Time study and standard time, work sampling, ILO allowances (fatigue and personal needs), man-machine ratio, labor efficiency, staffing, skills matrix (cross-training), learning curve and spaghetti diagram.
Paste your stopwatch readings and check whether the sample is sufficient, then get normal time with the performance rating, standard time with allowances and output per hour and per shift.
Sample size, rating, allowancesPlan how many snap observations to take for the precision and confidence you want, generate random round times, enter counts by category and day and get each activity’s share with confidence interval, whether precision was reached, a daily p chart and the standard time.
Snap readings, rounds, p chartAnswer the ILO relaxation allowance questionnaire (personal needs, basic fatigue, standing, posture, weight lifted, lighting, atmospheric conditions, close attention, noise, mental strain, monotony and tediousness) and get the total, the standard time, the workday-share conversion and an item-by-item justification PDF.
Personal, fatigue, postureEnter load/unload, automatic and walking times to find how many machines one operator can tend: N₀, cycle time, parts per hour, operator and machine idle time, cost per part from 1 to N₀ + 2 machines and the man-machine chart. Mode for machines with different times.
Machines per operator, N₀Enter available hours, downtime and output by item with standard times for each operator, cell or shift and get utilization, efficiency, overall efficiency, hours and cost of losses, a Pareto by reason, a ranking with alerts and a production bonus simulation.
Standard hours, utilizationCalculate how many people you need to keep positions staffed on every shift, with contracted hours, vacation, holidays, absenteeism and training, and the gain from reducing absences.
Coverage factor, shifts, absenteeismFill in or paste the people × stations matrix with ILUO levels and see how many qualified people each station has against the minimum, exposed stations, key people, the multi-skill index, a training plan with hours and trainers, rotation at ergonomic-risk stations and a board-ready PDF.
ILUO, coverage, trainingEnter first-unit time and learning rate to get unit n time, batch total and average, the unit where standard time is reached and labor cost, under the Wright and Crawford models; fit the rate by pasting actual times (log-log regression).
Wright, Crawford, batch costEnter the locations with x, y coordinates in the current and proposed layout and the moves between them (per cycle or per day): the calculator draws the spaghetti diagram, adds up distance per cycle, day and year, turns it into walking hours and cost and shows the saving of the new layout.
Distance, time, layoutWork out the fully loaded cost of a production operator: wage, overtime, night shift differential, employer FICA, unemployment and workers’ comp, retirement match and benefits, with cost per paid hour, per productive hour and a day vs. night shift comparison.
Burden, shifts, per hourEnter operating days, hours and positions (or custom shifts), tick the schedules to compare (5x2, 6x1, 4x2, 6x2, 12/36, 2-2-3, Continental, 24/72 or custom) and get people per team with vacation and absences, rounding and optimization, hourly coverage, overtime, freelancers, 4-week calendars and monthly cost.
Teams, 2-2-3, coverage, overtimeCompute the recommended weight limit (RWL) and lifting index with the revised NIOSH equation, with horizontal, vertical, travel, asymmetry, frequency and coupling multipliers at origin and destination.
RWL, lifting indexPick the angle ranges for the upper arm, lower arm, wrist, neck, trunk and legs on both sides, plus muscle use and force, and get the RULA table A, B and C scores, the action level, a posture figure, what to change to drop a level and a workstation comparison, with a PDF record.
