PANDEMİ DÖNEMİNDE YALIN ÜRETİM UYGULAMALARININ ÖNCELİKLENDİRİLMESİ: OTOMOTİV PARÇASI ÜRETİCİLERİ ÖRNEĞİ

Küresel Covid-19 pandemisinin etkisi birçok otomotiv parçası imalatı yapan işletmenin üretimine ara vermesine neden olmuştur. Sürdürülebilir üretimin en iyi araçlarından biri olan yalın üretim bu noktada daha fazla önem kazanmıştır. Hammadde stoğunun azalması yer yer bitmesi üretim sürecinde aksamalara sebebiyet vermiş, müşteri talebinin karşılanamamasına neden olmuştur. Hâlihazırda yalın üretim felsefesini benimsemiş işletmeler yalın uygulamalarına daha çok önem göstermektedir. Bu çalışma da bu süreç içerisinde otomotiv parçası üreten işletmelerin hangi yalın üretim araçlarını öncelikli olarak kullandıklarını tespit etmeye yönelik araştırma yapmıştır. Araştırma yalın üretim araçlarını kullandığını belirten 42 otomotiv parçası üreticisi işletmenin üretim mühendislerini yönelimlerini göstermektedir. Yalın üretim araçlarının bu süreç içerisinde tercih edilmesini yorumlayıcı yapısal model kullanarak açıklayan anket çalışması sonucunda pandemi sürecinde en çok tercih edilen yalın üretim aracının toplam verimli bakım ve hata önleme sistemleri olduğu ortaya çıkmıştır. Bunun nedenleri yorumlandığında boşta duran makinalara bakım yapılacağı ve üretim esnasında olabilecek bir arızada gerekli tamir parçasının tedariğinin geç gelebileceğinden dolayı periyodik bakıma önem verildiğidir. Bir ikinci yalın üretim aracı da hata önleme sistemidir. Süreçlerindeki iyileştirmelerde poke-yoke araçlarını geliştirdikleri ortaya çıkmıştır. Kullanılan modelin işlerliği, pandemi sürecinde otomotiv parçası üretimi yapan işletmelerin üretimi sekteye uğratan durumların önüne geçmesi yönünden hem literatüre hem de sektöre katkı sağlamaktadır.

PRIORITIZATION OF LEAN MANUFACTURING PRACTICES DURING THE PANDEMIC PERIOD: CASE OF AUTOMOTIVE PARTS MANUFACTURERS

The effect of the global Covid-19 pandemic has caused many automotive parts manufacturing companies to suspend their production. Lean production, which is one of the best tools of sustainable production, has gained more importance at this point. The decrease in the stock of raw materials caused disruptions in the production process and the customer demand was not met. Businesses that have already adopted the lean production philosophy attach more importance to lean applications. This study also conducted research to determine which lean production tools primarily used by the companies producing automotive parts during this process. The research shows the orientation of the production engineers of 42 automotive part manufacturer companies that stated that they use lean production tools. As a result of the survey, which explains the preference of lean production tools in this process by using an interpretative structural model, it has been revealed that the most preferred lean production tool in the pandemic process is total efficient maintenance and error prevention systems. The reasons for this are that the idle machines will be serviced and that periodic maintenance is given importance because the supply of the necessary repair part may come late in case of a malfunction that may occur during production. A second lean manufacturing tool is the defect prevention system. It has been revealed that they have developed poke-yoke tools in the improvements in their processes. The operability of the model used contributes to both the literature and the industry in terms of preventing the situations that interrupt the production of the companies that produce automotive parts during the pandemic process..
