Abstract

This
study focuses on the basic concepts of supply and demand balance, capacity,
economies of scale and scope, theoretical and practical integrated research
problems, solution possibilities and techniques.in the production processes,
supply chain, combined transport main services processes.

The study
investigated medium and long-term capacity and scale economies, supply and
demand balance fluctuations, requirements and qualifications, possible
variations of production, the techniques of economically describing and
determining, economies of scale and scope. Economies of scale and scope compliance
levels of companies in Turkey was searched by the information gathering form
organized within the scope of the study. It was found that scale and scope
economies are higher in companies operating in the field of logistics than manufacturing
firms and It was determined that the firms had development areas to increase
the economies of scale and scope levels. It is clear that average demands in
long-run business sub-processes have emerged under the capacity of scale
economies. This way of working was dealt with based on diversity of operating
production due to fluctuations in demand and on reducing the idle capacity and
reducing the average unit costs. The study investigated relations between
opportunity cost, unit average cost, linear programming and break-even
techniques integrated in the direction of the method of determining production
varieties. It has been seen that the logistics, upstream and downstream
services of the supply chain processes should be advanced in the direction of
marketing researches, the possibilities of optimum economies of scale and scope
economies.

Abstract

Bu çalışma üretim süreçlerinde,
tedarik zinciri, kombine taşımacılık ana hizmetleri süreçlerinde arz ve talep
dengesi, kapasite, ölçek ve kapsam ekonomisi temel kavramlarına, teorik ve
pratik bütünleşik araştırma sorunlarına, çözümleme olanaklarına ve tekniklerine
odaklıdır.

Çalışma orta ve uzun dönemli
kapasite ve ölçek ekonomisi büyüklüklerini, arz ve talep dengesi dalgalanmalarını,
gerekliliklerini ve yeterliliklerini, olanaklar doğrultusunda üretim çeşitliliklerini,
ölçek ve kapsam ekonomisini ekonomik olarak tanımlama ve belirleme tekniklerini
araştırdı. Çalışma kapsamında düzenlenen bilgi toplama formu ile Türkiye’deki
firmaların ölçek ve kapsam ekonomisi uygunluk düzeyleri araştırıldı. Lojistik
alanında faaliyet gösteren firmalarda ölçek ve kapsam ekonomisinin, mal üretimi
yapan firmalara göre daha yüksek düzeyde olduğu, firmaların ölçek ve kapsam
ekonomisi düzeylerinin artırılması yönünde gelişme alanlarının olduğu tespit
edildi. Uzun dönemli işletme alt süreçlerinde ortalama taleplerin ölçek
ekonomileri kapasitesi altında ortaya çıktığı açıktır. Bu yönde çalışma yöntemi,
talep dalgalanmalarına bağlı işletme üretim çeşitlilikleri ile atıl kapasiteyi
azaltma, ortalama birim maliyetleri azaltma temelli olarak ele alındı. Üretim
çeşitliliklerini belirleme yöntemi doğrultularında fırsat maliyeti, birim
ortalama maliyeti, doğrusal programlama ve başa baş tekniklerini bütünleşik
olarak ele aldı ilişkilerini araştırdı. 
Lojistik, tedarik zinciri süreçlerinin alt ve üst hizmetlerinin,
pazarlama araştırmalarının, optimum ölçek ve kapsam ekonomileri olanakları
doğrultularında ilerletilmeleri gerektiği görüldü.
