The hta model was used to compose the story around the event of a phlebotomist drawing a patient ' s blood that supports the goal - based structure of the scenario Hta模型被用来围绕医师抽取一个病人血样的事件组合故事，来支撑典型场景的基于目标的结构。
2.
Here are some examples of the requirements specified for this case study : ( 1 ) avoid conflicts among phlebotomist ' s tasks caused by the room layout ( from the hta model and the spatial layout model ) , ( 2 ) reduce the number of devices and containers to save space ( from the spatial layout model ) , and ( 3 ) improve recording and transferring information accurately to other sections of the hospital ( from the information flow model ) 这是在这个案例中的一些特殊需求的例子： （ 1 ）避免在医师任务和房间内空间规划上发生冲突（从hta模型和空间规划模型得出） ， （ 2 ）减少设备和容器的数量以节约空间（从空间模型） ， （ 3 ）改进记录和精确的转化信息到别的地区的医院（从信息流模型得出） 。
