| 摘 要： | 针对液压缸价格估算的影响因素多、难以建立直接的数学模型问题，采用德尔菲法，通过总结本领域内多位专家的经验知识，找出了内径、行程、压力等级、是否伺服缸、安装形式、厂家资质和生产者物价指数（producer price index，PPI）等7个影响液压缸价格的关键因素，建立了基于BP神经网络的液压缸市场价格估算模型，并用实例验证了该模型的有效性。模型中所引入的PPI可以提高该模型对市场环境变化的敏感度，使基于该模型的市场价格估算准确度更高。 |

| Abstract： | There are many influencing factors of hydraulic cylinder market price and it is hard to establish a direct mathematical model. The objective of this paper is to develop a forecast model of market price for the hydraulic cylinder via the application of BP neural network. Seven critical factors related to market price of hydraulic cylinder have been found out by the means of Delphi, which are cylinder bore diameter, stroke, pressure rating, servo cylinder or not, installation type, manufacturer qualification and producer price index (PPI). Case study is used to prove that neural network is capable of forecasting market price of hydraulic cylinder. The PPI introduced in the model can improve the model sensitivity of market change to make the forecast more accurately. |
