本文针对运输问题中的线性运输问题,在传统研究的基础上加以时间总量的约束,介绍了研究带有时间约束的运输问题的客观性和必要性,提出了一类带有时间约束的运输问题的数学模型,给出了将时间量转化为成本量的方法,并用算例说明了该模型的求解过程,计算结果符合实际情况。 Aiming at the problem of linear transportation in transportation, this paper puts the restriction of total amount of time on the basis of traditional research, introduces the objectivity and necessity of studying transportation with time constraint, and proposes a kind of transportation with time constraint The mathematical model of the problem is given, and the method to convert the amount of time into the cost is given. An example is given to illustrate the solution of the model. The calculation results are in accordance with the actual situation.
