“…Voltage dips reduction and transient voltage reductions between 10% and 90% of the nominal effective root-mean square value lasting between half cycle and one minute [9] are recognized as a key issue in distribution network with high DG penetration level, as can be seen in References [20,21]. However, there are specific circumstances in which an optimization algorithm needs to be adapted, such as a Long Distribution environment that includes manufacturing, distribution centers, terminals, geographic units, suppliers and end users [22]. Review paper of Djafar et al hits a very specific niche and it is important to emphasize it because it can be useful to those who are in a similar environment of complex power distribution systems, without being discouraged that perhaps such a case has not been processed in the scientific literature.…”

This paper aims to present carefully selected scientific papers that have pushed the boundaries in the application of advanced computational intelligence–based methods in power engineering, mainly in optimal power system management. Contemporary development of the Smart Grid and detailed framework for power grid digitalization enabled the real and efficient application of advanced optimization algorithms presented in this paper. Papers that are not directly related to Smart Grid management are also considered, since they solve the partial challenges of planning and development with metaheuristic procedures, and according to the authors, they are highly applicable and represent a fundamental starting point for wider application. This paper covers papers and research whose results are reproducible and can be realized in production-grade software. The emphasis of the paper is on the considerate and impartial way of providing a concise overview of the methods for solving technical challenges within the accepted Smart Grid architecture. The paper is the result of many years of research and commitment to this field and represents the foundation for present research and development.

“…Thus, long distribution channels have a lot of loops and connections between them. This is the reason why problems which are usual for distribution channels could be much more serious in long distribution channels (Djafar, Amer & Lee, 2013). On the other hand, short distribution channel assumes the direct distribution of products to the consumer or a small number of intermediaries, as well as links that need to be managed.…”

“…Concerning the above mentioned, the authors agree with Hyton (2005) that intermediaries in distribution channels represent a main source of problems. In this sense, long distribution channels are faced with the following problems (Djafar et al, 2013): variability, bottleneck, bullwhip effect, delivery time and distribution costs, and conflicts between intermediaries.…”

“…The bullwhip effect is a result of lack of coordination among partners, because of poor information sharing, inadequate market data, insufficient forecast techniques or other uncertainties (Djafar et al, 2013). Forecasting demand according to demand of previous partner, instead according to demand from point of sale is the major cause of bullwhip effect.…”

Distribution network is a system of activities that provide transfer of products between producers and final users. It is also known as distribution channel, marketing channel, distribution chain, distribution pipeline, market chain and trade chain. This network has two or more partners, so it has to be coordinated in the direction of order fulfilment and satisfied demand. As a partnership business network, distribution channels are very important, due to their role in responding to customers' requests. Distribution channels could provide competitive advantage for all partners along the network, through shorter delivery lead time and higher product availability. Although the main purpose of distribution channels is providing continuous flows of products to customers, they should be designed to fill customer's demand with minimum total cost. Determining the right number of facilities and proper locations for distribution network is an essential issue for companies involved in the channel. The issue of distribution channel's length has become more interesting due to the parallel existence of two different trends. On one hand, there is tendency for reducing number of partners, facilities or stages of distribution channels, with the purpose of avoiding extra expenses, but on the other hand there is a necessity to involve more partners in distribution channel, because that is a way for providing greater market share. Configuration of distribution channels depends on many factors. These factors have internal or external character. Therefore, the fact that the distribution of the same products in different countries can be performed completely differently is not surprising at all. In this regard, the aim of this papers is to classify the factors that affect the length of the distribution channel. In addition, the paper will also indicate advantages as well disadvantages of both long and short distribution channels. The goal of the analysis of the factors and the way of designing distribution channels, in terms of its length, is to make an adequate decision for increasing efficiency of the distribution network.
