• m * n

• m + n

• m + n - 1

Vogel's Approximation method is connected with

• Assignment Problem

• Inventory Problem

• Transportation problem

• Network problem

The supply at three sources is 50, 40 and 60 units respectively whilst the demand at four destinations is 20, 30, 10 and 50. In solving this transportation problem:

• A dummy source of capacity 40 is needed

• A dummy destination of capacity 40 is needed

• No solution exists as problem is infeasible

• No solution exists as problem is degenerate

The supply at three sources is 80, 30 and 40 units respectively whilst the demand at four destinations is 20, 30, 25 and 55. In solving this transportation problem:

answer choices

• A dummy source of capacity 20 is needed with unit transportation cost one

• A dummy destination of capacity 20 is needed with unit transportation cost zero

• A dummy source of capacity 20 is needed with unit transportation cost zero

• A dummy destination of capacity 20 is needed with unit transportation cost one

The transportation model in operations research is used to solve problems related to:

• Inventory management

• Production scheduling

• Distribution and logistics

• Quality control

1. The transportation model assumes that:

• 1. Demand and supply are equal

• 1. Demand is greater than supply

• 1. Supply is greater than demand

• 1. Demand and supply are unrelated

1. In the transportation model, if the total supply exceeds the total demand:

• 1. Artificial demand is introduced

• 1. Artificial supply is introduced

• 1. The surplus supply is discarded

• 1. The surplus demand is discarded

1. The transportation problem can be solved using:

• 1. The simplex method

• Vogel Approximation method

• 1. The transportation algorithm

• 1. The Hungarian method
