Manufacturing a product is t difficult, the difficulty consists in manufacturing a product of high quality, at a low cost and rapidly. Drastic techlogical advances are changing global markets very rapidly. In such conditions the ability to compete successfully must be based on invative ideas and new products which has to be of high quality yet low in price. One way to achieve these objecti- ves would be through massive investments in research of computer based techlogy and by applying the approaches presented in this book. The First International Conference on Advanced Manufacturing Systems and Techlogy AMST87 was held in Opatija (Croatia) in October 1987. The Second International Conference on Advanced Manufacturing Systems and Techlogy AMSV90 was held in Trento (Italy) in lune 1990. The Third, Fourth, Fifth and Sixth Conferences on Advanced Manufacturing Systems and Techlogy were all held in Udine (Italy) as follows: AMST93 in April 1993, AMST96 in September 1996, AMST99 in June 1999 and AMST02 in June 2002.
