摘要
舰艇出海执行任务期间,需要携行一定种类和数量的物资自给。文中研究了这种单级供应条件下,如何确定备件最优携行量的问题。建立了以服务水平为目标,以资源为约束的目标规划模型,模型考虑了随机提前期和备件重要度。提出一种基于边际效费比的增量法用于求解这个模型。最后,给出一个算例并得到了一些结论。
In order to meet the self-supporting requirements, numerous items are carried on shipboard when ships are at sea. An optimizing carried amount of spare parts on single-level provision is discussed in this paper. The model of goal programming is provided, with the goal for service level and resource restrictions. The random lead time and the criticality of spare parts are taken into consideration. An augument method based on the marginal efficiency ratio is provided to solve the model. An example is presented to acquire some useful information.
