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

数学模型对于商业和政府的日常运作变得非常重要。 模型有助于规划、评估、管理和操作系统所有类型。 随着个人计算机的普及，更多的模型将被..更多的人使用并被..更多的人开发。 然而，即使社会变得更加依赖模型，我们仍然没有对模型制定的过程给予足够的重视，无论是在实践中还是在教育中。 模型制定是建模过程的第一步：从模糊的“问题”意识转变为可以操纵以产生解决方案的正式表示。 改进的、系统的模型制定方法对于“建模科学”的发展非常重要，这将提高建模工作的效率和有效性。 本研究的目标是： (1) 描述公认专家实践的模型制定过程； (2) 制定判断模型制定是否成功的方法； (3)提出模型制定的改进程序。 这项研究将是探索性的，并且应该为关于有效模型制定的可实验验证的命题铺平道路。 它还应该改进用于教育建模者的技术和材料
