Abstract

The study focuses on optimizing the production process of a Turkish family company specializing in seat belt manufacturing, boasting an annual capacity of 810,000 units and employing 150 individuals. Serving major clients such as Otokar, Ford Otosan, Bmc, Karsan, Anadolu Isuzu, Mercedes, Man, Temsa, and Türk Traktör, the company utilizes pressing, plastic injection, and assembly lines in its production. With a specific emphasis on the sequencing and scheduling of the assembly lines, a mathematical model was formulated and solved using GAMS software. Comparative analysis, incorporating scenario assessments, revealed that the proposed model significantly enhanced efficiency compared to various scenario outcomes.

Keywords

Sequence and scheduling, assembly line, unfinished works, ERP (enterprise resource planning), APP (aggregate production planning)

SEQUENCING MODEL FOR A SEAT BELT MANUFACTURER

Abstract

Ticari araç sektörüne yönelik emniyet kemeri ve yedek parça üretimi gerçekleştiren, yılda 810.000 emniyet kemeri üretebilen aile şirketi, müşterileri arasında Otokar, Ford Otosan, Bmc, Anadolu Isuzu, Mercedes, Man, Temsa, Türk Traktör gibi önemli markaları bulundurmaktadır. Firmanın üretim kapasitesi, pres, plastik enjeksiyon ve montaj hatlarından oluşmaktadır. Şirketin üretimini geliştirmek amacıyla emniyet kemeri montaj hatlarının sıralanması ve programlanmasını ele almaktadır.
Şirketin 3 adet emniyet kemeri montaj hattı bulunmaktadır. Sıralama ve çizelgeleme sorununu çözmek için matematiksel bir model geliştirilmiş ve model GAMS yazılımı kullanılarak çözülmüştür. Çalışmanın sonuçları, GAMS modelindeki tamamlanmamış senaryo analizlerinin karşılaştırmasıdır. Önerilen modelin sonuçları, farklı senaryo analizlerine dayalı sonuçlarla kıyaslandığında, önerilen modelin daha etkili sonuçlar elde ettiğini göstermektedir.
