Salon fixed-phase skill assignments calculator

Calculate qualified fixed-start allocation [item,staff,start,end] and uncovered work items with your own figures.

Your numbers

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

Use qualified fixed-start allocation [item,staff,start,end] and uncovered work items to compare changes to your inputs. The method and limits below explain the scope.

Examples

Examples

Try the starting example

Phases [start minute,duration minutes,required qualification code]; enter JSON
[[0,30,"A"],[10,20,"B"],[40,20,"A"]]
Staff [skill-code array,[[available start minute,end minute],...]]; enter JSON
[[["A","B"],[[0,90]]],[["A"],[[0,90]]]]
Qualified fixed-start allocation [item,staff,start,end] (JSON)
[[1,1,0,30],[2,null,10,30],[3,1,40,60]]
Uncovered work items (count)
1

Try another scenario

Phases [start minute,duration minutes,required qualification code]; enter JSON
[[0,40,"A"],[10,30,"B"],[35,30,"A"]]
Staff [skill-code array,[[available start minute,end minute],...]]; enter JSON
[[["A"],[[0,60]]],[["B"],[[0,60]]]]
Qualified fixed-start allocation [item,staff,start,end] (JSON)
[[1,1,0,40],[2,2,10,40],[3,null,35,65]]
Uncovered work items (count)
1
Calculation method

Calculation method

Qualified fixed-start allocation [item,staff,start,end] (JSON)

Stable start order; choose lowest-index staff with required supplied skill, containing availability window, and no occupied overlap; null if none.

Uncovered work items (count)

Count null staff assignments; no alternate-start search.

Symbols and units
a
Phases [start minute,duration minutes,required qualification code]; enter JSON
b
Staff [skill-code array,[[available start minute,end minute],...]]; enter JSON

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

  • Each service phase has fixed start and required user-supplied qualification code; senior supervision is not inferred. 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. <=100 items, <=20 staff; positive durations; interval starts<ends; skill labels exact case-sensitive matches.
