A model space and space compression theory is developed. The theory defined an N-1 security network as a model, and then defined a model space according a given model. Using this theory in Particle Swarm Optimization can prevent particles form searching in fund areas and improve their search efficiency. Put forth a model structure mutation method, which can make particles jump out of local opti...

In the current era of cellular world, cell planning plays an important role to achieve better performance of the cellular network. Capacity expansion and cost optimization of a newly activated base station by placing it at an optimized location is one of the primary objectives of the current manuscript. The locations of the new as well as the existing base stations are directly correlated to th...

The network expansion problem is a very important practical optimization when there need to increment the flow through an existing of transportation, electricity, water, gas, etc. In this problem, augmentation can be achieved either by increasing capacities on arcs, or adding new arcs network. Both operations are coming with cost. paper, finding minimum cost so that modified transport given amo...

Abstract The urban 35kV substation is the link between main network and distribution network, economic power supply site selection optimization are keys to coordinated planning of network. A comprehensive evaluation system established for collaborative from three aspects: social benefit, construction economy, operation combination scale expansion method rough set applied determine combined weig...

Abstract With the implementation of China’s “carbon neutral, carbon peak” dual target action plan and construction a new power system, access to high proportion energy microgrid has changed function form distribution network. The current capacity network absorb cannot fully meet needs future development. Through rational planning, carrying for can be improved, operation efficiency expansion inv...

urban expansion model (uem) was adapted to simulate urbanization which implements geospatial information systems (gis), artificial neural networks (anns) and remote sensing (rs). two satellite imageries with specific time interval, socio-economic and environmental variables have been employed in order to simulate urban expansion. socio-economic and environmental variables were used as inputs wh...

The complexity and uncertainty of power sources connected to transmission networks need be considered. Planners information on the sustainability economics network expansion planning (TNEP). This work presents a newly proposed method for TNEP that considers high-penetration solar energy by using particle swarm optimization (PSO) algorithm. sources, thermal hydropower plants, conditions load wer...

banks are one of the financial firms that different decisions are always minor system. an example of automation systems for human resources, finance, internal controls and so named. that is why banks are looking for a comprehensive system to integrate its activities are concentrated. so the enterprise resource planning system (erp) is one of the important applications of information technology ...
