Product demand analysis method and device

The embodiment of the invention discloses a product demand analysis method and device. The method comprises the following steps: according to a product demand, generating a demand dynamic simulation system for realizing the product demand by utilizing a first large language model; according to the product demand, testing the demand dynamic simulation system by using the second large language model so as to verify the product demand; the demand dynamic simulation system is operated in the human-computer interaction interface, so that the product demand is confirmed in a human-computer interaction mode; and according to verification and confirmation, obtaining an acceptable demand dynamic simulation system and a reasonable product demand. According to the embodiment, the analysis efficiency of product demand rationality can be improved, product demand iteration is accelerated, problems are found in the early stage of product research and development, and the product development cost is greatly reduced. 本发明实施例公开
