BİR TEKSTİL ŞİRKETİ İÇİN ÜRETİM HATTI ATAMA PROBLEMİ

Bu çalışmada, üretim planlaması elle yapılan Karaman Tekstil'in üretim süreci gözlemlenmiş ve analiz edilmiştir. Bu çalışma, bir karma tamsayılı programlama modeliyle, senaryolar geliştirerek ve sonuçları GAMS yazılımı ile elde ederek mevcut sistemin kullanılmayan makine kapasitesini ve boşta kalma süresini en aza indirmeyi amaçlamaktadır. Ayrıca, üretim sürecinin verimliliğini karşılayan ve maksimize eden optimal sonuca ulaşmak için senaryoların sonuçları karşılaştırılmakta ve değerlendirilmektedir. Şirketin olağan üretim planlaması elle yapılmakta ve yıllık talebe göre belirlenmektedir. Çalışma, makine çalışma sürelerinin en aza indirilmesini ve üretim planlamasının optimal şekilde tamamlanmasını amaçlamaktadır. Bu çalışmada, firmanın üretim süresi ve makine kullanım süreleri optimize edilmiş olup, normal şartlar altında, günde 8 saat, haftada 5 gün ve ayda 4 hafta olmak üzere 15.000 kumaş pantolon üretilmiştir. Senaryo analizi, ilk senaryoda 15.000 adet kumaş pantolona ek olarak 4.000 adet kadife pantolon eklenerek üretilmesi hedeflenmiştir. İkinci senaryoda ise şirkete ait makinelerin çalışma sürelerinin sınırlandırılarak 15.000 kumaş pantolon üretim süresinin en aza indirilmesi planlanmıştır.

A PRODUCTION LINE ASSIGNMENT PROBLEM FOR A TEXTILE INDUSTRY

In this study, the production process of Karaman Textiles, for which production planning is done manually, was observed and analyzed. This study aims to minimize the unused machine capacity and idle time of the existing system by developing a mixed integer programming (MIP) model, developing scenarios, and obtaining the results with GAMS software. In addition, the results of the scenarios are compared and evaluated to reach the optimal result that meets and maximizes the efficiency of the production process. The company's usual production planning is done manually and determined according to annual demand. The study aims to minimize the machine working times and that complete planning of the production in the most optimal way. In this study, the company's production time and machine usage times were optimized, and under normal conditions, 15,000 fabric pants were produced for 8 hours a day, 5 days a week, and 4 weeks a month. The scenario analysis aimed to produce by adding 4,000 pieces of velvet pants in addition to 15,000 fabric pants in the first scenario. The second scenario aims to minimize the production time of 15,000 fabric pants by limiting the working times of the machines owned by the company.
