This document summarizes a thesis presentation on designing an expert system for monitoring and managing web-based industrial applications. The presentation covers problem statements and objectives, a case study of an industrial production line, designing a web service monitoring system using XML schemas, implementing the expert management system using a knowledge base and rules engine, and conclusions and future work. The goal is to integrate old automation technologies with modern web service and information technologies using a smart monitoring and management system.

TTE-7906, Machine Automation Thesis Presentation Seminar Problem statement and work objective • Integrating the old automation technologies which exists in shop floor to the current factory information technology, specifically web service technology without destroying the shop floor infra-structure or interrupt the production process • Processing the information obtained from web services using a smart management system Purposed solution and thesis work • Adding a new controller which compatible with the old technologies and able to implement the web service technology • Applying the recommendation of ISA-95 model at layer two and three • Designing generic XML events based on analogy with CAMX standard to monitor the system in layer two of ISA-95 model • Defining the convenient key product indicators – KPIs – in a generic way to fit most of similar production lines to our case study • Translate those KPIs in form of drool software rules, for management of the system in layer three of ISA-95 model 3

- 5. TTE-7906, Machine Automation Thesis Presentation Seminar Designing of a web service monitoring system A web service is a software system designed to support interoperable machine-to-machine interaction over a network. It has an interface described in a machine-processable format (specifically WSDL). Other systems interact with the Web service in a manner prescribed by its description using SOAP messages, typically conveyed using HTTP with an XML serialization in conjunction with other Web-related standards XML web service Why example 1- Self-contained application and independency of the language of the operating system 2- Self-describing application 3- Encapsulated, modularity, integrity and expandability 4- Interoperability 5- Discoverability - Dynamic language 6- Open source and standard language 5

TTE-7906, Machine Automation Thesis Presentation Seminar Designing of the WSDL document Types a container for all the data type using standard way such as XML schema Message an abstract, typed definition of the data being communicated Operation an abstract description of an action supported by the service Port Type an abstract set of operations supported by one or more endpoints Binding a concrete protocol and data format specification for a particular port type Port a single endpoint defined as a combination of a binding and a network address Service a collection of related endpoints Implementation of web services on our case study The S1000 is a smart RTU device which offers process control capabilities, as well as a Web-based Human-Machine Interface (HMI), support for WebServices, 7

TTE-7906, Machine Automation Thesis Presentation Seminar Designing of an expert management system Expert Expert system shell Knowledge Knowledge Reasoning User Base Base engine Interface User Expert Systems (ES): A computer program that contains a knowledge base and a set of algorithms or rules that infer new facts from knowledge and from incoming data. An expert system is an artificial intelligence application that uses a knowledge base of human expertise to aid in solving problems. The degree of problem solving is based on the quality of the data and rules obtained from the human expert. Expert systems are designed to perform at a human expert level. 9

TTE-7906, Machine Automation Thesis Presentation Seminar Conclusions • ISA 95 model can fit modern automation system designs • CAMx standard is meant to be for exchange data among manufacturing equipment and applications on the electronics manufacturing floor. However still can be used as a reference for creating generic XML schemas for other applications • Web service technology is suitable technology to upgrade the old existing automation system • Drools is a suitable rule engine for building an expert system for a web based industrial system Future work • Providing more graphical user interface (GUI) for user for both monitoring and management system • Tasting our management system with the XML messages coming from the machines not from Fiddler • Searching for other generic KPIs for the other elements within the project and translate them to drool rules • Expand the rules due to the new experiences of the case study 12
