In the book "Linear Programming and Economic Management" written by Qian Zhijian and others, linear programming was described as an emerging discipline that began to develop in the late 1940s, and it received the linear economic model of the 1930s. The discussion and the direct input of Leon Jeff's input-output model promoted, learned and summarized the actual experience of the US Air Force's logistics during World War II. According to the content of this book, he believes that the best allocation of research limited resources is linear programming, in order to achieve the given purpose and obtain the best economic effect. In the book "Linear Programming" written by Sun Xiu'e and Song Zengmin, linear programming is discussed as one of the important branches of operational research planning theory, and is a decision-making technology to study and solve optimal problems. It studies and solves from a holistic perspective how to maximize the use of human, financial and material resources; researches and solves how to find the best solution among all feasible solutions, and then obtain the best economic benefits. Linear programming is a mathematical algorithm to obtain the optimal value of the objective function under the premise of satisfying certain constraints.
