The Initial Analysis about Freight Cost Fields of the Globe

The freight cost fields of the globe own basic conceptions themselves. The classifications of freight cost fields of the globe include: basic freight cost field, freight and incidental cost field, sectional sphere curve integral field, non-sphere field, branch sphere curve integral field, condition sphere curve integral field, inverse sphere curve integral field, etc. Every sort of the fields possesses special intension. There are many features of freight cost fields of the globe, such as the existence of anti-gradient directions, the angle “continuous” and “angle interruption” character, the dynamic character, the character of existing many influence factors, branch one-way character, the character of market profit trending towards average level, etc. Freight cost field sphere curve integral errors include mainly: the errors caused by the transform of the integrated functions and projective relationship, the errors caused by the imitating the integrated functions from original data, the errors caused by the courses of finding the original functions of the integrations and choosing parameter variables, etc. The spread conceptions of freight cost fields include mainly: time field, cargo load field, risk probability field, etc. The applying objects of the conceptions of freight cost fields of the globe and sphere curve integrals include mainly: investing and policy navigation, to judge the competitive power of carriers and traffic modes, to construct more harmonious competitive environment, etc. The thought of freight cost fields of the globe is a research direction concealing gigantic value.
