Restaurant weighted table workload allocation calculator

Calculate work allocation and loads and unallocated tasks with your own figures.

Your numbers

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

Use work allocation and loads and unallocated tasks to compare changes to your inputs. The method and limits below explain the scope.

Examples

Examples

Try the starting example

Weighted table service efforts (work units)
8,6,5,3
Staff available workload capacity (same units)
60,60
Work allocation and loads (JSON)
{"assignments":[1,2,2,1],"loads":[11,11],"unassigned":[]}
Unallocated tasks (count)
0
Allocated workload
22

Try another scenario

Weighted table service efforts (work units)
9,8,6,4
Staff available workload capacity (same units)
50,40
Work allocation and loads (JSON)
{"assignments":[1,2,2,1],"loads":[13,14],"unassigned":[]}
Unallocated tasks (count)
0
Allocated workload
27
Calculation method

Calculation method

Work allocation and loads (JSON)

Largest-workload-first; assign feasible staff with currently lowest load, tie by index; preserve original task indices.

Unallocated tasks (count)

Count tasks that fit no remaining staff capacity in the greedy pass.

Allocated workload

Sum final staff loads.

Symbols and units
a
Weighted table service efforts (work units)
b
Staff available workload capacity (same units)

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

  • Tables remain indivisible; weights are user-estimated service effort, with interchangeable servers. Spatial adjacency 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. Positive work items and nonnegative staff capacities; <=100 items and <=20 staff. All listed staff qualify for all tasks; no time-window constraints unless encoded separately.
Are these inputs private?
