Process
flexibility in manufacturing aims to produce different products at the same
production facility with the minimum setup cost. It is not possible to
completely eliminate the setup cost in most cases even if a high degree of
investment is made for process flexibility. In this study, a decision support
model accounting for fixed setup cost has been presented to make inventory
decisions in production systems that have process flexibility. Additionally,
under process flexibility, the effect of fixed setup cost on inventory
decisions has been investigated. In this context, process flexibility problem
with fixed setup cost has been modelled using Mixed Integer Linear Programming
approach. Numerical assessments have been done on three different production
systems (dedicated, two chain and flexible) by means of the proposed decision
support model. The results reveal the necessity of taking fixed setup cost into
account in decision support models for process flexibility problem.

Üretimde
süreç esnekliği, farklı ürünlerin minimum hazırlık maliyetiyle aynı üretim
tesisinde üretilmesini hedeflemektedir. Sabit üretim hazırlık maliyetinin
tamamen ortadan kalkması süreç esnekliği için yüksek seviyede yatırım yapılsa
bile, pek çok durumda mümkün değildir. Bu çalışmada, süreç esnekliğine sahip
sistemlerde stok kararlarının verilmesi için sabit hazırlık maliyetlerini
dikkate alan bir karar destek modeli sunulmuş ve sabit hazırlık maliyetlerinin
süreç esnekliğinde stok kararlarına etkisi araştırılmıştır. Bu çerçevede süreç
esnekliği problemi sabit hazırlık maliyeti göz önünde bulundurularak, karma tam
sayılı doğrusal programlama yöntemiyle modellenmiştir. Geliştirilen bu karar
destek modeli kullanılarak esnek olmayan, ikili zincir tasarımlı ve tam esnek
olmak üzere üç farklı üretim sistemi üzerinde değerlendirmeler yapılmıştır.
Elde edilen sonuçlar süreç esnekliği problemi için geliştirilen karar destek
modellerinde sabit üretim hazırlık maliyetinin göz önünde bulundurulmasının
gerekliliğini ortaya çıkarmaktadır.
