example 1

[0060] Example 1: Analysis as an example with a transmission system design. Using the product planning quality house and parts planning quality house for routine quality function, customer demand is the domain u = {Reaction time short (U 1 ), Compact structure (U 2 ), High reliability (U 3 ), Easy to repair (U 4 ), Short development cycle (U 5 . Engineering technical parameters T = {circuit function (T 1 ), Cabinet structure (T 2 ), Circuit board structure (T 3 ), Heat dissipation (T 4 ), Reliability indicator (T 5 ), Maintenance indicators (T 6 . Parts Design Characteristic Database V = {Circuit Structure and Parameters (V 1 ), Box shape (V 2 ), Circuit board size (V 3 ), Assembly interference analysis (V 4 Apply preferred device (V 5 ), Thermal analysis (V 6 ), Reliability (V 7 ), Repairability (V 8 ), MTTR (V 9 .

[0066] Step 3: Solving key design activities through routine quality housing and improving quality house

[0067] Relationship matrix by routine quality housing and process planning quality houses to solve key activities. Defining the importance of various customer needs in the routine quality function of customer demand to engineering technical parameters, define the importance of various customer needs (K 1 K 2 K 3 ... K m ), The value range is [0, 10]. After the routine quality function is expanded, the relationship matrix of customer demand and engineering technical parameters is A ij (i = 1, 2, ... m, j = 1, 2, ... n), where A ij Level rating is performed by {0, 1, 3, 5, 7, 9}, in turn, indicating that it is not relevant, weakly related, weak correlation, general correlation, strong co...

Abstract

The invention belongs to the technical field of maintenance support engineering, and discloses a four-property comprehensive protection integrated design process decomposition method based on an improved quality house. Obtaining a relation matrix of part design characteristics, customer demands and engineering technical parameters and a relation matrix of the engineering technical parameters and the part design characteristics; step 2, by improving quality function expansion, mapping the part design characteristics into design activities, and obtaining a relation matrix between the part design characteristics and the design activities and a correlation matrix between the design activities; 3, solving a key design activity; 4, converting a correlation matrix between design activities into a design structure matrix; 5, coupling activity in the design structure matrix is recognized; the coupling activities are segmented and sorted; and step 6, sorting the coupling activity as a single activity and a non-coupling activity.

Description

Technical field [0001] The present invention belongs to the technical field of maintenance and supporting engineering, and in particular, the present invention relates to a method of decomposing a four-sexual integrated design process based on improved quality housing. Background technique [0002] The essence of product design is to meet the needs of customer needs. Reliability, Maintenance, Testability, Safety, Safeability and Comprehensive Guarantees (hereinafter referred to as "Four - sex Integral", see if GJB 451A "Reliability Maintenance") is whether it affects the performance indicators of complex product The overall role of the overall role. In order to achieve a high level of effective design, we must meet the four - sexual maintenance needs of the product on the basis of ensuring product functionality. Four-sex fundamental integration needs mainly include four categories: four - sexual integrated integration indicators and requirements, undesirable events, conditional r...
