Infor LX & BPCS Manufacturing Tip of the Week: Backward Scheduling

Operations are automatically backward scheduled at shop order release time. The backward scheduling algorithm starts with the shop order due date and schedules each operation based upon the standard move and queue times in the routings and the number of days the job is expected to run at standard. The system calculates and stores the operation scheduled start date. The dates may be modified by the shop order maintenance program. The number of days that a job is expected to run an operation is dependent upon the available capacity for that work center and the total hours scheduled for that operation.

The backward scheduling algorithm also considers the shop calendar for weekends, shutdowns, holidays, and partial days.

Backward Scheduling Process

The algorithm starts with the due date of the shop order or planned order. The system makes the following calculations for each operation in the reverse sequence:

  1. The number of move days is subtracted from the due date (or initial date of the previous operation) to get the due date for this operation. The move days are only used on valid shop calendar days.
  2. The system uses the following calculation for the number of clock hours for the operation: Standard run or machine hrs/No. of operators + setup hours
  3. The number of clock hours is spread over the available daily capacity of the work center for those given days. The system uses the following calculation for the daily capacity of the work center: Number of shifts x hours per shift x average efficiency/100
  4. Each day is checked against the shop calendar; the calculation bypasses inactive days or adjusts for any changes in the work center capacity for that day.
  5. Queue time days are subtracted in the same manner as move time days. The resulting date is the operation start date.

The algorithm then goes to the previous operation. When all operations have been included, the resulting date is the scheduled start date of the shop order. Note that MRP uses the item lead time to determine material requirement dates on planned orders.

Tips:  LX | BPCS | M3

Congratulations! You bought that shiny, new car! It has all the features you can possibly want and goes a million miles an hour. It can take you anywhere your heart desires…….but you rely on a manual scooter to get you around. You know, the kind you had when you were a kid…BEFORE you could drive…before you could afford the BMW. Make sense? Uh... no.

You’d never do this, right? So, why are you doing this with the ERP system that runs your business? Why are you relying on spreadsheets and separate little Access databases to record and store the information that is the most critical to your business when you have an ERP system that is meant for this? Why continue to plod along at a snail's pace when you have the tools to take your business to the next level?

Your ERP system is your BMW. Use it. See what it can do for you. Think you’ve used it to its potential? Unlikely. We’ve helped customers breathe new life into their EXISTING ERP version all by unlocking functionality for them that was already there and ready to use! We’ve also helped by offering add-ons to the ERP that can make your productivity skyrocket.

Ask us how. We’ve got an extra set of keys to the BMW in case you lost yours.

  1. Identify the key metrics. You need benchmark data so you know what realistic goals are, then track them and publish your performance along with a brief comment from time to time on how things are trending and how you compare with others, particularly your primary competitors. The best thing about this is that it is a system that develops a life of its own.
     
  2. Measure it. Automatically, people start to think about improving things. Then the fun part, stuff begins to improve by itself. Once in place, the system just hums along and the benefits appear, because it has motivated people to think about it, and figure out what they can do to make it better.
     
  3. Communicate it. Publish your numbers, and explain to people how what they do affects the company as a whole and its success/failure. Once they see the numbers, employees quite often start to modify their behavior for the better.
