The scheduling and allocation of resources for a production order can be done not only on the scheduling page but also on the Production Orders page. In this article, we'll check which options are available when editing a production order.
1. Assign workers and machines to each operation
This option triggers an extra link on each product on your production orders.
Here, workers and machines can be assigned, just like on the scheduling by operation screen. Beware that, this will impact the scheduling and its load calculations, but won't have any impact on the tablet. In other words, when you assign an operation to a worker or machine, other workers and machines can also perform it.
If you'd like to have this feature enabled, please contact your account manager or the support team.
2. Disable specific operations on specific production orders
You may also indicate that not all operations are to be performed by clicking on the tick boxes on the left side of the screen. The selection of operations is reflected on the tablet.
Moreover, beware that the last operation should always be enabled. This will ensure your production order progress and the generated inventory are accurately tracked. If you would like to use this feature, please contact your account manager or the support team.
3. Apply the "magic wand"
The magic wand is a feature that provides the expected start date or end date for a production order, assuming that the allocated resources are always available, and that operations are performed consecutively.
The "magic wand" takes the time per operation for the calculations either from the operation cycle time + quantity ratio (1) or operation lead time (2).
To better understand this feature, three examples are provided: two examples with different complexities (considering the cycle time + qtt ratio), and one considering the operation lead time.
In all, the quantity ordered is 8 and the product is Chocolate Cake.
This product contains 3 operations:
Mixing (takes 45 minutes per unit)
Baking (takes 35 minutes per unit)
Packaging (takes 1 hour per 6 units)
There are 3 workers:
Workers 1 and 2, with a shift going from Monday to Friday (8AM - 12PM, 1PM - 5PM)
Worker 3, with a shift going from Monday to Thursday (8AM - 12PM)
Example 1
In this example, all three workers are assigned to the production order, but none of them is assigned to any specific operations within the production order. The system will therefore check the most used shift within these three workers and consider it for scheduling all the operations of this order over time.
Considering the start time on Feb 29th, at 8:00AM, and the most used shift (Monday to Friday from 8AM - 12PM and 1PM - 5PM), Fusion Operations will place the order ending on March 1st, at 12PM.
The scheduled time for each operation is as follows:
Mixing (6 hours)
takes 45 minutes / 1 unit * 8 units = 360 minutes (6 hours)
shift considered is Monday to Friday (8AM - 12PM, 1PM - 5PM)
starts on Feb 29th at 8:00AM, ends on Feb 29th at 3:00PM
Baking (4 hours and 40 minutes):
takes 35 minutes / 1 unit * 8 units = 280 minutes (4 hours and 40 minutes)
shift considered is Monday to Friday (8AM - 12PM, 1PM - 5PM)
starts on Feb 29th at 3:00PM, ends on Mar 1st at 10:40AM
Packaging (1 hour and 20 minutes):
takes 60 minutes / 6 units * 8 units = 80 minutes (1 hour and 20 minutes)
shift considered is Monday to Friday (8AM - 12PM, 1PM - 5PM)
starts on Mar 1st at 10:40AM, ends on Mar 1st at 12:00PM
Example 2
In this example, some workers are allocated to scheduled operations: no workers are assigned to operation Mixing, worker 3 is assigned to operation Baking, and all three workers are assigned to operation Packaging.
Considering the start time on Feb 29th, at 8:00AM, and the most used shift regarding the workers associated with each operation, Fusion Operations will place the order ending on March 5th, at 9:06AM.
The scheduled time for each operation is as follows:
Mixing (6 hours)
takes 45 minutes / 1 unit * 8 units = 360 minutes (6 hours)
shift considered is Monday to Friday (8AM - 12PM, 1PM - 5PM)
starts on Feb 29th at 8:00AM, ends on Feb 29th at 3:00PM
Baking (4 hours and 40 minutes):
takes 35 minutes / 1 unit * 8 units = 280 minutes (4 hours and 40 minutes)
shift considered is Monday to Thursday (8AM - 12PM)
starts on Feb 29th at 3:00PM, ends on Mar 5th at 8:40AM
there's no work on Feb 29th since worker 3 doesn't work in the afternoons.
note that March 1st is Friday, and therefore worker 3 isn't working on that day.
note that the operation ends Tuesday because worker 3 works 4 hours only in the morning, preventing the operation from being completed on Monday, March 4th.
Packaging (1 hour and 20 minutes):
takes 60 minutes / 6 units * 8 units = 80 minutes (1 hour and 20 minutes)
shift considered is Monday to Friday (8AM - 12PM, 1PM - 5PM)
starts on Mar 5th at 8:40AM, ends on Mar 5th at 9:06AM
note that this operation is scheduled for 3 workers. Therefore the system considers the three will be performing it simultaneously, and its duration is 1h20m/3 = 26m
Example 3
Same as example 1, but the lead time of the operation Baking is 2 days:
Mixing (takes 45 minutes per unit)
Baking (lead time of 2 days)
Packaging (takes 1 hour per 6 units)
Considering the start time on Feb 29th, at 8:00AM, and the most used shift (Monday to Friday from 8AM - 12PM and 1PM - 5PM), Fusion Operations will place the order ending on March 4th at 4:20PM.
The scheduled time for each operation is as follows:
Mixing (6 hours)
takes 45 minutes / 1 unit * 8 units = 360 minutes (6 hours)
shift considered is Monday to Friday (8AM - 12PM, 1PM - 5PM)
starts on Feb 29th at 8:00AM, ends on Feb 29th at 3:00PM
Baking (2 days):
takes 2 days (independent of the quantity ordered) = 2 days (4 hours and 40 minutes)
shift considered is Monday to Friday (8AM - 12PM, 1PM - 5PM)
Weekend is from Mar 2nd to Mar 3rd
starts on Feb 29th at 3:00PM, ends on Mar 4th at 3:00PM
Packaging (1 hour and 20 minutes):
takes 60 minutes / 6 units * 8 units = 80 minutes (1 hour and 20 minutes)
shift considered is Monday to Friday (8AM - 12PM, 1PM - 5PM)
starts on Mar 4th at 3:00PM, ends on Mar 4th at 4:20PM
