Description
Technical field
The present invention relates to task corresponding technology field.More particularly, to a kind of design and processes based on structure matrix
The correlating method of task.
Background technology
In the development process of product, typically all early stage designer carries out product design, and the later stage, production division was according to setting
The design requirement of meter person carries out product generation.At present, in the development process of complex product, easily there is design process and production
The problem that process is mutually isolated, often causes the multiple of design and production division to do over again and coordinate, and greatly causes production
The growth in cycle, the reduction of production efficiency and the raising of production cost.
In the prior art, in order to reduce number of times of doing over again, improve productivity and quality, it is typically chosen appointment process engineer
Intervention is begun in design early stage, design is participated in jointly with designer.Designer enters design process according to different maturity
Row classification, as maturity is deepened, the information of structure design is more perfect, in structure design maturity in early days, process engineer
Designed structure can be examined with structure design Shi Yitong, and propose manufacturability issues, improve the structure designed by improvement.So
And, as design objective increases, and design department and technique department are generally the Liang Ge departments being separated from each other, in personnel's coordination, ditch
Often there is a problem of inefficiency on logical, the personnel of the simple dependence different role of design and craft knowledge concentrate and examine
Look into, it is difficult to effectively advance R＆D process.

As shown in figure 1, in the present invention, a kind of correlating method of the design and processes task based on structure matrix, the association
Method is comprised the following steps：
S1：The maturity for being designed process is divided；
S2：Technical process is carried out into Task-decomposing；
S3：Build the structure matrix of design and processes task；
S4：Determine task incidence matrix element.
Detailed process is as follows：
The first step divides design maturity and determines design content
Design process is divided into Pyatyi maturity, the first order is collectivity Scheme Design D1：Integral layout model is completed, it is internal
Structure space is laid out, and each essential component interface relation determines；The second level be overall structure frame design D2, complete main structure and its
Joint unit is designed, each part of product structure, the preliminary assembling scheme of equipment and docking site；The third level is checked for performance evaluation
D3, the loading analysis of complete design structure, structural strength analysis is calculated；The fourth stage is that structure final scheme designs D4, is completed most
Whole geometrical model, determines part, equipment connection scheme, and complete final strength verification and Dynamics Simulation Analysis；Level V
It is final design parameter determination D5, including each design parts mark, determine specifically used material model, three-dimensional general assembly scheme mould
Type, standard parts and components model determines.
Second step decomposition technique task simultaneously determines task definition
The process task that manufacturing process is related to is divided into：Raw material and standard component choose M1：Complete sheet material, tubing, bar
Technology Deng the selection and purchase of conventional material, and new material is tackled key problems, and standard component test machine is chosen；Process and road
Line determines M2：The technique sides such as the selection technological method for processing such as machine adding method such as car, milling, plane, mill, forging, casting, injection welding
Method, and formulate process route and cutting tool choice, parameter determination；Fixture designing M3：According to the process route and added formulated
The parts physical dimension of work, design frock, fixture；Assembling scheme determines M4：Design assemble sequence, targeting scheme etc.；Measurement
Conceptual design M5：Measurement scheme in design processing, assembling process, it is ensured that converted products meets design requirement；Quality testing scheme
M6：The quality testing of machine product after completing to assemble, if meet use requirement.
3rd step builds design, process task structure matrix
Structure matrix is m row m row two-dimensional matrixs Ai,j, the row of matrix represents p design process and q process task, matrix
Row represent with the one-to-one p design process of row of matrix and q process task, wherein, m, i, j, p, q for natural number and
M=p+q, 0 ＜ i, j≤m.
If i ≠ j, element a in structure matrixi,jIt is for representing that design process/process task that the i-th row is represented is arranged with jth
The numerical value of the degree of association of the design process/process task of representative；If i=j, element is sky in structure matrix.
For the product development process that process task has sequencing：
If i ＞ j, element a in structure matrixi,jRepresent that data, information or knowledge are transmitted from previous task to latter task；
If i ＜ j, element a in structure matrixi,jRepresent that data, information or knowledge are transmitted from latter task to previous task.
As shown in Fig. 2 the division of design process maturity, the technical process that are completed according to the first step in the present invention and second step
Task-decomposing, complete design, the structure matrix of process task association build.Structure matrix is 11 rows, the two-dimensional square of 11 row
Matrix representation, the top of structure matrix, Far Left and the design of placement order identical, process task on diagonal.
It should be noted that the present invention is illustrated and illustrated by taking p=5 design process and q=6 process task as an example
, but be not the restriction to embodiments of the present invention.
4th step task incidence matrix element determines
Except off-diagonal other elements represent incidence relation between design, process task in matrix, each task it
Between the strong and weak designer and technologist for needing specialty of coupled relation discussed determination according to real work situation.According to coupling
Represent that two tasks are mutually only if relationship strength can represent that numerical value is bigger, and coupling is stronger to preceding with numerical value 0-10,0
It is vertical, without coupled relation；10 represent that coupled relation is extremely strong.Such as, the determination of essential component interface relation will very in collectivity Scheme Design D1
Determine that assembling scheme determines M4 in big degree：The determination of assemble sequence, and determine asking for assembly feasibility during assemble sequence
The determination of feedback influence unit interface relation is inscribed, so the element at the row of 9 row 1 is 6 respectively, the element at the row of 1 row 9 is 4.
Can be obtained for the design during certain Complex Product Development, process task association knot according to actual design experience
Structure matrix is as shown in Figure 3.
Obviously, the above embodiment of the present invention is only intended to clearly illustrate example of the present invention, and is not right
The restriction of embodiments of the present invention, for those of ordinary skill in the field, may be used also on the basis of the above description
To make other changes in different forms, all of implementation method cannot be exhaustive here, it is every to belong to this hair
Obvious change that bright technical scheme is extended out changes row still in protection scope of the present invention.
