An integrated supplier selection and order allocation approach in a battery company

Firmalar, ihtiyaç duydukları dolaylı ve dolaysız malzemeleri ve bileşenleri temin edebilmek için tedarikçilerle çalışmak zorundadır. Bu yüzden satın alma kararları firmalar için çok önemlidir. Hangi firmadan ne kadar malzeme alınacağı sorusu, her firmanın karşılaştığı temel tedarikçi seçimi problemidir. Bu problemlerde karar vericinin göz önüne alması gereken birden çok faktör vardır. Tedarikçi seçimi nitel ve nicel faktörleri içeren çok kriterli bir karar verme problemidir. Kapasite kısıtı olduğu zaman, tedarikçi seçimi problemi daha karmaşık hale gelir. Bu durumda, satın almacı hangi tedarikçi daha iyi olduğu ve her seçilen tedarikçiden ne kadar alınmalı problemleri hakkında karar vermek zorundadır. Bu çalışmanın amacı, bir akü üretim firmasında tedarikçi seçimi ve sipariş miktarlarının belirlenmesi problemini çözmektir. Çalışma kapsamında, nicel ve nitel faktörleri göz önüne alarak en iyi tedarikçiyi seçmek ve buna göre optimum sipariş miktarlarını belirlemek için analitik hiyerarşi sürecini ve hedef programlamayı temel alan bir yaklaşım önerilmiştir.

Bir akü firmasında bütünleşik tedarikçi seçimi ve sipariş miktarı belirleme yaklaşımı

Firms should work with suppliers in order to provide direct and indirect materials and components. Thus, purchasing decision is very important in a firm. The question of “who to buy from and how much” is simply the supplier selection problem that every firm faces. In this problem, there is more than one concern that the decision maker needs to deal with. Hence, supplier selection is a multi-criteria problem which includes both tangible and intangible factors. When capacity constraints exist, this problem becomes more complicated as, in these circumstances, purchasers should decide about two issues: “which suppliers are the best” and “how much should be purchased from each selected supplier”. The aim of this study is to solve the supplier selection and order allocation problem of a battery company. In the scope of the study, an integrated approach based on analytical hierarchy process and goal programming is proposed to consider both tangible and intangible factors in choosing the best suppliers and placing the optimum order quantities among them.
