Prosthetic Cost-Reduction Simulator

Prosthetic Cost-Reduction Simulator

A practical, browser-only estimator for in-house vs outsourcing unit cost, lead time, and a weighted recommendation. No external libraries. For planning and decision support only.

Language

Quick start

1. Click a preset to load example values
2. Adjust batch size, scrap rate, material, wage, machine rate
3. Add BOM line-items to reflect real materials
4. Tune setup/cycle and machine-share per process step
5. Adjust weights (cost/quality/lead time) then “Recompute recommendation”
6. Click “Calculate” to refresh results

Production basics

Batch quantity Target scrap rate (%) Material waste (%) Overhead rate (%) Learning curve (%) Lead-time target (days) Outsourcing unit price (KRW/EA) Outsourcing lead time (days) Outsourcing scrap rate (%) Delivery penalty (KRW/day) Rush surcharge (%) Enable rush mode Material selection Carbon Glass Nylon

 

Base unit cost inputs

Material price (KRW/kg) Material usage (kg/EA) Labor rate (KRW/hour) Machine rate (KRW/hour) Tooling (KRW, one-time) Tooling amortization qty (EA)

BOM material line-items

Item	Qty (kg/EA)	Unit (KRW/kg)	Note	Delete

If BOM is empty, the calculator uses the base material price and usage from the inputs above.

Process steps (time & cost share)

Layup

Setup (hr/batch) Cycle (hr/EA) Machine share (0–1)

Cure

Setup (hr/batch) Cycle (hr/EA) Machine share (0–1)

Machining

Setup (hr/batch) Cycle (hr/EA) Machine share (0–1)

Assembly

Setup (hr/batch) Cycle (hr/EA) Machine share (0–1)

Decision weights (auto-normalized)

Cost weight 50 Quality weight 30 Lead-time weight 20

Outsourcing quality score (1–5)

Lower is better for cost/lead time; higher is better for quality. Two options (in-house vs outsource) are compared and scored.
