How to plan operations without intermediate pauses

[matteocarcano]

Hi,
i would like to ask you how can I set model to plan operations only if they can start and end in the same daily bucket.
e.g.: daily working hours: 6.00 am - 10.00 pm.
There's one operation that starts at 8.00 am and finishes at 4.00 pm, so there are only 6 hours free available. How can i set Frepple as it plans an operation only if its duration is less than 6 hours? This because started operation can't stay idle during the night pause.

Thank you in advance.

bye

You can use a "maximum calendar" for your resources, and make sure that the capacity is 0 during off-shift periods.

There is a subtle difference between the "available calendar" and "maximum calendar": A manufacturing order can be planned across an unavailable period and it's duration will be "strethed" for the unavailable time (ie you start today and finish it tomorrow). But a manufacturing order can NOT be planned across a period where the resource max size is 0.

There is also a danger with a "maximum calendar". If you set the max size to 0 each day during the night, we will not be able to plan an operation that takes eg 48 hours. We'll never find a period of 48 hours where the resource size stays above 0, and your demands will get unplanned.
