this research uses a comprehensive method to solve a combinatorial problem of distribution network expansion planning (dnep) problem. the proposed multi-objective scheme aims to improve power system's accountability and system performance parameters, simultaneously, in the lowest possible costs. the dynamic programming approach is implemented in order to find the optimal sizing, siting and...

The efficiency of the public transport system in any city depends on integration of its major public transport modes. Suburban railway and public buses are the modes normally used by the majority of commuters in metropolitan cities of developed and developing countries. Integration of these two services reduces overall journey time of an individual. In this research, a model is developed for op...

Article history: Received 8.5.2012. Received in revised form 16.7.2012. Accepted 20.7.2012. In medium voltage optimal power distribution network routing, especially in the suburban and rural ones, it is often necessary to estimate additional construction costs of tie feeders enabling backup supply in comparison with a decrease in energy not supplied costs. This paper describes one fast approxim...

We develop a constraint programming based heuristic algorithm using column generation technique to solve a ship routing problem which the loading and unloading times of cargoes at pickup and drop-off locations are significant. In order to prevent congestions at the locations, we need to assign berthing time slots to each vessel to perform the loading and unloading tasks at different locations. ...

Distribution network expansion planning is a technique for managing the system effectively in face of future challenges. This work investigates design mesh distribution to allocate substations, DGs, voltage regulators, feeder routing, switch placement, and integration multiple energy carrier systems. Dynamic modeling multi-objective proposed this study identify optimal plan operational strategy...
