The system is designed according to the mechanism of CAD Standard Part Graphies Files. SQL Server 2000 is selected as the host and construct the database of part liabrary due to characteristic parameter. STEP, viz. ISO 10303, is issued by international standardization organization, and here ,this paper gives the definition of product information model oriented part41 and part44 in STEP and six basic definienses which describe the product information to ensure the information in the product information model correct and shareable . This paper also presents method of creating and extracting product information on engineering draught and product data exchange and integration between CAD system and database manager system.

论文中采用&CAD标准件图形文件机制&，用SQL Server2000数据库建立了零件的特征参数数据库，完成了零件库的特性参数库建库工作；依据国际标准化组织的STEP标准即ISO 10303中的Part41，Part44两部分内容以及STEP标准中描述产品信息的六个基本的类库定义，提出了一种产品信息模型，保证了产品信息模型中信息的正确性和共享性，实现了工程图样中产品管理信息的建立和提取以及数据库系统与图形文件中的管理信息交换与集成。

The sensitivity analysis results show that ticket price changes have a significant effect on flight load. Analysis of the influence of different flight departure time alteration on flight load may also serve as a reference for the flight departure time adjustment considerations of airlines. Furthermore, the estimation parameter value in passenger choice utility function for passengers to early arrival is less then to late arrivals. This shows that domestic flight passengers prefer the early arrival flight to late arrival flight under the same time difference between passenger desired departure time and flight departure time.

另由敏感度分析之结果，显示票价变动对班次承载之影响明显，而变动班次起飞时间对班次承载影响之分析，亦可作为航空公司调整其班次起飞时间之参考；此外，由旅客选择效用函数中班次时间差之参数，早到与晚到校估值的差异，以及采早到与晚到对旅客吸引时间范围不同时，其估计误差较采早到与晚到时间范围相同下小，此等结果皆显示国内旅客对於早到与晚到的感受不同。
