As hicks income concept did not specify what is called "equal wealth", and thus the income concept formed the basis of many debates concept, and the theory of accounting earnings, especially the capital preservation theory has a great influence. In accounting, people used to call "maintaining the same level of affluence" as capital preservation. This week's sell-off coincided with his prediction. Competition refers to the economic subject in order to maintain and expand their own interests and take all sorts of behavior, the behavior of self-protection and expansion efforts in product quality, price and service advantages, varieties, etc. In November 2017, Advisor Perspectives published an article said that in addition to the improvement of fuel efficiency, petrol consumption decline is due in large part to the following factors: the ageing staff away from the workplace; The home office model is developing more and more; Social media takes the place of face-to-face communication, and travel is unnecessary. More and more young people are no longer driving their cars. And urban population growth accelerated, reducing per capita gasoline dependence. Loading is the work load that is allocated to a work centre. For example, time might be lost while changing over from making one ingredient of another. If the machine in time breaks down, it will not be available. If there is machine reliability data available, this also needs to be taken into account. Sometimes the equipment could possibly be awaiting parts to reach or be 'idling' for a few other reason. Other losses could include an allowance for the device being run below its optimum speed as well as an allowance for that 'quality losses' or defects which the machine may produce. Of course, many of these losses must be small or non-existent in a well-managed operation. Finite loading is definitely an approach which only allocates work to a work up to and including set limit. This limit will be the estimate of capacity to the work centre (based on the times designed for loading). Infinite loading is surely an method of loading work which does not limit accepting work, but rather tries to cope with it. We should improve the market supervision system of administrative law enforcement, industry self-discipline, public opinion supervision and mass participation.
