“…It is briefly said that the genetic algorithm is a programming technique that uses genetic evolution as a problem-solving model. This is an evolutionary search algorithm to find an approximated optimal solution starting with a set of the initial solution [25][26][27][28]. The input of this program is a problem that needs to be solved and solutions are coded according to a template.…”

Capacitor optimal placement is one of the most important designs and control issues of power systems in order to reduce network losses, improve the voltage profile, reduce the reactive load, and reducing the power factor. The distribution network operator, taking into account two major goals of reducing real power losses and maximizing the return on investment required for installation of capacitive banks for sale to the transmission system, obtains the position, number, and capacity of capacitive banks. In this paper, the optimization problem is formulated for different values of the parameter "reactive energy value". After evaluating the objective function and implementing an optimization algorithm for each value of this parameter, the arrangement and capacitance of the capacitors in the network load nodes are obtained. Meanwhile, using the objective function defined in this paper, you can obtain the threshold for the sale of reactive energy, and by selling it to the transmission network, the investment in installing capacitor banks will be profitable for the distribution network operator.

“…Simulation models of the vessel traffic on the specific canal sections in function of the waterway capacity are developed according to the type of the technological process of vessel traffic on observed real section -two-way section ld=35000 m and one-way section lj=8030 m [17]. Simulation experiments are performed for various cases of vessel traffic densities, under constant basic parameters (vessel length L=77 m; navigation speed v=8 km/h; period duration t=30 days; vessels arrivals correspond to Poisson's distribution [10], FIFO/FCFS queue priority). For models with timesequential regulation of entrances, four cycle durations were used -30, 60, 120 and 240 minutes.…”

This paper analyses the management process of the vessel traffic control on one-way section on navigable canal with the adaptive time-sequential filter (traffic lights). One-way section on canal significantly decreases waterway capacity and requests special attention in control and regulation of the vessel traffic. The vessel traffic is a stochastic variable, and the vessel traffic control needs to be flexible and adaptive in order to achieve the required traffic flow with minimal delays. On the one-way section, two independent variable vessel flows from opposite directions are encountered, and fixed (predefined) signal plans lead to an increase in vessel delays. An appropriate solution is development of a Fuzzy Control System (FCS) for the vessel traffic control. A control algorithm is designed according to a set of linguistic rules that describes input parameters for the control strategy. The estimated and approximate input parameters are implemented in the algorithm as fuzzy sets. The final result of the developed algorithm is the traffic light scheme (duration of green light for certain direction). The presented control system can be used as an adaptive automatic control system for the vessel traffic control processes on navigable canals or on critical sections of other waterways.

“…The study compared the proposed schedule with the schedules formerly applied and presented notable similarities. Rahimikelarĳani et al (2018) considered the effects of closing the Houston Channel (to construct a bridge) for several alternative time slots. The study used statistical tools such as ANOVA and determined the best slot that minimised vessel waiting times.…”

The aim of this study is to develop a simulation model which is capable of mimicking actual vessel arrival patterns and vessel entrance decisions (which are made based on expert opinions generally) on congested, narrow waterways. The model is tested on the transit traffic pattern in the Strait of Istanbul. Based on a heuristic scheduling algorithm, this model decides entrance times and vessel types on the strait. The model, with different policies for day and night traffic, is run for a period of seven years with 20 replications for each year. The performance measures of the model are: average interarrival times, number of vessels passed and entrance times for each successive vessel pair in both traffic directions. The model results are congruent with the actual results of performance measures. Therefore, it may be deduced that the proposed algorithm can be a guide for operators regarding scheduling decisions in congested, narrow waterways.
