Question 1

Preemptive goal programming strives to achieve all of the goals simultaneously.

Accepted Answer

False

Question 2

In weighted goal programming,the target cell is the weighted sum of the deviations from the goals.

Accepted Answer

In weighted goal programming, the target cell is indeed the weighted sum of the deviations from the goals, where each deviation is multiplied by a weight that reflects its relative importance or priority.

Question 3

Goal programming provides a way of striving toward several objectives simultaneously.

Accepted Answer

Goal programming is a method used in operations research for optimizing several objectives at the same time. The approach allows decision-makers to incorporate multiple goals and constraints into a single objective function and then find the best solution that satisfies these criteria to the greatest extent possible.

Question 4

In which of the following situations is preemptive goal programming more appropriate than weighted goal programming?
A)When there are major differences in the importance of the goals.
B)When all of the goals are roughly equal in importance.
C)When there is a single objective or goal.
D)None of the above.
E)b and c only.

Accepted Answer

Preemptive goal programming is more appropriate when there are major differences in the importance of the goals because it allows the most important goals to be achieved first, while still considering the less important goals. Weighted goal programming, on the other hand, assumes that all goals are of equal importance and distributes the deviations from each goal equally.

Question 5

In preemptive goal programming,the goals are ranked from most important to least important.

Accepted Answer

In preemptive goal programming, the goals are ranked from most important to least important in order to determine which goal(s) should be fully achieved and which can be partially achieved or not achieved at all. This ensures that the most important goal(s) are given priority and that decisions are made in a logical and structured manner.

Question 6

Goal programming can be used to handle problems with how many different objectives or goals?
A)1
B)2
C)3
D)4
E)Any number of objectives or goals.

Accepted Answer

Goal programming can be used to handle problems with any number of objectives or goals. The technique allows decision-makers to simultaneously consider and balance multiple objectives, even when these objectives compete or conflict with each other.

Question 7

In preemptive goal programming,if a new solution provides a major improvement in the second goal at the cost of a slight increase in the deviation from the first goal,then the new solution will be chosen.
Multiple Choice Questions

Accepted Answer

In preemptive goal programming, goals are prioritized, and the first goal must be satisfied before considering improvements in lower-priority goals. A solution that worsens the first goal, even slightly, would not be chosen.

Question 8

Goal programming provides a way to identify the most important goal and achieve it.

Accepted Answer

The answer of Goal programming provides a way to identify...

Question 9

In weighted goal programming,the objective is to:
A)Minimize the weighted sum of deviations from the goals.
B)Minimize the deviation from the most important goal.
C)Meet the most important goal.
D)Maximize the profit.
E)None of the above.

Accepted Answer

In weighted goal programming, the objective is to minimize the weighted sum of deviations from the goals. This means that the model will attempt to minimize the overall distance from all the goals, while placing more importance on certain goals that have been assigned a higher weight.

Question 10

A goal programming formulation includes changing cells to measure the amount over and under each goal.

Accepted Answer

In goal programming, the deviation variables are added to measure the amount by which each goal is over or under-achieved. These deviation variables are then minimized in order to achieve a satisfactory solution. So, changing cells are used to measure the amount over and under each goal.

Question 11

In preemptive goal programming,penalty weights are assigned to measure the relative seriousness of missing the respective goals.

Accepted Answer

The answer of In preemptive goal programming,penalty weights are assigned...

Question 12

Goal programming problems cannot be easily reformulated as linear programming problems and,therefore,require a special algorithm to solve.

Accepted Answer

The answer of Goal programming problems cannot be easily reformulated...

Question 13

Penalty weights for goal programming are best measured in monetary terms.

Accepted Answer

The answer of Penalty weights for goal programming are best...

Question 14

Which of the following are changing cells in a goal programming formulation?
A)Activity levels.
B)Deviations from the goals.
C)The weighted sum of deviations.
D)All of the above.
E)a and b only.

Accepted Answer

The changing cells in a goal programming formulation are the activity levels and deviations from the goals. The weighted sum of deviations is not a changing cell but rather the objective function that is being minimized. Therefore, the correct choice is (E) a and b only.

Question 15

In goal programming,constraints are used to assure that every goal is met.

Accepted Answer

The answer of In goal programming,constraints are used to assure...

Question 16

The overall objective for a goal programming problem is to minimize the weighted sum of deviations of the objective functions from their respective goals.

Accepted Answer

This is the correct statement for the overall objective of a goal programming problem. The deviations are weighted based on the importance of each objective and the goal is to minimize the sum of these weighted deviations.

Question 17

In preemptive goal programming,the target cell is the weighted sum of the deviations from the goals.

Accepted Answer

The answer of In preemptive goal programming,the target cell is...

Question 18

Preemptive goal programming is more appropriate the weighted goal programming when there are major differences in the importance of the goals.

Accepted Answer

Preemptive goal programming allows for the most important goals to be achieved first, while weighted goal programming treats all goals equally, making it less effective when there are major differences in importance.

Question 19

In preemptive goal programming,the first step is to:
A)Minimize the weighted sum of deviations from the goals.
B)Minimize the deviation from the most important goal.
C)Meet the most important goal.
D)Maximize the profit.
E)None of the above.

Accepted Answer

Preemptive goal programming aims to minimize the deviation from the most important goal first, before moving on to minimizing deviations from other goals. This approach ensures that the most critical goal is given priority and will be met before addressing the other goals.

Question 20

Weighted goal programming provides a way of striving toward several objectives simultaneously.

Accepted Answer

Weighted goal programming allows individuals or organizations to prioritize multiple goals and allocate resources accordingly to achieve these goals simultaneously. It is a popular approach in decision-making and can be used in various fields such as business, finance, and public policy.
