Infor LX & BPCS Manufacturing Tip: 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.

Backward scheduling is supported in all shop order release programs (SFC500, SFC550, and FAS510). Backward scheduling is recalculated if a shop order is maintained through SFC500 when the due date or the required quantity is changed; however, you cannot enter move and queue times through the maintenance program when adding an operation to the shop order.

Tips:  LX | BPCS | M3

When is the last time you took a hard look at your production lines?
 
  • How are we moving product through our facility?
  • Do we have work instructions / drawings available where needed?
  • Do we have frequently used inventory available at the line?
  •  
  • Where are the bottlenecks?
  • Are processes automated, where possible?
 
Taking a hard look at your processes and procedures may reveal some interesting results.  

Don’t assume that everyone is doing things the same way. Some may be superstars, and others may need some mentoring. Some processes may be outdated and costing you time and money, while others are extremely efficient. One area of the business may benefit from how others operate. Take the time to review and analyze your findings. Your company may benefit greatly as a result.

Shop Order status codes have been improved to provide a more comprehensive view of the life cycle of a shop order.

In addition to the previously existing ‘Shop Order Status Code’, the Production Status Code has been added. This code is designed to indicate progress and completion levels of each shop order.  Valid codes are:

‘blank’ - no completed items

25 - a partial quantity has been reported

35 - the quantity reported is equal to or greater than the order quantity
