The textile and apparel sector are considered as one of the fastest growing sectors in our country. This sector plays a vital role for the economic growths of Malaysia either in the short term of period or long term of period. Textile industry will continue to be relevant in the future years as more emphasis is immediately devoted to serve the demands of the niche markets and upstream activities. Hence, companies involved in this industry must have a proper production plan for success. Planning a business plays a significant role in the success of a production system where planning should consider the limitation of resources such as labor, ma¬ chine usage, time and budget. Textile and apparel companies dealt with many objectives in their production planning such as to minimize the total production cost, to maximize the total sales income and to minimize the use of raw materials. Therefore, this research will apply a goal programming method to achieve all objectives of the production planning simultaneously. This research presents a goal programming model for the optimization of production planning for a boutique in Senawang, Seremban. Then, LINGO Software is then being used to test the model. The result of the preemptive model is then compared to the previous data of the last Eid al-Fitr season by using the weighted Means Absolute Percentage Error (MAPE). The result shows that the objectives were fully achieved and this proves that goal programming approach is a useful tool and can be used to solve the textile and apparel production planning problem as well as other multi-objective problems.
