基于博弈分析的供应链牛鞭效应削减对策
The Suggestions to Whittle down the Bull Whip Effect Based on Game Analysis
 [PDF]


Management Science and Engineering (MSE) , 2014, DOI: 10.12677/MSE.2014.34014
Abstract:
本文设定了一个IT企业的链状供应链,考虑到了供应链成员可能存在有意识削减牛鞭效应的行为,即可能其生产的量比其接到的需求报告的量要小。对供应链各个成员进行完全信息静态博弈分析,得出如下结论:由于企业追求自身利益最大化,存在故意扩大实际需求的败德行为;因为渠道很重要,下游企业具有很大话语权,上游企业不得不按照下游企业的要求进行生产,从而造成供应链库存过剩,使供应链整体利益遭受损失;只有供应链成员企业自觉规范自己的行为,供应链才能获得最大利益。为了实现这一目标,本文从供应链成员契约方面和信息技术方面给出了建议。
This paper is based on a catenulate supply chain of an IT enterprise, and has considered the action that the members of the supply chain may whittle down the bull whip effect consciously, namely the yield may be less than the need they have received. Conduct a static game analysis under complete information and draw the following conclusions: as the enterprises pursue the maximal profit, they may conduct an immoral behavior that report a need larger than their actual demand; as the canal is very important, the downstream firms have a larger speaking right, the upstream firms have to produce as the downstream firms’ requirements, and this will result in an excess inventory of the supply chain, and then the supply chain will suffer for it; only if the members of the supply chain regulate their own behavior can the supply chain obtain the largest profit. In order to achieve this aim, this paper gives some suggestions in the aspects of contract of the supply chain members and information technology.

Abstract:
铁皮石斛营养丰富,在贮藏过程中会出现霉变、失水、发芽等问题,而霉变是影响铁皮石斛商业价值及食用价值的主要因素。铁皮石斛鲜品经清洗后采用紫外照射、乙醇处理及高压蒸汽三种处理方式对铁皮石斛的表面进行保鲜前处理,并对处理后的铁皮石斛进行微生物检测,优选杀菌效果较好的处理组在5℃及25℃进行贮藏试验。结果表明,采用75%乙醇对铁皮石斛鲜品浸泡处理3 min能达到较理想的杀菌效果,且处理后的样品在5℃贮藏49 d过程中能保持较好的感官品质。
Dendrobium candidum is a nutrient-rich Chinese herbal medicine. Mildew, dehydration, budding and some other problems may appear in the process of storage. Mildew is the main factor affecting the commercial value and the edible value of Dendrobium candidum. Three different treatment methods of irradiation of ultraviolet, alcohol treatment and high temperature steam were used on the surface of fresh Dendrobium candidum to select the effective sterilization method. The results showed that fresh Dendrobium candidum soaked in 75% ethanol for 3 minutes can get a better sterilizing effect, and treated samples can maintain good quality during storage.

Abstract: 从制度经济学角度来看,《中华人民共和国劳动合同法》作为国家一项重要的法律制度,其作用及影响不仅是规范企业用工行为和劳资关系,还对国家社会进步、经济发展有着极大的激励作用。通过对微观个体的行为约束和引导,《劳动合同法》将有助于资源优化配置,促进人本社会、法治社会的建设,引导企业建立社会公民意识,加快技术结构升级,进而实现社会的可持续发展。在当前形势下,必须进一步统一思想,充分认识《劳动合同法》在国家社会进程中的重要作用,破除种种干扰,加大《劳动合同法》的执行力度。
In the sight of the institutional economic, “The People’s Republic of China Labor Contract Law” is an important social and political legal system, its role and impact is not only regulating to behavior and labor relations about business, but also has a great incentive to social progress and economic development. Through behavior constraints and guidance to the individual, “Labor Contract Law” will help to optimizing on the allocation of resources, promoting building the humanistic community and law community, guiding enterprises to establish a social and civic awareness, accelerating technological upgrading, so as to realize the community to sustainable development. In the current situation, we must further unify thinking, fully aware of the important role of “Labor Contract Law” in our society, eliminate all kinds of interference, enforces en- forcement to the “Labor Contract Law”.

Abstract:
在传统的经济学中,经济系统的发展应当是开放的持续增长的过程,然而资源的有限性限制了经济系统的最终规模,目前一般认为经济系统的发展轨迹应当是逐步趋于稳定状态。因此研究经济系统的是否能够达到稳定状态以及相应的控制算法对于经济学的研究具有重要的意义。本文对投入产出经济学中的离散广义动态投入产出模型进行模拟与控制,以使经济系统的各个部门能够协调发展,并趋于一个稳定的发展状态。通过使用新的数学方法,广义投入产出模型不需要转化成一般的线性模型可以直接研究其稳定性,从而减少了研究的复杂性。本文首先研究动态投入产出模型能够趋于稳定状态的条件,并基于此设计相应的控制算法,最后利用计算机编写相应的模拟与控制程序。
This paper deals with the problems of stability and computer control for the economic discrete-time singular dynamic input-output model. The singular dynamic input-output system is directly treated with without converted to general system. A sufficient stability condition under which the model is admissible is proved. Base on this, a state feedback stability criterion is established. Finally, the corresponding method of computer simulation and control is pro-vided.
