Recommendation system and method of mechanical product design document

Abstract

The invention discloses a recommendation system and a method of a mechanical product design document. An existing recommendation system and a method on the recommendation basis of the interest models of users can not adapt to the condition that the demands of users change rapidly. The system provided by the invention comprises a task monitoring module, an body interpretation module, a recommendation rule learning module, a recommendation module, a recommendation rule base, user activity logs, a decision table and an body base. The method provided by the invention comprises the following five steps of 1 creating an body model; 2 collecting the user activity logs; 3 generating recommendation rules; 4 capturing a newly assigned design task; and 5 recommending design documents. The system andthe method provided by the invention consider the features of a recommended object and employ the body to establish a relevant model, thereby adding semantic information for the recommended object, and improving the accuracy of the recommended rules. The system and the method provided by the invention also monitor the design activity ofthe users, thereby making document recommendation and the work flow of users combine closely, and can quickly adapt to the change of document demands of the users and ensure the quality of document recommendation.

Description

technical field [0001] The invention belongs to the technical field of computer applications, and in particular relates to a recommendation system and method for mechanical product design documents. Background technique [0002] Mechanical product design activities have transitioned from experience-based in the past to knowledge-based today, with the characteristics of highly knowledge-intensive, distributed, and collaborative work. To assist mechanical product design, some computer-aided software is used in design activities, mainly AutoCAD, IntelliCAD, Pro-Engineer, Windchill PDMlink. At the same time, in order to control the product design process, workflow engines such as jBPM and K2.Net series are also widely used. With the rapid changes in market demand, the design cycle of mechanical products is getting shorter and shorter, which has brought huge work pressure to designers. As an important carrier of knowledge, design documents have extremely high value. They have a...

Problems solved by technology

However, in the design activities of mechanical products, the needs of designers for documents change with the changes of the design tasks that designers are currently engaged in, and the user interest model has stability for a certain period of time, so it cannot be designed simply based on user interests document recommendation

The existing information recommendation technology is difficult to be directly applied to the recommendation of product design documents, so it is necessary to propose a recommendation method for mechanical product design documents
