民间资本保值确定性存贮模型构建与运用

民间资本作为我国经济的重要组成部分,其科学的发展和合理的引导影响着我国经济的稳定可持续发展。本文通过对民间资本保值问题的研究,提出了民间资本保值确定性存贮模型。同时分析了民间资本保值存贮成本,认为存贮成本取决于通货膨胀和银行利率,提出民间资本保值问题关键在于民间资本名义价值的保值,以及民间存贮成本与投资需求与投资收益率之间的关系。文章通过构建民间资本保值存贮模型,为民间资本的投资设立相应的预警体系,以确保民间资本的合理保值增值,从而完善我国金融的监管机制。

对(s,S)型随机存贮策略模型的改进

经典的(s,S)随机存贮策略的决策模型已经被大家广泛认识和接受,但是该模型在考虑存储成本的时候忽略了期初库存的减少不是瞬间发生的,而是一个持续的过程,那么整个存贮成本就不应该仅仅是对期末库存余量的持有成本。为此,本文针对其不足进行了一定的改进,使得(s,S)随机存贮策略的决策模型具有更广泛的适用性。

缺货损失厌恶的报童问题

报童问题是随机存贮管理的基本问题之一。在预期理论的框架下,我们通过引入损失厌恶参数,基于损失期望最小原则,对经典的报童问题进行了重新思考,给出了缺货损失厌恶的报童的最优定货量的计算公式及订购量与期望损失关系的数学模型.     

也谈库存控制

库存是为了满足未来需求而暂时闲置的有价值的资源。因而库存管理的首要任务应该是在不断降低库存成本的基础上保证生产的正常进行。库存管理的对象是对整个库存系统进行管理,补货环节不断地将货物补充到仓储环节,货物在仓储环节被暂时储存后,再被送往市场环节。在这一过程中,补货活动具有一定的主动性,依管理者的决策而定,而向市场的出货则一般是被动的活动,每当市场产生需求时,才实施出货活动。     

Asymmetric volatility of basis and the theory of storage

The theory of storage states that the marginal convenience yield on inventory falls at a decreasing rate as inventory increases. Previous literature has tested this hypothesis using the so‐called “direct test” approach, which employs a direct measurement of inventory levels, or the “indirect test” approach, which examines the relative variation of spot and futures prices and the relative variation of negative basis to positive basis as alternative proxies for inventory levels. The rationale behind the indirect test is based on the hypothesis that futures prices are less variable than spot prices when inventory is low, and have similar variability when inventory is high. The authors propose a “unified test” of the theory of storage that incorporates aspects of both direct and indirect tests in an ARMAX‐asymmetric GARCH model framework. © 2005 Wiley Periodicals, Inc.

AN INVESTIGATION INTO THE EFFECT OF FULL‐SCALE SUPPLY CHAIN MANAGEMENT SOFTWARE ADOPTIONS ON INVENTORY BALANCES AND TURNS

Supply chain management (SCM) software vendors, analysts, and others claim that firms implementing SCM software stand to benefit by being able to reduce inventory holdings and increase inventory turns. We theorize that full‐scale implementations lead to system‐wide inventory optimization, which in turn leads to cost improvement associated with inventory balances and turns. To examine the question, we develop an analytical model of inventory optimization, then analyze the effects of the model with a numerical experiment, and finally confirm the results with an empirical examination. We find that firm‐wide implementation is significant in explaining improvement in inventory metrics, relative to pre‐implementation metrics for our sample. Our empirical tests indicate that implementing SCM software across only a portion of the firm does not impact inventory metrics, but that the scale of implementation does. More precisely, we find that firms implementing SCM software across the entire company significantly improve both inventory turns and inventory as a percent of revenue relative to partially‐implementing firms and non‐implementers.     

基于供应链管理的制造型企业库存优化研究与实践——以AIP公司库存管理优化为例

库存不仅占用流动资金,增加储运成本,而且还会带来诸如安全、变质、贬值等一系列风险.因此,如何科学地削减库存总量,保持合理的库存水平,实现企业低成本运营,一直是企业界所关注的热点问题.鉴于此,本研究在全面库存管理思想的指导下,分析了AIP公司的库存管理现状,通过加强物流管理、改善内部供应链、扩大信息共享范围等手段,解决了库存量偏高和库存结构不合理问题,实现了优化库存总量、降低经营成本和提高市场竞争力等企业目标,并据此提出库存管理内容和模式的一些创新观点,从技术层面找到了普遍适用的库存管理与控制的有效措施,以期对制造型企业的库存管理有借鉴意义.

The theory of storage in the crude oil futures market,the role of financial conditions

This study examines the impacts of inventory and financial instability on the basis of the crude oil market. The results show that, first, the basis rises with inventory, and this effect is higher during low inventory regimes. This validates the theory of storage in the crude oil market. Second, the basis rises with financial instability, and this effect is higher during turbulent regimes. These results warn the oil market participants that, to make decisions based on the basis variation, traditionally known as a signal of scarcity or abundance, the underlying cause of the variation has to be considered.     

ABC Inventory Management Support System With a Clinical Laboratory Application

Many manufacturing and service organizations invest a large amount of capital in inventory. For this reason, it is important for inventory managers to reduce the costs associated with inventory. Firms that carry a variety of items require a classification system for the effective management of inventory. The ABC support system is a well-established inventory planning and control method that is used to manage different classes of inventory and reduce inventory costs concurrently. This paper presents a decision support system for ABC inventory management that can be used by managers to determine the efficiency of their inventory policies and to evaluate inventory decisions. The mathematical formulas to support inventory decisions are discussed. Since managers must manage in term of dollars, the quantitative tools are explained in terms suitable for management.
