    Why can't everyone use real life examples like you did. I've been trying to make sense of the whole theory for the last couple hours and now everything makes sense . Thank you very much

      Thank you very much! I try to simplify these notions in order to make sense for everyday encounter. I totally understand the frustration that most online tutorials are really in-depth and difficult. Thanks for watching the video.

    I am glad I found this theory.
    I had investigated this topic on my own and discovered most of this theory on my own without knowing about it.
    Now I know of this theory, I can formally study it to improve my productivity further!

    Thanks for the video, however there is an error in your video. If Lambda (the arrival rate - 10 car per hour) is higher than mu (the service rate - 6 cars per hour) the queue will explode. i.e. the waiting time will be infinite. Could it be that you mixed up the values of lambda and mu?

    Can I get a solution to this: Demand is: 2,250 vehicles/hr; average speed of 60 mph; capacity of the
    lane closure is 25 mph; we have 2 lanes of evenly distributed traffic.
    What can we report to be the expected speed of the shock wave traveling
    backwards?

    May I ask how to calculate the probability of more than k units last probability? Seems (6/10)**k+1, but k=??
    The P0 is easy: 1-(6/10)=0.4

    Thanks for your amazing video. One thing is confused here, the definition shows that 'r'dont know how to type= mean number of arrivels per time period and mean number of people or items served per time period. But in your gas station example, why u used mins/car? it should be arrive is 10 cars/hrs, and serve 6 cars/hrs. so, the Ls should be -2.5 cars/hrs. So, my question here is how to explain the negative sign here, or we have to assume service rate have to larger than arrival rate.

    For the example about gas station, I guess the utilization factor is 10/6 = 1.66 and not 6/10 = 0.6

    Sir, your videos help a lot! A blessing indeed for us waiting to take CIE examination. I was wondering if you took the CIE? what advice can you give most especially in dealing Major Subjects like OR and POM?

    • @2334463
      @2334463  4 года назад +5

      Hi, Venice! Thanks for appreciating. Yes, I took the CIE Exam last 2015. For OR and POM, I would say really try your best to solve as much problem sets as you can. Most, if I can recall, were really problem-solving type of questions for both Module 3 and Module 4 where OR and POM belong. One of these days, I'll do my best to include POM for my tutorials. 😉

    Thanks for the video, quite insightful. I just had an issue with the question in the end, since , mu = 1/10, lamda = 1/6, after seeing the erratum, if I apply the following substitution in the Ws (1/mu-lambda) formula, I get a negative number, please help me proceed, thank you.

    • @crondog
      @crondog 2 года назад

      The formulas all break down when the utilization factor is greater than 1 (i.e. lambda > mu). This is because in a such a system the queue grows infinitely over time so all your averages will end up being infinite. I suspect there was a typo and the two rates got switched because as it is written the problem doesn't really have much meaning.

      Better to keep in rate in hr, there is no need in converting to mins.
