This article describes how mobile operators occasionally fail to provide adequate service quality due to network overload, blackouts, or coverage white spots. Customers can increase the quality of connections by multihoming, i.e. using subscriptions of several operators. Multihoming is...

Article describes experiences in the teaching of a modelling and simulation course for students at Faculty of Organizational Sciences. The course consists of time-continuous simulation based on System Dynamics (SD) and discrete event simulation (DES). It is held in the 3rd year of studies, at...

In order to promote the development speed of the open innovation community, a dynamical system model of it is constructed, and the simulation is carried out to find out the rules of the running rules for the open innovation community. First, the basic characteristics of open innovation community...

This article conducts a theoretical analysis and empirical study on the complex relations among five elements (leadership, followership, leader-member exchange, leadership situation, and leadership performance) based on a two-stage least square method (TSLS). Results show that in China...

Food security (FS) challenges exist in both the developed and the developing countries, the difference being the severity and the proportion of the population affected. Previous studies maintain that chronic food insecurity at subsistence farming level has persisted due to a number of factors...

Although System Dynamics modelling is sometimes referred to as data-poor modelling, it often is –or could be– applied in a data-rich manner. However, more can be done in the era of ‘big data'. Big data refers here to situations with much more available data than was until recently...

Sub-Saharan Africa is home to 24.7 million people living with HIV of an estimated total of 35.0 million people globally in 2013. It also accounts for almost 70% of the new HIV infections globally. In West Africa, Cote d'Ivoire has the highest HIV prevalence, or 3.7% of the 2012 population, and...

While there is a general agreement that the use of public transportation should be encouraged, it has also been reported that the willingness and tendency to use the public transportation is dominated by the propensity of private car use. Consequently, the persistent increase in the modal share...

The process of privatization of the electricity market involves the serious needs of the industry in order to increase productivity, attract private investment and partnerships. If current trends continue, the total investment needed for the industry is not to be able to be supplied from...

System dynamics research has been introduced to some management fields including operations management, organizational behavior, project management, and market uncertainties research. This paper highlights the use of system dynamics in modeling work system design of projects' organizations...
