Goal programming and linear programming differ in that
A)in LP,the objective function is maximized or minimized,while in goal programming,the deviation between goals and possible achievement is minimized.
B)slack variables are used in LP,while deviational variables are used in goal programming.
C)deviational variables have positive objective function coefficients in goal programming,but slack variables have 0 coefficients in LP.
D)All of the above
E)None of the above

Question

Quizplus · Accepted Answer

A) This is true for both LP and goal programming.
B) Slack variables are used in LP to convert inequality constraints to equality constraints, while deviational variables are used in goal programming to measure the deviation between goals and possible achievement.
C) This is true for both LP and goal programming. In LP, the coefficients of slack variables are always 0, while in goal programming, the coefficients of deviational variables are positive. 
Therefore, the best choice is D, as all of the options are true.

Note: This question provides a good overview of the differences between LP and goal programming, especially in terms of variables used and objective function coefficients.
