Radio frequency identifi cation (RFID) is a modern wireless data transmission and reception technique for applications including automatic identifi cation, asset track- ing and security surveillance. As barcodes and other means of identifi cation and asset tracking are inadequate for recent demands, RFID technology has attracted interest for applications such as logistics, supply chain Management, asset tracking and security access control.

Radio frequency identification (RFID) technology is witnessing a recent explosion of development in both industry and academia. A number of applications include supply chain Management, electronic payments, RFID passports, environmental monitoring and control, office access control, intelligent labels, target detection and tracking, port Management, food production control, animal identification, and so on. RFID is also an indispensable foundation to realize the pervasive computing paradigm—“Internet of things.” It is strongly believed that many more scenarios will be identified when the principles of RFID are thoroughly understood, cheap components available, and when RFID security is guaranteed.

It was the publisher’s idea that I write RFID in the Supply Chain: A Guide to Selection and Implementation . Not only am I editor of Enterprise Inte- gration System , Second Edition Handbook and author of The Complete Book of Middleware , I also had some innovative business process and project Management ideas on improving the effectiveness of integrating enterprise systems with information on product traceability, the scope of which has been widened by the RFID technology mandates.

Radio frequency identification (RFID) is a type of automatic identification systems which has gained popularity in recent years for being fast and reliable in keeping track of the individual objects. In RFID systems, contactless object identification is achieved using radio signals without the need for physical contact as the case with other existing identification technologies such as barcodes. Therefore, a huge number of items can be identified in a short amount of time with high reliability and low cost which makes the RFID technology very attractive for a wide range of applications such as supply chain Management, e-health, monitoring humans, pets, animals, and many other objects, toll control, and electrical tagging. Furthermore, RFID technology eliminates the human error and reduces the total cost of the products.

The present work, Advanced Process Engineering Control, is intended to be the continuation of the authors? Basic Process Engineering Control published by DeGruyter in 2014. It presents the main and conventional type control loops in process industries. Titles containing the concept of process engineering were deliberately chosen to suggest the inclusion, within the same approach, of processes other than the traditional ones. These come from outside the traditional fields of chemistry and petrochemistry: the sphere of pharmaceuticals, wastewater Management, water puri- fication, water reserve Management, construction material industry, food processing, household or automotive industries.

The main aim of this book is to present a unified, systematic description of basic and advanced problems, methods and algorithms of the modern con- trol theory considered as a foundation for the design of computer control and Management systems. The scope of the book differs considerably from the topics of classical traditional control theory mainly oriented to the needs of automatic control of technical devices and technological proc- esses. Taking into account a variety of new applications, the book presents a compact and uniform description containing traditional analysis and op- timization problems for control systems as well as control problems with non-probabilistic models of uncertainty, problems of learning, intelligent, knowledge-based and operation systems – important for applications in the control of manufacturing processes, in the project Management and in the control of computer systems.
