Algorithms for Pallet Building and Truck Loading in an Interdepot Transportation Problem
2016
This paper deals with the problem of a logistics company that has to serve its customers by first putting the products on pallets and then loading the pallets into trucks. Besides the standard geometric constraints of products not overlapping each other and not exceeding the dimensions of pallets and trucks, in this real problem, there are many other constraints, related to the total weight of the load, the maximum weight supported by each axle, and the distribution of the load inside the truck. Although the problem can be decomposed into two phases, pallet loading and truck loading, we have taken a combined approach, building and placing pallets at the same time. For each position in the t…
Considerations on oversized transportation in the UE(Community)
2017
The transportation problem is becoming increasingly complex at a national, European and global level. Achieving an efficient and safe transportation system with low environmental pollution, with a quick delivery is a requirement for any carrier in the 21 st century. When talking about oversized transport, the challenge is even greater. Making a low loader go through several European countries has proved to be more complicated than we expected, due to the lack of uniformity of laws in this field. This paper seeks to find these different regularities characteristics from one European country to another and to propose developing procedures leading to the design and implementation of cheaper an…
A new index for measuring seasonality: A transportation cost approach
2017
Abstract Seasonal fluctuations characterize many natural and social phenomena. Although the causes and impacts of seasonality are generally well documented in different study contexts, and many methods for isolating the seasonal component have been developed, considerably less attention has been paid to the measurement of the degree of seasonality. After reviewing the main indices used for measuring seasonality in different study contexts, we will propose a new approach in which seasonality is evaluated on the basis of the solution of a transportation problem. By considering the interdisciplinary nature of seasonal phenomena, the topic of measuring seasonality merits attention from a wide v…
