Abstract

Waiting line problems are defined based on a community of people, machines and materials waiting for a process to be performed. In the solution of the problems related to the waiting line, data such as arrival source, queuing process, service channel and service delivery process in regard to the system are used. According to the structure of the problems of enterprises, waiting line model is formed and calculations such as waiting for service and service time in the queue are made. Since the service speed of all channels is considered to be equal in the wait line models in the literature, it is not possible to determine to what extent each service channel affects the total wait time. In this study, a new approach was introduced to determine to what extent each service channel affects the total waiting time on the waiting line. For this purpose, waiting time is calculated by weighting the system units with the multi-criteria decision-making techniques. The results obtained with the current queuing theory are compared with the results obtained according to the new approach presented in the study. The results obtained in the study; the differentiation of the service speed of service channels has led to more realistic results and it has been determined which service channel has more effect on waiting times. According to the results obtained with the new method, suggestions have been offered in regard to which service channels should be prioritized in the improvement works to be made for reducing the waiting time.

Özet

Bekleme hattı problemleri, bir işlemin gerçekleşmesi için bekleyen insan, makine ve malzeme topluluğuna bağlı olarak tanımlanır. Bekleme hattı ile ilgili problemlerin çözümünde sisteme ilişkin, geliş kaynağı, kuyruk süreci, servis kanalı ve servisten çıkış süreci gibi sistemle ilgili veriler kullanılmaktadır. İşletmeler probleminin yapısına göre bekleme hattı modeli oluşturulmakta ve kuyrukta hizmet için bekleme, hizmet süresi gibi hesaplamalar yapılmaktadır. Literatürde yer alan bekleme hattı modellerinde tüm kanallarının hizmet hızı eşit olarak kabul edildiği için, her bir hizmet kanalının toplam bekleme süresini ne ölçüde etkilediği belirlenememektedir. Bu çalışmada, bekleme hattında her bir hizmet kanalının toplam bekleme süresini ne kadar etkilediğinin belirlenmesini sağlayacak yeni bir yaklaşım sunulmuştur. Bu amaçla bekleme süresi sistem birimlerinin çok kriterli karar verme teknikleri ile ağırlıklandırılması yoluyla hesaplanmıştır. Çalışmada sunulan yeni yaklaşıma göre elde edilen sonuçlarla mevcut kuyruk kuramı yaklaşımı ile elde edilen sonuçlar karşılaştırılmıştır. Çalışmada elde edilen sonuçlar; hizmet kanallarının hizmet hızının farklılaştırılmasının daha gerçekçi sonuçlara ulaşılmasını ve hangi hizmet kanalının bekleme sürelerine daha fazla etki ettiğinin saptanmasını sağladığını ortaya koymuştur. Yeni metot ile elde edilen sonuçlara göre bekleme süresinin azaltılması için yapılacak iyileştirme çalışmalarında hangi hizmet kanallarına öncelik verilmesi gerektiğine yönelik öneriler sunulmuştur.
