In this study, a decision support system prototype is developed to solve the demand-based vehicle assignment problem within the scope of autonomous-shared vehicle management systems. First, a database suitable for the demand structure is designed for the developed decision support system prototype. Then, a user-friendly, web-based interface is designed so that customer requests can be stored and viewed by the system administrator in an integrated system design. An example case study is used to illustrate the system implementation where the city center of Bursa with its high urban traffic density is considered. In the case study, three parking stations are assumed to be located in three different central districts (namely Yıldırım, Osmangazi and Nilüfer) through the east-west direction of the city in order to meet customer demands. A multi-commodity network flow problem-based model is used to solve the vehicle assignment problem. It is thought that it will be beneficial in terms of the efficiency of the rapidly growing enterprises of shared-vehicle services to optimize their vehicle relocations and other operations using decision support systems similar to the one developed in this study.

Otonom-Paylaşımlı Araç Yönetim Sistemi

Öz

Bu çalışmada, otonom-paylaşımlı araç yönetim sistemleri kapsamında, talep tabanlı araç atama problemi çözümü için bir karar destek sistemi prototipi geliştirilmiştir. Öncelikle, geliştirilen karar destek sistemi prototipi için talep yapısına uygun bir veritabanı tasarlanmıştır. Ardından, bütünleşik bir sistem yapısı içerisinde, müşteri taleplerinin kaydedilebilmesi ve sistem yöneticisi tarafından görüntülenebilmesi için kullanıcı dostu web tabanlı bir arayüz tasarlanmıştır. Geliştirilen sistemin çalışması bir örnek uygulama üzerinde gösterilmesi amacıyla kent trafik yoğunluğu yüksek olan şehirlerden Bursa şehir merkezi ele alınmıştır. Oluşturulan uygulama kapsamında, müşteri taleplerini karşılamak üzere şehrin doğu-batı ekseni doğrultusundaki üç merkez ilçesinde (Yıldırım, Osmangazi ve Nilüfer) olmak üzere üç farklı konumda park istasyonu belirlenmiştir. Araç atama probleminin çözümü için çok-ürünlü ağ akış problemi bazlı bir model kullanılmıştır. Günümüzde paylaşımlı araç hizmetleri için hızla artmakta olan girişimlerin, araç konumlandırmalarını ve diğer operasyonlarını bu çalışmada kurgulanana benzer karar destek sistemleri kullanarak optimize etmelerinin verimlilik açısından faydalı olacağı düşünülmektedir.
