    If equip A is breakdown, then equip B will not have any parts to
    pack, so it has to stop operating. And if equip B is breakdown then
    equip A will stop producing any parts.Read it again. It will not have any parts to pack and so it has to
    stop operating. So B is available and A is not if A breaks down. Both machines do different activities…[Read more]

    Key word…. assume, assume, assume!If the machines are doing separate tasks and only one is dependent
    because it is serial, do not assume anything.When B breaks down and is not available, does that impact the
    availability of A in its OEE assessment… NO.

    So apply the process to your problem (your question). By not spending time, money, and resources on researching the
    question, defining the scope, measuring and analyzing so that you
    can get a good answer that can be sustained and validated with
    facts, any additional time spent on this question will waste your
    time, resources, and whoever…[Read more]

    Does not matter which one is the gated process because they are
    serial and must both be accomplished for the end goal. If A stops
    the process then you are in trouble. If B stops the process you are
    in trouble. He wanted to track OEE yet he does not want to track the one
    process because it is too tedious? So you recommended
    combining…[Read more]

    Z… ,To get it back to a constructive response, what is your reasoning
    behind telling the poster to ignore process B? If the Process is Tedious and possibly highly variable, how would
    you segregate this after combining A and B? How would you segregate other variability from other process that
    would have also been summed into your previous…[Read more]

    Could not tell you at this point to or not to look at this level because
    no one has given enough facts to tell me what is happening. Leaving
    the data blank and not understanding data does not mean there is or
    is not a problem.The original question was about OEE. If I find a problem, I would go
    to the intermediate steps and find the root…[Read more]

    Noooo… I was defending the real “Bubba” not the Z…. When Bubba
    has to pull your vehicle out of a ditch with his truck and tow chain,
    you start to be thankful. Plus I grew up in the south and have been to a lot of places where the
    people needed a lot more help. ; )

  • Vallee replied to the topic OEE calculation in the forum General 12 years ago

    Yep. Someone had to step up for Bubba… I was hoping Z… would step
    up and explain where the missing values needed to come from and
    what trigger you could go by to decide what was constraining based
    on the original post.HF Chris Vallee

  • Vallee replied to the topic OEE calculation in the forum General 12 years ago

    Oh darn algebra … but then I would also have to know more about
    the cycle time or I will be stuck with a lot more other letters like c,
    d , e and f. Can I combine that too?: 0It just bothers me when people will not look at a process because
    it is too much work. Often this is the place with the most
    variability. It is also frustrating…[Read more]

    Correction… add known value of A to “UNKNOWN” value of B and get what?

  • Vallee replied to the topic OEE calculation in the forum General 12 years ago

    So I don’t need to break down process B and track it because it is
    dependent on A…mmmmm Just combine them? I can add the known value of process A and the
    unknown value of process A and get what?

  • Vallee replied to the topic OEE calculation in the forum General 12 years ago

    Why does it always have to be Bubba? Why can’t it be Oscar or
    Hethro?HF Chris Vallee

  • Must understanding what data mining is before you can use it for
    anything. So is it just queries? What do the queries really mean? Why
    would you be performing a data mining project in the first place?Got to read the book first before you call it hype.

  • MBB,I am confused. You state that Isixsigma provides no value but you
    came here for advice??So you only like part of the site and not the whole site. It is like
    getting an award for part of the company and ignoring the rest of
    the company…. mmm!Not attacking you personally, just the logic in your thought
    process.

  • Simple, stop the process and you just shifted the mean. What’s more
    important.. it depends. Are you trying to safe lives, save a customer,
    or just improve or both. Special cause analysis and subsequent change can have a major
    impact to the mean. Common cause can be commonly impacted by
    target proactive audits. So what’s critical, what’s…[Read more]

    Mike,
    You have time to watch TV and can afford cable….. what’s the
    problem? HF Chris Vallee

  • Vallee replied to the topic Breyfogle vs. Wheeler in the forum General 12 years, 4 months ago

    The biggest question in all this is what is the risk of uncertainty?
    You have two models:1) Fit the sample to the model
    2) Fit the model to the sample On one hand the forcing the sample can lead to a very non-
    predictive model for the future samples while forcing the model to
    the sample can lead to ambiguous models that are not robust. So…[Read more]

  • Nice…. now you are making the box more complicated to get out off.
    The off the shelve cardboard box was hard enough and the cat kept
    using it as a litter box.

  • Oh…. now you want money inside the box too?!

  • Let’s call it tunnel vision…. wait that only applies when you are in a
    tunnel.We can say there needs to be a paradigm shift…. but what are
    shifting?I give up… guess I’m stuck in my box, cube…. how do I get out of it?
