A Decision Support System and its Application for International Sea-Rail Multimodal Freight Transportation Operations

Öz

Multimodal transportation generally refers to international freight transport using a combination of at least two different transport modes rather than a single such as trucks used in road transportation. Multimodal transportation has been studied in the literature to develop more effective and efficient methods to carry freight; yet, pricing policy has not been examined thoroughly. The fixed price is the main policy adopted in freight transport sector in Turkey. However, revenues at the operational level may be increased by applying dynamic pricing approaches, which have been commonly used in the airline and hospitality sectors. In this study, a revenue-driven web-based decision support system is developed for international sea-rail multimodal freight transport operations. A web-based prototype is designed that involves the user interface, logic interface and database to present the operational planning outputs of the project entitled Ship2Rail. The underlying ER model is described and the working principles of the data model used in the database design is explained. Furthermore, the elements of fixed and dynamic pricing policies depending on the demand behavior and time constraint are discussed.

ULUSLARARASI DENİZ-DEMİR YOLU KOMBİNE YÜK TAŞIMACILIĞI OPERASYONLARI İÇİN BİR KARAR DESTEK SİSTEMİ VE UYGULAMASI

Öz

Kombine taşımacılık, uluslararası yük taşıma zincirinde genellikle tek tip taşıma türü olan kara yolu yerine, en az iki farklı taşıma türünün birleştirilmesi ile yapılan taşımacılığı ifade etmektedir. Literatürde kombine taşımacılık ile yüklerin nasıl daha etkili ve verimli taşınacağı araştırılmış olmakla beraber fiyatlandırma politikası ayrıntılı incelenmemiştir. Günümüzde kombine taşımacılıkta genellikle sabit fiyat politikası uygulanmaktadır. Ancak, hava yolu taşımacılığı ve otel yönetimi gibi sektörlerde görülen dinamik fiyatlandırma yaklaşımlarının kombine taşımacılık operasyonel planlamasında uygulanmasıyla geliri artırmak mümkün olabilmektedir. Bu çalışmada, gelir yönetimine göre uluslararası deniz-demir yolu kombine yük taşımacılığı senkronize operasyonları için web tabanlı bir karar destek sistemi sunulmuştur. Ship2Rail adlı projenin operasyonel planlama çıktılarını sunmak amaçlı hazırlanan bu web tabanlı platformu oluşturan kullanıcı arayüzü, mantık arayüzü ve veri tabanlarını içeren bir prototip tasarımı betimlenmiştir. Buna temel teşkil eden varlık-ilişki modeli sunulmuş, veri tabanı tasarımı için kullanılan veri modelinin çalışma prensipleri açıklanmıştır. Ayrıca, talebe göre sabit ve dinamik fiyatlandırma politikalarını içeren senaryolarda gözetilen, farklılaşan unsurlar vurgulanmıştır.
