Developing a generic FMS for small to medium size industries of Korea

This article reports on the development of a generic FMS that is suitable for small to medium size industries. It introduces FMS construction tool named “shell”, system building methodology using it. Also, it outlines the overview of the developed FMS(KUFMS) and its computer control system. Furthermore, it elaborates on the intercommunication device that links the machinery to its control computer. The factors considered in the development of KUFMS are low implementation cost, easy implementation, case of expandability, simple modification capability.     

A meta-heuristic approach to solve a JIT scheduling problem in hybrid flow shop

In this paper we address a hybrid flow shop scheduling problem considering the minimization of the sum of the total earliness and tardiness penalties. This problem is proven to be NP-hard, and consequently the development of heuristic and meta-heuristic approaches to solve it is well justified. So, we propose an ant colony optimization method to deal with this problem. Our proposed method has several features, including some heuristics that specifically take into account both earliness and tardiness penalties to compute the heuristic information values. The performance of our algorithm is tested by numerical experiments on a large number of randomly generated problems. A comparison with solutions performance obtained by some constructive heuristics is presented. The results show that the proposed approach performs well for this problem.     

Improvements in operations management applied to a 3D simulation connected to a physical platform

Logistics are a key factor for manufacturing companies in developed countries to better exploit their competitive advantages of proximity to market and flexibility. In order to improve the management of a logistics/distribution center, this paper proposes the use of control methods based on Multi-Agent Systems enhanced with Radio-Frequency Identification. However, the best way to demonstrate the benefits of using these solutions, is to apply them to a real company; but, naturally, this is impractical. In this paper, an experimental platform composed of a 3D simulation combined with a physical miniature model is used to illustrate the proposed control methods. The set-up described here has been assembled in the AUTOLOG laboratory at the University of Castilla-La Mancha in Spain. The design of the platform is somewhat generic, allowing adaptation to different distribution problems, but has been inspired on a real local facility. The objective of this system is to provide a test-bench to experiment with multidisciplinary theories, techniques, and algorithms that can be grouped into four areas: automation and robotics, instrumentation and control, production planning, and logistics and distribution.     

A bounded dynamic programming approach to schedule operations in a cross docking platform

Cross docking is a logistic technique employed to reduce the inventory holding, order picking, transportation costs as well as the delivery time. Products arriving to the cross dock are unloaded from inbound trailers, possibly reconsolidated with other products arriving from different destinations and loaded into outbound trailers within less than 24 h. In this study, we consider a multiple receiving and shipping door cross dock environment. The objective is to find optimal (for reasonably small cross docks) or near optimal (for larger cross docking facilities) scheduling policies which minimizes the total costs related to the transshipment operations at the facility.

How to make and defend a proposal in a deliberation dialogue

In this paper it is shown how tools developed in argumentation theory and artificial intelligence can be applied to the development of a new dialectical analysis of the speech act of making a proposal in a deliberation dialogue. These tools are developed, modified and used to formulate dialogue pre-conditions, defining conditions and post-conditions for the speech act of making a proposal in a deliberation dialogue. The defining conditions set out what is required for a move in a dialogue to count as the making of a proposal by one of the parties. What is required are the conditions that (1) the move fit the requirements of the argumentation scheme for practical reasoning, and (2) the premises are propositions describing common goals of both parties or propositions that they reasonably consider means to achieve these goals. The analysis goes beyond the standard speech act approach by specifying not only the normative requirements for making a well-formed proposal, but also the requirements for responding to it by questioning or criticizing it, and the requirements for defending it.

如何充分发挥多媒体课件在语文课堂教学中的辅助作用

运用多媒体是为了辅助教学,其出发点和落脚点是为了提高教学效果,但多媒体教学不是提高教学效果的唯一途径和手段,教学中不能为了多媒体而去使用多媒体,应针对教学内容采取与之相应的教学方法、方式,合理地综合和利用各种教学媒体,包括传统媒体,这样取长补短,才能发挥各种教学方法的综合功能,取得最佳效果。     

How to keep members using the information in a computer-supported social network

Computer-supported social networks have become a significant channel for people to interact and exchange information. The success of computer-supported social networks depends on the extent to which members will stay and continue participating. Many computer-supported social networks however suffer from the problem of retaining members. Drawing from theories of user satisfaction and information adoption, we develop a model to examine how computer-supported social networks encourage members to continue participating and using the information in the network. The theoretical model is validated through an online survey of 240 users of a Bulletin Board System established by a local university in China. The results reveal that individuals will continue to use the information in a computer-supported social network when they are satisfied with their prior usage, and when they perceive that the information in the network is useful. The results also suggest that individuals’ perceived information usefulness and satisfaction are determined by information quality and source credibility in the context of computer-supported social networks. Theoretical and practical implications about computer-supported social networks are discussed.
