Disassembly planning is an effective way to recycle valuable parts or materials from end-of-life products. Due to the parts are easily affected by some unpredictable factors in the real disassembly process (such as defective parts and human factors), there may be failure operations that cannot successfully disassemble the corresponding parts in the real world. Therefore, a partial disassembly sequence planning with uncertainty is proposed in the paper, where the success rates of disassembly operations are formulated to model an expected profit-based disassembly sequence planning. Also, a general variable neighborhood search algorithm is developed to optimize the mathematical model. Meanwhile, in the approach, a heuristic procedure is utilized to obtain a high-quality initial solution, and four different neighborhood structures are introduced to improve the disassembly solution. Its superiority and effectiveness are well illustrated by two case studies and comparison with two existing metaheuristics, i.e., artificial bee colony algorithm and genetic algorithm.
Abstract-Shadowboxing is an excellent kind of boxing in Chinese Wushu, and is widely known in the world for its unique movement styles and features. Shadowboxing is not just a kind of sport, but also an art and even a kind of culture. Shadowboxing practicers both inside and outside China have a deeper understanding and knowledge of Chinese classic culture by learning and practising shadowboxing. In this paper, shadowboxing is studied from the angle of art, and the art features of shadowboxing are interpreted so that the world may know the connotation of shadowboxing more deeply, the taste about shadowboxing is improved, the world may understand the pursuit of art of Chinese classic culture better, and Chinese Wushu and Chinese classic culture may be widely promoted better.
