=========================================
在bate2版的基础上:
产品名由原来的 akai_note 改为 ackeline_note
便笺的默认储存位置从原来的 D:Program Filesakai_note
改为:D:Program Filesackeline_note
增加了便笺可以更改颜色的功能,六种颜色随心选!
akai 2011 from PHY. of CCNU 2013-2-22
=========================================(In the version on the basis of bate1:
Increased when closing a bar notes, location and size of the function of memory in a memo.
Follow the form of the button will no longer overflow
Change the help text styles
With the help of information added to
The default storage location notes from the original D: _ NOTE_TEMP change order
Now the D: Program Files akai_note
Optimize the use of the process instructions and tips
Separate storage of temporary files and temporary files folder
Solve the exit edit state, some time can not wrap text display issues

job
有m台不同的机器,n个不同的工件。每个工件有多道工序,每道工序由指定的机器在固定的时间内完成。一道工序一旦开始处理,就不能中断。每台机器一次只能处理一道工序。一个调度就是决定每台机器上工序的处理顺序,使得机器完成所有工件的时间最短。具体的,该问题就是要求在满足(1)、(2)两个约束条件的前提下,确定每台机器上工序的顺序,使加工的时间跨度(从开始加工到全部工件都加工完所需要的时间)达到最小。其中,(1)表示工件约束条件:对每个工件而言,机器对它的加工路线是事先确定的;(2)表示机器约束条件:对每台机器而言,一次只能对一道工序进行加工。()
