Problems solved by technology

However, these qualitative evaluation methods are easily affected by experts' personal preferences and knowledge limitations in the evaluation process. In order to make the evaluation of product concepts more objective and accurate, some quantitative evaluation methods need to be introduced.
[0004] At present, there is no quantitative method for judging the feasibility of product concepts

Embodiment Construction

[0034] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0035] Principle of the present invention is:

[0036] Existing product design data contains certain design principles and design rules, and existing products must be feasible. Therefore, using data mining and statistical learning methods, an evaluation model can be constructed from existing products to support the evaluation of product concepts, which will help to gradually get rid of the qualitative expert evaluation method based on personal experience. The function of the product represents the needs of customers, is the starting point of product design and development, and is also the basic criterion for testing product design results. Components that realize functions are an important aspect to reflect product performance and meet customer needs, and are directly related to all aspects of the design process. Through data mining, the relationship bet...

Abstract

The invention discloses a method for judging the feasibility of a product concept based on a knowledge base. The product concept knowledge base determines the key characteristic parameters of each product concept; randomly generates a set number of random product concepts, and all product concepts and random product concepts in the product concept knowledge base are used as training samples for the Bayesian classifier. The key characteristic parameters of the Bayesian classifier are used as the input of the Bayesian classifier, and the pre-set feasibility judgment results of the training samples are used as the output to train the Bayesian classifier to obtain the feasibility judgment model of the product concept; adopt the product concept The feasibility judgment model of is to judge the feasibility of the product concept to be judged. If the product concept to be judged is judged to be feasible, calculate the feasibility value of the product concept to be judged.

Description

technical field [0001] The invention relates to the technical field of product concept design, in particular to a method for judging the feasibility of a product concept based on a knowledge base. Background technique [0002] In the fierce market competition environment, new product research and development capabilities are an important source for enterprises to maintain competitiveness. In the process of product development, conceptual design is the most important, critical and most innovative link. Its main task is to complete the generation and evaluation of product concept proposals. The evaluation of conceptual proposals is the process of scoring the generated series of conceptual proposals under different evaluation indicators, and then selecting the most conceptual proposals. Since conceptual design is in the early stages of product development, the quality of the conceptual scheme will have a great impact on the subsequent stages of product development. Studies h...
