Facility Layout Planning with SHELL and Fuzzy AHP Method Based on Human Reliability for Operating Theatre.

Area of Science:

• Industrial Engineering
• Healthcare Management
• Operations Research

Background:

• Effective facility layout planning is crucial for reducing operational costs in manufacturing and service industries.
• Operating theatre design significantly impacts efficiency, safety, and patient outcomes.
• Existing methods often overlook human factors and reliability in complex healthcare environments.

Purpose of the Study:

• To propose a new evaluation approach for optimizing operating theatre facility layout design.
• To integrate fuzzy analytic hierarchy process (FAHP) and human reliability analysis (HRA) for layout optimization.
• To enhance safety, security, and reliability in operating theatre design.

Main Methods:

• Systematic layout planning (SLP) was employed to design initial layout schemes based on field investigations.
• A criteria system was developed using human reliability analysis, considering software, hardware, environment, and liveware.
• Fuzzy analytic hierarchy process (FAHP) was utilized as a multicriteria decision-making technique to evaluate and compare layout schemes.

Main Results:

• The study identified key properties of facility layout planning specifically for hospital operating theatres.
• The proposed integrated approach effectively evaluates layout schemes based on defined criteria.
• Results highlight the importance of considering human factors and reliability in layout decisions.

Conclusions:

• Selecting an optimal operating theatre layout requires balancing system strategies and goals with safety, security, and reliability.
• The integrated FAHP and HRA approach offers a robust method for facility layout optimization in healthcare settings.
• Improved facility layout design contributes to enhanced operational efficiency and patient safety.
