defining the problem 最重要也是最难的对于OR

mathematical modeling is the cornerstone of OR 数学建模是Operations Research的基石。

intangible(unquantifiable) factors (such as human behavior) must be accounted for in the final decision.

1.1 Operations Research Models

To illustrate this point 为了阐述这一点

2（w+h）<=L

w>=0;h>=0;\Maximize z=wh;

the General OR model canbe organized in the following general format

Maximize or minimize : Objective Function

　　　　　　　　Subject to : Constraints.

Feasible: If it satisfied all the constraints.

Optimal if Being feasible,it yields the best value of the objective function.
