Strategies to Reduce Truck Driver Turnover.
Dr. David Correll discusses interventions to reduce turnover and prevent outcomes.
Audience interest in machine learning applications and technology in the supply chain is revealed in a poll.
Dr. Correll aims to address these topics during the webinar.
The webinar emphasizes audience interaction with prepared questions and encourages participants to ask questions using the Q&A feature.
Impact of truck driver shortage on global supply chains.
Reports of shortages causing delivery delays and impacting American supply chains.
Projections suggest shortage could double in the next decade.
Efforts to address shortage include diversifying demographics of truck drivers.
Lack of truck drivers poses pressing challenges for modern supply chains, requiring intervention to prevent further worsening of the situation.
Global shortage of truck drivers.
Unfilled positions in Mexico, Argentina, Europe, former Soviet Union, and China.
High turnover rate in the United States.
Introduction of electronic logging devices (ELD) for truck drivers.
ELDs track hours of service and driving time to monitor compliance with regulations and improve safety.
Analysis of electronic logging device data for truck drivers revealed they drive an average of six and a half hours per day.
Despite being legally allowed to drive for 11 hours, this raises questions about driver shortage and underutilization.
The data shows the issue lies in drivers not working all possible hours, leading to industry inefficiencies.
Findings suggest a need to address discrepancies and improve utilization of available resources.
This is crucial in effectively tackling the driver shortage in the industry.
The speaker challenges the notion of a driver shortage in the trucking industry.
Increasing driving time for existing drivers by just 18-20 minutes a day can alleviate the perceived shortage.
Machine learning analysis revealed that better utilization of drivers is key to retention.
The study involved collecting data from drivers' electronic logging devices.
Utilizing available data is important for optimizing driver efficiency.
Driver retention patterns analyzed through hours worked per week.
Drivers who stayed with the company worked significantly more hours than those who left.
Drivers who worked more on Mondays through Fridays were more likely to stay.
Data cleaning and filtering resulted in a sample of 1298 drivers for study.
Importance of utilizing tools like Python and Pandas for data analysis highlighted.
Data cleaning and feature engineering are crucial steps in preparing data for machine learning in supply chain analysis.
It is essential to split the data into training and test sets, with an 80/20 ratio being commonly recommended.
Three classification algorithms - logistic regression, random forest, and support vector machine - are utilized to forecast driver behavior.
Each algorithm possesses distinct traits and parameters that can be adjusted for improved accuracy.
The video underscores the technical intricacies of these algorithms and the necessity of expertise in machine learning for optimal tuning.
Importance of tuning hyperparameters in machine learning algorithms.
Dividing data into training and test sets is crucial for experimenting with hyperparameters.
Evaluating classifier performance using a confusion matrix and measures like accuracy and sensitivity is essential.
Sensitivity is crucial for disease prediction to avoid missing true positives.
Accuracy and sensitivity results for logistic regression, random forest, and support vector machine experiments were showcased.
Model accuracy and sensitivity evaluation.
The model showed mid-60s to almost 70% accuracy and around 50% sensitivity, deemed sufficient for publication despite desiring higher scores.
Introduction of ROC curve to evaluate prediction quality, with performance slightly better than random and similar classifier performance in cross-validation.
Logistic regression, random forest, and support vector machine had a 65% accuracy in the study.
Shapley values are emphasized as a tool to understand feature contributions to model output, revealing complex interactions between features.
Shapley values used to create a waterfall plot showing important features in predicting outcomes.
Different key features identified for each algorithm, indicating complexity in driver turnover prediction.
Machine learning applied to driver work logs successfully identifies at-risk drivers for intervention.
Keeping drivers active and moving is crucial for retention, as sitting still increases turnover.
ELD tool, initially a regulatory burden, proved valuable in predicting turnover and identifying supply chain issues.
Misdiagnosis of truck driver shortage.
The shortage is attributed to a utilization crisis where drivers' time is wasted.
