Intuitionistic Fuzzy Quality Function Deployment Based Telecommunication Product Planning

As an important part of high-tech industry, Chinese telecommunications equipment industry has developed into a more complete system and is advancing in high-speed. High-quality telecommunications products planning process is the crucial factor for successfully developing telecommunications products。Scientifically converting the customer requirements into proper technique features of products is significant guarantee for product planning. Quality Function Deployment is an efficient quality management method, and plays a vital role in the entire disciplinary system. It has been a powerful approach in successful implementation of customer satisfaction. Practical applications show that the quality function deployment can significantly shorten product development cycles, enhance internal communication, ameliorate product quality, improve customer satisfaction and ultimately enhance business performance.However, with the increasing complexity of economic systems, product development has to deal with plenty of information with fuzzy, imprecise and incomplete characteristics, which inevitably makes the input information of quality function deployment is inherent imprecision and uncertainty. These factors highlight the shortage of traditional quality function deployment using precise digital description form. The traditional quality function deployment needs to be improved since the expected significant effect is difficult to achieve.In this dissertation, the problems and shortages mentioned above have been studied for telecommunication product planning based on intuitionistic fuzzy set theory, multi-attribute group decision theory, quality function deployment method, and market theory. By studying telecommunication equipment market, first, the intuitionistic fuzzy quality function deployment model is proposed; secondly, multi-attribute group decision based on intuitionistic fuzzy set for product target market is established; thirdly, the method to determine importance of customer requirements from target market is put forward by using intuitionistic fuzzy set; finally, the importance of technique characteristics in product planning is confirmed by the presented method using intuitionistic fuzzy. This dissertation discusses the problems of current product planning and analyzes the importance of studying the telecommunication products planning. A systematic research of telecommunication equipment market, quality function deployment and intuitionistic fuzzy set theories and methods are also presented.An intuitionistic fuzzy product planning house of quality framework is proposed. Based on this framework, the multi-attribute group decision for target market is analyzed, together with the study of the customer requirements and techniques characteristics.From the perspective of marketing theory, the product market segmentation methods and the assessment and decision-making pattern of target market are analyzed. Based on the intuitionistic fuzzy multi-attribute group decision making method, the traits of telecommunication product market segmentation are studied, and the assessment model of target market for telecommunication product is put forward.With the selected target market, the customer requirements in target market are analyzed. The consistency of group decision-making is discussed in multi-attribute group decision making model based on preference matrix. The basic importance model of customer requirements with intuitionistic fuzzy preference matrix is built based on the developed Markov Chain Mote Carlo algorithm. By considering the market competition, the competition importance model is also established using intuitionistic fuzzy similarity calculations. The final importance model of customer requirements is determined based on the basic importance model and competition model. Each importance model is verified by application in telecommunication product planning.The importance of technique characteristics relies on that of the customer requirements from target market. The intuitionistic fuzzy entropy is analyzed to objectively distribute the weights of decision experts in multi-attribute group decision making, which contributes to the proposed basic importance model of technique characteristics. By discussing the competition in different enterprises, the competition importance model is established with cross entropy of intuitionistic fuzzy sets. The final importance model of technique characteristics is determined based on the basic importance model and competition model. Studying the importance of technique characteristics in telecommunication product planning, the built models are verified to be valid and feasible.In the end, the proposed method for telecommunication product planning is generalized and the innovation of research is summarized. The further research and direction to be made are given.
