Production planning and delivery coordination · Lesson 3 of 4

Production planning and delivery coordination: methods and worked application

A backward schedule worked from the install date, the AFS next-business-day booking rule with its weekend and time-zone traps, the four delivery windows, bundle sequencing by area and what the customer is told.

You will be able to: Build a backward schedule from an install date, apply the AFS next-business-day delivery rule on the shop clock, choose a delivery window, sequence and label bundles by install area, and tell the customer what was booked.

Plan backward from the install

Plan backward: start from the day the crew needs the material, then subtract each step.

Because AFS books delivery for the next business day after a job is marked finished, work back one business day from the delivery day to find the finish day.

Each step starts when the one before it ends.

Correct and incorrect: booking delivery against the install dateTwo panels. Wrong, marked with a cross: pieces finished Friday, the crew starts Monday at 7 AM, the delivery is booked in the Monday 8 to 10 window so the crew waits; or pieces delivered in week 1 for an install in week 3 and stored on site.

Two panels. Wrong, marked with a cross: finished Friday, the crew starts Monday at 7 AM and the delivery is booked in the Monday 8 to 10 window so the crew waits; or delivered in week 1 for an install in week 3 and stored on site. Right, marked with a check: finished Thursday, delivered Friday, install starts Monday.

Book backward from the install start. Delivery on the next business day after the finish is the AFS rule; a Monday morning window cannot serve a Monday 7 AM crew.

Glossary

Backward schedule
A schedule worked from the day the crew needs the material back through each earlier step. At AFS the finish day is the business day before the delivery day.
Business day
At AFS, Monday to Friday. A delivery is booked for the next business day after a job is marked finished, so a Friday, Saturday or Sunday finish is booked for Monday.
Delivery window
One of the four two-hour periods AFS books a delivery in: 8–10 AM, 10 AM–12 PM, 1–3 PM and 3–5 PM. An auto-booked delivery gets the first.
Pull
In the Last Planner system, asking a supplier to deliver an input when it is needed, for example materials for one area before another.
Expedite
In the Last Planner system, getting selective attention from a supplier to remove a constraint when the expected lead time is too long.
