1. Abstract
System Dynamic Modelling is an approach to frame and solve complex problems. It is widely used for policy design and analysis. System dynamics analysis is a part of Systems Theory which is used to study the dynamic behaviour of complex systems. The theory is based on acknowledgement of the fact that the inter-relations between the various components of a model, time delays between processes are as important to analyse the behaviour of a model as is the analysis of individual components. SD models solve the problem of simultaneity (mutual causation) by updating all variables in small time increments with positive and negative feedbacks and time delays structuring the interactions and control.
In this paper, we have discussed the basic methodology of the technique, and the modelling process. Then, we have discussed the applications of SDM ranging from conventional ones like project management and science and engineering to exploring the concepts of SDM in Brand management and public health issues. 2. Historical background
This technique of solving problems was developed in 1950s by Prof Jay Forrester of Massachusetts Institute of Technology, during his involvement with General Electric. He developed his insights about the foundations of engineering which helped him in the creation of system dynamics. He studied the problem of instability in GE employment. In this he did hand simulations (or calculations) of the stock-flow-feedback structure of the GE plants, which included the existing corporate decision-making structure for hiring and layoffs. Forrester was able to show how the instability in GE employment was due to the internal structure of the firm and not to an external force such as the business cycle. These hand simulations were the beginning of the field of system dynamics.
During 1960s, the problem solving evolved from hand simulations…...

Nonlinear Modelling Application in Distillation Column Zalizawati Abdullah, Norashid Aziz, and Zainal Ahmad Abstract Distillation columns are widely used in chemical processes and exhibit nonlinear dynamic behavior. In order to gain optimum performance of the distillation column, an effective control strategy is needed. In recent years, model based control strategies such as internal model control (IMC) and model predictive control (MPC) have been revealed as better control systems compared to the conventional method. But one of the major challenges in developing this effective control strategy is to construct a model which is utilized to describe the process under consideration. The purpose of this paper is to provide a review of the models that have been implemented in continuous distillation columns. These models are categorized under three major groups:......

...CHAPTER 5 AN INTEGRATED SYSTEMS APPROACH TO CROP IMPROVEMENT G.L. HAMMER# AND D.R. JORDAN## # Agricultural Production Systems Research Unit (APSRU), School of Land and Food Sciences, The University of Queensland, Brisbane, QLD 4072, Australia. ## Hermitage Research Station, Queensland Department of Primary Industries, Warwick, QLD 4370, Australia. E-mail: g.hammer@uq.edu.au Abstract. Progress in crop improvement is limited by the ability to identify favourable combinations of genotypes (G) and management practices (M) given the resources available to search among possible combinations in the target population of environments (E). Crop improvement can be viewed as a search strategy on a complex G×M×E adaptation or fitness landscape. Here we consider design of an integrated systems approach to crop improvement that incorporates advanced technologies in molecular markers, statistics, bio-informatics, and crop physiology and modelling. We suggest that such an approach can enhance the efficiency of crop improvement relative to conventional phenotypic selection by changing the focus from the paradigm of identifying superior varieties to a focus on identifying superior combinations of genetic regions and management systems. A comprehensive information system to support decisions on identifying target combinations is the critical core of the approach. We discuss the role of ecophysiology and modelling in this integrated systems approach by reviewing (i) applications in......

Understanding How Big Data and Crowd Movements Will Shape the Cities of Tomorrow

...1 UNDERSTANDING HOW BIG DATA AND CROWD MOVEMENTS WILL SHAPE THE CITIES OF TOMORROW Andrew Leeson Pablo Alvarez Samya Ghosh AECOM UK 1. INTRODUCTION 1.1 A brief history of crowd modelling. From direct observations to simulation In 1895, the French social psychologist Gustave Le Bon wrote “The age we are about to enter, will truly be the Era of crowds” in his book “The Crowd: A Study of the Popular Mind” (Psychologie des Foules in French). If we take the 8am train to go to work, if we walk through a popular street on a Saturday, or if we go to a big event, we can see Le Bon’s words as a prophecy that describes the world in which we live. Pedestrian planning and crowd modelling have became more important in the last decades, mainly due to the increase in the number of big events that are organised and the accidents that sometimes happen during these events (Evers, 2011). Nowadays, architects, engineers, transport planners and event organisers make use of advanced software and mathematical models to predict the way in which pedestrians will move through train stations, streets, buildings, or stadia in order to create safe and efficient environments. In parallel to them, researchers and scientists are developing new algorithms and tools to improve the accuracy of the predictions. However, the first studies in this field were just based on direct observations, and they set the starting point for further research. According to Baer (1974), a good part......

Present study intends to investigate the same for Marala Hydropower Project (MHP) proposed on Upper Chenab Canal (UCC) off-shooting from Marala Barrage on River Chenab. In order to define the optimum crest level of the spillway such that there is no negative impact on the discharge passing capacity of the UCC head regulator, two-pronged strategy has been applied i.e. using computational flow dynamics (CFD) computer software and analytical approach. The results of modelling are first compared with the physical model of the said scheme for validation. This study will be helpful for any future hydropower development schemes on irrigation canals close to barrages. Key Words: Low Head Hydropower Development, Canal Regulation, Numerical Modelling, FLOW-3D 1. INTRODUCTION Water is diverted into a canal from a pool behind a barrage through a structure called the canal head regulator. This structure is also used as a regulation device for controlling the amount of water passing into the canal with the help of adjustable gates [1]. Spillway is one of the foremost important structures of a dam project. It enables the project to dispose off the excess water or negotiate floods in either controlled or uncontrolled manner in order to ensure the safety of the project. Spillway should be designed with......

Counterparts Credit Risk

...a swap with Bank XYZ as the counterparty, then exposure to them failing on that swap should be considered alongside exposure to them failing on their debt issues. Counterparty credit risk measurement Counterparty exposure is properly measured not just by the current value of trades with a counterparty, but also by how this value can move as markets move. Where sets of trades with counterparties feature multiple risk drivers/asset classes, modelling the potential exposure becomes a complex problem. Many investment banks have had to tackle this challenge. At UBS we have recently built a new counterparty risk trading system (see box, Modelling CVA and counterparty exposure), which we are rolling out internally and now making available to clients through UBS Delta, our portfolio risk management and performance system for clients. Table A shows exposure measures calculated for an example large portfolio of uncollateralised in-the-money (ITM) long-dated swaps – four sets of nettable trades (netting sets) with three counterparties. Exposure modelling Here we use a simple example to explain exposure measures: The only trade with counterparty “MadeUpBankLtd” is a foreign exchange forward, buying EUR10m for USD, one-year forward at 1.3600. We allow (for educational purposes only) currency returns to take seven equally spaced values, with defined probabilities, as in figure 1. We calibrate the distribution ensuring that the mean price equals the forward and standard deviation of returns......

Supply Chain Performance Measurement: a Literature Review

...measurement. Findings reveal that performance measurement in the new supply era is still an open area of research. Further need of research is identified regarding framework development, empirical cross-industry research and adoption of performance measurement systems for the requirements of the new era, to include the development of partnership, collaboration, agility, flexibility, information productivity and business excellence metrics. The contribution of this study lies in the taxonomy study, detailed description and treatment of methodologies followed and in shedding light on future research. Keywords: supply chain; performance measurement; metrics; maturity 1. Introduction Coordination of the supply chain (SC) has become strategically important as new forms of organisations, such as virtual enterprises, global manufacturing and logistics evolve. During the last few years, the focus has shifted from the factory level management of supply chains to enterprise level management of supply chains (Gunasekaran et al. 2005). Businesses becoming increasingly boundaryless (Puigjaner and Lainez 2008), increased challenges of globalisation, increased use of outsourcing, vendor managed inventory and advanced planning systems (APS), increased demands of integration led to a broadened supply chain definition (Meixell and Gargeya 2005). Differences between ‘traditional’ and ‘networked’ organisations are well discussed in Gunasekaran et al. (2005), emphasising......

System Modeling

...System Modeling Margaret Francies Strayer University Term Paper System Modeling Theory– CIS 331 Richard Guirguis Due on 12/8/2010 System Modeling Systems modeling or systems modelling is the approach to the study of the use of models to imagine and construct systems in business and IT development. In business and IT development the term "systems modeling" has multiple meaning. System Modeling can refer to analysis and design efforts, simulation and or system dynamics, and a study of the many uses of these models. There are different approaches to modeling: Agent based data and mathematical modeling. Quality management adopts a number of management principles that can be used by top management to guide their organizations towards improved performance. Principles such as: customer focus, leadership, people’s involvement, the process, system approach to management, continual improvement, facts, and a mutual benefit. . Decision making is a reasoning or emotional process which can be rational or irrational. The cognitive perspective is that the decision making process must be regarded as a continuous process integrated in the interaction with the environment. From a normative perspective, the analysis of individual decisions is concerned with the logic of decision making and rationality and the invariant choice it leads to it can be based on explicit assumptions or tacit assumptions. In decision making, objectives must be established and placed in the order......

What Is New Economy Geogragh

...Since 1990 a new genre of research, often described as the ‘new economic geography’, has emerged. It differs from traditional work in economic geography mainly in adopting a modelling strategy that exploits the same technical tricks that have played such a large role in the ‘new trade’ and ‘new growth’ theories; these modelling tricks, while they preclude any claims of generality, do allow the construction of models that—unlike most traditional spatial analysis—are fully general-equilibrium and clearly derive aggregate behaviour from individual maximization. The new work is highly suggestive, particularly in indicating how historical accident can shape economic geography, and how gradual changes in underlying parameters can produce discontinuous change in spatial structure. It also serves the important purpose of placing geographical analysis squarely in the economic mainstream. I. INTRODUCTION The study of spatial economics—of the location of production—has a long if somewhat thin history. Von Thünen’s (1826) analysis of land rent and use around an isolated city was roughly contemporaneous with Ricardo’s statement of comparative advantage; the location analysis of Weber (1909), the central-place theory of Christaller (1933) and Lösch (1940), the regional science of Isard (1956), and the urban systems theory of Henderson (1974) are all old and well-established ideas. None the less, the simple model developed in Krugman (1991) is widely regarded as having given birth to...

Agent-Based Social Simulation: Dealing with Complexity

...experimental methods with social phenomena, or at least with their computer representations; of directly studying the emergence of social institutions from individual interaction; and of using computer code as a way of formalising dynamic social theories. In this chapter, these advances in the application of computer simulation to the social sciences will be illustrated with a number of examples of recent work, showing how this new methodology is appropriate for analysing social phenomena that are inherently complex, and how it encourages experimentation and the study of emergence. Social simulation The construction of computer programs that simulate aspects of social behaviour can contribute to the understanding of social processes. Most social science research either develops or uses some kind of theory or model, for instance, a theory of cognition or a model of the class system. Generally, such theories are stated in textual form, although sometimes the theory is represented as an equation (for example, in structural equation modelling). A third way is to express theories as computer programs. Social processes can then be simulated in the computer. In some circumstances, it is even possible to carry out experiments on artificial social systems that would be quite impossible or unethical to perform on human populations. An advantage of using computer simulation is that it is necessary to think through one’s basic assumptions very clearly in order to......
