Answer: there are problems which are difficult or very difficult, and even on the fastest computers, they still take a lot of time or space to solve. Moreover, some problems can be solved efficiently, but bad designs will take too much time or space. Therefore, we must study methods that lead to good solutions. b) Suppose there are maximum capacities for plants and size limits (both upper and lower bounds) for warehouses. What is the relevant model now? c) Assume that each customer has to be served from a single warehouse; i.e., no splitting of orders is allowed. How should the warehousing model be modified? [ Hint.
