The aim of this paper is to develop a model for estimating the urban logistics improvements potential based on success factors intermodal transport. There were two aspects considered building time efficiency model: achieving an improved transport capacity without purchasing new vehicles, and transferring responsibility poor shipment planning its owners by implementing factors. establish functio...

The purpose of this research and development project is to construct the foundations of a logistics IT centre with a universal and intermodal character, i.e., covering all modes of transportation and corresponding central functions related to warehouses and container terminals. Through its modular structure it is applicable to arbitrary concrete site dependent needs. It also contains intelligen...

This paper provides an overview of the container shipping supply chain (CSSC) by taking a logistics perspective, covering all major value-adding segments in CSSC including freight logistics, vessel port/terminal and inland transport logistics. The main planning problems research opportunities each segment are reviewed discussed to promote further research. Moreover, two most important challenge...

We examine the historical relation of logistics to strategy in the NZ dairy industry, with special emphasis on OR/MS applications. We review the various ways in which efficiency has been realized in logistics in the industry (mostly through recourse to OR/MS). We especially dwell on how the structure (e.g., operating mechanisms) of the NZ dairy industry has supported and/or hindered the focus o...

The rapidly developing, worldwide marketplace is leading to the geographical dispersion of production, assembly and distribution operations. This paper deals with three aspects of international logistics networks: strategic, tactical and operational. The strategic level designs the logistics network, including prescribing facility locations, production technologies and plant capacities. The tac...

Operational Research (OR) techniques have been applied, from the early stages of the discipline, to a wide variety of issues in education. At the government level, these include questions of what resources should be allocated to education as a whole and how these should be divided amongst the individual sectors of education and the institutions within the sectors. Another pertinent issue concer...

This paper develops an economic assessment of a multimodal transport network for single pallets. A shipment-size choice model is estimated to calculate the shippers’ reactions and their economic benefits from that transport network. In the model, the major factor influencing logistics decisions—the balance between warehouse and storage cost—is explicitly taken into account. The functional form ...

Capacity uncertainty is a common issue in the transportation planning field. However, few studies discuss the intermodal routing problem with service capacity uncertainty. Based on our previous study on the intermodal routing under deterministic capacity consideration, we systematically explore how service capacity uncertainty influences the intermodal routing decision. First of all, we adopt t...

In the aftermath of a hurricane, humanitarian logistics plays critical role in delivering relief items to affected areas timely fashion. This paper proposes novel stochastic look-ahead framework that implements two-stage programming model rolling horizon approach address evolving uncertain system state during post-hurricane operations. The executes this is formulated as mixed-integer problem. a...
