable function λ with λ ∞ < 1, the approximating solutions of Beltrami equation for λ are directly constructed by using the techniques of SG circle pattern and conformal welding. It is proved that the sequence of approximating solutions converges uniformly on to compact subsets to a quasiconformal mapping with complex dilation λ. This provides a new approach of constructing discrete quasiconformal mappings.
