ABSTRACT

Generic simulation models are designed to enable model reuse. We argue that there are two weaknesses within the generic simulation modelling literature. Firstly, that generic models sacrifice the relative simplicity of a bespoke simulation model for flexibility. Secondly, that generic models are published in conceptual form only. If researchers cannot access computer implementation of models, then there is little incentive or benefit to recode one over coding a simpler bespoke simulation model. We introduce an incremental approach to generic modelling in discrete-event simulation. We develop an archetype setting-specific generic model of a hospital ward. The archetype model is first developed and applied in a rehabilitation ward setting. Then a second team applies the model in a specialised intensive care setting. We report the successes, obstacles and redevelopment needed for reuse of the generic model along with how the results of these studies were used to inform healthcare delivery.

摘要

通用仿真模型旨在实现模型重用。我们认为通用模拟建模文献中存在两个弱点。首先，通用模型为了灵活性而牺牲了定制模拟模型的相对简单性。其次，通用模型仅以概念形式发布。如果研究人员无法访问模型的计算机实现，则与对简单的定制模拟模型进行编码相比，重新编码模型的动机或收益很小。我们为离散事件仿真中的通用建模引入了一种增量方法。我们开发了医院病房的原型设置特定的通用模型。原型模型首先被开发并应用于康复病房。然后，第二个团队在专门的重症监护环境中应用该模型。我们报告成功，
