Problemde bir merkez depodan turlarınabaşlayan araçlar, müşterileri ziyaret edip tekrar depoya dönmektedirler. ARP’ninpek çok çeşidi bulunmaktadır. Akaryakıt dağıtımı da Kompartmanlı Araç RotalamaProblemi (KARP) adı verilen ARP’nin farklı bir versiyonunu sunmaktadır. KARP’dekarışmaması gereken akaryakıt ürünleri farklı kompartımanlarda taşınmaktadır.ARP’de olduğu gibi KARP için çözüm yöntemleri de genelde rota oluşturmasezgiselleri ve iyileştirme sezgiselleri olmak üzere iki kategoriyeayrılmaktadır. Her iki sezgisel kategorisi ile ilgili ARP ile ilgili geniş birliteratür olmasına rağmen, KARP için literatür sınırlıdır. Bu çalışmanın amacı Türkiye’de akaryakıtdağıtım problemi için bir başlangıç çözümü önermektir. Problemi KARP halinegetiren, her müşteriye birden fazla kez uğrama, kompartıman, tolerans gibideğişkenler bulunmaktadır. Tasarruf Algoritması (TA) bir yükleme algoritmasıile entegre edilerek problem için bir başlangıç çözümü önerilmiştir. Önerilen yöntem test problemleri üzerindetest edilmiş ve literatürle kıyaslandığında kabul edilebilir sonuçlarvermiştir. Önerilen yöntemle gerçek hayat akaryakıt dağıtım problemiçözülmüştür ve önemli maliyet iyileştirmesi gerçekleştirilmiştir. Önerilenyöntem hem KARP problemlerinde başlangıç çözümü olarak, hem de pratik uygulamaolarak Türkiye’de akaryakıt dağıtımında kullanılabilir. KW - lojistik KW - akaryakıt dağıtımı KW - araç rotalama problemi N2 - Oneof the well known problems in distribution is the Vehicle Routing Problem(VRP). In this problem, vehicles start their tours from a depot, they visit thecustomers and finish their tours in the depot again. There are several variantsof VRP. Fuel distributionprovides a different kind of VRP which is called as Multi Compartment VehicleRouting Problem (MCVRP). In MCRVP vehicles have compartments and incompatiblepetroleum products are delivered in different compartments of a vehicle. Forboth of the problems solution methods can be classified into two categories;route construction heuristics and improvemenet heuristics. While there is asignificant literature on VRP regarding these heuristics, the literature onMCVRP is much more limited. The aim of this study is to offer a constructionheuristics for a fuel distribution problem in Turkey. The problem has somefeatures such as compartments, visiting customers more than once and tolerancewhich turns it into a MCVRP problem. Savings Algorithm (SA) and a loadingalgorithm is integrated to develop a construction heuristics for the problem.Proposed heuristics is tested on test problems and acceptable results obtainedwhen compared with the literature. A real life fuel distribution problem issolved with the propsed heuristics and significant cost reduction has beenachieved. The proposed method can be used as a construction method in MCVRP andas a practical solution for real life problems in fuel distribution in Turkey. CR - Abdelaziz, F. B., Roucairol, C., & Bacha, C.
