Communication of an impending hazard to people in near real time is critical. The purpose of this paper is to develop an internet‐SMS based geo‐hazard warning communication system.

A warning system based on an internet‐resident concept and the available cellular mobile infrastructure is proposed in this study. The functionality of the system is modular in architecture.

The messages have been transmitted in a set of 20 SMSs six times, to locally‐owned mobile numbers, resulting in a total number of 120. It has been found that 58 messages got delivered within ten seconds, the rest within 40 more seconds. The threat messages reached the impending threat areas within acceptable time delay.

The paper describes the implementation of a novel and stand‐alone system for dynamic hazard warning. Cellular or mobile phone, a gadget used by common man, is expected to be the best proposition to effectively warn people individually and to propagate hazard messages to users in large regions ubiquitously. The concept allows pervasiveness and redundancy, important to withstanding hazards and bringing several original elements through the development of this “fast warning system”, as current warning strategies do not include such solutions.

X.400, one of the first OSI Application layer standards to be ratified, has generated considerable interest in the computer and telecommunications industry. Software vendors and network service providers are now marketing X.400‐based products. Message handling systems based on X.400 support interpersonal electronic mail services and also provide a generic mechanism for the exchange of information between computer systems. This ability to support information transfer between computer systems is the real contribution of X.400. Telecommunications based on this standard can be applied to library operations such as interlibrary loan, acquisitions and document delivery.

Introduction Electronic mail, in the broadest sense; is not by any means a new technology. From the earliest days of telegraph; back in the 19th centuary; electronic media have been used to transmit textual information between distant points of the globe. Today the humble but ubiquitous telex machine is perhaps the best representative of this form of communication.

The Interlibrary Loan (ILL) protocol is a standard based on the OSI Reference Model that permits ILL messages to be exchanged between heterogeneous systems. By defining a standard for computer communications, the protocol permits the exchange of ILL messages between bibliographic institutions that use different computers, systems, and communication services. Recently approved as a Draft International Standard by the International Standards Organization, the protocol is expected to become an International Standard in 1991. Implementations based on this standard are currently being developed by institutions and software vendors in North America and Europe.

The paper aims to propose a model that attempts to build an innovative common gateway compliant with RosettaNet Standards for the secure message exchange between electronic businesses in this age of internet economy.

The use of RosettaNet Standards is to achieve the effectiveness and efficiency of message exchange, and consequently gain mutual benefits by means of agile response for cross‐organizational co‐operation. This common message gateway is built and implemented as an organization's front‐end interface, but is seamlessly integrated with business's back‐end information systems for the message exchange with the business partners of the organization. The proposed common gateway service model provides organizations with low cost, high efficiency, high security of message exchange and transmission over the internet. A prototyping system is also built and tested in a local network devices manufacturing company with its suppliers to examine its feasibility and efficiency.

The result shows that the service model can help the company to achieve a new level of efficiency and effectiveness of streamlining data flow and creating a seamless link with its business partners in this era of internet economy.

The paper presents a common gateway service system for secure data exchange and transmission over the internet between business partners to build a value‐added supply network.

The upper three OSI layers support the communication requirements of applications, while the lower four layers provide reliable transmission of data. This article describes the lower four layers. First, though, a brief overview of the layered model is presented including a summary of the upper three layers. Then a description of the lower three layers is followed by a discussion of data communication standards associated with specific layers. Architectural concepts are then explored: hierarchy and abstraction within the layers, levels of dialogue, internetworking, end‐to‐end communication, analysis of layer four, and a discussion of connection‐oriented, connectionless, and message‐oriented protocols and applications. The article concludes with a comparison of OSI and the de facto industry protocols, TCP/IP, which are currently used within the Internet.

Presents the Message Assistant system (based on a HyperCard stack), designed by the authors to rank electronic mail messages in a priority order specified by the system user. Messages can be ranked according to the name of sender or even a key word in the message text.

The intelligent agent object (IAO) system is a multi‐paradigm development environment which can be used to create intelligent agent systems for manufacturing or other domains. The IAO system was developed from the rule‐based object (RBO) system which is a programming environment integrating both the rule‐based and object‐oriented paradigms. Propagation‐oriented programming, access‐oriented programming and group‐oriented programming are among the extensions included in the IAO system. Its most unusual contribution is the propagation‐oriented programming paradigm which is not found in most systems. A key application is the messenger inferencing structure which is a user‐extendable framework supporting multiple knowledge representation, meta‐inference control, and distributed inference. This allows the IAO system to go beyond predicate logic based production rule programming. New developments are also introduced for access‐oriented programming. The IAO system can be used to develop integrated manufacturing systems such as the prototype automated guided vehicle planning and control system, which is briefly described.

If EDI is to succeed to a similar degree as paper‐based systems then international harmonisation and standardisation must be achieved across all functional groups (banking, transport, insurance, customs) and industry sectors on message standard and structures. UN/EDIFACT is now the dominant body producing generic EDI messages for use in international trade. All functional areas have Message Development Groups but the main areas of success to date lie in deep sea transport, forwarding and customs functions. Message development needs to proceed rapidly in all functions before integrated EDI systems can be offered. In recognition of this, UN procedures are now in place to harmonise such message formats across all trade regions (ITIGG/IHG), industry sectors (MIST/IHG) and transport modes (MIST/ITIGG). The negotiability of the electronic Bill of Lading is also an issue which will be tested across industry sectors by Bolero Operations Ltd launch programme early in 1999.
