Hello guys, currently i am doing my thesis about simulation by using flexsim. But i have several problem. i hope all of you can help me to solve this problem. oh ya, the result that i want to know is OUTPUT. 1. I am using USER EVENT to make the statistical report only from 3600 second to 36000 second, after that i want to know from 36000 second to 68400 second and so forth with the repeat event time is 32400 second. By using this USER EVENT: - from 3600 second to 36000 second, i got 1102 pcs - from 36000 second to 68400 second, i got 1101 pcs But If i am using the "conventional method" without using USER EVENT. I run the simulation from 0 second to 3600 second to know the result of output (for example: A), after that i continue run the simulation to 36000 second, then i know the result of total output from 0 second to 36000 second (for example: B), and then i can know the result of output from 3600 second to 36000 second by A-B, and so forth. By using this conventional method (WITHOUT USING USER EVENT): - from 0 -3600 second, i got 92 pcs - from 0 -36000 second, i got 1194, so from 3600 second to 36000 second, the output is 1102 pcs (1194 pcs-92 pcs) -> The result still same with using USER EVENT - from 0-68400 second, i got 2306 pcs, so from 36000 second to 68400 second, the output is 1112 pcs (2306 pcs-1194 pcs) -> NAHH! i got the different result, which by using user event, the total output from 36000 second to 68400 second is 1101 pcs, BUT by using conventional method, the total output from 36000 second to 68400 second is 1112 pcs. The question: 1. Which one is true? 2. Why the result of output can different? 3. Can i make the result of output by using USER EVENT same with the result of output by using CONVENTIONAL METHOD (WITHOUT USING USER EVENT)? Thankyou guys :)
