Problem attached
Consider a transshipment problem consisting of three origin nodes, two transshipment nodes, and four destination nodes. The supplies at the origin nodes and the demands at the destination nodes are as follow:

Kindly see the steps and solution below. It is also attached as word file. Hope this is useful to you.
Response:
a. Network representation: Following is the network representation. For the sake of simplicity and clarity while LP formulation I have denoted transshipment nodes as 4 and 5, and destination nodes as 6, 7, 8, and 9. Arrows show transportation routes

d. Formulate the appropriate linear programming problem
Let us look at decision variables first. Decision variable should convey quantity to be shipped along the specific routes.
x14 be the quantity shipped from source node 1 to transshipment node 4. Similarly we define x15, x24, x25, x34, x35.
Let x46 be the quantity shipped from transshipment node 4 to destination node 6. Similarly we define x47, x48, x49, x56, x57, x58, and x59

Solution Summary

Word file contains solution for Transportation, Assignment, and Transshipment problems.

Please help in solving a review problem for a final exam. I am having trouble setting up the problem in Excel. The goal of the problem is to find the minimum transportation cost associated with the network.
I have attached a diagram (see the attachment).
The following diagram shows a transshipment network. Nodes 1, 2, and 3

I need help trying to find the answer. I have tried about 20 different constraints and all of them are wrong. I don't know what I am doing wrong. Some of the constraints that I have tried are x4 + x6 = 175 and x6 + 0 = 175 just to give you an idea of the way that I am thinking. Evidently it is wrong. Please guide me in the

In setting up the an intermediate (transshipment) node constraint, assume that there are three sources, two intermediate nodes, and two destinations, and travel is possible between all sources and the intermediate nodesand between all intermediate nodesand all destinations for a given transshipment problem. in addition, assume

Please make sure all work is shown to include the tables so that I can do a comparison to make sure the way I think it should be done is being done. While QM for windows can be used to solve this, I would appreciate the other way shown as well so that I can understand what is going on verse having a program do the work for me.

In addition, assume that no t

TRUE/FALSE
1. In a transportation problem, items are allocated from sources to destinations at a maximum cost.
2. The linear programming model for a transportation problem has constraints for supply at each source and demand at each destination.
3. In a balanced transportation model where supply equals demand, all con

21. In a balanced transportation model where supply equals demand, none of the constraints are equalities.
22. In a transshipment problem, items may be transported from sources through transshipment points on to destinations.
23. An assignment problem is a special form of transportation problem where all suppl

Part 1 Transportation
The following network describes a transportation scenario in which there are four sources A, B, C, and D; and there are three destinations P, Q, and R. (The numbers next to each arrow represents the cost of transporting one unit from that particular source to the destination located at the other end of th
