Technology has been one of the most important factors of the economic and social growth and globally scaled competitiveness, although not respected as a separate factor by traditional economists until recently. It is now widely accepted that technology improvement plays a very major role on...

The organisation under discussion is a part of a Steel Company and consists of a group of captive underground coal mines required to produce coking coal, wash it in the coal washeries (benefitiation plants) and send the good quality clean coal to the steel plant for steel-making. The emergence...

The world can be complex and dangerous - the loss of state stability of countries is of increasing concern. Although every case is unique, there are important common processes. We have developed a system dynamics model of state stability based on an extensive review of the literature and...

In its Preface, The 9/11 Commission Report states: We learned that the institutions charted with protecting ... national security did not understand how grave this threat can be, and did not adjust their policies, plans, and practices to deter or defeat it (2004: xvi). Given current realities...

This paper develops a dynamic, behavioral model with an explicit spatial structure to explore the co-evolutionary dynamics between infrastructure supply and vehicle demand. Vehicles and fueling infrastructure are complementarities and their chicken-egg dynamics are fundamental to the emergence...

Research Resource: This project continues in its aims to create networks which reach a wide audience of researchers using qualitative data sources. The project is co-directed by Nigel Fielding, University of Surrey and Ray Lee, Royal Holloway,University of London; Ann Lewins is the project...

This paper explores the foundation of the financial accounting model. We examine the properties of the accounting equation as the principal algorithm for the design and the development of a System Dynamics model. Key to the perspective is the foundational requirement that resolves the temporal...

A system dynamics model is developed that explores the social dynamics of health-related actions to cope with fatigue. The process of self-regulation is simulated, particularly with respect to the consequences of non-linear feedback cycles. The rate of learning is identified as an intriguing...

Integration of electricity markets started to spread under the world-wide trend to economic liberalization. While some regions are managing better than others, lessons, both political and technical, highlight challenges ahead that need to be overcome.
