Envelope penetration collar inventory calculator

Calculate compatible instance assignments and unassigned penetration instance IDs with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use compatible instance assignments and unassigned penetration instance IDs to compare changes to your inputs. The method and limits below explain the scope.

Examples

Examples

Try the starting example

JSON Penetrations [ID,diameter mm,integer quantity]
[["A",80,2],["B",120,2]]
JSON Products [ID,inclusive minimum mm,inclusive maximum mm,stock count]
[["small",50,100,3],["large",90,150,1]]
Compatible instance assignments
[["A#1","small"],["A#2","small"],["B#1","large"]]
Unassigned penetration instance IDs
["B#2"]
Allocated product quantities
[["small",2],["large",1]]

Try another scenario

[["A",80,2],["B",120,2]]
JSON Products [ID,inclusive minimum mm,inclusive maximum mm,stock count]
[["small",50,100,3],["large",90,150,2]]
Compatible instance assignments
[["A#1","small"],["A#2","small"],["B#1","large"],["B#2","large"]]
Unassigned penetration instance IDs

Calculation method

Calculation method

Compatible instance assignments

Expand penetration quantities and exact matching by inclusive product diameter ranges and stock capacity.

Unassigned penetration instance IDs

Maximum-matching shortages.

Allocated product quantities

Count assigned instances by product ID.

Symbols and units
a
JSON Penetrations [ID,diameter mm,integer quantity]
b
JSON Products [ID,inclusive minimum mm,inclusive maximum mm,stock count]

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • Entered product diameter ranges and compatibility are authoritative inputs; diameter fit alone does not certify fire, water or system performance. Supported limits: At most 100 penetration instances and 200 total product stock seats.
Are these inputs private?
