How It Works
The Problem
Most facilities determine spare parts inventory through vendor recommendations or experience. This leads to two expensive outcomes: stockouts that trigger emergency procurement at 6-8x standard shipping costs, or overstocked shelves tying up capital in parts that expire unused. MRO holding costs alone run 20-30% of inventory value annually.
The Approach
SpareMind uses a statistical model that accounts for your fleet size, failure rates, procurement lead times, part criticality, system redundancy, shelf life, and cost impact to calculate recommended stocking quantities.
Where you don't provide data (cost, lead time, criticality, failure rate), the system estimates values based on part type and manufacturer. You can always override any estimate with your own numbers.

Criticality Guide
When entering parts below, assign a criticality level – or leave it on "Auto" and the system will estimate it from the part description.
Critical
Equipment stops without this part. No workaround. Examples: compressors, PLCs, control boards, VFDs, protective relays, hydraulic pumps.
Essential
Equipment runs in degraded mode or a manual workaround exists. Examples: sensors, fans, contactors, breakers, communication modules.
Desirable
Readily available or non-essential. No immediate operational impact. Examples: filters, gaskets, fuses, terminals, labels, lubricants.
Parts List
Add up to 5 parts. The more detail you provide, the better the estimates.

Works for Any Industry
If you have equipment with parts that fail, SpareMind calculates how many spares to keep on hand.
Semiconductor Fabs
Fab tools with thousands of parts per system. Downtime costs $1M+/day.
Mining Operations
Haul trucks, crushers, conveyors. $180K per breakdown incident.
Oil & Gas Facilities
200,000+ SKUs across platforms. Hundreds of thousands per day offline.
Data Centers
UPS, cooling, power distribution. 54% of outages cost over $100K.
Water & Utility Operations
Pumps, motors, SCADA. Aging infrastructure with run-to-failure mindset.
Telecom Networks
Millions of network components. SLA penalties from parts shortages.
Manufacturing Plants
Production lines, PLCs, VFDs, motors. Every minute of downtime costs.
Pharmaceutical Facilities
Clean rooms, HVAC, process controls. Compliance demands uptime.
