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 an Overnight Shift Wrap-Around in Scheduling?
An overnight shift wrap-around is how a scheduler handles a shift whose end time is earlier than its start. Learn the duration math and which calendar day the hours land on.
What Is Atomic Rollback in Production Scheduling?
Atomic rollback means a scheduling attempt that fails partway leaves zero residue: every booking it made is removed and the capacity it claimed is released.
What Is Drum-Buffer-Rope in Manufacturing?
Drum-Buffer-Rope is the Theory of Constraints method that paces a whole plant to its bottleneck. Learn the three parts and which of them a finite-capacity scheduler provides.
What Is Firming in Production Planning?
Firming turns a suggested build quantity into a real manufacturing order. Learn what firming commits, why it is idempotent, and how it differs from suggesting.
What Is Global Instance Assignment in Scheduling?
Global instance assignment keeps one job on the same machine instance for every shift it occupies on a work center, trading a little load balance for setup continuity.
What Is Greedy Scheduling in Manufacturing?
Greedy scheduling plans one job at a time, taking the earliest feasible slot at each step and never revisiting it. Fast, always feasible, and predictably suboptimal in one specific way.
What Is Open Quantity on a Sales Order Line?
Open quantity is what a customer is still owed: ordered quantity minus shipped, floored at zero. See how it drives firm demand and shrinks as shipments post.
What Is Override and Warn in Production Scheduling?
Override and warn is the contract where a planner can move any operation and the system flags the consequences without blocking the move. Learn what it does and does not check.
What Is Positional Column Mapping in a Data Import?
Positional column mapping reads each field from a numbered column instead of a heading name. Learn when a headerless file needs it and the risk it carries.
What Is Quantity on Hand in Inventory?
Quantity on hand is the current stock figure for a product, held as a cached total the ledger owns. Learn why you never type it and how it stays correct.
What Is Routing Drift in Production Scheduling?
Routing drift is the gap between the routing a job was scheduled against and the routing that is live today. Learn what the shop floor is told about it, and why the job keeps its own copy.
What Is Row-Error Tolerance in a Data Import?
Row-error tolerance decides whether one bad row fails alone while the import continues, or stops the whole run. Learn both behaviors and when to use each.
