软件组件供应商的模糊任务指派模型

Fuzzy Task Assignment Model for Software Component Suppliers

以组件供应商参与软件产品的早期设计开发工作为背景,针对组件供应商中分配设计开发任务的问题,考虑组件供应商的设计能力、成本和开发时间的非精确性,提出了软件组件设计开发任务指派的模糊多目标规划模型.根据模型的特点运用α截集和扩展原理将模糊模型清晰化并求解.该方法利用质量功能展开(quality function deployment,QFD)工具确定软件产品中的组件权重,提出了改进的组件供应商参与下软件开发过程中的组件规划质量屋的结构模型.最后,以具体实例说明模型和方法的应用.

How a software component supplier assigns the tasks of design and development is studied if he has participated in the design and development. Taking account of his inexactness in design ability, cost estimation and time required for R＆D, a fuzzy multi-objective programming model is developed for the assignment of design/developing tasks of products. In the model, the a-cut and principle of extension are introduced to make the fuzzy model clear and solvable. With the QFD （quality function deployment） used to determine the weights of components in software products, an improved architectural model of HOQ （house of quality） for component planning during software R＆D is proposed under conditions that the supplier has participated in design/ developing tasks. A numerical example is given to illustrate the way to use the model and its applications.
