BUSOBA 2321 FINAL EXAM 2025
Network Models - ANSWER propose a web-like organization of ideas in
memory, with numerous interlinks
Node - ANSWER A specific point or location in a network
Origins - ANSWER a location that produces commodities (factory)
(Supply point, source node)
Destinations - ANSWER a location that consumes commodities (retail outlet)
(Demand point, sink node)
Transshipment - ANSWER a point at which products are transferred from or to
other points
Arc - ANSWER Connects two nodes to each other
One way (Undirectional) or two way (bidirectional) - ANSWER Arcs can be in
what direction?
capacitated; uncapacitated - ANSWER Arcs can be _____ (limited flow) or
________ (unlimited flow)
fully connected - ANSWER When arcs are __________ they can exist between
every pair of nodes in a network
circles; lines - ANSWER Nodes are ______ and arcs are _______
undirectional - ANSWER Decision Variables represent the amounts of flows or
shipments that occur on _________ arcs in the network
, Flow balance constraints - ANSWER calculate the net flow at each node
Net Flow = (Total Flow into Node) - (Total Flow out of Node) - ANSWER Net
Flow Formula:
Exceed - ANSWER Total flow out of the node will ________ the total flow in
to the node
Net Flow - ANSWER The ________ indicates goods created (supply) at the
origin
Negative Quantities - ANSWER Supply values are expressed as ___________
Transshipment Node - ANSWER Goods are neither produced nor consumed at
a pure ___________
Flow out - ANSWER Total flow in to the node will be equal to the total
________ of the node
0 or 1 - ANSWER All flow balance constraint coefficients are either _______
1 ; 0 - ANSWER If a decision variable is present in a constraint, the coefficient
is _______, otherwise it is _______
Total flow in < Total flow out Creator of goods RHS Negative
Supply point
Total flow in > Total flow out Consumer of goods RHS Positive
Demand point
Total flow in = Total flow out Pure transshipment RHS = 0
point - ANSWER Flows in transshipment models can happen both in and out of
the same node in three ways:
Ranked Goals Approach - ANSWER Give ranks or priorities to goals
