Construction of a computer-simulated mixed reality environment for virtual factory layout planning

To survive the cut-throat competition in the manufacturing industry, many companies have introduced digital manufacturing technology. Digital manufacturing technology not only shortens the product development cycle times but also improves the precision of engineering simulation. However, building the virtual objects needed for a digital manufacturing environment requires skilled human resources; it is also costly and time-consuming. A high precision environment with the similar resources is also needed for a high precision simulation. In this paper, we propose a method of constructing a mixed reality-based digital manufacturing environment. The method integrates real objects, such as real images, with the virtual objects of a virtual manufacturing system. This type of integration minimizes the cost of implementing virtual objects and enhances the user's sense of reality. We studied several methods and derived a general framework for the system. Finally, we developed our idea into a virtual factory layout planning system. To assign the pose and position of real objects in virtual space, we applied a circle-based tracking method which uses a safety sign instead of the planar-square-shaped marker generally used for registration. Furthermore, we developed the framework to encapsulate simulation data from legacy data and process data for visualization based on mixed reality.     

Adequate and economic factory transformability and the effects on logistical performance

Objective-oriented factory planning is a prerequisite for the economic operation of a factory. As intensive discussions in the literature as well as practical findings in factories over the years show, transformability and logistics are among the key objectives of a factory. It is striking, however, that both objectives have not so far been related to each other. Based on these findings, a method for evaluating the actual as well as the target transformability of a factory has been developed. It allows the user to assess whether the factory possesses adequate and economic transformability. In order to make the method more manageable for users in practice, a software tool is presented, and a benchmarking has been derived from the data collected by evaluating factory transformability. In addition, it has been found that transformability can influence logistics. A procedure will be presented that allows major means of adjustment to be found that improve the logistics objectives of a factory by using transformability. Finally, the outlook for future developments is discussed.

经济平衡视角下的工业遗产保护和利用——沈阳红梅味精厂“抢救式”规划实践

工业遗产保护和利用需要回答好三个核心问题:一是政府利益如何不受损,即近期土地出让金不减少,这是工业遗产留下来的重要前提;二是开发企业利益如何不减少,这是工业遗产利用由被动变主动的关键;三是公众利益如何有保障,这是规划师的核心责任。从实践来看,土地收益问题是政府决策工业遗产采用"精细利用"还是"推倒重来"的关键环节。因此,应从经济平衡视角切入工业遗产保护与利用,在此基础上,再进一步谋求政府、企业与市民三者共赢发展。目前,我国处在工业区更新较为剧烈的时期,而工业遗产保护与利用尚未成为决策者们的共识。以沈阳红梅味精厂为例,论述其"抢救式"规划实践的思路与过程,以期为当前这一特殊时期工业遗产保护与利用提供一定借鉴。     

浅谈工厂电气技术中节能技术的应用

现今工业产品生产成本构成很多,其中用电成本是绝对不可忽视的,由于工厂供电系统中的用电设备运行时会产生大量无功功率损耗,因此,从工厂供电系统中无功消耗的种类出发,减少设备投资,降低企业用电成本成为大家所共同关注的。文章主要从厂用电的节能设计、节能设备应用、厂用电管理等方面进行阐述,目的是降低厂用电量。     

Changeable Manufacturing - Classification, Design and Operation

Flexibility and changeability are key enablers for meeting the challenges of a global market. The paper first describes the main change drivers and takes then a deeper look at how changeability in a manufacturing en-terprise can be classified and operationalized. The next sections are devoted to changeability in reconfigur-able manufacturing systems, assembly systems and factories including buildings and infrastructure. New challenges, perspectives and approaches for process plan reconfiguration as well as for Production Planning and Control are discussed. Finally, the evaluation and economic justification of changeability are addressed and a control loop of changeability is presented.
