Mining

Supply for mining operations

nudu connects maintenance requirements with available stock and purchase orders to resolve supply exceptions.

Material availability before maintenance

A part recorded in stock may already be reserved. A supplier’s revised date can leave a maintenance order without the required material.

Applications across mining procurement

These applications are configured for each operation. Availability depends on accessible data and approved integrations.

Critical spares

Stock available for maintenance. nudu compares work order requirements with unreserved stock and pending purchase orders to identify shortages before the required date.

Case record. Missing item linked to the work order, with its required date and responsible team.

Supplier confirmations

Agreed dates and quantities. nudu requests missing confirmations and flags differences against the purchase order for procurement review.

Case record. Supplier response attached to the order and any deviation assigned for resolution.

Replenishment requests

Thresholds by material and site. nudu identifies stock below the approved minimum and prepares a requisition using existing procurement rules.

Case record. A proposed requisition with supporting stock data, subject to purchasing approval.

Receipt and invoice discrepancies

Evidence for invoice review. nudu compares the invoice with the purchase order and recorded receipt, then requests clarification when quantities or prices differ.

Case record. A documented discrepancy for accounts payable, with no automatic payment release.

Illustrative example

A bearing required for scheduled maintenance

  1. 01

    Requirement

    A maintenance order requires two bearings. One unreserved unit is recorded in stock.

  2. 02

    Investigation

    nudu finds a pending purchase order and requests confirmation of the available quantity and date.

  3. 03

    Approval

    The proposed date falls after the maintenance window. Procurement receives the discrepancy; engineering approves any substitute.

  4. 04

    Record

    The approved response is linked to the original requirement. The case remains open until the supply exception is resolved.

Implementation

An initial, defined scope

Required data
The initial scope uses a material catalogue with criticality and stock by site, including reservations. Open purchase orders and dated maintenance requirements complete the comparison.
Approval rules
Material substitution requires engineering approval. New orders and changes to maintenance dates follow the operation’s authorisation rules. The pilot starts in observation mode.

Pilot evaluation

  • Requirements without confirmed material
  • Time to obtain supplier confirmation
  • Age of unresolved purchasing discrepancies
  • Requisitions approved without correction

The pilot compares these measures with the operation’s baseline. Targets are agreed after the initial assessment.
