This study introduces a rule-based system for nurse scheduling, addressing both initial formulation and real-time adjustments. The system matches human scheduler performance in dynamic environments.

Area of Science:

  • Operations Research
  • Healthcare Management
  • Artificial Intelligence

Background:

  • Effective personnel scheduling is critical in healthcare to ensure adequate staffing and patient care.
  • Dynamic changes in patient demand and staff availability pose significant challenges to traditional scheduling methods.
  • Existing scheduling systems often lack the flexibility to adapt to real-time operational fluctuations.

Purpose of the Study:

  • To develop and evaluate a novel rule-based, hierarchical system for dual sequential problems: personnel schedule formulation and execution.
  • To address the dynamic nature of healthcare environments by enabling real-time schedule adjustments.
  • To assess the performance of the developed system against human schedulers in terms of key quality metrics.

Main Methods:

Related Experiment Videos

  • A rule-based, hierarchical system was developed to model and solve both schedule formulation and execution problems.
  • The system was applied to the specific context of nurse scheduling and staffing.
  • A double-blind evaluation was conducted to compare the system's schedules with those created by human schedulers.

Main Results:

  • The developed system effectively handles both the initial creation and dynamic adjustment of personnel schedules.
  • Evaluation results indicate the system's schedules are comparable to those produced by human schedulers for units experiencing personnel changes.
  • Key schedule quality metrics, including maintainability, coverage, and personal satisfaction, were assessed.

Conclusions:

  • The proposed rule-based hierarchical system offers a viable solution for complex personnel scheduling in dynamic environments.
  • The system demonstrates comparable performance to human schedulers, suggesting its potential for practical implementation in healthcare settings.
  • This approach provides a robust framework for optimizing nurse staffing and improving overall operational efficiency.
