Insights on production scheduling, lean manufacturing, and manufacturing software from 35+ years of industry experience.
How the platform actually works: scheduling, optimization, the shop floor and ERP data.
What Is Backlog in Capacity Scheduling? EDGEBIC Definition
Backlog is the forward sum of remaining hours a work center still owes. See how EDGEBIC's Resource Calendar burns a step down 24 to 16 to 8 to 0.
What Is Budget at Completion (BAC)? EDGEBIC Definition
Budget at Completion is the total planned work fixed when a job is scheduled. See how EDGEBIC uses BAC as the earned value baseline for SPI, CPI, and EAC.
What Is End-Item Lead Time in Scheduling?
End-item lead time is the delivery, cure, or ship tail after the last machine operation. It splits the item start date from the job end date and consumes no work-center capacity.
What Is Estimate at Completion (EAC)? EDGEBIC Definition
Estimate at Completion forecasts a job's final hours from its efficiency so far. See how EDGEBIC computes EAC from BAC, earned value, and the cost index.
What Is Factor-from-Base in Work Center Groups?
Factor-from-base means a machine's speed factor always applies to the original planned hours, never to last run's already-factored hours, so factors never compound across reschedules.
What Is Group Explosion in Scheduling?
Group explosion converts a machine-pool routing step into one nominal machine plus a candidate per member just before selection, so the core engine never sees a group.
What Is Password Hashing?
Password hashing stores a one-way fingerprint of a password instead of the password itself. Learn how EDGEBIC uses PBKDF2 with SHA-256 to protect sign-in credentials.
What Is Percent Complete in Manufacturing Scheduling? EDGEBIC
Percent complete measures how far along a job is by hours, not steps. See how EDGEBIC rolls a job's actuals up to its end item without double-counting.
What Is Performance Rate in OEE? EDGEBIC Definition
Performance rate is the OEE speed factor: actual pieces over theoretical pieces. See how EDGEBIC computes it from BOR cycle time and efficiency factor.
What Is Phantom Capacity in Scheduling?
Phantom capacity is fake schedulable hours no physical machine backs, created when a machine pool is treated as a resource itself. Learn how good scheduling design avoids it.
What Is Quality Rate in OEE? EDGEBIC Definition
Quality rate is the OEE factor for good output: good pieces over total pieces. See how EDGEBIC computes it from production punches and shows n/a without them.
What Is Re-Shopping in Work Center Group Scheduling?
Re-shopping is when a not-yet-started group step picks a machine again on reschedule against current capacity, while started work keeps its machine. Here is how it works.
