图 5.16 Function detail的设置

然后点击对话框下面Function Body中的按钮Actions按钮，在函数体中输入下面表达式语句：

Uvar.funpt = GAMMA (1 / Uvar.cv ** 2,mean * Uvar.cv ** 2,Uvar.mypns + ppns) RETURN Uvar.funpt !mean

点击OK完成输入，所有设置完成之后点击确定。至此，一个函数bt的细节化设置完成。依照此法，设置其余函，函数的设置程序如下：

对pm_part中的part元素进行设置。双击pm_part中的fengkouban, Arrivals中的Type设为passive(如图5.17),表明看板生产系统是拉式生产，双击Action on

14

Create,在弹出的对话框中填入fengkouban的属性(如图5.18)。

依照此法，细节化设置pm_part模块中的其他part元素。设置的程序如下：

ELEMENT NAME: pm_part.fengkouban Arrivals Type: Actions Create:

Passive Uatt.tpnum = 4

Uatt.qgnum = 8 Uatt.skqgtime = 25 Uatt.tptime = 18 Uatt.zktime = 25

_____________________________________________________________ ELEMENT NAME: pm_part.neigeban Arrivals Type: Actions Create:

Passive Uatt.tpnum = 4

Uatt.qgnum = 8 Uatt.skqgtime = 25 Uatt.tptime = 15 Uatt.zktime = 25

_____________________________________________________________ ELEMENT NAME: pm_part.neilunban Arrivals Type:

Passive

Actions Create: Uatt.jbqgnum = 3

Uatt.jbqgtime = 60 Uatt.dpktime = 40 Uatt.jytime = 25 Uatt.hjltime = 50
