Sustainable development of a suggestion system: Factors influencing improvement activities in a confectionary company

Although the use of continuous improvement (CI) is widespread today, many organizations face problems maintaining high and sustained employee involvement in such programs. The purpose of this study was to identify factors influencing employee involvement in submitting suggestions within a suggestion system in a Swedish production company. The company had maintained a successful suggestion system for about 10 years. The study builds on a database containing all the suggestions submitted (2343 in number) within the suggestion system. The following factors were identified to influence employee involvement in submitting suggestions and hence the sustainability of the suggestion system as well: (a) Situations when the employees had a personal benefit from submitting suggestions, e.g., concerning their own work environment, contributed to long‐term sustainability of the system; (b) campaigns emphasizing different themes encouraged employees to become more active within the suggestion system; (c) employees having some of their suggestions rejected were more active in submitting suggestions than employees having most suggestions rejected or accepted; (d) a high monetary reward (80 euros and above) was not found favorable for submitting new suggestions, compared to lower rewards; (e) increased support of group suggestions contributed to a sustained and high level of activity of the suggestion system. © 2007 Wiley Periodicals, Inc.

基于CAN总线的分布式高精度时钟的实现

在许多对时间要求很严格的应用中都需要一个精确的实时时钟,如分布式控制中的测试设备就需要一个精确到毫秒级的实时时钟。集中式控制系统达到毫秒级非常容易,但是在分布式控制系统(例如连接在CAN-bus上的传感器和执行机构),由于他们没有全局的时钟节拍,使系统达到毫秒级的同步就很困难。这个问题可以通过在一定的精度内同步所有的节点时钟来解决。该文提出了一种应用在总线上的时钟同步协议,并且以CAN-bus为例在实验室中得以实现。经验证该协议能够提供一个大约10毫秒的同步精度。该协议简单且不需要额外的硬件,它只是占有一定的带宽(<20个信息/每秒)。如必要也可在大型网络中达到与外部时钟基准同步的要求。

Fabrication of LIGA-acceleration sensors by aligned molding

A technology for the fabrication of movable LIGA-Microstructures by molding was developed, which enables the cheaper production of e.g. LIGA-Acceleration Sensors [1]. For this purpose an aligned molding process had to be developed. The realized experimental setup consists of two subsystems, the molding machine and the alignment arrangement [2]. After aligning a substrate it is transported into the molding machine. An effective and extremely precise dimension translation system is required. Although during modling temperature changes appear and high forces are applied, the dimension stability during the molding process has to be guaranteed. The presented system and setup deals successfully with these conditions. An alignment quality of ± 10 μm is realized. Using the aligned molding technology temperature compensated LIGA-acceleration sensors [1] were fabricated. The proper function of the sensors was demonstrated.     

An expert system for federal tax planning

Abstract: Recent developments in a subarea of computer science called artificial intelligence have included the creation of expert systems that are capable of solving difficult applications problems which require expert knowledge for their solution. Such expert systems have been found to be useful in a number of applications (e.g. medicine, biochemistry and mineral exploration). In this paper the author presents an expert system for solving problems concerning income and transfer tax planning for individuals In developing this system, a theoretical structure and a set of decision rules were specified and then programmed into a rule-based system that had previously been used for medical diagnosis (Mycin [1]) Once the system was developed, its problem-solving capabilities were refined and verified by a panel of tax experts using a blind verification procedure. This verification step demonstrated that an expert system could be developed in that domain.
