Production sequencing and scheduling with Gantt charts, capacity and machine load, demand forecasting and shift rosters; shortcuts to kanban, heijunka, bottleneck, OEE, product mix and operator hourly cost.
Paste jobs with family, time, setup and due date to compare FIFO, SPT, EDD, critical ratio and family grouping; see makespan, setup, tardiness, a Gantt chart in clock time and a printable dispatch list. Stages-in-series mode (2 to 8) with Johnson, NEH and CDS.
SPT, EDD, Johnson, NEHAssign jobs to several identical or different machines (speed, availability, allowed machines, family setups) or schedule a job shop with a different routing per job. Compare dispatch rules, see the Gantt chart by machine, each machine’s load and idle time, job waits, and print the dispatch list for each machine.
Parallel, job shop, GanttPaste the order book and machine list to compute hours required with scrap, efficiency and setups, each resource’s load with a traffic light, the bottleneck and what it costs to cover the shortfall with overtime, Saturdays, an extra shift, a new machine or outsourcing.
Load, bottleneck, overtimePaste 12 to 60 periods of demand to compare moving average, weighted average, exponential smoothing, Holt and additive and multiplicative Holt-Winters, with optimized parameters, MAD, RMSE and MAPE errors, bias and tracking signal, and a forecast for the next periods with an approximate confidence band.
Holt-Winters, MAPE, bandEnter 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, overtimeCalculate how many kanban cards and containers should circulate, maximum and average inventory, supermarket floor area, container weight and the capital freed compared with current stock.
Cards, containers, supermarketEnter each product’s daily demand, container size and available time: the calculator shows takt and pitch, builds the leveled sequence (goal chasing or proportional) and the day’s heijunka box by shift, and compares average inventory with batch production, along with EPEI and the changeovers needed.
Takt, pitch, box and sequenceIdentify the bottleneck step, calculate what an hour and a minute there are worth in throughput accounting and see the payback of elevating the constraint up to the next step or the market.
TOC, hourly value, next constraintCalculate OEE and TEEP from the six big losses, see the time waterfall and what each OEE point is worth, and compare improving OEE, adding a shift or buying a machine.
Availability, performance, quality, lossesEnter products with price, variable cost and demand, and the time each takes on up to 3 resources, to get the most profitable production mix, the bottleneck resource, the value of 1 more hour at each resource and a comparison with the current mix.
Optimal mix, bottleneck, shadow priceWork 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.
