However, previous works on organization search have mainly focused on the single-chain hierarchical organization in which all decisions are regarded as homogeneous. The heterogeneity and the interdependency between technical decisions and management decisions have been neglected. A two-chain hierarchical organization structure mapped from a real complex project is constructed. Then, a discrete decision model for a Liang Zong two-chain hierarchical organization in an NK model framework is proposed. This model proves that this kind of organization structure can reduce the search space by a large amount and that the search process should reach a final stable state more quickly. For a more complicated decision mechanism, a multi-agent simulation based on the above NK model is used to explore the effect of the two-chain organization structure on the speed, stability, and performance of the search process. The results provide three insights into how, compared with the single-chain hierarchical organization, the two-chain organization can improve the search process: it can reduce the number of iterations efficiently; the search is more stable because the search space is a smoother hill-like fitness landscape; in general, the search performance can be improved.However, when the organization structure is very complicated, the performance of a two-chain organization is inferior to that of a single-chain organization. These findings about the efficiency of the unique Chinese-style organization structure can be used to guide organization design for complex projects.展开更多

The model based on the multi-stage influence diagram graphically describes the elements of decision process, and contains a point-mass model for the dynamics of an aircraft and takes into account the decision maker's preferences under uncertain conditions. Considering an active opponent, the opponent's maneuvers can be modeled stochastically. The solution of multistage influence diagram can be obtained by converting the multistage influence diagram into a two-level optimization problem. The simulation results show the model is effective.展开更多

The application is important in the detection and epidemic prevention of CoronaVirus Disease 2019 (COVID-19) to alleviate the large-scale negative impact of individuals suffering from pneumoniaowing to COVID-19. In this method, the idea of a hierarchical decision network is used to consider the stronginfectious characteristics of the COVID-19, which is followed by processing the robot behavior constraint condition.The visual navigation and positioning method using a single-arm robot for sampling is also planned, whichconsiders the operation characteristics of medical staff. In the decision network, the risk factor for potentialcontact infection caused by swab sampling operations is established to avoid the spread among personnel. A robotvisual servo control with artificial intelligence characteristics is developed to achieve a stable and safe nasal swabsampling operation. Experiments demonstrate that the proposed method can achieve good vision positioning forthe robots and provide technical support for managing new major public health situations.展开更多
