Consider modeling a warehouse with three in-flow arcs and three outflow arcs. The warehouse node is a transshipment node but has a capacity of 100. How would one modify the network model to avoid adding a side constraint that limits either the sum of in-flows or the sum of the out-flows to 100?
A) Place a limit of 34 on each in-flow arc.
B) Add a side constraint limiting the out-flow arcs sum to 100.
C) Separate the warehouse node into two nodes, connected by a single arc, with capacity of 100.
D) It cannot be accomplished, a side constraint must be added.

This approach involves splitting the warehouse node into two nodes, with each node having a capacity of 100. The in-flow arcs of the new warehouse node should be connected to the first node, while the outflow arcs should be connected to the second node. This ensures that the sum of in-flows and the sum of out-flows for the warehouse do not exceed 100, and there is no need to add a side constraint to limit either of them.
