ANSWER: c

1. A factory that ships items through the network would be represented by which type of node?
   1. demand
   2. supply
   3. random
   4. decision

ANSWER: b

1. A node that can both send to and receive from other nodes is a
   1. demand node.
   2. supply node.
   3. random node.
   4. transshipment node.

ANSWER: d

1. Demand quantities for demand nodes in a transshipment problem are customarily indicated by

   3. imaginary numbers.
   4. either positive or negative numbers.

ANSWER: a

1. Decision variables in network flow problems are represented by
   1. nodes.
   2. arcs.
   3. demands.
   4. supplies.

ANSWER: b

7.The number of constraints in network flow problems is determined by the number of

1. nodes.
2. arcs.
3. demands.
4. supplies.

ANSWER: a

1. How many constraints are there in a transshipment problem that has n nodes and m arcs?
   1. n
   2. m
   3. (n + m)
   4. (m − n)

ANSWER: a

1. In a transshipment problem, which of the following statements is a correct representation of the balance-of-flow rule if Total Supply < Total Demand?
   1. Inflow − Outflow ≥ Supply or Demand
   2. Inflow + Outflow ≥ Supply or Demand
   3. Inflow − Outflow ≤ Supply or Demand
   4. Inflow + Outflow ≤ Supply or Demand

ANSWER: c

1. Supply quantities for supply nodes in a transshipment problem are customarily indicated by
   1. positive numbers.
   2. negative numbers.
   3. imaginary numbers.
   4. either positive or negative numbers.

ANSWER: b
