What Is Cost Performance Index (CPI)? EDGEBIC Definition
Cost Performance Index (CPI) is earned value divided by actual cost. See the formula, a worked hours example, and how EDGEBIC computes and displays it.
What Is Dependent Parallel Processing?
Dependent parallel processing runs secondary machines in exact lockstep with a primary. Learn how mirroring works and when synchronized machines belong together.
What Is Earned Value in Manufacturing? EDGEBIC Definition
Earned value is the planned work actually completed, measured in hours. See the BAC, PV, EV, AC formulas and how EDGEBIC computes earned value per job.
What Is Firm Demand in Planning? Committed Orders Explained
Firm demand is committed, real demand from confirmed orders, as opposed to forecast estimates. Here is how firm demand drives requirements and promising.
What Is First Pass Yield (FPY)? EDGEBIC Definition and Formula
First pass yield is the fraction of units that pass inspection without rework. See the formula and how EDGEBIC uses it as the Quality factor inside OEE.
What Is FlowStep Overlap?
FlowStep overlap is a start-to-start lag in hours that lets a downstream step begin before the upstream step finishes. Learn how the lot-streaming lever works.
What Is Forecast Consumption in Demand Planning?
Forecast consumption is the rule that stops you counting the same demand twice when firm orders arrive inside a forecast period. Here is GreaterOf vs MinusConsumed.
What Is Independent Parallel Processing?
Independent parallel processing splits one operation across several machines that each check their own capacity, so the job finishes faster. Learn how it works.
What Is Last-Write-Wins Concurrency?
Last-write-wins is the concurrency model where the most recent save overwrites earlier ones with no conflict alert. Definition, the trade-off, and how it works in EDGEBIC.
Make-to-Stock vs Make-to-Order: What Is the Difference?
Make-to-stock builds ahead into inventory; make-to-order builds only after a customer order. Here is how the two policies differ and when each fits.
What Are Planned vs Actual Hours? EDGEBIC Definition
Planned vs actual hours compares scheduled hours against logged hours per machine per day. See the variance formula and how EDGEBIC computes and reports it.
What Is Projected Available Balance (PAB) in Planning?
Projected available balance is the running inventory forecast, bucket by bucket, after supply is added and demand subtracted. Here is how PAB works and reads.
