Question

The assignment problem is a special case of the transportation problem where

• A. Supply and demand are unlimited
• B. Each source supplies exactly one unit and each destination demands exactly one unit
• C. Costs are always zero
• D. The number of sources exceeds destinations

Hint:

Assignment problem: \[ \boxed{ \text{Supply} = \text{Demand} = 1 } \] for every source and destination.

Answer 1

The Correct Option is B

Step 1: Recall the assignment problem. The assignment problem is a special form of the transportation problem in which each source can be assigned to only one destination and each destination requires exactly one source.

Step 2: Identify the defining condition. Thus, \[ \boxed{ \text{Each source supplies one unit and each destination demands one unit.} } \] Hence, \[ \boxed{(B)} \] is the correct answer.
