Quality Function Deployment (QFD) is a quality management tool that transmits customer requirements into product design or innovation process to improve products' customer satisfaction. For the first time, this paper points out the distortions of customer requirements existing in the transmission process of QFD that are caused by the methods for calculating the importance degree of output information. The distortions lead to the designed or innovated product meeting less important customer requirements, without meeting more important customer requirements, so products' customer satisfactions are decreased. In order to avoid the distortions, a new method for calculating the importance degree of output information is proposed and an example is illustrated to demonstrate the effectiveness and superiority of the new method.

Online hotel reservation makes travel easier, But a large number of online hotel information also makes people become unable to follow. Online hotel reservation websites need try to gain exposure to customers' eyes and recommend a personalized hotel list. Nowadays, Personalized Intelligent Hotel Recommendation Systems have been researched widely, but rarely in online hotel reservation. The paper summarizes representative online hotel reservation websites' personalized recommendation system situation, such as qunar, kuxun, ctrip and elong etc. personalized recommendation have poor performance. This research firstly extracts Hotel Characteristic factor , attempts to analyze customers' browsing and purchasing behaviors and secondly constructs a personalized online hotel marketing recommendation system polymerization model for Multi-level customer ,at last presents an achieve Matlab procedure implementing the core arithmetic of the personalized recommendation.

In the process of product innovations, it is necessary to evaluate the sustainability of innovative products in order to meet the demands of sustainable development. So, the calculation process for evaluating the sustainability of innovative products is proposed in this paper. Firstly, the performances of the innovative products in social, economic, and environmental aspects are calculated based on the concepts proposed in this paper, including social matching degree, economic feasible degree, and environmental improving rate. Then, the vector-cosine method in the three-dimensional space is proposed to calculate the sustainability integrated in the three aspects, which regards innovative products as the vectors. Both the size and direction of the vectors are considered to calculate the sustainability. Finally, a case study of the cloud rail made by BYD Company in China is provided to illustrate the validity of the proposed calculation process.

Product innovation is an important means to compete for markets for enterprises during the era of mass customization. Manufacturing enterprises pay more attention to the innovation ability in product design and development field. The objective of this research is to solve rapid innovation design questions of the large-scale valve through establishing rapid design process model based on product platform. At the same time, the model is used in the actual product innovation design process. Combining with actual circumstances of a large-scale valve enterprise in China, rapid design process model based on the platform strategy is proposed. It includes three parts: platform establishing process, configuration resources database constructing process and platform applying process. Platform establishing process accomplishes constructing process of product platform. Configuration resources database constructing process is to program platform's product family according to platform configuration model of valve products and store correlative information of valve products. Platform applying process is a rapid design process according to the customers' customized demands. Moreover, key technologies based on the rapid design process model are analyzed. Prototype system and factual application example is addressed.
