linear programing

a real problem, a proposed solution within the boundaries of the class topics, use of these tools, and the realized results of the implementation.

Each group will present a summary of the selected paper：

1 First, introduce the background and industry.

2 Second, what problems has the solved with linear linear engineering projects, and what is the nature of this problem? What does it mean? If the problem is not solved, what will be the bad effect?

3 Third, what is the linear engineering model in this article？ why you find it interesting, and what you have learned？
