Abstract
Goal programming is a technique often used in engineering design activities primarily to find -
promised solution which will simultaneously satisfy a number of design goals. In solving goal program-
ming problems, classical methods reduce the multiple goal-attainment problem into a single objective of
minimizing a weighted sum of deviations from goals. Moreover, in tackling non-linear goal programming
problems, classical methods use essive linearization techniques, which are sensitive to the chosen
starting solution. In this paper, we pose the goal programming problem as a multi-objective optimization
problem of minimizing deviations from individual goals. This procedure eliminates the need of having ex-
tra constraints needed with classical formulations and also eliminates the need of any user-defined weight
factor for each goal. The proposed technique can also solve goal programming problems having non-
convex trade-off region, which are difficult to solve using classical methods. The efficacy of the proposed
method is demonstrated by solving a number of non-linear test problems and by solving an engineering
design problem. The results suggest that the proposed approach is an unique, effective, and most practical
tool for solving goal programming problems.

1 Introduction
Developed in the year 1955, goal programming method has enjoyed innumerable applications in engineering
design activities
. Goal programming is different in concept from non-linear programming or optimization
techniques in th
