The state space model of remanufacturing carbon footprint for low-carbon

摘要

Energy conservation is the core value of remanufacturing engineering. This paper constructs a state space model of remanufacturing carbon footprint for low-carbon to describe the relationship of state variables (parts quality, accuracy, etc.), input variables (remanufacturing operations) and output variables (carbon emissions). A transfer function of carbon footprint in remanufacturing process is established. Because of the uncertainty of remanufacturing process, we studied the state estimation of observation vector in remanufacturing process based on the least squares method. Finally, an example of two remanufacturing process crankshaft machining path verified the effectiveness and feasibility of the model. This paper describes the remanufacturing process with carbon footprint, which is possible to quantitatively evaluate the advantages of remanufacturing machining technology, and it provides support for manufacturing process optimization.
