Aiming to large-scale Multiple-Depot Food transport Vehicle Routing Problem (MDFVRP), this study proposed an improved genetic algorithm solution frame based on the two-stage fuzzy clustering. In the static upper stage, the k-means technology is used to divide the MDFVRP into several one-to-many sub-problems. From the perspective of improving the customer satisfaction and integrating logistics r...
In our previous research, we compared the actual route recorded by a GPS device “PhotoTrackr” and the optimal vehicle route derived by using ArcGIS Network Analyst tool. VRP is the fundamental problem in the research fields of transportation, we focus on variations of CVRPTW (Capacitated VRP with Time Windows). Various types of VRP are studied to determine the optimal route under various constr...
This paper proposes an abstraction of emerging vehicle routing problems, the Vehicle Routing Problem with Black Box Feasibility. In this problem the routes of a basic VRP need to satisfy an unknown set of constraints. A black box function to test the feasibility of a route is provided. This function is considered of non-linear complexity (in the length of the route). Practical examples of such ...
Using newer vaccine platforms which have been effective against malaria in rodent models, we tested five immunization regimens against Plasmodium knowlesi in rhesus monkeys. All vaccines included the same four P. knowlesi antigens: the pre-erythrocytic antigens CSP, SSP2, and erythrocytic antigens AMA1, MSP1. We used four vaccine platforms for prime or boost vaccinations: plasmids (DNA), alphav...
This paper deals with the Pollution-Routing Problem (PRP), a Vehicle Routing Problem (VRP) with environmental considerations, recently introduced in the literature by [Bektaş and Laporte (2011), Transport. Res. B-Meth. 45 (8), 1232-1250]. The objective is to minimize operational and environmental costs while respecting capacity constraints and service time windows. Costs are based on driver wag...
During winter, aerial surveys are used to estimate densities of ducks that occupy open-water habitats. However, such surveys are ineffective for sampling forest-dwelling species, especially Aix sponsa (Wood Ducks), Anas platyrhynchos (Mallards), and Lophodytes cucullatus (Hooded Mergansers). We evaluated fi xed-radius plot (FRP) and Reynolds and Goodrum variable-radius plot (VRP) methods for es...
TIMOTHY P. MORAN: Characterization of Dendritic Cells Transduced with Venezuelan Equine Encephalitis Virus Replicon Particles as Therapeutic Cancer Vaccines (Under the direction of Jonathan S. Serody and Robert E. Johnston) Cancer vaccines seek to harness the specificity of T and B lymphocytes for reduction of tumor burden, as well as prevention of recurrent disease by establishing immunologica...
Vaccination represents the most effective control measure in the fight against infectious diseases. Local mucosal immune responses are critical for protection from, and resolution of, infection by numerous mucosal pathogens. Antigen processing across mucosal surfaces is the natural route by which mucosal immunity is generated, as peripheral antigen delivery typically fails to induce mucosal imm...
In this paper, we present the vehicle routing problem (VRP) with occasional drivers (OD) and order bundles (OB). The VRP-OD-OB is an extension of VRP-OD, where instead assigning one customer per driver, are assigned customers. To deal bundle-to-driver assignment, a bidding system exploited, in which company offers set raise their bids. These bids depend on features such as drivers’ destination,...
Many real-life applications of the vehicle routing problem (VRP) occur in scenarios subject to uncertainty or dynamic conditions. Thus, for instance, traveling times customers’ demands might be better modeled as random variables than deterministic values. Likewise, traffic conditions could evolve over time, synchronization issues should need considered, a real-time re-optimization plan can requ...
