Graphical solutions of transportation problems
Teaching steps
1. Guide students through discussion to find solutions of
transportation problems graphically. Remind them that graphs
of transportation problems are drawn similar to the way of
solving linear programming problems.
2. Assist students through discussion to identify the feasible
region and the corner points after the graph is drawn. Lead
them to use the corner points to obtain the optimal solution of
the given transportation problem.
3. Use Examples 7.3 and 7.4 in the Student’s Book to guide
students to formulate transportation problems. Encourage
students to explore additional resources, such as online
tutorials, or reference books, to deepen their understanding
and further practice.
4. Require students to attempt Exercise 7.2 in the Student’s Book.
Advise them to submit their work. Check the correctness of
their answers, and provide them constructive feedback.
