Trust in e-government is an important idea that should be critically investigated to help citizen favorably share information and make online transaction with government. This study aims to establish an e-government trust model from the behavioral perspectives of citizen. Based on the Technology Acceptance Model (TAM) and Customer Relationship Management(More)
Compared to traditional service, the characteristics of the customer behavior in electronic service are personalized demand, convenient consumed circumstance and perceptual consumer behavior. Therefore, customer behavior is an important factor to facilitate online electronic service. The purpose of this study is to explore the key success factors affecting(More)
A new insertion-based construction heuristic is presented to solve the multi-vehicle pickup and delivery problem with time windows. A non-standard measure, crossing length percentage, is presented in the insertion evaluation criteria to quantify the visual attractiveness of the solution. The heuristic is compared with a sequential and a parallel insertion(More)
Since the late 1990s, numerous governments have made huge investments in electronic government services. The rise of these services has led to a concurrent need to develop models of customer satisfaction of e-government services. This study aims to establish an e-government customer satisfaction measurement model from the behavioral perspectives of users.(More)
This study aims to exploring the key success factors affecting the service provided on the web portal of e-government. Based on the Theory of Planned Behavior(TPB) Technology Acceptance Model (TAM) and Selfservice Technology(SST), the study proposes an intergraded model for the empirical examination of the users' intention and behavior for using(More)
A dynamic vehicle routing and scheduling model that incorporates real time information using variable travel times is presented. Dynamic traffic simulation was used to update travel times. The model was applied to a test road network. Results indicated that the total cost decreased by implementing the dynamic vehicle routing and scheduling model with the(More)
When information on jobs is gradually known in the course of the system's operation, real-time techniques become increasingly important. The paper introduces a generic real-time truckload pickup and delivery problem, which includes the consideration of various costs associated with trucks' empty travel distances, jobs' delayed completion times, and job(More)
The paper introduces a generic real-time truckload fleet assignment and scheduling problem, which includes the consideration of various costs associated with trucks' empty travel distances, jobs' delayed completion times, and job rejections. A mixed integer programming formulation for the off-line version of the problem is proposed. Then three rolling(More)
