Analytical techniques for measuring and planning railway capacity expansion activities have been considered in this article. A preliminary mathematical framework involving track duplication and section sub divisions is proposed for this task. In railways, these features have a great effect on network performance and for this reason they have been considered. Additional motivations have also ari...

This work proposes a method for the measurement of a country’s digital investigation capacity and saturation for the assessment of future capacity expansion. The focus is on external, or international, partners being a factor that could negatively affect the return on investment when attempting to expand investigation capacity nationally. This work concludes with the argument that when dealing ...

Abstract Capacity Expansion Models (CEMs) are optimization models used for long-term energy planning on national to continental scale. They typically computationally demanding, thus in need of simplification, where one such simplification is reduce the temporal representation. This paper investigates how using representative periods representation CEMs distorts results compared a benchmark mode...

Planning for capacity expansion forms a crucial part of the strategic level decision making in many applications. Consequently, quantitative models for economic capacity expansion planning have been the subject of intense research. However, much of the work in this area has been restricted to linear cost models and/or limited degree of uncertainty to make the problems analytically tractable. Th...
