Problems solved by technology

Knowledge recommendation in the design knowledge process is mainly to match the corresponding design knowledge, that is, design documents, according to the design tasks in the design process. However, there are few studies on how to help design documents match th...

Embodiment Construction

[0060] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0061] The technical solution adopted in the present invention is: a workflow model recommendation method based on the design information ontology model, as shown in the attached figure 1 As shown, follow the steps below to implement:

[0062] Step 1. Divide the design information in the PDM system into basic attribute class (BasicAttr), operational attribute class (OperationAttr), semantic attribute class (SemanticAttr), morphological attribute class (FormatAttr) and relational attribute class (RelationAttr). Construct the design information model and map this model to the workflow model (see appendix figure 2 ).

[0063] The basic attribute class refers to the general attribute class of the data object, including three attributes: file attribute (FileAttr), source a...

Abstract

The invention discloses a workflow model recommendation method based on a design information model, wherein a design document, design information, a design process and a recommendation algorithm are constructed into three models, and the three models jointly form a workflow model recommendation algorithm method. The three models are respectively mathematical models of a design information model, aworkflow model and a recommendation algorithm. The design information model body comprises various types of design information of a design document, such as basic attributes, operation attributes andsemantic attributes, and the design information can be obtained by mapping a workflow model. Basic entities contained in the workflow model are processes, tasks, resources, entity roles and organizations in the resources, and business products in the workflow. A mathematical model of the pushing algorithm is composed of an entity node similarity calculation method, an optimal weight vector searchmethod and an ontology matching similarity integration method. The method has important value significance for improving the working efficiency of engineers, shortening the product development life cycle and promoting the informatization development of enterprises.

Description

technical field [0001] The invention relates to the recommendation field, in particular to a workflow model recommendation method based on a design information model. Background technique [0002] With the wide application of business process management technology in product design, the growth rate of business processes and product categories in PDM (Product Data Management) will far exceed the processing speed of designers, making enterprises face the challenges of business process management and product data management. difficulty. When design documents enter the business process, in order to improve the efficiency of design documents entering the workflow model and enable engineers to focus on product design and perfection of design information, it is necessary to recommend a suitable workflow model for design documents, so the workflow model recommended Accuracy and efficiency are particularly important. In May 2009, the Natural Science Foundation of the United States ...
