Optimizing Dairy Product Returns Reduces Total Costs by 9.5%

Implementing a closed-loop supply chain model that accounts for uncertain product return rates can significantly decrease operational costs in the dairy industry.

Journal of industrial and systems engineering. · 2015

Key Findings

01A 9.5% decrease in total supply chain costs was achieved compared to the current operational status.
02The model effectively managed uncertainty in product return rates for products like yogurt.
03The optimized model provided insights for decisions on material sourcing, production, distribution, and recovery.

Application

Design takeaway

Integrate product return and recovery strategies into the core design and operational planning of supply chains to unlock cost savings and improve resource efficiency.

How to apply

When designing new products or optimizing existing supply chains, develop models that account for potential product returns and explore strategies for their reintegration into the production or recovery process.

Project actions

01Consider the end-of-life or return phase of your product as part of the design process.
02Investigate how materials or components can be reused or recycled to reduce waste and cost.

Method & Evidence

AimTo develop and implement a model for optimizing a multi-product, multi-period closed-loop supply chain for a dairy company, specifically addressing uncertainty in product return rates to minimize total costs.

MethodMathematical Modelling (Linear Programming with Chance Constraints)

ProcedureA linear programming model was developed to represent the dairy company's supply chain, incorporating raw material suppliers, manufacturers, distributors, and a recycling center. The model considered uncertain product return rates and aimed to optimize decisions regarding material provision, production, distribution, and product recovery. The model was then implemented using Lingo software with real company data.

ContextDairy industry supply chain management

Variables

IVProduct return rate (uncertainty)

DVTotal supply chain cost

CVNumber of products, time periods, supply chain network structure (suppliers, manufacturers, distributors, recycle center)

Strengths & Limitations

Strengths

+Addresses a practical problem with significant economic implications.
+Uses a quantitative modelling approach to provide specific results.
+Includes a case study for real-world application.

Limitations

It's difficult to get exact data on return rates, and setting up a full closed-loop system can be expensive and complex.

Reliability & validity

The study's validity relies on the accuracy of the linear programming model and the real data used from the case study. Reliability would depend on the reproducibility of the model's results if applied to similar datasets.

Think critically

How might the 'uncertainty' in return rates be further quantified or reduced through design interventions or consumer engagement strategies?

Design Principles

"Design for Circularity: Incorporate mechanisms for product return, refurbishment, and material recovery to minimize waste and maximize resource value throughout the product lifecycle."

This research demonstrates the financial benefits of proactively managing product returns and integrating them back into the production cycle. For design practitioners, it highlights the importance of considering the entire product lifecycle, including end-of-life and return logistics, to achieve greater economic and environmental efficiency.

What This Means for Your Design

This study shows that if a dairy company plans better for products that get returned (like yogurt that's about to expire), they can save a lot of money.
