现有二类产品，A和B，如何实现1个A和1个B组装成1个C？我用orderlist建了二个OL_1和OL_2,分别用于A和B的等待，到了下一个进程，要取用的时候，一个都取不出来，实在不知为什么了，请大侠帮忙。* H s8 i4 ^7 n8 ~7 `
$ n1 ^1 T# u5 J0 A
begin P_wait arriving6 `, j: r. {: [& A# n: Q
if this load type=L_a1 then( r% ?7 T* V5 P) \. S5 k
wait to be ordered on OL_1
! ?7 h3 G, X3 _8 j0 O if this load type=L_b1 then
( Y( j9 k" K* o. ]' ` wait to be ordered on OL_2
