【摘要】：钢铁企业作为传统的、大型的制造业之一,具有生产流程复杂、原材料消耗大、产品多样化以及产品运输多样性的特点。因此,在生产过程中,钢铁企业应注重对物流成本的有效管控,实现物流成本的节约,降低企业的总成本,从而保持企业在国际市场上的竞争力。目前钢铁企业物流成本控制方面的研究,主要都是从某一个具体的物流环节进行分析研究,没有从系统的、整体的角度去看待物流成本控制的问题。而众所周知的是,在企业物流成本控制的过程中,一些物流子系统之间存在着“效益背反”的现象,某一子系统的物流成本的有效控制可能带来的是其他子系统物流成本的偏高。因此,在研究钢铁企业物流成本控制的问题上,应以系统的、全面的角度进行分析研究,从而实现企业物流总成本最低的目标。本文首先介绍了物流钢铁企业物流成本控制的涵义、内容等;并B钢铁企业为例,介绍了B钢铁企业的物流系统成本控制现状,同时对B钢铁企业物流成本控制目前存在的问题进行了分析;接着利用系统动力学的方法,结合Vensim仿真软件构建了B钢铁企业的物流成本控制的系统动力学模型,将B钢铁企业的实际数据输入到模型当中,得出仿真结果;通过对仿真结果的分析,提出了相应的控制B钢铁企业物流成本的三种策略,三种策略主要是从运输成本控制、库存及相关成本控制以及生产流程中的物流控制三个方面提出的;然后对提出的三种策略,利用构建的B钢铁企业的物流成本控制模型进行仿真分析,从而得出本文的结论;最后对全文进行总结,提出未来的研究方向。本文的研究结果表明,目前B钢铁企业的物流成本控制系统有很大的提升空间,目前提出的三种策略都可以有效的降低企业的物流成本。B钢铁企业在实际的物流成本控制中,应将三种策略组合,从而达到最优的效果。同时,通过本文的研究可以看出,基于系统动力学方法的仿真方法是非常适用于钢铁企业物流成本控制问题的,这也是未来物流成本控制问题的一个研究方向。
[Abstract]:As one of the traditional and large-scale manufacturing industries, iron and steel enterprises have the characteristics of complex production process, large consumption of raw materials, diversification of products and diversity of product transportation. Iron and steel enterprises should pay attention to the effective control of logistics cost, realize the saving of logistics cost, reduce the total cost of enterprises, so as to maintain the competitiveness of enterprises in the international market. It is mainly from a specific logistics link to carry on the analysis research, did not look at the logistics cost control question from the system, the overall angle. But as we all know, in the enterprise logistics cost control process, Some logistics subsystems have the phenomenon of "benefit back-to-back". The effective control of logistics cost of one subsystem may lead to the high logistics cost of other subsystems. Therefore, in the study of steel enterprise logistics cost control, This paper first introduces the meaning and content of logistics cost control in logistics iron and steel enterprises, and B iron and steel enterprises as an example. This paper introduces the current situation of logistics system cost control in B iron and steel enterprises, and analyzes the problems existing in logistics cost control of B iron and steel enterprises, and then makes use of the method of system dynamics. Combined with Vensim simulation software, the system dynamics model of logistics cost control in B iron and steel enterprise is constructed, the actual data of B iron and steel enterprise is input into the model, and the simulation result is obtained. Three strategies are put forward to control the logistics cost of B iron and steel enterprises. The three strategies are mainly put forward from three aspects: transportation cost control, inventory and related cost control, and logistics control in production process. Then, the three strategies proposed are simulated and analyzed by using the logistics cost control model of B iron and steel enterprises, and the conclusion of this paper is drawn. Finally, the paper summarizes the full text and puts forward the research direction in the future. The research results of this paper show that, At present, the logistics cost control system of B iron and steel enterprises has great room for improvement. The three strategies put forward at present can effectively reduce the logistics costs of enterprises. B iron and steel enterprises should combine the three strategies in the actual logistics cost control. At the same time, through the research of this paper, we can see that the simulation method based on system dynamics is very suitable for the logistics cost control of iron and steel enterprises. This is also a research direction of logistics cost control in the future.
