Transportation Models
Transportation Models. Transportation problem is about distribution of goods and services from several supply locations to several demand locations. The objective in the transportation problems is to minimize total distribution costs (to meet the demand with the minimum cost). Initial Solution.

Chapter 9 Transportation and Assignment Models The Transportation Problem To find the most economical way of allocating m sources to n destinations. – PowerPoint PPT presentation
- To find the most economical way of allocating m sources to n destinations.
- Capacity of each source
- Demand of each destination
- Transportation cost to ship one unit from a source to a destination.
- The methods in textbook 9.5, and 9.6 are for doing by hand.
- Do not worry about them.
- Management users use computer software QM for Windows. (p.393-394)
- We use this method!
- Where total supply ? total demand
- Solve the problem same way as for the balanced transportation problem
- Dummy source / dummy destination
- If a route is prohibited to use, just set the unit transportation cost of that route to a large number.
- To assign m persons to m jobs.
- The cost (or efficiency index) for a person to do a job.
- It can be solved conveniently by using the Assignment module in computer software QM for Windows.
- It is a special transportation problem.

Assignment Models The linear programs in Chapters 1 and 2 are all examples of classical ''activity'' mod-els. In such models the variables and constraints deal with distinctly different kinds of activities — tons of steel produced versus hours of mill time used, or packages of food bought versus percentages of nutrients supplied.
assignment problem tries to model these behaviour. Therefore, the traffic assignment will be discussed before adressing bi-level formulation of the network design problems. 2 Traffic assignment The process of allocating given set of trip interchanges to the specified transportation system is usually refered to as traffic assignment.
In addition, total supply equals total demand. The classic assignment model is characterized by a set of people, a set of tasks, and a score for each possible assignment of a person to a task. ...

Transportation Model • Product is transported from location to location minimum cost • Each source able to supply a fixed number of units • Each destination has a demand for a fixed number of units • Can have multiple solutions, but the same minimum cost.
quantities in the model will have integer values and implementation will require that the distribution quantities also be integers. Fortunately, the unit coe cients of the unknown variables in the constraints guarantee an optimal solution with only integer values. 4.3.3 Initial solution - Northwest Corner Rule

Patient Assignment Models in the ED 609. PATIENT ASSIGNMENT TO FAST-TRACK AND VERTICAL PATHWAYS Another model in which patient assignment plays a role is in the streaming of patients into different areas of the ED, staffed by separate providers, based on their initial pre-sentation. This most common version of this model is a "fast-track."
