J.
Satisfy rim conditions
K.
Prevent solution from becoming degenerate
L.
Ensure that total cost does not exceed a limit M. None of the above

. The occurrence of degeneracy while solving a transportation problem means that
60.
An alternative optimal solution to a minimization transportation problem exists whenever
opportunity cost corresponding to unused route of transportation is:
R.
Positive & greater than zero
S.
Positive with at least one equal to zero

One disadvantage of using North-West Corner rule to find initial solution to the
transportation problem is that
62
. The solution to a transportation problem with ‘m’ rows (supplies) & ‘n’ columns
(destination) is feasible if number of positive allocations are
A.
m+n
B.
m*n
C.
m+n-1
D.
m+n+1

. If an opportunity cost value is used for an unused cell to test optimality, it should be
64.
During an iteration while moving from one solution to the next, degeneracy may occur when
65.
The large negative opportunity cost value in an unused cell in a transportation table is
chosen to improve the current solution because
