The Bullwhip Effect on Your CPG Line: Why a 5% Shelf Wobble Becomes a Whipsawing Schedule
Your inbound order signal swings harder than consumers actually buy. That jumpiness is a structural amplification called the bullwhip effect. Here's how to name it, measure it, and dampen it from the plant floor.

Little's Law for CPG Schedulers: Predict Line Lead Time from WIP and Throughput
The line is running at rate, yet orders keep shipping late. Little's Law explains why: lead time is WIP divided by throughput. Learn to predict flow time, cap queues, and quote promise dates you can keep.

The 100% Utilization Trap: Why a Fully Booked CPG Line Is Your Slowest Line
Loading a line to 98% of available hours looks efficient, but queue time explodes as you approach 100% utilization. Here's the math behind the trap and where to set your utilization ceiling.

Tracking Signal: Catch a Biased Forecast Before It Corrupts Your Schedule
A forecast rarely fails loudly — it drifts. Learn how the tracking signal, a cheap MAD-based trip-wire, flags persistent forecast bias so you can fix it before it inflates run sizes or triggers repeat stockouts.

The Newsvendor Model: How Much to Make for a One-Shot CPG Run
Holiday packs, LTOs, and short-code items give you exactly one shot at the run quantity. The newsvendor model turns overage-vs-underage costs into a defensible batch size using one number: the critical ratio.

Dynamic Lot-Sizing for Lumpy CPG Demand: When One Fixed Batch Size Stops Working
EOQ and EPQ assume steady demand. Real CPG demand is lumpy — promo spikes, seasonal resets, uneven retailer orders. Here's how lot-for-lot, POQ, Silver-Meal, and Wagner-Whitin size runs when net requirements change every week.

Economic Production Quantity (EPQ): Sizing Batches When Your Line Makes and Ships at Once
Run long to dilute a painful changeover, or run short to avoid drowning in inventory? EPQ is the math for the sweet spot — built for a line that fills stock gradually while demand keeps pulling it down.

Takt Time for CPG Schedulers: Turn Demand Into a Daily Run Plan
Takt time is the customer's drumbeat — the pace demand sets, not the pace your line can hit. Here's how to calculate it, reconcile it with run-rate, and turn it into a daily run plan that actually holds fill.

Plan to Real Capacity, Not Nameplate: Turning OEE Into a Schedulable Run-Rate
Schedulers build the master plan against a line's nameplate rate, then watch it slip. OEE is the translation layer between theoretical speed and the number you can actually schedule against. Here is the arithmetic and the levers.

Shelf-Life-Constrained Production Scheduling: Sizing Runs So Perishable SKUs Don't Expire
Classic lot-sizing math quietly assumes product lives forever. In food and beverage it doesn't. Here's how to cap production runs at the shelf-life-feasible quantity so perishable SKUs sell before they expire — without stocking out.

Rough-Cut Capacity Planning for CPG: Pressure-Test the Master Schedule Before It Hits the Floor
RCCP is the fast feasibility check that sits between master scheduling and MRP. Learn how to load your MPS against real filler, tank, and labor capacity before you promise dates you can't build.

Time Fences for CPG Schedulers: Where to Freeze, Where to Flex
Schedule nervousness thrashes the floor when every late change rebuilds the week. Learn how to divide your planning horizon into frozen, slushy, and liquid zones, size the freeze to your cumulative lead time, and enforce the rules that keep the plan stable.

Run Order Matters: Sequencing SKUs to Slash Total Changeover Time
You can't always make each changeover shorter, but you can make fewer of them expensive. Here's how to build a changeover matrix and sequence your SKUs to cut total cleandown time across the whole run.

ABC-XYZ Segmentation for CPG: Which SKUs Deserve Tight Scheduling and Safety Stock
You can't manage 400 SKUs the same way. Learn how ABC-XYZ segmentation ranks SKUs by dollar impact and demand variability, so you spend scheduling attention and safety stock where they actually pay off.

Drum-Buffer-Rope: How to Schedule a CPG Line Around Its One True Bottleneck
Most CPG schedules fight the wrong machine. Learn how Drum-Buffer-Rope builds the production schedule around your line's real constraint to protect throughput and ship dates.

EPEI (Every Product Every Interval): How Often Should Your Line Make Each SKU?
EPEI is the one number that names your production rotation — how often each SKU comes around. Here's what it means, why smaller is usually better, and how to calculate and shrink it on a real CPG line.

Heijunka for CPG Lines: Turning Lumpy Demand Into a Schedule the Floor Can Run
Forecasting tells you how much to make. Heijunka tells you in what rhythm and sequence. Here's how production leveling smooths lumpy CPG demand into a repeatable schedule that protects fill rate and your changeover budget.

The hidden cost of changeovers
Two plans can make the same units in the same week and cost very different amounts to run. The gap hides in the changeovers — and there's a discipline for closing it.
