Abstract: The present studies on the algorithm of the consensus in a group decision are a general foundation on the hypothesis of the standardization and homogeneity. It tends to the general objects and hides the complexity of the decision-making among special groups. For low molecular subjects, it is very weak for the decision-making in cooperation in terms of the trust foundation. The capacity of the adjustment to the conflict is insufficient and the effective feedback of the communication is also insufficient. Based on the traditional method of the group decision, the model of a trust consensus acquisition for the low-molecular decision-makers is constructed. Firstly, differences among the subjective and objective trust, evolution of the inter-relationship, changes in the weight and trust consensus under discontinuous trust differences among the low-molecular decision-makers are focused on. After introducing the concept of the trust element to master the subjective and objective connotation of the trust element among the low-molecular decision-maker, it is based on the cosine similarity to study the consistency of the subjective and objective trust to use the algorithm of the multi-trust dynamic transformation, which ca demonstrate the subjective and objective trust range in the process of the subjective interaction. Then the discontinuous trust function is utilized and use the hesitant obscurity Einstein is used to seduce the ordered weighted set operator. And then it needs to calculate and gather of the discontinuous trust and the improved OWA operator should experience the subjective trust and weight transmission. It can describe the levels of the trust among the subjects and the evolution of the cooperation trend. Finally, the coordinated acquisition of the trust elements is becoming among the low-molecular decision-makers. The comparison shows that improved model of the coordinated acquisition of the trust elements is superior to the tradition method in terms of the speed of the acquisition and the consensus levels, which overcomes the vagueness of the characteristics of the traditional model, the lacking in comprehensive analysis of the content and the insufficient feedback information. It can be better to establish trust basis during the process of the decision-making among the low-molecular subjects, decrease the conflict and increase the effect of the inter-communication. This paper tends to explain the connotation of the trust element among the decision-makers and the norms of the transmission, which make further development in terms of the general premise and the research scope. It can offer a new type for dynamic acquisition of the trust consensus in an uncertain condition. It is a theoretical and empirical study.
