An event chain notification and management system using SMS

This paper describes the design of a framework and implementation of a testbed of an event propagation and management system. These events are generated by equipment or machines in a plant. Event states are modeled using statecharts and colored Petri nets, which were used also for simulating the proposed system. In our lab test a small network is set-up, which represents a federated control system consisting of (simulated) equipment generating events, a server brokering between event producers and consumers and mobile phones, which are the consumer of events and that are used to respond to events using SMS messaging. The testbed simulates equipment or machines in a factory or plant, which under normal circumstances operate stand-alone or with minimal supervision of an operator. In case of failure, these machines require immediate response from a service engineer, as the operation of the machine within the factory or plant is mission-critical and thus demands a minimum downtime (as will be the case when there are abnormalities, failures or events). The framework was successfully tested and has been found to be a viable and affordable solution for efficient event management.
