Restaurant equipment workload capacity comparison calculator

Calculate station utilization before and after and largest proposed utilization with your own figures.

Your numbers

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

Use station utilization before and after and largest proposed utilization to compare changes to your inputs. The method and limits below explain the scope.

Examples

Examples

Try the starting example

Stations [name,required cycles,cycle minutes,parallel existing units,proposed extra units]; enter JSON
[["Oven",20,12,2,1],["Fryer",30,5,1,1]]
Available operating window (minutes)
120
Station utilization before and after (JSON)
[["Oven",1,0.666666666667],["Fryer",1.25,0.625]]
Largest proposed utilization
0.666667

Try another scenario

Stations [name,required cycles,cycle minutes,parallel existing units,proposed extra units]; enter JSON
[["Oven",30,10,2,1],["Fryer",40,6,1,2]]
Available operating window (minutes)
150
Station utilization before and after (JSON)
[["Oven",1,0.666666666667],["Fryer",1.6,0.533333333333]]
Largest proposed utilization
0.666667
Calculation method

Calculation method

Station utilization before and after (JSON)

Required work=cycles×cycle minutes; utilization=work/(window×parallel units); after adds proposed units.

Largest proposed utilization

Maximum station utilization after candidate additions.

Symbols and units
a
Stations [name,required cycles,cycle minutes,parallel existing units,proposed extra units]; enter JSON
b
Available operating window (minutes)

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

  • Independent appliance workload-capacity comparison over a user window; no workflow coupling or safety rating inference. Supported limits: All numeric inputs and computed intermediates must remain finite. Supported numeric input magnitude is zero or 1e-12 through 1e12 in absolute value; reject values outside this bounded range. All lists/JSON record tables are limited to 100 records unless a stricter bound is stated; reject malformed record arity and wrong member types. Existing units positive integer, additions integer>=0; cycle minutes and window>0. Utilization>1 indicates aggregate workload deficit; values<=1 do not prove schedulability.
Are these inputs private?
