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.

The authors propose a simulation-based approach to the evaluation of a product's life cycle including recycling and reuse from the viewpoints of not only environmental impact but also the profitability of every company's business related to the life cycle. The flow of the material and money among the companies concerned with the life cycle are modeled and simulated. The simulation reveals whether each of the companies obtains a profit and how strong the environmental impact is. The simulation also shows the change in the environmental impact and profit with the passage of time. The modeling and simulation for a copier drum is presented as a validation example.

The increasing importance of a product's relationship and effects on the environment has prompted active research in demanufacturing systems. A disassembly process is a critically important part of a demanufacturing system. Its design and improvement is of great significance to achieve the best use of resources (labor, money and time). This paper addresses the disassembly line-balancing problem. An algorithm is developed to facilitate the disassembly line design and optimization, which dynamically configures a large system into many disassembly lines, based on system status and demand sources, guarantees the line balance and efficiency. An example is given to illustrate this methodology.
