  • Publication number: 20250147489
    Abstract: The present disclosure belongs to the field of flexible job shop scheduling, and relates to a dual-effect scheduling method for heterogeneous robots in a flexible job shop. In a case of strong coupling of processing and transferring, this method comprehensively considers such constraints on selection of flexible manufacturing cells (FMCs), transferring time by automatic guided vehicles (AGVs) and processing resource waste, and improves encoding schemes and genetic operators with order completion time and minimization of resource consumption as evaluation criteria. Additionally, this method can fully apply environmental characteristics of job shop to scheduling design, and automatically design more precise scheduling schemes, overcoming the deficiencies of slow response and prone to local optimal solutions existing in conventional scheduling schemes, and ensuring efficient and green operation.

  • Patent number: 12253861
    Abstract: A multi-robot collaboration method in a flexible hardware production workshop is provided, by which allocation of workpiece machining tasks and transfer of workpieces in different workstations can be achieved and meanwhile relatively high calculation cost is avoided. According to the method, a distributed collaboration method is fully used, and in allusion to the current technical condition, the allocation of the workpiece machining tasks and the transfer of the workpieces in different workstations can be achieved and meanwhile the relatively high calculation cost is avoided. A multi-AGV path conflict eliminating method is used for avoiding possible collision of AGVs during movement. A centralized intervention and adjustment method is used for discovering and predicting system conflicts and failure problems and making timely dispatching and adjustment so as to improve the automation level and the flexibility level of a hardware workshop.

  • Patent number: 12161685
    Abstract: A multi-efficacy traditional Chinese medicine compound composition and application thereof in pharmaceutical preparations are disclosed. The traditional Chinese medicine extracts are combined with the glucosamine, the collagen and the chondroitin sulfate, so that the multi-efficacy traditional Chinese medicine compound composition is prepared. The traditional Chinese medicine compound composition starts from improving the health of bone and joint and accompanying cardiovascular disease, selects the medicinal materials, and optimizes the extraction process of the traditional Chinese medicine for the diseases dominated by degenerative osteoarthritis. The disclosure has the efficacious of improving the symptoms of degenerative osteoarthritis, reducing blood pressure, improving the symptoms with osteoporosis, improving the symptoms with cardiovascular disease, improving the symptoms with urinary system disease, etc.

  • Patent number: 12099346
    Abstract: Disclosed is a large-scale dynamic double-effect scheduling method for a flexible job shop based on genetic programming (GP). In a GP implementation process of the present disclosure, in addition to features related to workpieces, processing robots and automated guided vehicles (AGVs), such as processing time of working procedures and buffer area waiting time, features of a ratio of processing time to transfer time and a ratio of processing energy consumption to transfer energy consumption are also added in a terminal set to cause job shop environment features to be more comprehensively applied to a scheduling rule design, thereby automatically designing a more consistent and accurate scheduling rule. A double-effect scheduling rule of the present disclosure overcomes the shortcomings of slow convergence speed, difficulty in rapid corresponding changes and unfit scheduling rules, and can quickly produce a more efficient and energy-saving production scheduling scheme.

  • Publication number: 20220087926
    Abstract: A compound composition with anti-oxidation and anti-aging effects and preparation method and application thereof we disclosed. 5-8 kinds of traditional Chinese medicine extracts from separate extraction of Panax ginseng C. A. Meyer, Poria, Rehmannia glutinosa, Cistanche deserticola Ma, Salviae Miltiorrhizae, Codonopsis Radix, Persicae Semen and Ophiopogon japonicus (Linn.f.) Ker-Gawl. are compounded with chitooligosaccharide to prepare the compound composition with anti-oxidation and anti-aging effects. The compound composition has no toxic side effects, is easy to be absorbed, and can be used for delaying aging, repairing DNA damage and anti-oxidation damage, and can also reduce the risk of geriatric diseases. Moreover, the compound composition can be used as a raw material of dietary supplement or health food to improve telomerase content and delay aging. Therefore, the compound composition is suitable for promotion and application.

  • Patent number: 6613051
    Abstract: The present invention relates to an internal anterior transpedicular fixation system and a method for rigidly fixing the spine anteriorly at the level above and below a thoracolumbar burst fracture or tumor. The internal anterior transpedicular fixation system has a support member defining a plurality of engaging portions thereon. At least two of the engaging portions are spaced longitudinally from each other and adapted to span at least one verteba. At least two of the engaging portions are spaced laterally from each other and adapted to span a lateral distance of the verteba. A plurality of fixation elements are provided to mount the engaging portions onto the verteba. Thereby, the support member is restrained from rotational or translational movement relative to the verteba.
