基于理想点-矢量投影法的创新需求权重确定方法

现有的创新需求权重计算方法大多只考虑顾客、技术人员和决策者三者中的一方或者两方对创新需求权重的影响,鲜有方法将三方同时纳入需求权重计算过程,这很容易造成因信息考虑不全面,造成需求权重的精确度不高或失准等问题。鉴于此,本文提出一种基于理想点-矢量投影法的创新需求权重确定方法,它将顾客、技术人员和决策者三方的诉求在三维矢量空间中进行集成。分别计算创新需求的需求类别因子、需求技术成熟度和需求偏好度,采用理想点-矢量投影法得到理想需求矢量,并在此基础上计算每项创新需求权重值。文章最后通过汽车方向盘的研发的案例,验证了所提方法的有效性和可行性。

Weight Calculation of Innovative Demands Based on Ideal Point-Vector Projection method

Most existing methods for calculating the weights of innovative demands only take one or two angles of the influence from customers,technicians and decision makers into consideration,and there are few methods to consider all the three parties into the process of weights calculation of demands at the same time,which lead to low accuracy and incorrectness of the weights calculation because of the incomplete information.In order to solve this problem,this paper proposes a method based on the Ideal Point-Vector Projection method to calculate the weights of innovative demands,this method integrates the influence of customers,technicians and decision-makers in three dimensions vector space.Calculating the demand category factors,demand technology maturity degree and demand preference degree,and using the Ideal Point-Vector Projection method to acquire the ideal demand vector,we calculate the weights of each innovative demand based on the ideal demand vector.An empirical study of the research and development of car steering wheel is illustrated and proves the effectiveness and feasibility of the proposed method.
