Probabilistic Reliability Modeling for Oil Exploration & Production (E&P) Facilities in the Tallgrass Prairie Preserve

The aging domestic oil production infrastructure represents a high risk to the environment because of the type of fluids being handled (oil and brine) and the potential for accidental release of these fluids into sensitive ecosystems. Currently, there is not a quantitative risk model directly applicable to onshore oil exploration and production (E&P) facilities. We report on a probabilistic reliability model created for onshore exploration and production (E&P) facilities. Reliability theory, failure modes and effects analysis (FMEA), and event trees were used to develop the model estimates of the failure probability of typical oil production equipment. Monte Carlo simulation was used to translate uncertainty in input parameter values to uncertainty in the model output. The predicted failure rates were calibrated to available failure rate information by adjusting probability density function parameters used as random variates in the Monte Carlo simulations. The mean and standard deviation of normal variate distributions from which the Weibull distribution characteristic life was chosen were used as adjustable parameters in the model calibration. The model was applied to oil production leases in the Tallgrass Prairie Preserve, Oklahoma. We present the estimated failure probability due to the combination of the most significant failure modes associated with each type of equipment (pumps, tanks, and pipes). The results show that the estimated probability of failure for tanks is about the same as that for pipes, but that pumps have much lower failure probability. The model can provide necessary equipment reliability information for proactive risk management at the lease level by providing quantitative information to base allocation of maintenance resources to high-risk equipment that will minimize both lost production and ecosystem damage.

金砖国家装备制造业出口增加值比较研究

文章将KWW法扩展,从产业角度创新出口增加值核算方法。分解量化金砖国家装备制造业出口增加值,比较其在全球产业间的流动。不仅得到更真实的贸易利得,还实现了对出口增加值在全球行业间流动的动态分析。结果显示：（1）2000-2014年,中国该行业出口增加值经快速增长,远高于其他国家。2013年后增速回落,出口增加值率先降后升稳定于30%。中巴俄出口增加值率为30%左右,印度最低。（2）从全球流动现状看,金砖国家最终产品出口增加值占比较高。其中,中巴中间产品贸易有较大增加,深入到全球价值链分工体系。中国的重复统计项和出口返回部分最高。而俄印最终产品贸易比重不断增加。生产日益“碎片化”背景下,扩展的KWW法对研究出口增加值有重要的理论意义。

东北装备制造业区域合作的重点、模式与对策研究

东北三省装备制造业沿哈大铁路线和沿海经济带呈倒"T"型结构布局,地域特征明显;东北三省装备制造业行业门类齐全,优势产业突出,在全国占有重要地位。但东北三省装备制造业在研发上缺乏省际间的横向联系和共性技术研究;在生产上缺乏省际间的分工协作,产业关联性差;在布局上同构现象严重,缺乏与域外地区的协作互动。笔者从区域视角对东北三省装备制造业发展的现状进行了评价,阐述了东北三省装备制造业区域合作的重点领域、主要模式,并提出了加强产品开发,提高技术创新能力;强化省际之间的协作互动,提高区际间协作配套能力等区域合作发展对策,从而促进东北三省装备制造业一体化进程。

辽宁装备制造业与国内同行业竞争力的动态比较分析

本文运用因子分析法对国内31个省、市、自治区的装备制造业的竞争力进行综合比较,发现辽宁省2003年-2007年装备制造业从规模和效率上都保持着良好的发展势头,但是和其他省份相比,发展缓慢,进步幅度相对较小,说明辽宁省装备制造业还有很大的提升空间,尤其在装备制造业的效率方面,还有待改进和提升。     

Modelling end-of-life product recovery chains - a case study

European Union legislation, and existing national legislation of many European countries, mandates that manufacturers take back and recover their electronic and electrical equipment. If manufacturers are to comply with legislation, models need to be developed for these activities. Whilst infrastructural and technological deficits exist and must be addressed, so too must the organization of recovery, from a business perspective. In this paper, models of resource recovery are presented and a case study described.
