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。: Q5 A% [9 B; |1 G/ {
/ A* K2 }& B; m' a3 n
begin P_wait arriving# c) N, H4 e3 r: U6 m
if this load type=L_a1 then
# d& N) t8 n, W% O7 q& Y wait to be ordered on OL_1
& G; S+ a: N& M& p+ o# \0 b if this load type=L_b1 then, f) P3 K% G, q0 c: r
wait to be ordered on OL_2
