چگونه می توان تصمیم گیرندگان را در بهبود بخش اورژانس حمایت کرد؟ شبیه سازی، بهینه سازی و روش داده کاوی

The improvement of emergency department processes involves the need to take into consideration multiple variables and objectives in a highly dynamic and unpredictable environment, which makes the decision-making task extremely challenging. The use of different methodologies and tools to support the decision-making process is therefore a key issue. This article presents a novel approach in healthcare in which Discrete Event Simulation, Simulation-Based Multi-Objective Optimization and Data Mining techniques are used in combination. This methodology has been applied for a system improvement analysis in a Swedish emergency department. As a result of the project, the decision makers were provided with a range of nearly optimal solutions and design rules which reduce considerably the length of stay and waiting times for emergency department patients. These solutions include the optimal number of resources and the required level of improvement in key processes. The article presents and discusses the benefits achieved by applying this methodology, which has proven to be remarkably valuable for decision-making support, with regard to complex healthcare system design and improvement.
