The Transportation and Assignment Problems. Introduction. Transportation problem. Many applications involve deciding how to optimally transport goods (or schedule production). Assignment problem. Deals with assigning people to tasks. Control Problems in Experimental Research. Chapter 6. Control Problems in Experimental Research. Chapter Objectives. Distinguish between-subjects designs from within-subjects designs. Understand how random assignment can solve the equivalent groups problem in between-subjects designs. Polynomial Problems (P Family). The set of problems that can be . solved. . in polynomial time . These problems form the P family . All problems we covered so far are in P. P. Nondeterministic Polynomial (NP Family). Transportation, assignment and transshipment problems. Network flow model. Consists of nodes representing a set of . origins. and a set of . destinations. . . An . arc. is used to represent the route from each origins to each destinations.. Optimization. (Linear Programming). . CVEN 5393. Mar 14, 2011. Acknowledgements . Dr. . Yicheng.

Constraint Propagation. Place a queen in a square. Remove the attacked squares from future consideration. 2. Constraint Propagation. Count the number of non-attacked squares in every row and column . Ron . Lembke. Transportation Problems. Linear programming is good at solving problems with zillions of options, and finding the optimal solution.. Could it work for transportation problems?. Costs are linear, and shipment quantities are linear, so maybe so.. University. Modifications by. A. Asef-Vaziri. Chapter . 6, . Part A. Distribution and Network Models. Transportation Problem.
