    Sammanfattning : In the recent years, radio-frequency identification (RFID) technology has been widely integrated into modern society applications, ranging from barcode successor to retail supply chain, remote monitoring, detection and healthcare, for instance. In general, an RFID tag or transponder is composed of an antenna and an application-specific integrated circuit chip. LÄS MER

  5. 14. The green engineer as an enabler of life-cycle management in manufacturing: models and practices

    Författare :Birger Löfgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; discrete-event simulation; life-cycle assessment; operation management; decision making; practice studies; environmental management;

    Sammanfattning : The last 20 years corporate environmental management has developed from pollution control and emission prevention, to include a greater responsibility for indirect environmental issues along the whole product life cycle. This thesis aims at providing a better understanding of how such environmental life-cycle management can be applied on manufacturing processes. LÄS MER
