AB  - Demand forecasting and production planning are the main planning issues in industry. Poor forecasting and ineffective production planning procedures result in either excess inventories or unmet demand. In either case company faces with excessive losses. Over the past century, scientific management principles have been highly developed and can be used to solve these problems. However, many companies either lack engineering and management knowledge in this respect or are careless in applying already available forecasting and planning tools. This study presents a case application which illustrates the use of available management tools and shows how a significant amount of cost savings can be achieved by just applying basic tools and procedures. The paper can be useful for practicing engineers and production planning managers in future applications.

N2  - Talep tahmini ve üretim planlaması, endüstrideki ana planlama konularıdır. Yetersiz tahmin ve etkisiz üretim planlama prosedürleri, ya fazla stokla ya da karşılanmayan taleple sonuçlanır. Her iki durumda da şirket aşırı kayıplarla karşı karşıyadır. Geçen yüzyılda, bilimsel yönetim ilkeleri oldukça gelişmiştir ve bu sorunları çözmek için kullanılabilir. Ancak, birçok şirket bu konuda ya mühendislik ve yönetim bilgisinden yoksundur ya da halihazırda mevcut olan tahmin ve planlama araçlarını uygulamada dikkatsizdir. Bu çalışma, mevcut yönetim araçlarının kullanımını gösteren ve sadece temel araç ve prosedürleri uygulayarak önemli miktarda maliyet tasarrufunun nasıl sağlanabileceğini gösteren bir vaka uygulaması sunmaktadır. Kağıt, gelecekteki uygulamalarda mühendisler ve üretim planlama yöneticileri için yararlı olabilir.
