Production planning is one of the most important functions in the process of production management.\nProduction planning in the intermediate range of time is termed as ââ?¬Å?aggregate production planning (APP)ââ?¬Â.\nAggregate production planning is an important upper level planning activity in a production management\nsystem. The present study tries to suggest an aggregate production planning model for products of Hafez\ntile factory during one year. Due to this fact that the director of the company seeks 3 main objectives to\ndetermine the optimal production rate, the linear goal planning method was employed. After solving the\nproblem, in order to examine the efficiency and the distinctiveness of this method in compare to linear\nprogramming, the problem was modeled just by considering one objective then was solved by linear\nprogramming approach. The findings revealed the goal programming with multi objectives resulted more\nappropriate solution rather than linear programming with just one objective.
