Citation: Suaria G, Aliani S, Merlino S and Abbate M (2018) The Occurrence of Paraffin and Other Petroleum Waxes in the Marine Environment: A Review of the Current Legislative Framework and Shipping Operational Practices. Front. Mar. Sci. 5:94. doi: 10.3389/fmars.2018.00094 The Occurrence of Paraffin and Other Petroleum Waxes in the Marine Environment: A Review of the Current Legislative Framew...
A classification scheme for routing and scheduling problems in liner shipping is developed and subsequently used to classify existing literature on the subject. Based on the classification the articles are grouped, and the main characteristics of each group and article are described. The grouping may serve as a catalyst towards developing a model or a group of models that covers the main proble...
It is not enough to seek solutions to these problems from the standpoint of an individual technical or industrial group, or even that of a nation; the whole subject needs a detailed review at the widest international level. Shipping itself is essentially an international operation and the hazards that it may entail are seldom of a purely national or even regional character. This is particularly...

Marine biological invasions have increased with the development of global trading, causing the homogenization of communities and the decline of biodiversity. A main vector is ballast water exchange from shipping. This study evaluates the use of ecological niche modelling (ENM) to predict the spread of 18 non-indigenous species (NIS) along shipping routes and their potential habitat suitability ...
This paper considers a dynamic lot size problem faced by a producer who supplies a single product to multiple customers. Characterized by their backorder costs as well as shipping costs, the customer with a high backorder cost is the one whose need for the product is more critical than the need of a customer with a low backorder cost. We show that the general problem with time-varying, customer...
Globalization is motivated by the potential for cost reduction through access to lower labor costs, as well as by the potential for increased sales through access to new markets. A review of cost data indicates the potential savings related to labor as compared to the potential additional costs related to raw materials, shipping, and tariffs. A logistics cost model is then presented that consid...
Recent studies reveal that publicly available SPARQL endpoints exhibit significant limitations in supporting real-world applications. In order for this querying infrastructure to reach its full potential, more flexible client-server architectures capable of deciding appropriate shipping plans are needed. Shipping plans indicate how the execution of query operators is distributed between the cli...
This study develops a Zero-Inflated Negative Binomial (ZINB) regression model to evaluate the factors influencing the loss of human life in shipping accidents using ten years’ ship accident data in the South China Sea. The ZINB regression model results show that the expected loss of human life is higher for collision, fire/explosion, contact, grounding, hull damage, machinery damage/failure and...
We present a matheuristic, an integer programming based heuristic, for the Liner Shipping Network Design Problem. The heuristic applies a greedy construction heuristic based on an interpretation of the liner shipping network design problem as a multiple quadratic knapsack problem. The construction heuristic is combined with an improvement heuristic with a neighborhood defined by the solution sp...
