An information management system concept with a web interface is proposed for integrating food recycling chain managements. The recycling problem is much discussed in various markets such as food, containers and packaging products, home appliances, construction materials, and automobiles. Although the word "recycling" is used over the different recycling field, the characteristic and the legislation of the recycling object are different in each field. It is necessary to understand the feature of requirements for information management systems to carry out an efficient, available recycling in each recycling field. In this paper, the requirements in the above recycling fields are compared and characteristic requirements especially for food recycling are extracted. And an information management system concept corresponding to these demands is proposed. This system has an integrative management interface which is designed to be opened to retail shops or recycling manufactures through a web interface. Recycling information is stored in a database of the system directly through the recycling works and is used to get control over daily works, quality management of recycled feed materials, or to make reports to corresponding recycling law. Thus efficient and inexpensive information management for the recycled items can be realized.
Progressive information technology requires manufacturers produce higher quality and lower cost products and get them to market faster. In the future, a business society may be formed with virtual enterprise in which each company divides the work in collaboration and shares the results of the product idea and product scheduling. For an infrastructure supporting such a multimedia business society, business media infrastructures are required where each company promotes effective data exchange, information delivery and sharing in their business processes. We propose a system architecture of the business media providing service composed of a network layer, a service layer and an application layer. In addition, the method of information organizing and the sharing of product designs uses collaboration between companies. We propose an information organizing and sharing method as a means of getting for the distributed task information available on the internet or on intranet in the product design field. In this system, there is information search selectively gathering relevant words defined by a task terminology dictionary. Meta-data described the relation between gathered data are created and mutually connected with one another using the task model defined by the task procedure. The meta-data refers to knowledge information for the retrieval of design task information. Metaknowledge composed of the mentioned task model and gathered data, which is stored in a common database, results in viewpoint sharing of a company's intemal and extemal information. This method is adapted to a product design task for an example implementation. We present the design information organizing and sharing method and a prototype of a retrieval support system for design task information. This system enables us to quickly retrieve the task adapted information from a large number of design documents that contain design processes.
An autonomous information system design for item management is proposed for an efficient supply chain management. By using rewritable RF-ID tags instead of popular bar codes as a job ID, which represents a manifest of an item, each processing system directly communicates with the tag information of each item, and autonomous item management can he realized. The following four basic functions are designed, to introduce new items, to link each item to processes, to update item information, and to acquire process records. In a prototype system, which handles RF-ID tags as processed items, selecting correct items and processes according to a production plan are confirmed.
