This article describes the main production processes at forest industry enterprises. The container has free space for the process of goods delivery, which enables customs inspection with partial unloading of goods. This enables to have enough time to inspect the container. It is believed that the costs associated with carriers are increasing. The ratio of free and occupied space when loading a container is not obvious. Two approaches to process modeling have been considered. The methods and algorithms for transport processes simulating have been presented. A solution to the problems of optimal container loading during customs control has been proposed. A simulation model of roundwood transportation across the borders has been implemented, which enables to determine the optimal loading volume of containers in order to minimize the time for customs clearance. The proposed option of partial loading reduces the time of customs inspection, which significantly reduces the costs associated with transportation of timber products, as well as the risk of customer refusal from the products delivered out of schedule.

本文介绍了林业企业的主要生产流程。集装箱在货物交付过程中具有自由空间，可以在部分卸货的情况下进行海关检查。这使得有足够的时间来检查容器。据信，与运营商相关的成本正在增加。装载集装箱时的空闲空间和占用空间的比例并不明显。已经考虑了两种过程建模方法。提出了运输过程模拟的方法和算法。提出了一种解决海关监管过程中集装箱优化装载问题的方法。实现了圆木跨境运输仿真模型，这可以确定集装箱的最佳装载量，以最大限度地减少通关时间。建议的部分装载选项减少了海关检查的时间，从而显着降低了与木材产品运输相关的成本，以及客户拒绝交付超出计划的产品的风险。
