摘要:
 为缩短产品研发周期和提高产品设计质量,需要实现设计资源的主动推送服务,而要实现设计资源的主动服务,需要解决设计资源服务的需求获取问题.设计资源服务需求具有复杂性与多变性,为解决如何快速高效地获取设计资源服务需求问题,在分析情境感知推理层特点的基础上,构建了主动获取设计资源服务需求的情境感知服务体系.采用贝叶斯方法使设计资源类别偏好情境化,并根据不同的情境特点,为选择合适的且能融合到推荐中的方法,提出了融合资源类别偏好的协同过滤获取算法.通过多个设计资源服务需求的期望值计算及其大小比较,实现了基于情境感知的设计资源服务需求的主动获取.验证实例结果表明,所构建的服务体系和所提出的算法可行、有效,为设计资源主动服务理念提供了新思路.
Abstract:
 In order to shorten the product development cycle and improve the quality of product design,it is necessary to realize the active push service of design resources needing to solve the requirement acquisition problem of designing resource service.To design resource service requirements are of complexity and variability.In order to solve the problem of how to access the requirement of design resource service more quickly and efficiently,based on the analysis of the characteristics of the context aware reasoning layer,the context aware service system is constructed which can access the requirement of design resource service actively.Bayesian approach is used to make the design resource type,and according to the characteristics of different situations,in order to select the appropriate method which can be integrated into the recommend,a collaborative filtering algorithm based on the preference of fusion resources has been proposed.By calculating the expected value of the service requirements of a number of design resources and comparing their size,the active acquisition of design resources service requirements based on the context aware is realized.The verified example results show that the constructed service system and the proposed algorithm are feasible and effective,which provides a new idea for designing resource active service.
