Module 02 - Manufacturing
Most stock systems assume you build the same thing repeatedly. If you build to order, the interesting part is the deviation: the customer change on hull 47 that must not propagate to hull 48. DKayMRP is built around that distinction rather than apologising for it.
01Bills of materials
The blueprint BOM is the design as it stands. When an order is confirmed it takes its own copy, and from that point the two are separate. Engineering keeps improving the blueprint; the order in build keeps the parts it was quoted on.
02Work orders
Demand becomes executable work orders with their materials, their sequence and the station they belong to. Operators see the job in front of them and the components it needs, without a paper traveller going soft in someone's back pocket.
03Execution
Material issued to a job leaves the shelf in the same step it joins the order, and labour is booked against the operation it was spent on. Both are movements in the same ledger inventory already uses, which is what makes the costing add up later.
04Costing
Materials consumed, labour booked and the change orders in between roll up into the cost of that specific order. The expensive part of engineer-to-order work is the change, so the change is where the costing starts rather than an adjustment bolted on at the end.
Confirmation copies the blueprint BOM onto the order. Later design changes do not reach back into a build already underway.
The copy explodes into work orders, operations and the material each one needs, sequenced by station.
Material is issued and labour is booked against the operation, both landing in the same ledger as every other movement.
Materials, labour and every change order roll up into what this build cost, next to what it was quoted at.
If your product is the same every time, almost any MRP will do. This module exists for the manufacturers whose product is not.
Your factory has a rhythm. Let us find it.
