Mining companies can significantly cut costs by optimizing asset usage and knowing their future equipment needs.
In logistics, a realistic picture can be produced using simulation, including unpredictable data, such as shipment lead times. The Use of Simulation with an Example: Simulation Modeling for Efficient Customer Service This specific example may also be applicable to the more general problem of human and technical resource management, where companies naturally seek to lower the cost of underutilized resources, technical experts, or equipment, for example.
Firstly, for the bank, the level of service was defined as the average queue size. Relevant system measures were then selected to set the parameters of the simulation model - the number and frequency of customer arrivals, the time a teller takes to attend a customer, and the natural variations which can occur in all of these, in particular, lunch hour rushes and complex requests. A flowchart corresponding to the structure and processes of the department was then created. Simulation models only need to consider those factors which impact the problem being analyzed.
For example, the availability of office services for corporate accounts, or the credit department have no effect on those for individuals, because they are physically and functionally separate. Finally, after feeding the model data, the simulation could be run and its operation seen over time, allowing refinement and analysis of the results.
If the average queue size exceeded the specified limit, the number of available staff was increased and a new experiment was done. It is possible for this to happen automatically until an optimal solution is found. Still not clear on what simulation does or is? A simulation uses a mathematical description , or model, of a real system in the form of a computer program.
This model is composed of equations that duplicate the functional relationships within the real system. When the program is run, the resulting mathematical dynamics form an analog of the behavior of the real system, with the results presented in the form of data. Along with Ozik and their fellow researcher Nick Collier, Macal also worked on a modeling and simulation project that determined what might happen if the deadly Ebola virus which initially spread through West Africa in through , with devastating effects would impact that U.
Part of that process involved visiting Chicago hospitals to learn about Ebola-related procedures, then incorporating those procedures into their models a. Other Argonne scientists have used modeling and simulation to improve cancer treatment through predictive medicine — finding out how various patients and tumors respond to different drugs.
And those are just a couple of examples. Whether in academic science or industry, computer simulation is everywhere these days. Or systems that are unwieldy. And in Germany, a team at the Leibniz Supercomputing Centre performed earthquake simulations using the devastating Indian Ocean earthquake of , which spurred a massive tsunami, as their point of origin.
Sometimes we see relatively small tsunamis when earthquakes are large, or surprisingly large tsunamis connected with relatively small earthquakes. Simulation is one of the tools to get insight into these events. And that was just one of many issues highlighted. And this is where high-performance computing comes in. Which is to say, the simulations are much broader, and therefore even more realistic — at least from a hypothetical perspective.
What Is a Least Squares Model? What Is Web-based Simulation? Modeling and simulation of system design trade off is good preparation for design and engineering decisions in real world jobs. In this Web site we study computer systems modeling and simulation. We need a proper knowledge of both the techniques of simulation modeling and the simulated systems themselves.
The scenario described above is but one situation where computer simulation can be effectively used. Most if not all digital integrated circuits manufactured today are first extensively simulated before they are manufactured to identify and correct design errors. Simulation early in the design cycle is important because the cost to repair mistakes increases dramatically the later in the product life cycle that the error is detected.
Another important application of simulation is in developing "virtual environments" , e. Analogous to the holodeck in the popular science-fiction television program Star Trek, simulations generate dynamic environments with which users can interact "as if they were really there. Dynamic modeling in organizations is the collective ability to understand the implications of change over time. This skill lies at the heart of successful strategic decision process.
The availability of effective visual modeling and simulation enables the analyst and the decision-maker to boost their dynamic decision by rehearsing strategy to avoid hidden pitfalls. System Simulation is the mimicking of the operation of a real system, such as the day-to-day operation of a bank, or the value of a stock portfolio over a time period, or the running of an assembly line in a factory, or the staff assignment of a hospital or a security company, in a computer.
Instead of building extensive mathematical models by experts, the readily available simulation software has made it possible to model and analyze the operation of a real system by non-experts, who are managers but not programmers. A simulation is the execution of a model, represented by a computer program that gives information about the system being investigated.
