Slide 58 Computer Modeling and Simulation

Slide 59 Calculated Risks: Computer Modeling and Simulation © 2008 Prentice-Hall, Inc. Computer modeling uses computers to create abstract models of objects, organisms, organizations, and processes. Examples of popular computer models:  Games (chess boards, sports arenas, and mythological societies)  Models of organisms, objects, and organizations  Flight simulators and simulations of science lab activities  Business, city, or nation management simulations

Slide 60 Calculated Risks: Computer Modeling and Simulation © 2008 Prentice-Hall, Inc. Computer Simulations: The Rewards Computer simulations are widely used. There are many reasons:  Safety  Economy  Projection  Visualization  Replication

Slide 61 Calculated Risks: Computer Modeling and Simulation © 2008 Prentice-Hall, Inc. Computer Simulations: The Risk GIGO Revisited  The accuracy of a simulation depends on how closely its mathematical model corresponds to the system being simulated.  Some models suffer from faulty assumptions.  Some models contain hidden assumptions that may not even be obvious to their creators.  Some models go astray simply because of clerical or human errors.  Still, garbage in, garbage out is a basic rule of simulation.

Slide 62 Calculated Risks: Computer Modeling and Simulation © 2008 Prentice-Hall, Inc. Making Reality Fit the Machine  Some simulations are so complex that researchers need to simplify models and streamline calculations to get them to run on the best hardware available.  Sometimes this simplification of reality is deliberate; more often it’s unconscious.  Either way, information can be lost, and the loss may compromise the integrity of the simulation and call the results into question.

Slide 63 Calculated Risks: Computer Modeling and Simulation © 2008 Prentice-Hall, Inc. The Illusion of Infallibility  A computer simulation, whether generated by a PC spreadsheet or churned out by a supercomputer, can be an invaluable decision- making aid.  The risk is that the people who make decisions with computers will turn over too much of their decision-making power to the computer.  Risks can be magnified because people take computers seriously. “ Trust your feelings.” Jedi Master in Star Wars

Slide 64 The Future

Slide 65 Inventing the Future: Truly Intelligent Agents © 2008 Prentice-Hall, Inc. Future user interfaces will be based on agents rather than on tools. Agents are software programs designed to be managed rather than manipulated. An intelligent software agent can:  Ask questions as well as respond to commands  Pay attention to its user’s work patterns  Serve as a guide and a coach  Take on its owner’s goals  Use reasoning to fabricate goals of its own

Slide 66 Inventing the Future: Truly Intelligent Agents © 2008 Prentice-Hall, Inc. Tomorrow’s agents will be better able to compete with human assistants. Future agents may possess a degree of sensitivity. A well-trained software agent in the future might accomplish these tasks:  Remind you that it’s time to get the tires rotated on your car and make an appointment for the rotation  Distribute notes to the other members of your study group or work group and tell you which members opened those notes

Slide 67 Inventing the Future: Truly Intelligent Agents © 2008 Prentice-Hall, Inc.  Keep you posted on new articles on subjects that interest you and know enough about those subjects to be selective without being rigid  Manage your appointments and keep track of your communications  Teach you new applications and answer reference questions  Defend your system and your home from viruses, intruders, and other security breaches  Help protect your privacy on and off the Net I don’t want to sit and move stuff around on my screen all day and look at figures and have it recognize my gestures and listen to my voice. I want to tell it what to do and then go away; I don’t want to babysit this computer. I want it to act for me, not with me. —Esther Dyson, computer industry analyst and publisher

Slide 68 Lesson Summary

Slide 69 Lesson Summary Even though the computer was designed to work with numbers, it can be an important tool for working with words as well. Word processing software enables you to use commands to edit text on screen, without having to retype messages. Outlining software, spell checkers, and online references can be very helpful. Desktop publishing produces professional-quality text-and-graphics documents. Spreadsheets can be used for tracking, calculating, forecasting, and almost any other task that involves repetitive numeric calculations. Most spreadsheet programs have charting capabilities. Presentation tools are essential to present your work to wider audience. Use your presentation tools effectively to provide good quality of presentation slides. © 2008 Prentice-Hall, Inc.

Slide 70 Lesson Summary (continued) Specialized software allows you to perform accounting tasks, tax preparation, and a variety of business functions without the aid of spreadsheets. Symbolic mathematic and statistical-analysis software can help present data in meaningful ways. Scientific visualization software can help us understand relationships that are invisible to the naked eye. Computer modeling and simulation can be powerful tools for understanding the world and making better decisions. © 2008 Prentice-Hall, Inc.
