The Transportation and Transshipment Problems,r with the minimum-cost diet problem of Stigler, the transportation problem was among the first formulations of linear programming problems. The Russian L. V. Kantorovich formulated the first specification of the problem in 1939, but his work became known in the West about a decade later. In 1941, F

Spaces, Cones, Bases and Extreme Points,ications. In this chapter we will examine more closely the geometric and algebraic structure of a linear programming model. For ease of exposition and graphing, we will discuss a very simplified linear programming problem with only two outputs and two inputs because we want to graph it in two-dimens
