Which of the following statements concerning the transshipment problem is false?
Any units shipped from one origin point must all go to the same destination point.
In the maximal-flow technique, a zero (0) means
No flow or a one-way arc
The primary difference between PERT and CPM is that
PERT has three time estimates
The shortest-route model assumes that one is trying to connect two end points in the shortest manner possible, rather than attempting to connect all the nodes in the model
True
What is said to exist when total demand equals total supply in a transportation problem?
a balanced problem
The expected time in PERT is
a weighted average of the most optimistic time, most pessimistic time, and four times the most likely time
A line in a network that may represent a path or a route is called a(n)
arc
CPM stands for
critical path network
A line in a network that may represent a path or a route is called a(n)
facility location
Transportation models can be used for which of the following decisions?
facility location
The critical path of a network is the
longest time path through the network
A point in the network, that is at the beginning or end of a route is called a(n)
nodes
PERT stands for
program evaluation and review techniques
The maximal-flow model assumes
that there is a net flow from "source" to "sink."
In PERT, the time estimate b represents
the most pessimistic time
Slack time in a network is the
time an activity can be delayed without delaying the entire project
The maximal-flow technique would best be used
to maximize traffic flow on a busy highway
Network models such as PERT and CPM are used
to monitor, plan, & schedule
The two most common objectives for the assignment problem are the minimization of
total cost or total time
The two most common objectives for the assignment problem are the minimization of
total costs or total time
Before drawing a PERT or CPM network
we must identify all activities and their predecessors
The first step in planning and scheduling a project is to develop the
work breakdown structure
