The existing Ethernet and Token Ring based networks, known as legacy LANs, are no longer able to satisfy the constantly growing demand for more bandwidth and better quality of service. However, switching technology is a solution that seems to be able to cope with further expanding requirements. Introducing switches with new flow control schemes makes the networks faster and more efficient but, ...

Power demand varies on a daily and seasonal basis. Responding to changing demands over time is challenging for energy suppliers as it causes expensive power plants operate in high-demand seasons, usually summer, increasing the cost of electricity. Peak load shaving makes curve flatten by reducing peak shifting times lower demand, hence operation plants. Hence, there need large-scale long-term E...

Along with the rapid development of computer application technology in current society, information management is being applied to various industries. In this paper, through research on relational database, the author of this paper is going to create a modern efficient management system to change the catering enterprises’ old management model that consumes labor and material resource. Through d...

OPTIMIZING CONTROL OF OPERations in a municipal water-distribution system can reduce electricity costs and realize other economic benefits. However, optimal control requires an ability to precisely predict short-term water demand so that minimumcost pumping schedules can be prepared. One of the objectives of our project to develop an intelligent system for monitoring and controlling municipal w...

Materials flow analysis models have traditionally been used to track the production, use, and consumption of materials. Economic input-output modeling has been used for environmental systems analysis, with a primary benefit being the capability to estimate direct and indirect economic and environmental impacts across the entire supply chain of production in an economy. We combine these two type...

Rapid urban growth is resulting into increase in travel demand and private vehicle ownership in urban areas. In the present scenario the existing infrastructure has failed to match the demand that leads to traffic congestion, vehicular pollution and accidents. With traffic congestion augmentation on the road, delay of commuters has increased and reliability of road network has decreased. Four s...

In the paper, the performance of production networks by autonomous logistic processes and control versus those with conventional material planning under a dynamic business environment is investigated. Regarding this, by developing a discrete-event simulation model of an exemplary production network the competency of application of autonomous processes (in bearing flexibility) is presented. A ne...

Lambda Station is an ongoing project of Fermi National Accelerator Laboratory and the California Institute of Technology. The goal of this project is to design, develop and deploy network services for path selection, admission control and flow based forwarding of traffic among dataintensive Grid applications such as are used in High Energy Physics and other communities. Lambda Station deals wit...

inventory models play an important role in determining the optimal ordering and pricing policies. much work has been reported in literature regarding inventory models with finite or infinite replenishment. but in many practical situations the replenishment is governed by random factors like procurement, transportation, environmental condition, availability of raw material etc., hence, it is nee...
