in despite of all progress in technology in mining industry, still labor is one of the key factors in mining operation. this paper presents a system dynamics approach to evaluate the mining labor productivity. therefore, after the identification of main effective variables, two quantitative and qualitative models were built. the qualitative model illustrates the complex interrelated structure o...

Abstract The purpose of this article is to present a system dynamics (SD) model for studying the ‎interconnections among human being weight, eating habit, exercise, body fat, take-in medication, drugs-uses, and the health problems in general. Due to the fact that all of these factors have direct and indirect impacts on the expenses that insurance company have to pay this author is proposing a ...

This paper addresses ongoing research into visualization of system dynamics models to help the understanding of complex systems. The paper discusses a prototype under development named “The Two-Shower Model”. This collaborative interactive learning environment presents learners with a seemingly simple task: to reach a pleasant temperature in two showers that share the same hot water resource. T...

The purpose of this course is to help us harness the potential of system dynamics modeling as a tool for enhancing our understanding of interrelationships within complex systems. While system dynamics modeling has long been used as a tool to study and understand such systems, the emphasis in this course will be on its role in enhancing inter-disciplinary work related to understanding, and devel...

In this paper, a new virtual leader following consensus protocol is introduced to perform the internal and string stability analysis of longitudinal platoon of vehicles under generic network topology. In all previous studies on multi-agent systems with generic network topology, the control parameters are strictly dependent on eigenvalues of network matrices (adjacency or Laplacian). Since some ...

Designing effective technology-based learning environments is challenging. Designing effective technology-based learning environments to facilitate learning about complex knowledge domains is more challenging. To a large extent, the key to the puzzle lies in identifying which scaffolding strategies are more effective; and under which conditions. In a simulation-based inquiry-learning environmen...

Domestic households account for a significant portion of energy consumption and carbon emissions in the United Kingdom. Gains in energy and resource efficiency are undermined by the continuing rise in consumption. A multiutility service company (MUSCo) could enable households to make efficiency improvements through energy technologies and demand management, thus reducing overall consumption. We...
