Topic:   Manufactured Items

I have a machine shop. I need a category of items called "Manufactured." The item will need raw material, a block of steel. The item will need to be routed through multiple work centers, for periods of time, at a cost per unit time. Does MiniMRP support manufactured items, work orders, routings, and costing? I have the trial download and in setting up a part number I have not found a way to support this?

MiniMRP is mainly a planning and inventory tool. You tell it what you want to build and it tells you whether you have enough components to do the job. if you don't have enough it tells you what you need to buy/produce and when you need to buy it.

So let's say, for arguments sake, you build and sell lawnmowers.

You would have an assembly called "LawnMower" and that would have a parts list showing all the components, nuts and bolts to build a lawnmower. This list would also contain sub assemblies. So a sub assembly for the bodywork. Another for the engine etc.

So when you want to build 5 lawnmowers MiniMRP will tell you what parts you need, what's missing etc.

But I suppose you might also need to build things using raw materials. Looking at our lawnmower we need a blade. Lets assume the blade is just a strip of metal that needs cutting to the right shape, bending, sharpening and a hole drilling so it can be attached to the bottom of the mower.

You'd create a part number for the blade and make it an assembly (it becomes a sub assembly within the lawnmower assembly)

Blade assembly would have a parts list something like:

Item 1. Strip of Metal 15 inches x 2 inches. Qty 1, Cost $2.
Item 2. Cutting process. Qty 1, Cost $1
Item 3. Sharpening process. Qty 2 (Sharpen 2 edges), Cost 0.50 each)
Item 4. Drilling process. Qty 1, Cost 0.25

Now when you produce the bill of materials to make a lawnmower the total build cost will include all the components and all of the raw materials and all that labor for those machining processes.

When you want to build some lawnmowers it might tell you to buy 75inches of steel. But won't follow that steel through the individual stages of production. It'll just tell you how many nuts and bolts you need to buy and how many blades you need to make so you can complete your customer orders.

Thanks for your explanation. I'm not a big believer in work centers, capacity planning, and other stuff that goes with full-blown MRP. Your solution just might do the trick!
