restructuring the recent developments in the power system and problems arising from construction as well as the maintenance of large power plants lead to increase in using the distributed generation (dg) resources. dg units due to its specifications, technology and location network connectivity can improve system and load point reliability indices. in this paper, the allocation and sizing of di...

The advent of the fourth Industrial Revolution (Industry 4.0) requires wireless networked solutions to connect machines. However, industrial environment is notorious for being averse communication, with traditional resource mechanisms prone errors because metallic objects. In this work, we propose exploit knowledge location derive context information and dynamically allocate resources in <itali...

Surveying programs of study at institutions higher learning throughout the world reveals that one natural disciplinary coupling is statistics and operations research, although these two specific disciplines currently lack an active synergistic research interface. Similarly, development spatial optimization has occurred in parallel nearly isolation. This paper seeks to alter this situation by in...

Hub location problems, with the hub-and-spoke network structure, involve locating hub facilities, allocating the non-hubs (spokes) to the hubs, and determining the path for each origin-destination pair. In a pure hub-and-spoke network, all hubs, which act as intermediate switching or transshipment points for internodal flows, are fully interconnected and none of the non-hubs are directly connec...

Distribution network design as a strategic decision has long-term effect on tactical and operational supply chain management. In this research, the location-allocation problem is studied under demand uncertainty. The purposes of this study were to specify the optimal number and location of distribution centers and to determine the allocation of customer demands to distribution centers. The m...

The existing works considering the flow-based discount factor in the hub and spoke problems, assume that increasing the amount of flow passing through each edge of network continuously decreases the unit flow transportation cost. Although a higher volume of flow allows for using wider links and consequently cheaper transportation, but the unit of flow enjoys more discounts, quite like replacing...

this paper offers an approach that could be useful for diverse types of layout problems or even area allocation problems. by this approach there is no need to large number of discrete variables and only by few continues variables large-scale layout problems could be solved in polynomial time. this is resulted from dividing area into discrete and continuous dimensions. also defining decision var...

The appropriate planning of infrastructure protects people’s lives and property. Fire stations are an essential part a city’s they must be precisely located to shorten emergency response times reduce casualties. Recently, the focus city service has shifted from fire suppression technical rescues. We compared spatial distribution rescues at scale show variation in their influences. An integrated...
