Exploring the Process of Model Formulation

数学模型对于商业和政府的日常运作已经变得很重要。模型有助于规划、评估、管理和运行所有类型的系统。随着个人电脑的普及，更多的型号将被使用。由..开发。更多的人。然而，尽管社会对模型的依赖程度越来越高，但无论是在实践中还是在教育中，我们都没有对模型的形成过程给予足够的重视。模型公式化是建模过程的第一步：从模糊的“问题”感觉转移到可以操作以产生解决方案的形式表示。改进的、系统的模型制定方法对“建模科学”的发展非常重要，这将提高建模工作的效率和效力。这项研究的目的是：(1)描述公认专家实践的模型制定过程；(2)发展判断模型制定成功的方法；(3)提出改进的模型制定程序。这项研究将是探索性的，应该为关于有效模型制定的可实验验证的命题铺平道路。它还应该导致改进培训模特儿的技术和材料

Mathematical models have become important to the routine functioning of commerce and government. Models help with planning, evaluating, managing and operating systems of all types. With the spread of personal computers, more models will be used by .. and developed by .. more people. Yet, even as society becomes more dependent on models, we have not given enough attention to the process of model formulation, either in practice or in education. Model formulation is the first step in the modeling process: moving from a vague sense of "problem" to a formal representation that can be manipulated to yield solutions. Improved, systematic methods of model formulation are important to the development of "modeling science" that will improve the efficiency and effectiveness of modeling efforts. The objectives of this research are to: (1) Describe the model formulation process as practiced by acknowledged experts; (2) Develop ways to judge the success of model formulation; (3) Suggest improved procedures for model formulation. This research will be exploratory, and should pave the way for experimentally verifiable propositions about effective model formulation. It should also lead to improved techniques and materials for educating modelers
