Aiming at the deficiency in the field of marine engineers training at present, an entire virtual training system for marine engineers has been designed and developed, which is composed of the full mission marine engine room simulator module and three-dimensional virtual marine engine room module, respectively aiming at cultivating the operating ability for marine engine room system and marine engine...
In order to make the service composition with lower consumption resource and reduce execution time of service composition process, this paper proposes a method to optimize service composition model based on analysis of service composition execution log information and optimization of its Petri net model, which includes three steps: firstly, the log information and extracting related data are collected;...
The business process modeling is the key to ensure the business runs correctly and flexibly. In the existing business process management system, the process-oriented has been widely adopted. With the traditional business process management system, process model is difficult to drive the system implementation and also unable to realize flexible change of this system. This article focuses on data, and...
The Internet of Things (IoT) has been widely applied in sensing systems, which connect various sensors and gather their information. Data fusion, which is to integrate multiple data representing the same real-world object into a consistent and accurate representation, is an important issue. Most of existing approaches of data fusion involve various analytical procedures whose high computational complexity...
To realize the autonomous adjustment function of the system parameters of the anti-jamming decision engine, a kind of swarm intelligence optimization algorithm- binary artificial bee colony (BABC) algorithm was used for reference. Decision method of communication anti- jamming based on binary artificial bee colony was proposed. In order to realize the autonomous choice of communication parameters,...
According to the theory of variable heat, the turbofan engine component level model was established and the model effective was verified. Because of the poor real-time of nonlinear model, the airborne composite engine model which can meet the requirements of precision and real-time was obtained by using block modeling method. The target function and the constraint conditions of multi variable turbofan...
