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

Ok… so you want to know the status of a specific shop order that was released two days ago.

What do you do?

It’s a sure bet that you have a manager, supervisor, or planner who can walk the floor and find the order at whatever work center it happens to be at. He/she can then answer “what operations have been completed and how many were completed?” All this requires leg work, and of course, a fair amount of time.

Now, if you have setup your BPCS master files properly, and you report transaction activity, you should be able to get those shop order statuses much faster using the SFC300 Shop Order Inquiry Screen.

At your fingertips you can see:

  • Release date & due date
  • How many hours remain in total and at each operation
  • The quantity required, what was finished and the remaining quantity
  • What components (materials) have been issued

Pretty basic information, right? Are you getting what you need to know? If not, then you may want to reexamine how your BPCS files are setup and what transactions along with their frequency are captured.

Role-Based Security introduces role type profiles and allows combining the use of role profiles with the traditional LX user type security profile functionality. The new role type profile can be defined to allow or deny access to All Products, Attention Key, Programs, and Transaction Effects.

Facility, Warehouse, and Company securities are still defined solely by the user profile settings and are not affected by the assignment of a role. Where applicable, the role authority is displayed alongside the user authority on the security profile maintenance screens making it easy to see where there are differences in authority between the user and the assigned roles.

When users are assigned to roles, security access in LX becomes a combination of authorities granted or denied by the role plus any user exceptions. User exceptions override authorities set by the roles. A user can also be assigned to more than one role.
