1. Most transshipment network modeling problems assume the costs are constant. For example, the costs of shipping a product from one city to another are assumed fixed. This can change over time if fuel costs change. If you knew the distribution of fuel costs, how could the distribution of fuel costs be incorporated into the transshipment problem? Discuss the benefits of employing this approach.
2. Minimum spanning trees were initially design to solve electrical grid problems but now have many more applications such as computer networks, transportation networks, and supply networks. Describe a business problem where minimum spanning trees can be used to find a solution.
