求翻译：（5） 中心进货固定成本增大通过平摊分配到每个配送周期，因此引起系统平均总成本增大（算例16-19）；中心进货的大型车辆装载能力增大时（算例20-21），并没有给总成本及FP-IRH策略的效率造成很大的影响，表明中心进货运输条件达到一定水平时，系统平均总成本主要取决于中心库存成本及给零售商的配送成本。是什么意思？

(5) The center purchase fixed costs increase by equal shares allocated to each distribution cycle, thus causing the average total cost increases (examples 16-19); center purchase of large vehicles loading capacity increases (for example 20 - 21), and did not give the total cost and the fp-irh the ef

(5) Center purchase fixed cost increases by split distribution to each distribution cycle, so caused system average total cost increases (is cases 16-19); Center purchase of large vehicles mount ability increases Shi (is cases 20-21), and no to total cost and the FP-IRH policy of efficiency caused i
