In assignment problem each job requires
► Exactly one resource
► At least one resource
The dual of the dual problem yields the original primal
► True
An unrestricted primal variable will result in an equality dual constraint.
► True
The formula for expected number of customers in a system is
o L = λ /(µ - λ)
o L = λ /(λ - µ)
o L = µ /(λ - µ)
o L = µ /(µ - λ)
In two dimensional LP problem we need only two lines to identify an extreme point. If in any two dimensional problem there are three or more intersecting lines at the corner point then this indicate that
o Problem has Degenerate Solution
o One of the constraints is redundant
o Both First and Second
o None of the above
