Research on Multi-Cooperative Combine-Integrated Scheduling Based on Improved NSGA-II Algorithm

International Journal of Agricultural and Environmental Information Systems (2021)

Li Ma Yidi Wang Meiqiong Ma Jiyun Bai

To promote the integration and optimal allocation of agricultural machinery resources to achieve the purpose of reducing cost and increasing efficiency, the scheduling problem of agricultural machinery in agricultural machinery cooperatives based on the trans-regional operation mode was studied in this paper, Considering multiple agricultural machinery points, multiple types, operation time windows, space distance and other factors, the multi-objective programming mathematical model with the lowest total cost of deployment, the highest service punctuality and the least use of harvester was established by applying path optimization and theory of job shop scheduling. NSGA-II was used to solve the model in this paper. According to the model features, this paper designed chromosome coding and the process of emergence, crossover and variation of initial population. Combined with the actual situation of rice harvesting in Wuchang City, the above scheduling theory was applied. The experimental results showed the validity and feasibility of the scheduling model and the algorithm.

Simulation and Optimization Study on Layout Planning of Plant Factory Based on WITNESS

International Journal of Security and Its Applications (2016)

Li Ma Meiqiong Ma Chao Ma Jingwen Deng Xingluo Liu

The emergence of plant factory has solved great restriction problem of natural environment in the traditional agriculture.Therefore, it has been the research concentrate on the facility agriculture in recent years.However, the reasonability of factory's production process and layout determines quality of the product, production efficiency and economic benefits.This paper took Wuchang Jingtian Plant Factory as an example, analyzed the production process and layout and provided a corresponding improvement scheme which was verified by the WITNESS simulation software.An optimal solution was determined from the evaluation index of production efficiency, busy rate, production cycle etc.. Besides, the simulation analysis of production cost before and after the improvement verified the improved plant factory operation is effective and feasible.This improvement scheme not only improved efficiency of production system of the plant factory, but also reduced the operating cost.

Research on Model of Combine Trans-regional Operation Scheduling

International Journal of Grid and Distributed Computing (2017)

Li Ma Meiqiong Ma Yanan Fan Yanjiao Zhang Hongjie Zhao

Unreasonable combine resource allocation has become one of the main factors influencing the economic benefits of trans-regional operation, so the scheduling strategy of combine trans-regional operation still needs to be further researched.On the basis of scheduling situation analysis of the order-oriented operation mode of agricultural machinery cooperation, this paper modelled the mathematical model of combine transregional operation scheduling with low cost and just in time as main targets.In modeling process, route optimization and workshop production scheduling theory were applied.Then, the idea of dynamic programming was used to carry out solution analysis of the model.Finally, this paper took an example of wheat trans-regional harvesting operation organized by an agricultural machinery cooperation of Hebei Province to verify the validity and feasibility of the model.

The Combination of Extension of Ant Colony Algorithm and Other Intelligent Algorithms

International Journal of Hybrid Information Technology (2015)

Li Ma Li Qianting Meiqiong Ma Jun Meng Ji-yun Bai

The extension of ant colony algorithm was proposed by Dorigo, the founder of ant colony algorithm, which is the latest ant colony algorithm for solving a continuous space optimization problem. Considering the blindness of man-made choice of initial solution and initial parameters of the algorithm, and according to the algorithm converging slowly and easily falling into local optimum, this paper has provided improvement strategy for this optimization. It has introduced quantum computing and genetic algorithm, chaos optimization to carry out combination and comparison, and it has carried out improvement on the weight internally solved by memory in the algorithm. The effectiveness of various combined algorithms was determined through the optimization of numerous multi-dimensional continuous functions.
