Abstract

Firms must develop and implement effective inventory policies that
minimize costs and maximize profits in today's market conditions where
extraordinary competition is experienced. Inventory has an important place in
the total assets of manufacturing enterprises. Implementation of effective
inventory management policies for this important item is crucial for the future
of firms. Firms can meet customer needs more effectively by controlling fewer
inventories that they classify according to their importance level. In this
study, which is prepared by taking advantage of this point of view, application
is presented that applies multi-criteria decision-making methods to determine
the most important product in terms of inventory management. In the process of
determining the product in the most important according to criteria determined,
AHP method which is frequently used in the literature is applied for
calculation weights of criteria. These weights are used in TOPSIS and VIKOR
methods and results of these two methods are compared.

Envanter Yönetimi Açısından Ürün Seçiminde AHP-TOPSIS ve AHP-VIKOR Yöntemlerinin Karşılaştırılması

Abstract

Firmalar, olağanüstü rekabetin yaşandığı günümüz pazar koşullarında
maliyetleri en aza indirgeyen ve kârları en üst düzeye çıkaran etkili envanter
politikaları geliştirmeli ve uygulamalıdır. Envanterler, imalat işletmelerinin
toplam varlıklarında önemli bir yere sahiptir. Bu önemli kalem için etkin
envanter yönetimi politikalarının uygulanması, firmanın geleceği için çok
önemlidir. Firmalar, önem seviyelerine göre sınıflandırdıkları envanteri
kontrol ederek müşteri ihtiyaçlarını daha etkin bir şekilde karşılayabilirler.
Bu bakış açısından yararlanılarak hazırlanan bu çalışmada, envanter yönetimi
açısından en önemli ürünü belirlemek için çok kriterli karar verme yöntemlerini
uygulayan bir uygulama sunulmuştur. Belirlenmiş kriterlere göre en önemli ürünü
belirleme sürecinde kriterlerin ağırlıklarının hesaplanması için literatürde
sıkça kullanılan AHP yöntemi uygulanmıştır. Bu ağırlıklar TOPSIS ve VIKOR
yöntemlerinde girdi olarak kullanılmış ve alternatifler sıralanmıştır.
