Mixed Shop Modeler
Machines, parts, and routings for a high-mix or repair shop: find the constraint before the floor does.
Best for: Resource load in a high-mix or repair shop: many parts or work order types, routings and setups across shared machines, test stands, and bays.
1 / 4Setup: machines with their load, and the overloaded one called out.
Not Sure This Is the One?
What It Does
Lay out machines by floor, route every part through them, and set demand by part and program. The model loads each machine with demand and setup, shows utilization and which parts fall short, and lets you test shifts, machine counts, and demand mix. Works the same for a repair shop where many work order types share test stands and bays. Runs offline from one file.
Machines and floors
Quantity, shifts, hours, setup, operators, and batch processing per machine, laid out by floor.
Part routings
Each part routes through machines with its own processing time and variation.
Demand by part and program
Day, week, month, or year demand, with program-level multipliers for what-if.
Utilization and shortfall
Load per machine including setup, and which parts miss demand and why.
Schedules
Output and production schedules, time-phased.
Sample shop
A generic 13-machine, 38-part shop to learn on before you build your own.
Save to files
Shops save as .spshop files. Nothing is uploaded.
