The first volume gathers the papers dealing with systems level management and planning of manufacturing acitivities with topics on (1) management aspects and (2) manufacturing planning and control. The second volume concentrates on product and implementation related issues where papers are categorised into (1) product design and concurrent engineering, (2) factory automation, and (3) advanced manufacturing. With the growth on Internet-based businesses expanding since the last ICCIM conferences were held, and the trend as related to the manufacturing industry was anticipated and discussed in these past meetings, these two volumes will prove useful to establishing a track record of what latest technology is available today and will be available tomorrow.
