设A， B， C产量分布为x1，x2，利润目标函数为 Z=3*x1+5*x2+2*x3 (Profit Maximize)约束条件: Subject to:x1<=800 (capacity of A)x2<=1200 (capacity of B)x3<=1000 (capacity of C)x1+x3<=1000 (capacity constraint)x2+x3<=1200 (capacity constraint)x1+x2+x3<=1200 (capacity constraint)x1<=600 (Constraint of A)x2>=200 (Least requirement of B)属于线性规划问题需要求解的话，请追问
