Hybrid Warehousing Boosts Spare Part Availability by 11.5% While Eliminating Supply Emissions

Integrating digital warehousing with on-demand manufacturing in a hybrid model can significantly enhance spare part availability and eliminate environmental impact from global supply chains.

Applied System Innovation · 2025

Key Findings

01Digital warehousing alone reduced global spare parts supply emissions to zero but decreased availability by 15.1%.
02A hybrid warehouse scenario increased availability by 11.5% while completely eliminating global supply emissions.
03Digital warehousing is effective in reducing stock, simplifying inventory management, and enhancing supply chain greenness and resilience, especially when demand rates are considered.

Application

Design takeaway

When designing for products requiring spare parts, integrate digital warehousing and on-demand manufacturing capabilities to create a more sustainable and resilient supply chain.

How to apply

When specifying spare parts for a new product, model the supply chain using simulation to compare the performance of purely digital, purely physical, and hybrid warehousing strategies.

Project actions

01Consider the environmental impact of your product's entire lifecycle, including maintenance and repair.
02Use simulation to test different spare parts management strategies for your design project.

Method & Evidence

AimTo develop a generic estimation model for spare parts engineers to determine optimal supply and inventory specifications, considering digital warehouses and on-demand manufacturing.

MethodSimulation modeling

ProcedureA case asset was selected, and four spare part management concepts were studied using simulation modeling to evaluate the trade-offs between digital warehouses, on-demand manufacturing, and traditional inventory management.

ContextSpare parts management for hybrid warehousing and on-demand manufacturing.

Variables

IV["Spare part management strategy (digital warehouse, hybrid warehouse, traditional)","Demand rate"]

DV["Spare part availability (%)","Emissions related to global spare parts supply (e.g., CO2 equivalent)"]

CV["Case asset","Simulation modeling parameters"]

Strengths & Limitations

Strengths

+Utilizes simulation modeling for quantitative analysis.
+Addresses a relevant and timely issue of sustainability in product support.

Limitations

The specific case asset and demand rates used in the simulation might not perfectly represent all products or industries.

Reliability & validity

The study's validity relies on the accuracy of the simulation model and the representativeness of the case asset. Reliability would be enhanced by repeating the simulations with varied parameters and potentially comparing results with real-world data if available.

Think critically

How might the cost of on-demand manufacturing equipment and digital infrastructure influence the adoption of these hybrid models in different market segments?

Design Principles

"Optimize spare parts logistics by integrating digital inventory and on-demand production to achieve both high availability and zero supply chain emissions."

This research offers a practical framework for optimizing spare part management by balancing inventory availability with environmental sustainability. It provides actionable insights for designers and engineers to reduce waste and emissions associated with product lifecycle support.

What This Means for Your Design

Using digital copies of spare parts and making them on demand can make things more eco-friendly, but sometimes you might not have the part right away. A mix of digital and physical storage works best to keep things available and green.

How to use in your project

1.Reference this study when discussing the environmental impact of spare parts logistics in your design project.
2.Use the findings to justify the selection of a hybrid warehousing approach for your product's support strategy.
