Starting Simulation in Excel

Steps for Starting Simulation in Excel 1. Generating randomness In simulation most important work is to generate random ness. You can use inbuilt rand()function for the same. When you enter the formula =RAND() in a cell, you get a number that is equally likely to assume any value between 0 and 1. Thus, around 25 percent of the time, you should get a number less than or equal to .25; around 10 percent of the time you should get a number that is at least .90, and so on 2. In order to conduct discrete simulation you need to use values of a discrete random variable. 3. Excel's VLOOKUP function stands for vertical lookup helps to find specific information in large data tables such as an inventory list of parts or a large membership contact list. Enter the data in the cells. Let the first column of data contains the part names (say B ) and the second column (column C) contains the price of each part. Vlookup can be used 1.Click on cell B1 and type the title lets say Pa...

While The World Braces For E-threats, India Moves Slow

By- Rajat Pandit, TNN After the first four "real" battlefields of land, air, sea and now increasingly space, India needs to get serious on the virtual front as well. The country should begin planning a full-fledged military cyber command, instead of the current piecemeal and disjointed steps to bolster cyber security, grappling as it already is with incessant online espionage and other attacks from China, Pakistan and others. This was the clear takeaway from the deliberations on cyber security and cyber warfare at the high-profile Munich security conference on Sunday, even though hardly figured in the discussions. experts said, the emergence of "cyber weapons" like the Stuxnet Software "Worm" that was used to sabotage Iran's nuclear program, had changed the entire security ball game, almost on a par with the use of nuclear bombs in 1945. "Someone used a cyber weapon in peacetime to physically destroy what the nation(Iran) could describe as ...

See and Learn
