Logistics Supply Chain Data Analysis Practice: From Transportation Cost to Delivery Efficiency Optimization

Against the backdrop of globalization and rapid e-commerce development, the logistics supply chain industry faces unprecedented challenges: customer requirements for delivery timeliness are increasingly high, transportation costs continue to rise, and inventory management is becoming more complex. Data analysis has become a key tool for logistics enterprises to enhance competitiveness. This article deeply explores data analysis practices in the logistics industry to help enterprises achieve cost reduction and efficiency improvement through data-driven approaches.

Characteristics of Logistics Industry Data Analysis

Diverse and Scattered Data Sources

Logistics enterprise data is scattered across multiple systems:

Transportation Management System (TMS): Records transportation orders, vehicle scheduling, route planning, freight settlement and other data.

Warehouse Management System (WMS): Manages inbound, outbound, inventory, picking, inventory counting and other warehouse operation data.

Order Management System (OMS): Handles customer orders, order status, delivery confirmation and other information.

GPS Positioning System: Real-time tracking of vehicle locations, driving trajectories, dwell times and other data.

Financial System: Records transportation costs, warehouse fees, labor costs, fuel costs and other financial data.

These systems are often provided by different vendors, with inconsistent data formats, forming serious data silos. Comprehensive data analysis requires first breaking through these system barriers.

High Real-time Requirements

Logistics is a highly dynamic industry:

Abnormalities During Transportation: Unexpected situations like vehicle breakdowns, traffic congestion, weather impacts require real-time monitoring and response.

Rapid Inventory Changes: During e-commerce promotions, inventory may change dramatically within hours, requiring real-time awareness of inventory levels.

Delivery Timeliness Commitments: Customer-committed delivery times need real-time tracking to ensure timely delivery.

Traditional T+1 data analysis mode can no longer meet the logistics industry's needs; enterprises require near-real-time or even real-time data analysis capabilities.

Large and Complex Data Volume

Large logistics enterprises generate massive data daily:

Order Data: Daily order volume may reach hundreds of thousands or even millions.

Trajectory Data: Each vehicle generates a GPS positioning record every minute; a fleet of 1,000 vehicles generates over 1 million trajectory records daily.

Operation Data: Every scan, every picking in the warehouse generates a record.

How to quickly find valuable information in massive data is a technical challenge logistics enterprises face.

Typical Data Analysis Scenarios

Scenario 1: Transportation Cost Analysis and Optimization

Transportation cost is the largest cost item for logistics enterprises, typically accounting for over 50% of total costs. Refined cost analysis helps enterprises find cost reduction spaces.

Key Analysis Questions:

"What is the average transportation cost for each route in the past month?" "Which routes have the highest unit costs? What are the reasons?" "Compare cost differences between self-operated vehicles and outsourced vehicles" "What proportion of transportation cost is fuel cost?" "How much impact does empty running rate have on costs?"

Data Analysis Difficulties:

Cost data is scattered across multiple systems, requiring integration of transportation fees, fuel costs, tolls, labor costs and other dimensions.

Cost structures vary greatly across different routes, requiring establishment of standardized cost accounting models.

Impact of external factors (oil price fluctuations, seasonal demand) on costs needs separate analysis.

Optimization Directions:

Route Optimization: Analyze historical transportation data to find optimal routes, reducing transportation distance and time.

Vehicle Utilization Improvement: Analyze vehicle empty running rates and improve load factors through cargo matching optimization.

Transportation Capacity Structure Adjustment: Compare cost-effectiveness of self-operated and outsourced transportation to optimize capacity structure.

Fuel Management: Monitor abnormal fuel consumption and identify non-standard driving behaviors.

Scenario 2: Delivery Timeliness Monitoring and Improvement

Delivery timeliness directly affects customer satisfaction and is a core competitiveness of logistics enterprises.

Key Analysis Questions:

"What is the on-time delivery rate for each region this week?" "Which regions have the worst delivery timeliness?" "What are the main causes of delivery delays?" "What are the differences in delivery efficiency across different time periods?" "How to predict tomorrow's delivery pressure?"

Data Analysis Difficulties:

Delivery timeliness is affected by multiple factors: order volume, delivery distance, traffic conditions, weather, delivery personnel capability, etc.

Need to establish reasonable timeliness standards; different regions and product types have different timeliness requirements.

Identification and attribution of abnormal situations requires combining multi-dimensional data.

Improvement Measures:

Delivery Route Optimization: Dynamically plan optimal delivery routes based on historical data and real-time traffic conditions.

Delivery Personnel Performance Analysis: Identify work patterns of high-efficiency delivery personnel and promote best practices.

Predictive Scheduling: Predict order volumes based on historical data and pre-allocate transportation capacity.

Abnormal Alerting: Real-time monitor delivery progress and provide early warnings and interventions for orders that may be delayed.

Scenario 3: Warehouse Turnover Analysis

Warehouse cost is another major cost item for logistics enterprises; improving inventory turnover rate can significantly reduce warehouse costs and capital occupation.

Key Analysis Questions:

"What is the inventory turnover rate for each warehouse?" "Which products have the lowest turnover rates?" "How much warehouse space do slow-moving goods occupy?" "What are the inventory turnover patterns for different seasons?" "How to optimize inventory structure?"

Data Analysis Difficulties:

Inventory data accuracy depends on the standardization of warehouse operations; data quality varies.

Different products have vastly different turnover characteristics and require classified management.

Inventory optimization needs to balance cost and service levels; simply pursuing low inventory is not acceptable.

Optimization Strategies:

ABC Classification Management: Classify products by turnover rate and value, with differentiated management.

Safety Stock Optimization: Dynamically adjust safety stock levels based on historical sales data and prediction models.

Slow-Moving Product Handling: Regularly identify slow-moving products and accelerate turnover through promotions or transfers.

Warehouse Layout Optimization: Place high-turnover products in locations convenient for picking to improve operation efficiency.

Scenario 4: Vehicle Utilization Analysis

Vehicles are core assets of logistics enterprises; improving vehicle utilization can increase transportation capacity without adding vehicles.

Key Analysis Questions:

"What is the average load factor of the fleet?" "Which vehicles have the lowest utilization?" "What is the empty running rate? How to reduce it?" "What is the average daily mileage of vehicles?" "How to improve effective operating time of vehicles?"

Data Analysis Difficulties:

Vehicle utilization is affected by multiple factors: order distribution, route planning, cargo matching capability, etc.

Need to distinguish between planned empty running (return trips) and unplanned empty running (insufficient cargo matching).

Vehicle maintenance, driver rest and other factors also affect utilization.

Improvement Measures:

Cargo Matching Optimization: Use algorithm optimization for cargo matching plans to improve load factors.

Return Trip Cargo Development: Find cargo for return trip vehicles to reduce empty running rates.

Vehicle Scheduling Optimization: Dynamically schedule vehicles based on order predictions and vehicle locations.

Vehicle Type Structure Optimization: Optimize vehicle type configuration based on cargo characteristics and order scale.

Scenario 5: Customer Service Quality Analysis

Customer satisfaction is the lifeline of logistics enterprises, requiring continuous monitoring and improvement of service quality.

Key Analysis Questions:

"What is the customer complaint rate? What are the main complaint reasons?" "What are the differences in service satisfaction across different customers?" "Which links are most prone to service problems?" "What is the relationship between service quality and customer churn?" "How to predict customer churn risk?"

Data Analysis Difficulties:

Service quality is multi-dimensional, including timeliness, damage rate, service attitude, etc.

Customer feedback data is often unstructured (text reviews) and requires NLP technology for processing.

The causal relationship between service quality and business growth is difficult to quantify.

Improvement Directions:

Complaint Root Cause Analysis: Classify and attribute complaint data for targeted improvement.

Service Standardization: Establish service quality standards and monitoring systems.

Customer Stratified Service: Provide differentiated services for high-value customers.

Predictive Maintenance: Identify early signals of service quality decline for proactive intervention.

Application of Natural Language Queries in Logistics Scenarios

Lowering Data Access Barriers

Data analysis needs in logistics enterprises often come from business departments: operations managers need to monitor delivery timeliness, warehouse supervisors need to analyze inventory turnover, finance departments need to calculate costs. These personnel typically don't have SQL skills and traditionally need to rely on IT departments or data analysts.

Using natural language queries, business personnel can directly ask:

"What is the on-time delivery rate for the East China region this week?" "Compare inventory turnover rates between Shanghai warehouse and Hangzhou warehouse" "Find the 10 routes with the highest transportation costs" "How many orders were delayed more than 2 hours yesterday?"

AI engines automatically understand intent, generate SQL queries, return results and display them with appropriate charts. This transforms data analysis from "waiting for IT support" to "self-service queries," greatly improving response speed.

Supporting Exploratory Analysis

Logistics business is complex and changing; many problems require deep drilling to find root causes. Natural language queries support continuous follow-up questions:

First question: "This week's delivery delay rate is 5% higher than last week, why?" Second question: "Which regions are the delays mainly concentrated in?" Third question: "Is there abnormal growth in order volume for these regions?" Fourth question: "Is the number of delivery personnel sufficient?" Fifth question: "Are any delivery personnel on leave or have quit?"

This exploratory analysis would require pre-configuring numerous reports in traditional BI tools, but natural language queries make analysis flexible and immediate.

Real-time Monitoring and Alerting

Logistics operations require real-time monitoring of key metrics with immediate response to anomalies. Through natural language queries, operations personnel can check anytime:

"How many orders are currently in transit?" "What is today's delivery completion rate?" "Which orders may be delayed?" "Which products currently have inventory alerts?"

Systems can also set up automatic alerting rules to proactively push notifications when metrics are abnormal, allowing managers to grasp the situation at the first moment.

Data-Driven Logistics Optimization Cases

Case: A Regional Logistics Company Reduced Transportation Costs by 15%

Background: This is a regional logistics company covering the East China region, with 500 self-operated vehicles and 200 outsourced vehicles, processing 20,000 orders daily. The company faces mounting pressure from rising transportation costs and hopes to find cost reduction spaces through data analysis.

Analysis Process:

Cost Structure Analysis: Through integrating TMS, financial system, and GPS data, a complete cost accounting model was established. Found that fuel costs account for 40%, labor costs 30%, vehicle depreciation 15%, and other fees 15%.

Route Cost Comparison: Analyzed unit costs of 50 main routes and found that some routes have significantly higher costs than average. After deep analysis, discovered that the empty running rate for these routes is as high as 35%, while the average empty running rate is only 20%.

Vehicle Utilization Analysis: Found that the average load factor for self-operated vehicles is only 65%, while industry benchmark enterprises can reach 80%. The main reason is that the cargo matching algorithm is simple and doesn't fully consider the matching of cargo volume and weight.

Outsourcing Cost Comparison: Compared costs between self-operated and outsourced vehicles and found that for some long-distance routes, outsourced vehicle costs are actually lower because outsourced vehicles can pick up other cargo on return trips.

Optimization Measures:

Cargo Matching Algorithm Upgrade: Introduced an intelligent cargo matching system that comprehensively considers cargo volume, weight, and destination, increasing load factor from 65% to 78%.

Return Trip Cargo Development: Cooperated with other logistics enterprises to find cargo for return trip vehicles, reducing empty running rate from 35% to 22%.

Transportation Capacity Structure Adjustment: Changed some long-distance routes from self-operated to outsourced, concentrating self-operated vehicles on short-distance and high-frequency routes.

Route Optimization: Optimized delivery routes based on historical data and real-time traffic, shortening average driving distance by 8%.

Results:

After 6 months of implementation, transportation costs decreased by 15%, saving 12 million yuan annually. At the same time, delivery timeliness improved, with on-time delivery rate increasing from 92% to 95%.

Case: An E-commerce Logistics Company Improved Warehouse Turnover by 40%

Background: This is a third-party logistics company providing warehouse and distribution services for e-commerce platforms, operating 10 regional warehouses with a total warehouse area of 200,000 square meters. The company found that warehouse costs were rising year by year with serious inventory accumulation.

Analysis Process:

Inventory Turnover Analysis: Calculated inventory turnover rates for each warehouse and found the average turnover rate is only 6 times/year, far below the industry benchmark of 10 times/year.

Product Classification Analysis: Performed ABC classification on 50,000 SKUs and found that 20% of products contribute 80% of outbound volume, but these high-turnover products weren't being given priority processing.

Slow-Moving Product Identification: Found that 15% of products have no outbound records for over 90 days, occupying significant warehouse space.

Warehouse Layout Analysis: Found that high-turnover and low-turnover products were mixed together, causing low picking efficiency.

Optimization Measures:

ABC Classification Management: Classified products into A, B, C categories, with A-category products (high-turnover) occupying the most convenient storage locations and C-category products (low-turnover) placed in remote positions.

Slow-Moving Product Handling: Coordinated with customers to promote, return, or destroy slow-moving products, releasing warehouse space.

Dynamic Inventory Adjustment: Dynamically adjusted inventory levels for each warehouse based on sales forecasting models to avoid overstocking.

Warehouse Layout Optimization: Replanned warehouse layout, concentrating high-turnover products in the picking area to shorten picking paths.

Results:

After implementation, inventory turnover rate increased from 6 times/year to 8.4 times/year, a 40% improvement. Warehouse costs decreased by 20%, and picking efficiency improved by 30%.
