Embodiment

[0044] 1 Establishment of user demand system and determination of importance for automatic sorting equipment

[0045] 1.1 Analytic Hierarchy Process

[0046] Analytical Hierarchy Process (AHP) is a hierarchical weight decision-making analysis method that applies network system theory and multi-objective comprehensive evaluation method, combines qualitative and quantitative methods to solve multi-objective complex problems.

[0047] The specific analysis and evaluation process is as follows:

[0048] (1) Establish a hierarchical structure model of customized user needs for automatic sorting equipment, which is divided into the first layer A, the second layer B and the third layer C;

[0049] (2) Compare user requirements layer by layer, judge the relative importance of elements in each layer, and construct a judgment matrix X=(x ij ) n×n .

[0050] (3) Use the square root method to calculate the eigenvector W and the largest eigenvalue λ of the judgment matrix X max . The c...

Abstract

The invention discloses a sorting equipment quality evaluation method based on AHP and QFD, which comprises the following steps: (1) establishing a sorting equipment customization demand system; (2) Analytic Hierarchy Process (AHP) is used to determine the weights of each user's needs; (3) determining the quality characteristics and their target values; (4) Introducing contrast equipment and evaluating by experts; (5) Construct the House of Quality (HOQ) by using the Quality Function Deployment (QFD) tool according to the results of the above steps; (6) According to the calculation results ofthe above steps, the market competitive ability and technical ability of the two sorting equipments are evaluated, and the improvement direction of the customized quality of the sorting equipments isput forward. Combined with AHP and QFD method, the invention can convert user requirements into design requirements, improve user satisfaction degree of personalized customization, and has strong operability and universality.

Description

technical field [0001] The invention belongs to the technical field of quality engineering, and in particular relates to a method for evaluating the quality of sorting equipment based on AHP and QFD. Background technique [0002] In the manufacturing process of modern enterprises, customer satisfaction has become the core goal of enterprise quality strategy and an important basis for quality design. With the diversification of user needs, the personalized customization model has gradually become the core competitiveness of manufacturing enterprises. Different approaches were applied around the issue of quality improvement in the design of individually tailored devices. [0003] In modern technology, aiming at the quantitative evaluation of the comprehensive ability of non-standard equipment manufacturers, the system analysis method is used to analyze the macro coordination ability, process and processing sequence, and manufacturing and processing ability respectively by est...
