基于ERP沙盘模拟的企业管理培训模式研究

企业培训是一种有目标、有计划、有步骤的学习,有助于改善和提高员工的知识技能、工作方法和工作绩效,不断推动个人和企业不断进步,实现企业目标。本文在具体介绍ERP沙盘模拟的基础上,将其应用于企业培训,构造一个新的体验式的培训模式,并对该模式的实施策略进行了说明,分析了该模式的特点和优势,体现出了传统培训模式所无法比拟的优越性,该模式提倡学员学为主,老师教为辅的培训方式,有利于提高培训效果。     

ANALYSING THE STRUCTURE OF THE ECONOMY USING PHYSICAL INPUT–OUTPUT TABLES

Analyses using physical input–output tables (PIOTs) are key to understanding the physical metabolism of economies, since they relate production to the generation of emissions and use of resources. Two methods have been developed to calculate the primary resources and emissions associated with a given final demand. However, one of these alters the PIOT, revealing different technical coefficients and Leontief inverse matrices. Which method should be used for structural analysis? In this paper, I compare both methods, explain the structural differences between them and illustrate the latter through a backward linkage analysis. I find that only one method is suited to the analysis of the physical structure of the economy, since it comprehends both the production of goods and associated emissions. The method is identified as a new model capable of tracing by-products as final outputs. Finally, I generalise both methods to analyse PIOTs including several emission types.     

Tests based on φ-divergences for bivariate symmetry

In this paper we introduce a family of test statistics for testing symmetry based on φ-divergence families. These test statistics yield the likelihood ratio test and the Pearson test statistic as special cases. Asymptotic distribution for the new test statistics are derived under both the null and the alternative hypotheses. A simulation study is presented to see that some new test statistics offer an attractive alternative to the classical Pearson test statistic for the problem of symmetry. Received: May 2000

基于价值增值的比较优势研究

本文基于Hummels et al．（2001）的分析框架,利用OECD提供的投入产出数据库,计算并比较中国与其他29个主要经济体产品增值率指数及增值比较优势指数。实证结果显示,我国的比较优势产业主要集中在制造业,然而这些比较优势产业的增值率不仅低于服务业和农矿制造业,并大大低于同一产业的世界平均水平。

Measurement of reciprocity in a village through social networks

This paper examines measuring of interdependency among households through their transactions by using information of individual villagers in a disadvantaged area in a developing country. To obtain the information, we created a village input–output table (VIOT) from household survey data conducted in a rural village in Lao PDR in 2015 and 2016. Because each household in the village is not only a producer but also a consumer who is trading products and consuming them, the VIOT is a simple but useful tool to know the economic transactions among villagers. The main findings are that four higher-income families, which mainly trade rice very frequently, are playing key roles in the village economy, and the interdependency among higher-income households is stronger than among lower/middle-income households. Additionally, this method can be used to form an economic policy such as poverty reduction because of informing households playing a key role in the village.

Workflow process modelling and resource allocation based on polychromatic sets theory

In workflow management, studying the relationship between workflow process activities and resource allocation is one of the interesting research topics. Polychromatic sets theory (PST) is a relatively new mathematical theory which is especially suitable for treating such problems. Based on PST, this paper proposes a framework of workflow process modelling and resource allocation. As the theoretical foundation, polychromatic sets (PS), polychromatic graph (PG) and isolation operation (IO) of the PS are introduced. Special net structure (SNS), a special PG with colourless nodes and concolourous edges, is also introduced, and a new workflow process model and its verification algorithm are presented. Furthermore, a workflow resource model based on the entity of PS is developed. Based on IO of PS, the allocation mechanism that considers workflow process and workflow resource is proposed. Finally, a case study is provided to demonstrate the effectiveness of the above-mentioned theory and method.     

“暂停”战术在男子高水平乒乓球比赛中的作用

暂停作为技战术的一部分,暂停时机运用在乒乓球比赛中的作用还是很重要的,如果教练员或者运动员在比赛中能很好的运用比赛暂停的时机,对运动员的比赛胜负还是有很大的影响。本文通过运用文献资料法、数理统计法、逻辑分析法对暂停在比赛中运用时机对比赛结果影响的分析,可以看出在男子高水平的乒乓球比赛中合理运用暂停时机对比赛结果有很大的影响。
