Abstract

Amaç: Bu çalışma, süreç esnekliği varsayımında farklı esneklik yapılarının işletmelerde üretim-envanter kararlarını ve ilgili operasyonel maliyetleri nasıl etkilediğini incelemektedir. Çalışmanın amacı, süreç esnekliği probleminde optimal sistem tasarımı kararlarının bulunması ve bu kararların envanter maliyetleriyle ilişkisinin incelenmesidir.

Yöntem: Çalışma kapsamında; planlama ufku boyunca envanter maliyetlerini ve esneklik yatırımlarının amortismanını içeren problem, karma tam sayılı doğrusal programlama ile modellenerek çözülmüştür.

Bulgular: Sunulan model kullanılarak, optimum envanter, üretim ve sistem tasarımı kararları verilmiştir ve planlama ufku boyunca karşılık gelen maliyetler hesaplanmıştır. Yapılan analizler çalışmada sunulan modelden elde edilen optimal tasarımın, literatürde geleneksel esneklik tasarımları içerisinde en düşük ortalama maliyetleri sağlayan ikili zincir tasarımından dâhi daha iyi sonuç verdiğini göstermiştir.

Özgünlük: Bildiğimiz kadarıyla, bu çalışma literatürde envanter ve yatırım maliyetlerini içeren ve optimal esneklik tasarımlarını operasyonel maliyetler açısından değerlendiren ilk çalışmadır.

Abstract

Purpose: This study examines how different flexibility structures affect production-inventory decisions and related operational costs in enterprises. The aim of the study is to find the optimal system design decisions in the process flexibility problem and to examine the relationship between these decisions and inventory costs.

Methodology: We propose a mixed integer linear programming model, which includes inventory costs and depreciation of flexibility investments across the planning horizon.


Findings: In this model, optimum inventory, production, and system design decisions are made and corresponding costs are calculated over the planning horizon. The analyzes show that the model presented in the study gives even better results than the two-chain design, which provides the lowest average costs among the traditional flexibility designs in the literature.

Originality: To the best of our knowledge, this is the first study to evaluate optimal flexibility designs in terms of operational costs, including inventory and investment costs.
