Since products during the use stage may experience very different conditions, their external and internal status can vary significantly. These products, when coming to a demanufacturing facility, are often associated with incomplete/imprecise, sometime wrong, information so that the demanufacturing processes have to be decided dynamically based on the products' specific status. This paper presents a Fuzzy Reasoning Petri net model to represent such a product with uncertainty and its related demanufacturing decision rules. Based on this model, a formal reasoning algorithm using the operators in max-algebra is proposed to perform fuzzy reasoning. Using the proposed model, the multi-criterion demanufacturing rules can be considered in the parallel way to make the decision automatically, which makes the real time disassembly process decision possible. At last, an example is used to specify the application of the proposed method.
