  1. 16. Towards a framework for enabling sustainable production systems: a life-cycle perspective

    Författare :Ilaria Giovanna Barletta; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy efficiency; discrete event simulation; e-waste; KPI; triple bottom line; decision support; manufacturing; sustainability;

    Sammanfattning : This thesis contributes to scientific knowledge by offering the foundation of a framework that helps stakeholders such as managers and engineers to enable sustainability over the entire lifecycle of the production system, from planning to re-use. In this thesis sustainability can be assessed through performance indicators and is understood through its triple bottom line of: economic, environmental and social sustainability. LÄS MER
