(1) Product management subsystem
A. The product management subsystem can synchronize with the supply-chain management
subsystem between 4:00 am and 5:00 am every day for the information of electronic devices or
components of the electronic devices imported from other companies, including name, price,
amount, category and date. Therefore, the product management subsystem has two states:
synchronization state and normal state.
B. The product management subsystem can analyze all the devices’ and components’ order
history one by one every month, in order to show the hot devices and components, and to
generate a report suggesting promotion on some of the devices or the components.
C. The product manager can browse the list of the devices or the components, and sort them by
different key attributes: price, amount, date or discount. It needs to use quick sort algorithm for
price, amount and data, but use bubble sort for discount, due to the difference between these
attributes.
D. The product manager can set discount based on his own analysis and the report, and the
product management subsystem records this activity for future trace.
E. The product management subsystem can receive an order of the devices, check if there are
sufficient devices or components in storage, and approve the order. There are two kinds of
ordered devices: (i) electronic devices with fixed configuration or (ii) customized and assembled
electronic devices from components.
F. The product management subsystem can be accessed with either Internet browser or
command line interface.
（1）产品管理子系统
a.产品管理子系统能与供应链管理同步
每天4:00至5:00之间的子系统，以获取电子设备信息或
从其他公司进口的电子设备的部件，包括名称、价格、
金额、类别和日期。因此，产品管理子系统有两种状态：
同步状态和正常状态。
b.产品管理子系统可以分析所有设备和组件的订单。
每月一个接一个的历史记录，以便显示热设备和组件，以及
在某些设备或组件上生成建议升级的报告。
c.产品经理可以浏览设备或组件的列表，并按
不同的关键属性：价格、金额、日期或折扣。它需要使用快速排序算法
价格、金额和数据，但由于两者之间的差异，使用气泡排序进行折扣
属性。
D.产品经理可以根据自己的分析和报告设置折扣，以及
产品管理子系统记录此活动以供将来跟踪。
e.产品管理子系统可以接收设备的订单，检查是否有
储存足够的设备或组件，并批准订单。有两种
订购设备：（i）具有固定配置的电子设备或（ii）定制和组装的设备
电子元件。
f.产品管理子系统可以通过Internet浏览器或
命令行界面。
