Hello,
I have a situation whereby we operate a capacity strategy of limiting to 85% consumption per week in an FMCG production environment in order to allow 15% capacity flexibility within the current week.
Our current capacity modelling setup in APO is as follows:
- ECC routing contains design speed of each product on the line (eg if nominal speed is 500 per min, this is declared in the routing regardless of actual line efficiency).
- SNP and PPDS PPMs also contain design speed (as shared by ECC routing)
- Each Resource (production line) is setup as a multi resource type
- The actual demonstrated efficiency of the line is maintained within the utilization % within the resource in order to model realistic output
in the past we have modelled the additional 15% capacity flexibility in the system through adding a 15% loss factor to the resource which effectively reduces the amount of available capacity which can be consumed by the SNP optimizer.
There are a few issues with this in terms of the reduction in capacity driven by the loss factor also affecting the PPDS planning board and effectively meaning that should the planner wish to utilise the reactive 15% capacity, they have not go space on the planning board and cannot add any jobs.
Another issue is that this approach effectively 'fools' APO into planning at an 85% utilization (ie if looking at capacity consumption within the capacity view for the resource, users will see 100% consumption rather than 85%)
For communication purposes I would like to inform the optimizer of all of the correct parameters but only have it plan deliberately to a max of 85% capacity consumption (after all of the utilization factors have been accounted for to model the line efficiency) eg if looking at the capacity view in the interactive SNP view, users should see a max of 85 hours consumed out of an available 100 in one given time bucket.
Thanks in advance for any guidance
Hi Ryan,
Have you tried with defining the overload % as 85%, so that system will always try not to plan anything more than 85% on a bucket?
