The general economic meanings and mathematical structure of the dual of a primal mathematical programming model have been discussed for many years. However, within the mathematical programming realm, many interesting formulization variations have developed partly in response to variations in particulars of problems.
A number of authors have discussed the economic meaning and mathematical structure of the primal of a linear cost minimizing transportation model. Some authors discussed the economic meaning and mathematical structure of the dual as well as the primal of the transportation model. Several authors discussed cost minimizing transshipment models. Recently, greater interest has been shown in specific economic meanings of the dual of the cost minimizing transshipment model.
