What is transportation problem and assignment problem?
James Craig updates
The Transportation and Assignment problems deal with assigning sources and jobs to destinations and machines. We will discuss the transportation problem first. Suppose a company has m factories where it manufactures its product and n outlets from where the product is sold.
.
Herein, how assignment problem is a special case of transportation problem?
A special case of the transportation problem is the assignment problem which occurs when each supply is 1 and each demand is 1. In this case, the integrality implies that every supplier will be assigned one destination and every destination will have one supplier.
Secondly, what is the difference between assignment problem and Travelling salesman problem? Travelling salesman problem is also a method of assignment problem in which we have to make the decision about the assigning the task to the sales persons. Under travelling salesman problem , a person who is a salesman has to went to different cities only once but they have to return to there starting point.
Besides, what is the problem of transportation?
Below are some major problems of road transportation: Traffic Management. High rates of accidents on the roads due to poor state of the roads. There is a lack of accountability of some Regional Engineers in the country.
What is an assignment problem in operations research?
Assignment problem is a special type of linear programming problem which deals with the allocation of the various resources to the various activities on one to one basis. It does it in such a way that the cost or time involved in the process is minimum and profit or sale is maximum.
