Inventory Risk Analysis: 460 Hydraulic Room

How daily stock tracking reveals hidden delay, cost, and safety exposure
Reporting Period: 10 February 2025 — 31 January 2026 (11 months)

The Short Version

LYIT tracked daily stock levels for 187 parts in one hydraulic room over 11 months. During that time, parts came close to running out 408 times. Each of those near-misses is a moment where, without a restock, the workshop would have been waiting on a part instead of turning wrenches.

We don't claim all 408 caused downtime — most were caught in time. But the pattern shows a real gap between how fast parts get used and how fast they get replaced. When you model even a conservative slice of those events as breakdowns, the potential cost exposure runs into the millions.

This page lets you adjust the assumptions yourself and see what the numbers look like for your operation.

Roads between terminals and surface stores carry regular heavy-vehicle traffic. HV/LV interaction is a recognised risk area. Every retrieval trip adds exposure. These figures are modelled estimates.
What's a Zero Point?
Plain-language explanation of the core metric
1

Stock gets used

Parts are consumed during planned maintenance and breakdowns. LYIT photographs bin levels daily and tracks the count.

2

Stock approaches zero

When the consumption pattern shows a part heading to zero, that's a Zero Point — a near stock-out. LYIT fires a low-stock alert before it hits zero.

3

The risk window

Each Zero Point is a window where, if a breakdown happened, there's no part on hand. Someone has to drive to surface stores, find the part, and bring it back. That's delay, cost, and road exposure.

Parts That Ran Dry
23 parts recorded zero stock for 7 or more consecutive days — meaning the workshop didn't have them available when needed
Part Number Days at Zero Times It Happened Total Used Restocks Suggested Min Stock Severity
Only zero-stock periods of 7+ consecutive days shown. Suggested minimum stock is based on average consumption scaled to a 4-month lead time with a 1.5x safety factor. Terminal usage only — site-wide consumption should also be considered.
