    I would like to plan the production operations based on the available personnel. We normally have more work centers than employees, but each work center requires an operator (employee) in order to run. How can we limit the machine planning to be process only if there is an available employee?

    Thanks

    Hi Boris,

    MxAPS has secondary constraints to represent things like labor and tooling.  The setup for that would be as follows:

    1)  You create a Shop Calendar and when defining the working days and times we have a added an additional field where you can specify the quantity of operators available.

    2)  Create an item to represent the pool of operators.  In the MxAPS FastTab assign it the Shop Calendar you just created, and set the constraint tracking to constrain based on the availability of the item.  You would also need to set the time period over which the constraint applies by making sure the Fence Type is set to item and then entering a duration in the Lead Time Calculation in the Replenishment FastTab (past this time the system is allowed to go negative, so if this should never happen use a large value like 999 days).

    3)  Assign the new item to a work center or machine center in the Machine Constraints page.  The From Segment and To Segment allow you to define when the operator is needed.  For example you may only need an operator during the Setup activity or you may need them from the Setup to the Run.  The Release Segment defines if and when the constraint item is replenished, which is typically the case for an operator or a tool, and is typically the same value as the To Segment.  Finally the Logic determines if a fixed quantity of the secondary constraint item is needed or if it depends on order quantity.

    Hi Mark,

    Thanks for your detailed reply.

    I could not find the additional filed in the Shop Calendar however. Is this a feature to be activated or should be already added?

    In the Item’s MxAPS FastTab I can assign only a particular Shift Code and not the Shift Calendar which would be limiting the capacity to only particular machine, I suppose, and won’t allow constraint of multiple people using multiple machines.

    Thank you

    Hi Boris,

    The field you need is not on the page by default, so you’d need to use the Settings->Design option on the Shop Calendar Working Days page and add the “Available Resources” field to the view.

    Also, I checked and you are correct, the lookup on that field in the Item card in the extension version you have is not pointing to the correct table.  This has been corrected for the upcoming version 4.2 release which is in testing currently.

    Its not visible in the Personalize tab either, so I guess we should run the designer as you suggest.

    If it’s only the lookup, I suppose that entering manually the correct reference would do the work. Not sure if we otherwise can use the 4.2 version before release.

    Thank you

    Boris
