AB  - Short and reliable lead times areimportant to promote customer satisfaction and generate further orders,particularly in the case of make-to-order and engineer-to-order manufacturing.Moreover, accurate manufacturing lead times can greatly help productionplanning and allocation of capacities. The design of a manufacturing systemrefers to the configuration of elements such as the number of workstations,storage, capacity and movement of work through the system. The design of amanufacturing system can play a key role in manufacturing lead time. Thepurpose of this paper is to investigate the effects of the number ofworkstations, buffer sizes, processing capacities, number of entry workstationsand layout of a system on manufacturing lead time, and to demonstrate how suchan analysis can aid managerial decision making in production planning. Fivesets of experiments, with a total of 19 cases, were conducted. An approximatemodel for arbitrary queueing networks is used to provide insights into thegeneral behaviour of manufacturing systems. These experimental results suggestthat the manufacturing lead time of a system is the most sensitive to layout ofthe system, i.e., configuration of the system (feed-forward or feed-backwardtopology) and the number of exit workstations.

N2  - Kısave güvenilir temin süreleri, özellikle siparişe-özel-üretim vesiparişe-özel-tasarım şeklinde üretim yapan firmalarda müşteri memnuniyetiniartırmak ve siparişlerde süreklilik sağlamak için kritik önem taşımaktadır. Ayrıcakesin ve güvenilir üretim temin süreleri, üretim planlamasına ve kapasitetahsisine önemli ölçüde katkı sağlamaktadır. Bir üretim sisteminin tasarımı işistasyonu sayısı, bekleme alanlarının büyüklüğü, üretim kapasitesi ve işlerinsistem içindeki rotaları gibi unsurların yapılandırılmasını kapsamaktadır. Üretimsistemi tasarımı, temin süresinin belirlenmesinde önemli rol oynamaktadır. Buçalışmanın amacı, iş istasyonu sayısının, iş istasyonları arasındaki tamponalanlarının büyüklüğünün, üretim kapasitesinin, giriş iş istasyonu sayısının vesistemin yerleşim planının üretim temin süresi üzerindeki etkilerini araştırmakve böyle bir analizin üretim planlamasında yönetimsel karar almaya nasıl yardımedebileceğini göstermektir. Çalışmada, 19 vakanın bulunduğu beş ayrı gruptadenemeler gerçekleştirilmiştir. Üretimsistemlerinin performanslarının belirlenmesinde yapılandırılmamış kuyruk ağlarıiçin geliştirilen yaklaşık bir model kullanılmıştır. Deneme sonuçları üretimtemin süresinin, sistemin yerleşim planından (sistemin yapılandırmasının ileriveya geri beslemeli oluşu ve çıkış iş istasyonlarının sayısından) önemli ölçüdeetkilendiğini göstermektedir.
