Abstract: | This study deals with the problem of supplier-material selection as well as production
planning in carton box production industries. The initial step in solving these problems
is to deal with the cutting problem which refers to the problem of dividing a usually
large piece of the rectangular raw materials into smaller pieces for producing various
products. Dealing with this problem is at the stake of dealing with the uncertainties
related to the environment of the problem in most cases. A critical problem arises when
size, amount, and suppliers of the raw materials have an uncertain nature from the
price point of view. In such cases, selecting the correct size and quantity of the raw
material as well as right suppliers are the crucial elements for a competent production.
In this research, a model reflecting the nature of the problem is proposed and a new
solution approach is employed for solving it. Moreover, the problem’s related
uncertainties are incorporated to the original problem through utilizing the fuzzy
variables. The new problem then is solved with different fuzzy methods. The
mentioned approaches are verified through implementaion on a newly established
company which produces carton boxes for various manufacturers. These carton boxes
must meet a very accurate specification related to their material type and dimension
congruous with their purchaser’s requirements. The objective is to optimizing the
production procedure and defining an efficient production system as one of the
essential requirements for sustainability of the production within this company. In the
following chapters, all of the steps are discussed in detail.

Bu çalışmada karton kutu üretim sanayisi için tedarikçi-malzeme seçimi problemi ve
üretim planlama çalışmaları ele alınmıştır. Bu problemlerin çözümündeki ilk aşama
genellikle büyük boyutlu dikdörtgen şeklindeki hammaddeleri çeşitli ürünlerin
üretilmesi için küçük parçalar halinde kesme probleminin çözülmesidir. Bu problemin
çözümü çoğu durumda problemle ilgili belirsizliklerle uğraşmayı gerektirmektedir.
Ölçü, miktar ve hammade tedarikçilerinin belirsizlik ortamında olması fiyatla ilgili
kritik bir problemin ortaya çıkmasına sebep olur. Böyle durumlarda, hammaddeyle
iligi doğru ölçü, mikrat ve de tedarikçi seçimi rekabetçi üretimin önemli etkenleridir.
Bu çalışmada, problemin bir modeli önerilmiş ve yeni bir çözüm yöntemi
uygulanmıştır. Dahası, problemle ilgili belirsizlikler bulanık değişkenler kullanarak
orijinal probleme dahil edilmiştir. Bu yeni problem farklı bulanık yöntemler
kullanılarak çözülmüştür. Bahsi geçen yaklaşımlar daha sonra çeşitli imalatçılar için
karton kutu üreten yeni bir şirket için uygulanarak doğrulanmıştır. Bu karton kutular
müşterilerin gereksinimlerine uygun olarak hammade tipi ve boyutlarla ilgili çok kesin
özellikleri sağlamalıdır. Amaç, bu şirket için üretimin devamlılığyala ilgili temel
ihtiyaçlardan biri olarak üretim işlemini en iyilemek ve etkili bir üretim sistemi
tanımlamaktır. İzleyen bölümlerde tüm aşamalar detaylı bir şekilde anlatılmıştır.
