【摘要】：作为支柱型的钢铁产业是国民经济中重要的组成部分。近年来,随着全球经济发展走势的变化以及日益激烈的竞争,世界范围内的钢铁产业都受到了巨大的冲击,国内的绝大多数的钢铁企业的利润下滑甚至是亏损。我国的钢铁产量较高,但国内的钢铁物流的功能不完善和运行效率低下使其无法满足钢铁生产和贸易的发展需求。在钢铁企业中,采购和库存的相关成本占据总运营成本较大的比例。随着市场的发展越来越完善,越来越多的企业通过利用供应链管理的思想来降低库存成本、提升效益并提高服务水平以应对愈发激烈的竞争。库存管理作为企业经营活动和供应链管理的重要部分,引起了各方面的重视。钢铁行业的库存所管理的钢材具有需求不确定的特点。而钢材的需求量或可供应量也会与其价格造成相互影响。这些不确定因素会导致钢材的订货周期和库存持有量不合理,继而提高了库存成本。因此,针对不确定性研究钢材产品制定合理的库存管理策略具有重要的意义。本文以某钢铁企业为研究背景,研究钢材的库存控制方法。结合泊松需求对某钢铁企业的库存造成影响,着重考虑了基于供应商管理库存模式和随机需求的钢材库存管理方法,建立库存优化模型。分析了包括固定订货费用、持有成本、缺货成本等各种库存成本的影响,并最终利用混合算法求解出合理的订货周期和订货批量。值得注意的是,构建需求为泊松分布的模型可以更好的反映生产实际情况。但同时也增加了库存模型的复杂度,使得模型较难求解。因此,本文提出了改进的混合算法分别对构建的库存模型进行了求解。改进的算法提高了的全局寻优的效率。
[Abstract]:As a pillar of the iron and steel industry is an important part of the national economy. In recent years, with the development of global economic development and increasingly fierce competition, the world's iron and steel industry has a huge impact, the vast majority of domestic iron and steel enterprises profit decline and even loss. China's steel production high, but the domestic iron and steel logistics function is not perfect and low efficiency so that it can not meet the requirements of the development of iron and steel production and trade. In the iron and steel enterprises, related to the cost of purchase and inventory occupy larger proportion of the total operation cost. With the development of the market more and more perfect, more and more enterprises to reduce inventory costs by using the idea of supply chain management, enhance efficiency and improve service level to deal with increasingly fierce competition. As the business activities of the enterprise inventory management and supply chain management major In part, attracting the attention of the various aspects of the steel industry. The inventory management of steel has the characteristics of uncertain demand. And the demand of steel or supply will cause the price of its mutual influence. These uncertain factors will lead to steel ordering and inventory quantity unreasonable, and then improve the inventory cost. Therefore, to develop reasonable inventory management strategy for uncertainty of steel products has important significance. In this paper, an iron and steel enterprise as the research background, research methods of inventory control of steel. Combined with the Poisson demand of an iron and steel enterprise inventory impact, focusing on steel inventory management method of vendor managed inventory mode and based on stochastic demand. The establishment of inventory optimization model. The analysis includes a fixed ordering cost, holding cost, shortage cost and inventory cost effect, and finally using the hybrid algorithm For a reasonable order cycle and order quantity. It is worth noting that, for the Poisson distribution model can better reflect the actual situation of construction demand production. But also increases the complexity of the inventory model, which makes the model more difficult to solve. Therefore, this paper puts forward the improved hybrid algorithm respectively to solve the inventory model the global. The algorithm has improved the search efficiency.
