This article outlines methods to facilitate the assessment of the impact of electric vehicle charging on distribution networks at planning stage and applies them to a case study. As network planning is becoming a more complex task, an approach to automated network planning that yields the optimal reinforcement strategy is outlined. Different reinforcement measures are weighted against each other in terms of technical feasibility and costs by applying a genetic algorithm. Traditional reinforcements as well as novel solutions including voltage regulation are considered. To account for electric vehicle charging, a method to determine the uptake in equivalent load is presented. For this, measured data of households and statistical data of electric vehicles are combined in a stochastic analysis to determine the simultaneity factors of household load including electric vehicle charging. The developed methods are applied to an exemplary case study with Norwegian low-voltage networks. Different penetration rates of electric vehicles on a development path until 2040 are considered.

Nowadays, production companies are facing an increasingly volatile environment. Due to increasing globalization, but also de-globalization, taking into consideration an internal production network is becoming more and more important for companies, all in order to be able to counteract in an agile way the uncertainties such as swings in the demand. Current production network planning procedures focus on (re-)locating decisions without delving into what happens inside the plants, neglecting the dynamics of production networks, following a rigid top-down approach during the configuration phase, and they do not integrate the effects of planning tasks at the factory level (tactical and operational planning). In order to be able to make strategic decisions with a well-founded database regarding the production network, the effects on the tactical and operational level must be considered in an iterative way during the strategic decision-making process. The aim of this research is to define the requirements for an approach to strategic production network planning, which considers the effects at the tactical and operational level in an iterative way, and to develop a process model, derived from the requirements, that in its five phases considers the deficiencies of the existing approaches.

With the gradual implementation of the Belt & Road Initiative, China Railway Express (CRExpress) has gradually gained support as an important transportation mode between China and Europe. However, the high cost of operation, caused by the unscientific organization mode and the small quantity of returning cargo, hinders the further development of CRExpress. Prior studies have shown that applying the hub-and-spoke transportation organization mode to the CRExpress system could decrease operational cost effectively. To carry out network planning for CRExpress, based on its present situation and properties, a conventional hub location model is adjusted. The network planning location model for CRExpress which minimizes total operation cost and allows direct transportation mode is proposed as well as an algorithm based on the genetic algorithm (GA) approach. The reasonableness and feasibility of the model and algorithm are investigated and verified through a case study based on the CRExpress system. The result indicates that Chengdu, Yingkow, and Zhengzhou are selected as consolidation centers whereas Urumqi and Xining adopt direct transportation mode.
