New city logistics approaches are needed to ensure efficient urban mobility for both people and goods. Usually, these are handled independently in dedicated networks. This paper considers conceptual and mathematical models in which people and parcels are handled in an integrated way by the same taxi network. From a city perspective, this system has a potential to alleviate urban congestion and ...

An investigation was conducted to assess the effect of incorporation of dried apple pomace (DAP) and corn bran (CB) as dietary fi bre sources on organoleptic, thiobarbituric acid reacting substance (TBARS) value and microbial quality characteristics of chevon rolls during refrigerated storage. DAP, CB and their combination (DAP+CB) were used at 6%, 3% and 2%+ 3% level respectively by replacing ...

PURPOSE Evaluation of doxorubicin stability over time when stored into the DC Bead embolic agent, in various containers, which are used for the delivery of the doxorubicin-loaded beads to the patients for up to 14 days under refrigerated conditions. METHODS The doxorubicin was loaded through the ionic exchange mechanism into the calibrated polyvinyl alcohol-based hydrogel beads (DC Bead), wit...

Electronic business and agents are among the most important and exciting areas of research and development in information and communication technology, with considerable potential impact and opportunities for the Maritime sector. This paper proposes the design of a Multi-Agent system for Internet Virtual Chartering Markets (MAVCM). The MAVCM system applies for business-to-business transactions ...

In this paper, we present a mathematical model to design the service network, that is the set of origin-destination connections. The resulting model considers both full and empty freight car movements, and takes into account handling costs. More specifically, the model suggests the services to provide, as well as the number of trains and the number and type of cars traveling on each connection....

The train timetabling problem considered is to find conflict free routes for a set of trains in a given railway network so that certain time window conditions are satisfied. We deal with the very large scale problem of constructing such timetables for the German railway network. A number of restrictions on different train types like freight trains or passenger trains have to be observed, e.g., ...

An analytical model is developed to assign regional freight across a multimodal highway and railway network using geographic information systems. As part of the regional planning process, the model is an iterative procedure that assigns multimodal freight traffic to the network to achieve overall network optimum. The procedure integrates optimization programming with traffic assignment, conside...

Intermodal freight transport has received an increased attention due to problems of road congestion, environmental concerns and traffic safety. A growing recognition of the strategic importance of speed and agility in the supply chain is forcing firms to reconsider traditional logistic services. As a consequence, research interest in intermodal freight transportation problems is growing. This p...

The paper discusses the issue of unproductivity during implementation operations in inland container terminals. authors hypothesize that two main factors influencing number unproductive manipulations are adopted operating strategy and occupancy level storage yard. presented model classifies operation time waiting for handling separately, also compares impact terminal selected strategies on time...

In this paper, we present the freight transportation planning component of the INWEST project. This system utilizes an evolutionary algorithm with intelligent search operations in order to achieve a high utilization of resources and a minimization of the distance travelled by freight carriers in real-world scenarios. We test our planner rigorously with real-world data and obtain substantial imp...
