Moreover, it provides plug-and-play capability through standardization of the transducer interfaces. This paper is on the creation of a test suite that specifies tests such as conformance and functionality. Test cases have been developed to check the communication between the tester NCAP and the NCAP under test, based on IEEE 1451.

This paper builds upon our previous work to address uncertainty management in disassembly. By taking advantage of fuzzy logic and the formalism of Petri nets, this paper proposes a Fuzzy Disassembly Petri Net (F-DPN) model to mathematically represent uncertain product/component conditions. An adaptive fuzzy system with an iterative learning mechanism is then designed to dynamically estimate their impact on a disassembly process. Finding the disassembly path of a discarded product with the highest economic value and prediction confidence is accomplished through a recursive computation. The proposed method is exemplified and validated through the disassembly of a batch of telephone handsets.

Since the demand for new solutions to economically deal with such outdated products begun to rise, the disassembly line has emerged as a viable solution to this problem.
