To calculate remaining production time

When the production has started, the remaining production time is gradually reduced, until the operation has been fully completed.

The way in which LN calculates the remaining production time depends on the setting of the Calculation Method Remaining Production Time field in the Shop Floor Control Parameters (tisfc0100s000) session. In this field, you can select the following calculation methods:

  • Planned Quantity
  • Time Spent
Calculation method: planned quantity

If this field is set to Planned Quantity, LN applies the following formula to calculate the remaining order quantity:

[...]

Next, LN uses the value of the remaining order quantity to calculate the production time, which is also the remaining production time. Refer to the relating topic for details about the methods LN applies to calculate the (remaining) production time.

Calculation method: time spent

If the Calculation Method Remaining Production Time field is set to Time Spent, LN takes the following steps to calculate the remaining production time:

  1. Calculate the spent hours according to the following formula: total man hours + total machine hours.
  2. Calculate the total hours according to the following formula: total planned man hours + total planned machine hours.
  3. Calculate the remaining production time with the values found in the previous two steps:
[...]
