Abstract The paper aims to examine the development of competitive advantage in Facebook for brand awareness. The paper describes a dynamic model of the simulation system associated with the stock of online communication and customer engagement, the increase of users and the geographic connection that social media provide.

The purpose of this paper is to examine the impact of knowledge [ creation mode (e.g. goal-driven and goal-free) and organizational culture on knowledge creation and sharing performance in the context of high technology (high-tech) companies [ with the contribution of Dynamic Simulation Model. Both goal-free and goal-framed creation modes are more likely to support knowledge creation, while the goal-driven mode is not likely to be favorable for knowledge creation. The paper has leveraged the systems dynamic paradigm to conduct sustainable enterprise modelling and iThink system to implement the models. High-tech companies who are frequently looking for new ideas for product design [ and manufacturing technologies [ are more likely to adopt the goal-free creation mode. High-tech companies who would like to emphasize goal achievement with respect to creation in manufacturing should form an organizational culture with a characteristic of market competition [. Also, a company with both goal-free and/or goal-framed creation modes is more likely to be willing to frame its strategic decisions (or goals) and then freely look for creative ways to reach the goals.

The paper seeks to propose the concept of sustainable enterprise simulation models. The social, environmental and economic models are developed and simulated using iThink in the context of a high technology (high-tech) company. With the rapid growth of Social Networks [, Open source applications are increasingly invading the world of Web. High-tech companies must adapt to the world of open source, by the people who work in them, until their products. The paper has leveraged the systems dynamic paradigm to conduct sustainable enterprise modelling and iThink system to implement the models. It uses the design science research methodology for the proof of concept of the models and modelling processes. The models have been developed for a high-tech company and tested in the business settings. These models were finalised through a number of revisions and iterations of the design, develop, simulate, test and evaluate. While leaders have been around for thousands of years, we have attempted to show how the old rules of leadership [ are no longer helpful in dealing with the new games of the 21st century. In the high-tech companies we studied, we discovered patterns of leadership practice that not only yielded remarkable results, but also created a deep sense of meaning and identity for those involved.

Today’s world is characterized with rapid engineering and technological increase where enterprises search to develop competitive vantage based on the extensive use of information and communication technology, a crucial succeeder in today’s competitive market. Information and communication technology, a factor characterized as a foundation and complementary to innovation, affects business exploitation, exploration and market competitive presence in several ways. This paper aims at explaining how the Information and Communication Technology trajectory and its adoption affects the export intensity of business sphere along with other important variable factors using a large data sample of 3500 business firms using hybrid simulation with Anylogic 7.2 University and eventually analyzing empirically this relation through an economic based regression analysis model using E-Views 8. The explanatory variables include many factors extensively analyzed. The analysis is based on the epidemic model of information and communication technology in business sphere. The reason this paper was created is to provide the ultimate combination compounding of crucial factors that affect the information and communication technology adoption of businesses that seek to adopt new technological ways to expand their export performance and intensity. Thorough research through the paper resulted in a robust pattern across the adoption variables used that lead to the successful adoption of the information and communication technology key factor in businesses as regarding their export activity and their export intensity.

This paper suggests the management of company resources in order to establish a successful project team. The proposal is being reported after modeling the essential soft skills of a project team, interacting with the negative factors and providing the benefits to the team. Hence, is mentioned what a project manager must do as leader of an effective project and which parameters should follow for establishing it. Last but not least, a one year simulation is represented—the best scenario—after many case studies. The model and the simulation developed in iThink platform.

The last years have seen a rapid increase both of the number of users on social media and particularly on Facebook and also, on the number of different types of applications available for use (Kluemper et al., Research in personnel and human resources management, Emerald Group Publishing Limited, Bingley, 2016). This paper attempts to model and simulate the promotion of new IT products processes. The study of the results obtained through simulation dynamic model, which was developed in order to test the potential profitability of a business.

Mobile commerce (m-commerce) is a rapidly growing industry, which derives from e-commerce, and within the next few years is expected to conquer a great part of the global market share. There are several factors that can play a major role in the success of an m-commerce website. The ones that should be taken most into account can be distinguished in three categories. The first one is Security and Trust, which concerns safe transactions online and giving the user a sense of trust and no second thoughts when buying a product through his/her smartphone. Second, Personalization–Localization, which is about adjusting properly the content depending on the user’s preferences and local needs, trends, and conditions. Last but not least, user’s convenience, which can be described in three sub-categories: Speed, Accessibility, and Mobile Friendly Design. All of the above contribute in a pleasant online experience for the user. This research takes the investigation of the most crucial factors one step further, examining them from a different perspective, through the innovative way of a dynamic simulation model. After the appropriate data were given to the model in order to make it sufficient to run and return valuable information, the simulation was executed for the desired time (in this research a year), the results were collected and the conclusion that came up was that security-trust is the most crucial factor in the success of m-commerce, whose absence could result in the minimization of it as far as sales are concerned.

Internet provides a lot of tools and technologies designed to help people collaborate and communicate with each other. Collaboration tools are a category of tools such as chat, application sharing, videoconferencing and e-mail (Dobre, Seria Matematică - Informatică – Fizică LVIII:51–56, 2006). In additition, online collaboration tools are based on webpages, clients and servers, so all the aspects of a competitive webpage should be considered in order to make a good collaboration tool. Modelling is the process of representing a physical system, or natural phenomenon, or even an idea. In this paper we will simulate the process of developing a web-based collaboration tool, in order to find how the available resources should be properly distributed.

In this research, paper will be highlighted the dominant role that the video games hold nowadays. It is undeniable that as time and technology go by, more and more people spend time playing games on their smartphones. As shown by recent studies, 44% of the game developers are working on a game that will be released on smartphone or tablet (Game Developers Conference 2016). This has led, in turn, to a growing number of companies taking interest in releasing video games for smartphones, increasing the competition. Due to the above, companies have realized the significance of importing more and more innovative ideas in their video games so they get more appealing to buyers, resulting in holding a bigger share in video games market. The impact of these innovations in a company’s function and the profit, or loss, they can cause will also be investigated. This will be examined via the modeling and simulation procedure of the innovations’ developing process, which is proven to be the safest and quickest way to try different environmental factors, observe how they influence the model and compare different outcomes.
