求翻译：（4） 若配送车辆启动成本很大时（算例编号14-15，从800增大到1600），系统平均总成本增大明显；同时，FP-IRH策略的效率有所提高，说明配送成本相对库存成本很大时，分区整合带来的总成本节约效果更好是什么意思？

(4) If the start-up costs of delivery vehicles (example No. 14-15, increased from 800 to 1600), the average total cost increases significantly; fp-irh strategy efficiency improved, indicating that the distribution costs relative inventory costs, partition integration brought the total cost savings b

(4) * if the vehicle start-up costs are very large (Case Number 14-15, increasing from 800 to 1600) and an average total cost increases, and at the same time obvious FP IRH policy - increased efficiency in the distribution costs, inventory costs are relatively large, and the partition when consolida

(4) When allocates and dispatches the vehicles to start the cost is very big (example serial number 14-15, from 800 increases to 1600), the system average total cost increases obviously; At the same time, the FP-IRH strategy efficiency has the enhancement, explained when the allocation cost relative

(4) if the vehicle when large startup costs (example number 14-15, increased from 800 to 1600), average total costs increase significantly, while increasing efficiency in FP-IRH strategy, description and distribution cost and relative cost of inventory is large, partitioning better total cost saving
