for transferring costs. For our considered problem, which has small

and medium sizes, proposed algorithm is efficient; however, this algo-

rithm should be tested for large-size problems.

In this chapter, we have successfully formulated the IPODS prob-

lem as a mixed-integer nonlinear programming model with different

vehicles, time windows, and routing method of distribution. A heu-

ristic algorithm, which is a combination of GA and SA, is proposed

to solve the research problem. We solved 20 real problems by exact

method with Lingo 11.0 and compared the results with the solutions

of proposed heuristic algorithm and real-world cases. Computational

results showed that our solution method is effective and efficient. It can ...
