BIT 3434 Exam 2 Study Guide Questions With100% Accurate Answers
the transshipment problem - Answer is the most general type of network flow problem
the arcs in a network indicate - Answer the valid paths, routes, or connections between
the nodes in a network flow problem
the net supply for each node in the network is indicated by - Answer a negative number
next to each node
A transshipment node can have - Answer either a net supply or demand, but not both
In a transshipment problem formulation, the decision variables are of the form - Answer
Xij, which is the number of items shipped (or flowing) from node i to node j
The objective in most network flow problems is to - Answer minimize total cost, distance
or penalty that must be incurred to solve the problem
balance of flow constraints - Answer define a relationship between inflow and outflow
for every node in a network
a problem in which we want to find the shortest (or least costly) route or path through a
network from a starting node to an ending node is called - Answer the path problem
in a typical path problem, the supply node flor constraint RHS is equal to - Answer -1
If you use the simplex method to solve any minimum cost network flow model having
, integer constraint RHS values, then - Answer the optimal solution automatically
assumes integer values
The equipment replacement problem is a type of problem that can be modeled as a -
Answer shortest path problem
Any shortest path problem can be modelled as a transshipment problem bby - Answer
assigning a supply of 1 to the starting node, a demand of 1 to the ending node and a
demand of zero to all other nodes in the network
a transportation problem - Answer is a special case of transshipment problem
Suppose you want to determine the minimum cost of shipment using a transportation
problem formulation. Further, you do not want to send any shipment from source i to
destination j. When modeling this situation you should - Answer assign a large cost, cij=
M, to the shipment quantity, Xij between source i and destination j
Consider a transportation problem in which total demand exceeds total supply. In order
for such a problem to be in standard form, you would add a dummy supply whose
capacity equals the difference between total demand and total supply. See "dummy
nodes and arcs" in chapter 5 for more information.
you want to assign m jobs to n machines to minimize the assignment total cost. you
model this problem as an assignment problem in a standard form. In your formulation: -
Answer all constraints RHS are strictly equal to 1
the objective function in a minimal spanning tree problem is to - Answer determine the
set of arcs that connect all the nodes in the network
what is the correct constraint for the following diagram - Answer x12 +x13 >= 50
what is the constraint for node 3 in the following shortest path problem - Answer
-x13+x34=0
