中国生猪养殖业规模化影响因素研究

在中国农业产业中,养殖业率先进入规模化发展阶段。基于1998-2011年省际面板数据,运用FGLS法考察生猪养殖规模化的决定因素,发现技术进步、规模经济效益、饲料加工业发育、城乡猪肉消费、交通条件、劳动力非农化、劳动力文化水平以及财政支持政策对规模化具有显著影响。进一步利用回归分解法识别关键因子,结果表明,规模化发展主要取决于四股力量,其中市场拉力是主要的源动力,而交通条件和劳动力文化素质则是重要支撑力,生产扶持政策也形成一定推力,四者的贡献率分别为27%、19%、10%和3%。

会计委派制:遏制腐败的创新之道Accounta

会计委派制是指由政府统一向所属部门、企业、事业单位委派会计并对其进行统一管理的制度。由于会计委派制具有保证国家法律法规执行、实行全方位实时监督、建立利益分离机制和降低廉政建设成本的优点 ,在腐败严重、反腐刻不容缓而又效果不佳的今天 ,它不失为廉政建设的一种有效手段。会计委派制关键是会计不腐败 ,因而在运行中必须建立任职资格、职务保障、生活保障、任职回避、定期交流和奖励惩处等制度。这样 ,会计委派制度才能取得预期效果     

略说古代史家史学批评的辩证方法

唐代史家刘知畿在总结以往史学发展的基础上撰成《史通》一书,这标志着中国古代史学批评发展到更加自觉的境界。它在理论上的提升和专题评论的广泛展开,上承魏晋,下启两宋元明,大多反映出辩证的认识和方法．极大地丰富了中国古代史学批评的内涵及其史学价值和理论意义。总结这一辩证方法运用的传统,对当今史学批评的开展,仍有一定的借鉴作用。

Abstract：

LIU Zhi-ji,as a historian of the Tang Dynasty,writes the book Shi Tong on the basis of summa- rizing the former development of historiography,which indicates that the ancient Chinese historical criticism has developed into a stage with more self-consciousness. The advancement in the theory and the expansion in the discussion of certain issues,inheriting from the Wei and Jin Dynasty and initiating the Song,Yuan and Ming Dynasty, mostly reflect the dialectical method and understanding, and greatly enriches the conno- tation,historical merits and the theoretical significance of the historical criticism in ancient Chinese criticism of historiography. Summarizing the tradition of using this dialectical method will inspire the development of today＇s historical criticism.     

Multiobjective optimisation of production,distribution and capacity planning of global supply chains in the process industry

The performance of a supply chain should usually be measured by multiple criteria. We address production, distribution and capacity planning of global supply chains considering cost, responsiveness and customer service level simultaneously. A multiobjective mixed-integer linear programming (MILP) approach is developed with total cost, total flow time and total lost sales as key objectives. Also, two strategies to expand the formulation plants’ capacities are considered in the model. The ε-constraint method and lexicographic minimax method are used as solution approaches to tackle the multiobjective problem. Finally, a numerical example is investigated to demonstrate the applicability of the proposed model and solution approaches.     

Performance of TOC based finite capacity material requirement planning system for a multi-stage assembly factory

This paper aims to develop a finite capacity material requirement planning (FCMRP) system based on TOC philosophy (TOC-MRP) for multi-stage assembly factory that has some bottleneck stations. The proposed TOC-MRP system tries to load and schedule operations on bottleneck stations in a manner that they are free of idle time and overtime. The schedules on non-bottleneck stations will be arranged until they are not conflicting with those on the bottleneck stations. The non-bottleneck stations are allowed to have idle time and overtime if necessary. To analyse whether TOC-MRP is effective, it is compared with a FCMRP method that does not adopt TOC philosophy. The experimental results reveal that the TOC-MRP outperforms the FCMRP without TOC philosophy.     

A Taguchi-based Kansei engineering study of mobile phones at product design stage

This article is aimed at applying Taguchi method in Kansei engineering and explores a way to integrate it into an industrial product design stage. Emotional customer needs are derived using Kansei image word pairs. The Taguchi-based approach is validated by a case study with mobile phones. Experimental work in implementing the proposed approach was able to suggest design attributes of a mobile phone that are essential to be considered at the product design stage to satisfy the customers’ expectations and hence to increase the company's sales.     

An economic model for the quality selection problem

The object of an economic model for the quality selection problem is to select the best parameter value for an input quality characteristic (X) so that the quality loss incurred on an output quality characteristic (Y) is minimized. The relation function between Y and X is assumed to be known throughout the article. In the work of Taguchi's experimentations, the selection of best parameter values is solved by two-step optimization when Y is adjustable. In the article, it is further extended to the case where Y is non-adjustable. An economic quality selection model with a general relation function is proposed based on a Taylor-series method for both adjustable and non-adjustable cases. A special case of a quality selection model with a quadratic relation function is also studied. A circuit example provided by Taguchi is presented to illustrate the use of this model.
