Variants of transshipment problem

“…The Transshipment technique is used to find the shortest route from one point in a network to another. The problem of determining simultaneously the flows of primary products through processors to the market as final products has been formulated alternatively as a transshipment model by King and Logan [10] and as a reduced matrix model by Rhody [11]. An extension of this problem to a multiregional, multiproduct and multiplant problem formulated in the general linear programming model has been proposed by Judge et al [12].…”

A Negative-Cost Approach to the Formulation of a Transhipment Problem

“…The transhipment problem formulation has been and is still being used extensively by researchers to solve spatial equilibrium and plant location problems. Hurt and Tramel [2], King and Logan [4], Rhody [7], and Judge et.al. [3] have all treated the subject of alternative formulations of transhipment problems.…”

Groundwater mining in the Ogallala Aquifer in relation to rising energy prices and agricultural production

“…The area irrigated in the South Ogallala Zone, which basically corresponds to the Southern High Plains of Texas and New Mexico, is about the same in 1974 as it was in 1959, as shown in Figure 1 ^Data include all irrigation in the regions including groundwater from all sources, privately and public«ily provided surface water. Groundwater from the Ogallala Aquifer would irrigate around 80%, 98%, and 100% of the acres shown for the Nocth, Central, and South Ogallala zones, respectively, in 1969. ^Source: Department of Commerce (1961,1967,1972,1977).
