In the present embodiment, embedded type 3D product holographic information interactive module based on STEP: by this interactive module, the client can long-rangely complete the browsing of product three-dimensional model, rotation, convergent-divergent, plays up, perspective, graph transformation, dissect, how much with topology information extraction and the operations such as inquiry, measuring distance and angle and Change In Design suggestion mark, the understanding of intensification to product appearance, performance.Simultaneously, can help the client to participate in product design directly, obtain maximum satisfaction, thereby realize the doulbe-sides' victory of client and enterprise.
Based on this mutual device module of STEP normal data core exploitation, have the advantages that the development amount is little, be easy to realize.Based on STEP application protocol and STEP data file, both can transmit product data itself, can transmit data structure again, can transmit whole geological informations and the topology information of body.Based on the Heterogeneous Digital system integration of EXPRESS language and STEP application protocol mechanism and method as shown in Figure 2.
Utilize the topmost body representation B-Rep B reps of STEP AP203 and AP214, set up the B-Rep model that comprises three-dimensional body geological information and topology information of protocol compliant; According to the definite Schema(pattern of STEP agreement) regulation, only need standard label ID and the data value teletransmission user of data entity are got final product, and do not need a large amount of data of model of each transmission own; Holographic information by the STEP file teletransmission product of small data quantity very is to the user.The three-dimensional model that transmits by the STEP file is the model of " this structure ", does not need to change the original structure of body, can not abandon its how much and topology information, for the extraction that realizes information provides the foundation.Simultaneously, the Change In Design suggestion can be directly on three-dimensional model diagram three-dimensional mark.The reviser can add with word the form of 3 D stereo callout box, produces to revise mark, and the take over party can original three dimensional form restore the modification mark.Because this mark is 3 D stereo, no matter how model rotates, and its arrow will point to the target that is modified forever, can clearly express and transmit Change In Design information.
But the device of independent development information interaction on the basis of the above.Utilize the Java ActiveX Techniques, but exploitation have browse, the interactive software in the embedded web page of the operating function such as mark.By the STEP file of small data quantity, but user's quick obtaining product model information realizes the operations such as long-range 3D browses, plays up, has an X-rayed, dissects, and can mark the suggestion for revision function such as carry out that the information anti-pass is passed.
At present, hardware enterprise adopts mostly determines BOM, and product is made of some parts, and parts wherein have again BOM separately, form a hierarchical structure BOM.In the BOM that determines, the parts on each node are determined, represent with unique table identifier.The corresponding BOM of each product.When product variety increases, will cause the BOM structural redundancy.
GBOM is a kind of general BOM, and the mode of the data description large-tonnage product kind that its is can be enough limited has been avoided structural redundancy, has kept simultaneously the structural information of BOM.GBOM is made of a BOM structure and a selection tree.Wherein, the BOM structure is a hierarchical structure that is comprised of type component, and it has represented the universal product structure in the product line.Selecting tree is a hierarchical structure that is made of variable, variate-value and configuration rule, and it has represented the process of product configuration.Select to determine a concrete product BOM along the different branches of selecting tree.In GBOM, come universal product structure in management product series with the BOM structure.That is to say, a product line only need to be stored a product structure.GBOM utilizes and selects tree to manage specific product, selects tree by expansion, and successively definite variate-value is determined product BOM.The difference of different product embodies by the difference of part on leaf node, and part is independent of concrete product.Specific product BOM did not need storage before being determined.Therefore, only need the parts of the storage bottom, rather than store the BOM of specific product, thereby reduced to greatest extent the redundancy of product structure.
Fig. 3 represents the relation of the single product BOM of family structure and the BOM of product family structure, and product family's BOM structure is the abstract of the single product BOM of family structure, and the single product BOM of product family is the concrete composition of the BOM of product family structure.P in figure 1, P 2, P 3, P 4Four products with similar product structure and function and identical external interface.At first finding out can be as the minimum property set of the uniquely identified of example in type component except dash number or component name.The set that the attribute of type component forms is exactly the variables set of type component.Generally speaking, all type components have variables set associated therewith.The example of the combination that is allowed to arbitrarily of the value of variable in can unique definite type component set in variables set.For example, two variable par1 of the variables set of class part D and par2 respectively value be val11 and val21, example D1 that just can unique definite class part D.
After the variate-value in the type component set was all decided, all parts and part example had also been determined with regard to unique.But the combination that is not example in any type component is all reasonably, as not satisfying restriction relation, can produce conflict.For example, class part D selects example D1, D2, and corresponding class part E can only select example E1; Class part D selects example D3, D4, and corresponding class part E can only select example E2; This is the logical constraint relation.At this moment type component D and E can be set identical variable par1, and it is put forward, as the variable of their bottom parent part B.This variable is called as the external variable of this subclass parts D and E, the built-in variable of this parent part B.The external variable value of subclass part need to be inherited from the built-in variable of his father's base part.
Obtain on the basis of client's diversification information at the mutual device of STEP 3D and form ordering system, carry out the diversification order analyzing.The existing parts of diversification sequence information and enterprise are compared, and in conjunction with existing business strategy, Analysis deterrmination goes out the feasibility of sequence information and subsequent product configuration design.Its core is to find the solution even identical optimum example similar to tailor-made product.
Optimum example solver module of the present invention will utilize a kind of second-degree parabola fuzzy set case-based reasoning algorithm to realize finding the solution of preferred example.
For solve current C BR system indifferent to fuzzy attribute, can not effectively hint obliquely at field question essence and the deficiency such as solution efficiency is low, in conjunction with Fuzzy Set Theory in the naturality aspect the simulating reality world or event, by the Criterion model set, construct the para-curve subordinate function of its attribute, the computation attribute similarity, retrieve the optimum matching example, realize the rapid configuration design.For the similarity measurement problem in case-based reasoning, a kind of broad sense subordinate function similarity measurement algorithm is proposed; Consider that the characteristics of fuzzy interval attribute in case library and fuzzy set center on the impact of case similarity, have proposed the centre distance correction algorithm based on relative area; Employing is based on the Objective Weighting of similarity deviation information, and integrated subjective weight and objective weight become hybrid weight, has set up the overall similarity solving model of example.Designed and formed the fuzzy set Case-Based Reasoning that is applicable to product configuration design.
Whole case-based reasoning is found the solution flow process as shown in Figure 4.
Online self study example and parts library and administration module thereof based on cloud computing: set up parts library and product library.In order to drop into and to satisfy to greatest extent client's demand with minimum enterprise, simultaneously, improve the efficient of enterprise, the parts of enterprise are set up the library management system, reaching the optimum use of existing resource, thereby improve the efficient of product configuration.On the basis of parts, set up the case library management system, the existing product of enterprise is built storehouse and management, can be faster carry out variant configuration and design on the basis of customer demand obtaining more easily.
At present, in the product design of most manufacturing enterprises, Element Design occupies sizable proportion.And in Element Design, most part is the same or analogous standard part of structure.Therefore, in order fully to effectively utilize oneself Element Design resource of having of enterprise, improve the design efficiency of enterprise, shorten product development cycle, need to manage by system parts library.The use of parts library can improve parts search efficiency and reusability significantly, promotes the standardization of parts.The present invention intends carrying out part management by system shown in Figure 5.
Example upgrades the learning tasks of the system that realized.The study of case library of the present invention can on-line automaticly be completed, evaluation and correction by example trigger, namely determining whether to carry out example by evaluation and correction upgrades, example with higher rating is stored as examples of many successful, have the low example of estimating and be stored as unsuccessfully example, the renewal of example depends on the similarity of example in current example and storehouse.This part work comprise the form of the information of determining needs renewal, renewal, how index, how to store etc.
