transfer-transport of the waste is one of key functional elements in solid waste management from technical and financial viewpoint. unfortunately very few reach activities has been conducted in this field regarding local characteristic of phenomenon which urges undertaking local surveys and research projects. tehran organization of waste recycling and composting has decided to investigate diffe...

for any agency dealing with the design of the water distribution network, an economic design will be an objective. in this research, central force optimization (cfo) and differential evolution (de) algorithm were used to optimize ismail abad water distribution network. optimization of the network has been evaluated by developing an optimization model based on cfo and de algorithm in matlab and ...

We present a heuristic algorithm for the optimization of transport on complex networks. Previously proposed network transport optimization algorithms aim at avoiding or reducing link overload. Our algorithm balances traffic on a network by minimizing the maximum node betweenness with as little path lengthening as possible, thus being useful in cases when networks are jamming due to node congest...

In this paper, we do a performance analysis of the cooperative HARQ protocol in a wireless adhoc multihop network employing spatial ALOHA. We model the nodes in such a network by a homogeneous 2-D Poisson point process. We study the tradeoff between the transport capacity submetrics inherent in the network by optimizing the transport capacity w.r.t the network design parameters, HARQ coding rat...

This paper presents a freight transport optimization model that simultaneously incorporates multimodal infrastructure, hub-based service network structures, and the various design objectives of multiple actors. The model has been calibrated and validated using real-life data from the case study of hinterland container transport of the Netherlands, where CO2 pricing, terminal network configurati...

The transportation is gradually integrated into the circulation system of bulk goods, and developing growing. Transportation has advantages high efficiency, quality green environment, In time, efficiency cost than traditional transport certain advantages. This paper analyzes logistics network, which mainly includes in transit, transit cost, time cargo special cost. discusses detail carbon consu...

the exponential growth of the flow of goods and passengers, fragility of certain products and the need for the optimization of transport costs impose on carriers to use more and more multimodal transport. in addition, the need for intermodal transport policy has been strongly driven by environmental concerns and to benefit from the combination of different modes of transport to cope with the in...
