1A dual population multi-operator genetic algorithm for flight deck operations scheduling problem显示文摘It is of great significance to carry out effective scheduling for the carrier-based aircraft flight deck operations.In this paper,the precedence constraints and resource constraints in flight deck operations are analyzed,then the model of the multi-aircraft integrated scheduling problem with transfer times(MAISPTT)is established.A dual population multi-operator genetic algorithm(DPMOGA)is proposed for solving the problem.In the algorithm,the dual population structure and random-key encoding modified by starting/ending time of operations are adopted,and multiple genetic operators are self-adaptively used to obtain better encodings.In order to conduct the mapping from encodings to feasible schedules,serial and parallel scheduling generation scheme-based decoding operators,each of which adopts different justified mechanisms in two separated populations,are introduced.The superiority of the DPMOGA is verified by simulation experiments.CUI Rongwei HAN Wei SU Xichao LIANG Hongyu LI Zhengyang 2021Journal of Systems Engineering and Electronics2021,32,2:3
2Optimization of fixed aviation support resource station configuration for aircraft carrier based on aircraft dispatch mission scheduling显示文摘Before the dispatch of the carrier-based aircraft,a series of pre-flight preparation operations need to be completed on the flight deck.Flight deck fixed aviation support resource station configuration has an important impact on operation efficiency and sortie rate.However,the resource station configuration is determined during the aircraft carrier design phase and is rarely modified as required,which may not be suitable for some pre-flight preparation missions.In order to solve the above defects,the joint optimization of flight deck resource station configuration and aircraft carrier pre-flight preparation scheduling is studied in this paper,which is formulated as a two-tier optimization decision-making framework.An improved variable neighborhood search algorithm with four original neighborhood structures is presented.Dispatch mission experiment and algorithm performance comparison experiment are carried out in the computational experiment section.The correlation between the pre-flight preparation time(makespan)and flight deck cabin occupancy percentage is given,and advantages of the proposed algorithm in solving the mathematical model are verified.Yujie LIU Wei HAN Xichao SU Rongwei CUI 2023Chinese Journal of Aeronautics2023,36,2:1
3Effects of homogenization and heat treatment on fatty acids in milk from five dairy species显示文摘Milk fatty acids significantly contribute to human nutrition and clinical health.However,previous evidence for changes in the fatty acid profiles of different dairy species following homogenization and heat treatment is lacking.Here,changes in fat globule particle size and fatty acids in samples of Holstein,goat,buffalo,yak,and camel milk following homogenization(20 MPa)and heat treatment(63℃for 30 min and 90℃for 15 min)were investigated using a laser particle sizer and gas chromatography approach.The results indicated that the milk fat globule particle size of all studied dairy species significantly decreased after homogenization and heat treatment,in which there was no difference.The fatty acid composition of C10:0 and medium-chain fatty acid in goat milk,Ci8:0 and long-chain fatty acid in camel milk,and C16:0 in buffalo and yak milk served as the characteristic traits of these milks.Changes in the relative contents of several fatty acids(C4:0,C10:0,C16:0,C18:0,C18:1n9c,and C18:3n3)were dependent on homogenization,heat treatment,and the type of dairy species.In particular,C18:3n3 significantly decreased in goat and camel milk after homogenization and heat treatment.These findings provide new insights into how homogenization and heat treatment affect the fatty acid profile and can be used to further improve the heat treatment of milk from minor dairy species.Rongbo Fani Runjia Shi Zhongyuan Ji Qijing Du Jun Wang Hongning Jiang Rongwei Han Yongxin Yang 2023Food Quality and Safety2023,7,1:0
