加拿大代写留学生作业:模型中的重要性

当涉及到模型制作时,想象力的程度也很重要。为了传达“目标”,建模者必须很好地定义自己的想象力。这让我们意识到语言在模型中的重要性。如果模型不能很好地用任何一种语言表达,无论是地图中的符号,数学模型中的方程,甚至是人文科学中的流程图,模型都是无效的,会影响对知识的搜索。如果模型被定义为一个方面在世界上的简化表示,那么存在的复杂系统又如何呢?如果模型能帮助我们更好地理解世界的某些方面,那么我们为什么不能模仿人类或动物的行为呢?这些问题不能直接回答,但可以通过对术语模型的狭义定义及其应用的局限性在一定程度上加以解决。如本文所述,模型在自然科学和工程领域有些用处。相反,当涉及到特定的知识领域时,模型就没有任何用处了,例如伦理。这是因为模型不能代表道德状况,而且很难预测人类行为。建立一个模型来帮助解决道德上的是非两难问题是没有意义的。人类的心理是无法逻辑预测的,因此即使存在这样一个模型,它也会产生很多结论,最终模型的“目标”变得模糊。同样的道理也适用于宗教,因为整个知识领域都建立在已经存在的信仰和“事实”的基础上——不需要模型来预测;未来已经决定了。因此,模型对知识搜索的帮助和阻碍在很大程度上取决于知识的范围。

The degree of imagination is also important when it comes to model making. A modeller has to define his imagination well in order to convey the ‘objective’. This leads us to the importance of language in a model. If the model is not expressed well in any kind of language, be it symbols in maps, equations in mathematical models or even flow diagrams in human sciences, the model is not effective and can affect the search for knowledge.If models are defined as simplified representations of an aspect in the world, then what about complex systems that exist and yet cannot be put into simplified representations with a valuable objective? If models help us in better understanding of certain aspects of the world, then why can we not model human or animal behaviour? These questions cannot be directly answered but they can be resolved to some extent by expressing a narrowed definition of the term model and its limitation of application.Models are somewhat useful in areas of natural sciences and engineering as mentioned in this essay. Conversely, models are not whatsoever useful when it comes to certain areas of knowledge, for example ethics. This is because a model cannot represent moralistic situations and it is difficult to predict human behaviour. To create a model that would help resolve an ethical dilemma of what is right or wrong simply does not make sense. Human psychology cannot be predicted logically and therefore even if such a model existed it would create many conclusions and in the end the ‘objective’ of the model becomes vague. The same applies to religion where the entire area of knowledge is based on beliefs and ‘facts’ that already exist – there is no need of models for prediction; the future has already been decided. Therefore whether models help or hinder the search for knowledge significantly depends on the area of knowledge.
