利润预测是企业进行科学管理的重要环节。利用随机弹性理论研究产销量为随机变量时,利润对产销量的随机弹性,给出了利润弹性的分布函数和概率密度函数,销售量的变化对利润弹性产生影响。进一步论证了利润弹性的经济意义。通过实例研究了当产销量服从某种分布时,利润弹性的变化范围及在该变化范围的可信度。     

EOQ库存控制探析

经济订货批量模型又称整批间隔进货模型EOQ模型，英文为economic order quantity，该模型适用于整批间隔进货、不允许缺货的存储问题，即某种物资单位时间的需求量为常D，存储量以单位时间消耗数量D的速度逐渐下降，经过时间T后，存储量下降到零，此时开始定货并随即到货，库存量由零上升为最高库存量Q，然后开始下一个存储周期，形成多周期存储模型EOQ模型曾经广泛地应用于国外企业的存货管理，且收到良好的经济效果。目前，我国广大管理者也早已熟悉EOQ理论，并且也尽可能地采用EOQ模型以帮助其提高制定存货管理有关决策的质量。     

随机型商品库存系统的数学模型及MATLAB仿真

商场在经营中必须库存一定数量的商品,以满足销售的需要。商家进货要有计划,进货过多,库存量较大,占用的流动资金也越大,库存费增加;进货过少,一方面会增加订货次数而增加采购成本,还会造成因缺货造成利润损失和商场信誉损失而影响收益。本文对商场经营者十分关心的库存量问题,以商品库存总费用最小为目标,根据随机型库存系统的特点,建立了商品库存模型,并通过计算机仿真获得最优订货点和最优订货批量,寻找最佳进货方案,为合理进货提供依据。

电子商务企业物资采购环节管理研究

而随着我国企业的快速发展，所需要的物资种类与质量的要求也越来越高，传统的采购方式越来越无法满足企业物资采购环节的需求，因此，将电子商务技术运用到企业物资采购环节成为大势所趋。本文以电子商务物资采购的概述为研究基点，分析企业采用电子商务进行物资采购的优势，并论述企业运用电子商务进行物资采购的管理角度，以期电子商务技术能够更广泛的应用到我国企业物资采购环节中。     

试谈施工企业的存货管理

从财务管理的角度讲，企业存货每次采购量的大小和间隔时间的长短，影响着企业的经济效益．在全年需用量和市价固定的情况下，存货的购里成本一定，每次采购量越大，平均库存量越大，供应间隔期越长，订货成本越小。

Economic Keywords in 2007 in China

RMB exchange rate The exchange rate of Renminbi,the Chinese currency, witnessed an appreciation of around six percent to one U.S. dollar this year. On December 13, the central parity rate stood at RMB 7.3568 against one dollar,according to the Chinese Foreign Exchange Trading System, breaking the 7.36 mark.     

Changes in market structure in Poland

This article describes the market structure in Poland during the first stages of the economic reform of 1981–1983. The negative consequences of monopolistic market structure in a centrally planned economy are discussed. The possibility of market-structure diversification by companies is presented.     

Developments in Consumer Protection in India

This paper surveys the major developments in the field of consumer protection in India since 1984, when the statutory provisions for regulating unfair trade practices were incorporated for the first time.Among the developments described in the paper is the strengthening of provisions for consumer protection through amendments to the Act regulating restrictive and monopolistic trade practices (the MTRP Act). Public-sector undertakings and co-operative societies have been brought within the purview of the Act, and consumers have obtained the right to participate in inquiry proceedings before the MRTP Commission.Consumers and their associations have been given the right to seek redress of grievances arising out of the violation of certain pieces of legislation, including the Drugs and Cosmetics Act. The Consumer Protection Act, 1986, was enacted in order to provide speedy and inexpensive redress of consumers' grievances. Redress can now be sought before any consumer court also for negligence or deficiency in medical services.The Bureau of Indian Standards Act, 1986, has strengthened the measures for the standardisation and quality control of manufactured goods.A Consumer Welfare Fund has been set up to provide financial assistance to voluntary consumer organisations and for the general development of consumer movement in the country. A spurt in voluntary consumer organisations in different parts of the country can also be observed.Other developments include the establishment of a separate Department of Consumer Affairs in the Union Government and the setting up of a Consumer Product Testing Laboratory.

Healthy Investments in Investing in Health

This article discusses socially responsible investing (SRI) and tobacco. SRI allows investors, both institutional and individual, to express their concerns and make their social and ethical stands known to the companies they invest in and patronize. The tobacco industry is active in every country on the globe and generates huge profits, while tobacco use is responsible for 4 million deaths every year.The authors explore past and current views on investment in tobacco, partly based on a survey conducted by the Tobacco Free Initiative of the World Health Organization (WHO). There is clearly a trend toward divestment from tobacco for both ethical and financial reasons. Tobacco-free investments can be both ethically sound and financially profitable.     

Conflict in Supplier–Retailer Relationships in the Brewery Industry in Cameroon

The authors develop a theoretical framework to explain conflict in supplier–retailer relationships. In addition to traditional influence strategy variables, the framework links conflict to retailer dependence and supplier formalization. The framework is empirically tested in the Cameroonian brewery industry. The findings support the view that channel conflict is inversely related to retailer dependence and supplier formalization. Contrary to expectations, the use of noncoercive influence strategies (information exchange and recommendations) has no significant effect on conflict, while, as expected, the use of coercive influence strategies (threats and promises) increases conflict.
