Cold Chain Pre-Cooling Network Optimization Model for Shandong Province, China

A 2026 study by Chen Ying proposes an integrated optimization framework for designing first-mile pre-cooling distribution center networks for fresh agricultural products. The work includes a multi-objective nonlinear mathematical model minimizing logistics cost and maximizing product freshness, with an empirical case study in Shandong Province, China. The dataset likely contains the model parameters and results from three tested scenarios: no pre-cooling, decentralized pre-cooling, and centralized pre-cooling.

Use Cases

• Evaluating centralized vs. decentralized pre-cooling strategies based on the described cost and freshness trade-offs.
• Calibrating stage-specific freshness decay functions for perishable products based on the model's nonlinear deterioration parameters.
• Analyzing the environmental impact of cold chain logistics based on the incorporated transportation-related carbon emissions.
• Applying genetic algorithms to solve complex location-routing problems in supply chain network design based on the described methodology.

Strengths

• Model results include specific performance metrics: a 3.79% reduction in total daily cost for the centralized strategy compared to a no-pre-cooling baseline.
• The empirical case study provides a concrete geographic focus on Shandong Province, China.
• The framework incorporates multiple objectives: minimizing logistics cost, maximizing product freshness, and accounting for carbon emissions.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale empirical analysis.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (5.5 KB), suggesting it contains model parameters or summary results rather than extensive operational data.
