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。
: D. a/ A! m+ C/ c' C2 f% j3 P1 X2 `, c7 ?
begin P_wait arriving
9 \& z* X1 o+ F8 {# k if this load type=L_a1 then% [1 e2 ^. ^, Z7 {9 |0 V
wait to be ordered on OL_1: Y9 f! z/ z6 y( f x; O
if this load type=L_b1 then
/ A5 E* h: p3 @( s) O. k- z wait to be ordered on OL_2
9 _0 d, b/ M! h& e send to P_assemble4 [- j' U1 V- w# T6 V! x0 K: p
end
