This paper aims to introduce a method for better designing of Distribution Center operation process so as to increase the operation efficiency at lower cost. Considering the current situation of a given Distribution Center, this paper designs the operation process and provides the layout chart based on a given number of equipment, operators and volume of goods, etc. Then the concrete actions in...

In this research, we apply a discrete event simulation approach to explore how enterprises in the Chinese mainland make a successful operation with the aid of e-commerce. This paper examines the effects of proposed four kinds of transshipment operation network structures on the performance under different policies of transshipment and inventory allocation. Results show that: 1) transshipment ba...

Rate-Function Scheduling (RFS) is a new deadline-based packet-scheduling service discipline that supports qualityof service guarantees for applications with real-time communication requirements. RFS is distinguished from other service disciplines in that it achieves all of the following goals: analytically-derived perjormance bounds, perjormance isolation among sessions, jlexible and eficient a...

IMPORTANCE A pressing question in military suicide prevention research is whether deployment in support of Operation Enduring Freedom or Operation Iraqi Freedom relates to suicide risk. Prior smaller studies report differing results and often have not included suicides that occurred after separation from military service. OBJECTIVE To examine the association between deployment and suicide amo...

A terminology service makes diverse terminologies/ontologies accessible under a uniform interface. The EUTRANSFoRm project built an online terminology service for European primary care research. The service experienced performance limitations during its operation. Based on community feedback, we evaluated alternative solutions and developed a new version of the service. Based on BioPortal's sca...

The provision of end-to-end Quality of Service (QoS) for multimedia services over IP-based networks is already an open issue. To achieve this goal, service providers need to manage Service Level Agreements (SLAs), which specify parameters of the services operation such as availability and performance. Additional mechanisms are needed to quantitatively evaluate the user-level SLA parameters. Thi...

in this paper, we propose a sensitivity analysis for evaluating the effectiveness of recovery solutions in the case of disturbed rail operations. indeed, when failures or breakdowns occur during daily service, new strategies have to be implemented so as to react appropriately and re-establish ordinary conditions as rapidly as possible. in this context, the use of rail simulation is vital: for e...

72 Published by the IEEE Computer Society 1089-7801/09/$25.00 © 2009 IEEE IEEE INTERNET COMPUTING S oftware systems built on top of serviceoriented architectures (SOAs)1 use a triangle of three operations — publish, !nd, and bind — to decouple roles participating in the system. Publish and !nd put requirements on the service registry and the interface de!nition language. To publish services, an...
