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。
- [" Q, O. J7 S7 ]( s O0 B* C% q3 j8 _* u0 y& g
begin P_wait arriving
% V. s' y5 A6 x$ Q Q# k% ]- { X* d, K if this load type=L_a1 then/ C4 y o* V7 x L6 A3 N) o
wait to be ordered on OL_1
$ u+ W2 d; n |0 ~( @9 _ if this load type=L_b1 then" u E8 T% ~- E1 K
wait to be ordered on OL_2

end
