Embodiment 1

[0075] This example proposes a screening method for typical problems in complex equipment delivery based on gray target decision-making, such as figure 1 , figure 2 shown, including the following steps:

[0076] Step 1: Build an evaluation index system for problems in the delivery process, and determine the weight of each index in the evaluation index system;

[0077] Step 2: Based on gray target decision-making, measure and calculate the model index of each problem in the delivery of complex equipment, so as to extract typical problems;

[0078] Step 3: Based on the heat map, visually display the model index of each problem in the delivery.

[0079] Further, the step 1 specifically includes the following steps:

[0080] Step 1.1: Build an evaluation index system for problems in the delivery process, specifically:

[0081] First, divide three first-level indicators, namely safety, repeatability and processing cycle;

[0082] Then, divide the security of the first-level i...

Embodiment 2

[0137] This embodiment provides a practical example on the basis of the above-mentioned embodiment 1:

[0138] Step 1: Determine the weight of evaluation indicators for typical delivery problems based on the AHP

[0139] Step 1.1 Determine the typical problem evaluation index system

[0140] The evaluation index system of the delivery problem consists of three first-level indicators, namely: safety, repeatability, and processing cycle; among them, "safety" includes three second-level indicators, namely: functional safety, performance safety, For structural safety, the "processing cycle" includes three secondary indicators, namely: technical difficulty, maintenance equipment, and staffing, and the "repeatability" includes three secondary indicators, namely: detectability, detection experience, and detection instruments ;

[0141] 1) Safety: refers to the impact of delivery problems on the safety of complex equipment, where functional safety refers to the lack or loss of funct...

Abstract

According to the method for screening the typical problems in the complex equipment delivery based on the grey target decision, the typical problems in the delivery problems are screened by setting the selection model, the processing efficiency of the repeated delivery problem is improved, and therefore the delivery period is shortened. According to the method, the evaluation index system for selecting the typical delivery problem is constructed based on the analytic hierarchy process, subjective and objective combination is achieved, reasonable indexes for evaluating the delivery problem are selected, and the accuracy of the evaluation result is improved. Meanwhile, typical delivery problems with relatively large influence degrees under three index systems of'safety ', 'repetition' and'processing cycle 'can be selected based on grey target decision, and reference is provided for the disposal of subsequent repeated delivery problems, so that the disposal efficiency of the repeated problems is improved.

Description

technical field [0001] The invention belongs to the technical field of complex equipment manufacturing and delivery, and in particular relates to a screening method for typical problems in complex equipment delivery based on gray target decision-making. Background technique [0002] In the field of intelligent machinery manufacturing technology such as aerospace, there are many complex equipment due to the complexity and high difficulty of the mechanical structure. Complex equipment is a high-precision, high-tech product, and the complexity of its structure determines the diversity of its problems. In the actual delivery process, there will always be various problems, which will lead to the delay of delivery work and the reduction of delivery efficiency. [0003] In the process of delivery, as delivery problems arise, new delivery problems will overlap to a certain extent with the original delivery problems that have been dealt with. At this time, due to the multivariate, ...
