in a recent paper in this journal, yang et al. [feng yang, dexiang wu,liang liang, gongbing bi & desheng dash wu (2009), supply chaindea:production possibility set and performance evaluation model] definedtwo types of supply chain production possibility set which were proved to beequivalent to each other. they also proposed a new model for evaluatingsupply chains. there are, however, some short...
two models are commonly made use to explain the behavior of insurance industries, namely: risk-pooling and the risk-absorbing models. neither of the two models provides an acceptable definition of insurance output in the economies experiencing high inflation rate. to address the deficiencies of the present models, an alternative was proposed in the current study as based on the theory of in...
برای بررسی میزان موفقیت اجرای نظام مدیریت دانش و سنجش تاثیر آن لازم است در مقاطع مختلف بر اساس شاخص های معینی وضعیت نظام مدیریت دانش در سازمان مورد نظر را ارزیابی کرد. برای این منظور 25 مدل مطرح تئوریک و کاربردی ارزیابی سطح بلوغ مدیریت دانش ارایه شده است، که با توجه به منابع قابل دسترس، سطوح و ابعاد اصلی بلوغ 18 مدل از این 25 مدل ارزیابی سطح بلوغ مدیریت دانش مورد توجه واقع شده است. هر یک از ای...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
wall displacements and ground pressure acting on the lining of a tunnel increase with time. these time-dependent deformations are both due to face advance effect and to the time-dependent behavior of the rock mass. viscoelastic materials exhibit both viscous and elastic behaviors. thorough this study, the effect of different linear viscoelastic models including maxwell, kelvin and kelvin-voigt...
the debate over the contribution of the internet to democracy is farfrom settled. some point to the empowering effects of online discussionand fund raising on recent electoral campaigns in the us to argue thatthe internet will restore the public sphere. others claim that the internetis just a virtual mall, a final extension of global capitalism into everycorner of our lives. this paper argues f...
در این پایان نامه ضمن مطالعه کمی منابع آب زیرزمینی دشت تربت حیدریه، مدل ریاضی آبخوان نیز تهیه شده و در نهایت پتانسیل آبهای زیرزمینی منطقه با یکسری پیش بینی هایی با نرخ خای مختلف تغذیه مورد مطالعه قرار گرفته و پیشنهاداتی با توجه به وضع موجود و آتی آبهای زیرزمینی ارائه گردیده است . نظر به اینکه مدل تفهیمی (conceptual model) و تجزیه و تحلیل سیستم آبخوان خیلی به تهیه مدل عددی کمک می نماید، لذا سیست...
this study considers the level of increase in customer satisfaction by supplying the variant customer requirements with respect to organizational restrictions. in this regard, anp, qfd and bgp techniques are used in a fuzzy set and a model is proposed in order to help the organization optimize the multi-objective decision-making process. the prioritization of technical attributes is the result ...
some researches made in the field of agency problem issue, deal with the role of control systems regarding owners and managers. in this research the relationship between the two control mechanisms, namely the voluntary disclosure (external control mechanism) and outside directors (internal control mechanism), which are reductive of agency problems, has been studied. for this reason, a sample ...
abstract due to low spatial resolution or simplifying of some micrometeorological phenomena, atmospheric general circulation models are not able to give a good estimation for weather conditions over study area. so their outputs should downscale into weather stations scales. in this research data of hadcm3 downscaled by using lars-wg5 with three scenarios, confirmed by ipcc including a1b, a2 and...
