QUESTION 11 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
