Simulation-Based Optimization for Improving Hospital Performance

Capacity planning in the hospital queueing network with blocking: simulation-based optimization approach

Introduction: Hospital administrators have always faced the challenge of providing the best possible health services in a resource-limited environment. The patient flow throughout the hospital is affected by lack of the capacities that can lead to bed-blocking among the hospital units. In this research, the patient flow in the hospital is modeled as an open queueing network with blocking. Then,...

A Simulation Model for Optimization of the Internal Handling Fleet Size at Shahid Rajaee Container Port Based on Performance Evaluation

The dramatic increasing of sea-freight container transportations and the developing trend for using containers in the multimodal handling systems through the sea, rail, road and land in the present market cause some challenges to the general managers of container terminals such as increasing demand, competitive situation, new investments and expansion of new activities and the need to use new m...

OPTIMIZATION-BASED MONITORING-SUPPORTED CALIBRATION OF A THERMAL PERFORMANCE SIMULATION MODEL

Building performance simulation is being increasingly deployed beyond the building design phase to support efficient building operation. Specifically, the predictive feature of the simulation-assisted building systems control strategy provides distinct advantages in view of building systems with high latency and inertia. Such advantages can be exploited only if model predictions can be relied u...

Model enhancement: Improving theoretical optimization with simulation

When using optimization techniques based on mathematical models, we often need to make important simplifications. The solution thus provided, even if proven to be theoretically one of the best, might not be so good in practice. Simulation can be used to evaluate the actual performance of the solution. We propose here a coupling between optimization and simulation that tries to improve the solut...

Simulation Optimization: Improving decisions under uncertainty

Ergonomics and simulation-based approach in improving facility layout

The use of the simulation-based technique in facility layout has been a choice in the industry due to its convenience and efficient generation of results. Nevertheless, the solutions generated are not capable of addressing delays due to worker’s health and safety which significantly impact overall operational efficiency. It is, therefore, critical to incorporate ergonomics in facility design. I...
