SBA中PLM的研究与应用

以一种典型的产品生命周期管理(PLM)软件--SmarTeam为例,研究了基于仿真的采办(SBA)中PLM的应用.PLM用于管理SBA中的不同资源,共享产品数据.此外,从三个方面扩展了PLM:首先,使用PLM的开发接口和ActiveX技术将PLM与Matlab集成,使用户可以在PLM中浏览Matlab生成的控制系统文件;其次,使用PLM的工具以及PLM和MS Project的开发接口将PLM与Project集成,提高了PLM的项目管理功能;最后,使用PLM工具并设置SBA资源建立SBA权限控制模型,使PLM可以管理SBA系统的所有权限.PLM的应用及扩展使其可以更好的支撑SBA系统,同时解决了SBA复杂权限管理的问题.

HOW ARE PRODUCT-SERVICE COMBINED OFFERS PROVIDED IN GERMANY AND ITALY？ ANALYSIS WITH COMPANY SIZES AND COUNTRIES

A new business concept that offers products and services in a different way of traditional product-sales businesses is getting more attention especially in manufacturing industries. This paper investigates how this new business by means of integration of products and services is achieved in Germany and Italy. In addition, it analyzes the differences according to the company sizes. The results include that this type of business is in many cases motivated by their focus on customers and often consists of physical products and their maintenance. The Italian companies, as opposed to the German ones, often design their physical products specifically for this type of offers. From the analysis based on the size difference, small companies are found to achieve specific design for this type of offers while owning physical products. There do not seem to be any established methods or tools developed to support the development of such offers and within such methods/tools there would be room for more adaptation in form of physical product design.     

基于混合定价机制的高估价顾客购买策略

Analysis on Influential Factors of Corporate Environmental Management Level Based on ISM

Environmental problem is one of complicated social problems. According to the level of corporate environmental management, there are many influential factors, and their relations are also complicated. In this paper, we analyzed influential factors of corporate environmental management through consultation of experts. And based on the analysis, we applied interpretative structural modeling（ISM） to classify 13 influential factors into 3 levels. We hope it will be useful for the subsequent research and evaluation of corporate environmental management level.
