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。$ V& [- t/ n9 L3 Q4 V; p8 C
: B, C" `% j& p5 H" Kbegin P_wait arriving
' K, D- O3 _4 G+ l if this load type=L_a1 then( ]* g! V4 e7 G+ n3 r
wait to be ordered on OL_1
! M/ g/ i2 g$ B2 `+ o. U if this load type=L_b1 then- c& e5 z- O& @9 `
wait to be ordered on OL_2
