Warfare simulation Environment for Army Weapon and Equipment systems (WSAWES) provide a tactically robust environment for simulation experiments. The science and technology on complex Land systems simulation laboratory has now developed a tactical communication effects federate (TCEF) integrated with QualNet to model tactical communications systems and networks. TCEF interacts with WSAWES’s CGF that creates a constructive force-on-force simulation environment where communications are modeled by the TCEF and behaviors are modeled by the CGF. As the TCEF is already being integrated into distributed experiments in ghost mode, the TCEF services effort appears to be promising in meeting the stated goals, such as analysis for the connectivity and delay. © 2014 WIT Press.

Aiming at improving the target positioning accuracy, the formation configuration of anti-radiation loitering munitions is optimized. Firstly the time difference measuring error and positioning error of the loitering munitions are analyzed and the error propagation model is developed. Then the formation configuration design model is established based on the proposed time difference localization algorithm and the formation flying boundary conditions. Finally, considering the nonlinear features of optimization function for configuration optimization design, the genetic algorithm is introduced to obtain the optimal configuration. The simulation results show that, compared with the traditional formation configurations, the optimization design of configuration can acquire higher estimation accuracy of target position. Besides, the designed configuration has strong robustness. High accuracy estimations of target position can be obtained under a wide range of target position changes. © 2015 IEEE.

The suspension system with high performances is an important factor ensuring the tracked vehicle mobility and comfortable in different situations. Magneto rheological dampers, which are semi-active suspension equipment that use magneto rheological fluids to produce controllable force, can be used as smart actuators to reduce the vibrations of mechanical systems. An analytical study is performed in this article to examine the effectiveness of this type of actuator in suppressing the vibrations of a tracked vehicle suspension system. Based on the fluid mechanics theory, an amendment dynamic model of magneto rheological damper is derived. Considering the suspension characteristic and uncertainty of a magneto rheological damper, a variable universe fuzzy controller is designed to achieve a control of active variable damping. The results proved that the derived magneto rheological damper dynamic model is correct and indicated that the designed variable universe fuzzy controller could reduce the tracked vehicle vibration, which will further establish the basis of engineering application for a magneto rheological damper on semi-active suspension. © 2011 IEEE.

Prognostics and Health Management (PHM) has been researched on for recent years, and extensive studies have been done on hot topics into this field, such as diagnostics, prognostics, and decision making. However, how to evaluate PHM system architecture is still lacking. This is particularly important when designing avionics system equipped with PHM functions. We propose a general, time-variant architecture model that can simulate PHM system. Performance metrics are calculated to quantitatively evaluate the system architecture. This is useful to find differences of architectures in the earlier design stage in engineering. A case study is presented of the use of architecture modelling to show the effectiveness. And future works are discussed. © 2021 IEEE.

In this paper, an unified information description model ("UIDM" for short) is proposed to model information from multiple sources in the Information Grid uniformly. In the UIDM: 1) An unified information description language derived from the ODLI 3 is presented to describe information uniformly to resolve the information heterogeneity;2) A set of diagrammatized information modeling symbols are defined to model the information diagrammatically to illustrate the semantic relationships between information classes;3) An information capability model is advanced to model the capability of information from different information sources, based on which the high-performance global views for information sharing are to be constructed. © (2013) Trans Tech Publications, Switzerland.

Role-based approaches for operational tasks modeling and flexible decomposition

In order to realize the fact that operational tasks can be decomposed flexibly with new tasks random adding, role-based approaches for operational tasks model and the flexibility decomposition are proposed. Firstly, aiming at the shortcomings of previous task decomposition methods, operational role concepts are introduced to design a computing framework of task flexibility decomposition. Within the framework, task structure matrixes are constructed for tasks decomposition with the mapping relations of information interaction and action process among tasks. On basis of this, via giving operational decomposition granularity, a flexibility approach of operational task decomposition is put forward with three parts about task decomposition granularity adjustment, tasks module partition with different operational role patterns and task decomposition scheme evaluation. Finally, as an application case shown, it is validated that the proposed approaches for tasks modeling and decomposition are available. By comparing with previous decomposition approaches, the proposed approach, within three types of operational roles, has strong environmental adaptability and scheme diversity, which can restrain calculation complexity increment for realizing task flexible decomposition effectively. © 2016 Beijing Institute of Aerospace Information.

Role-based approaches for operational task-resource flexible matching model and algorithm

In order to solve the problem that previous relation researches in operational task-resource matching are hard to flexible computing for generating a new matching scheme from the existing scheme under the condition of operational tasks or resources adjusted in uncertainty cases, role-based approaches to operational task-resource flexible matching model and algorithm are proposed in the paper for flexible matching operational tasks with resources. Firstly, through introducing the concept of roles, the role-based calculation framework of operational task-resource flexible matching is constructed. Secondly, two aspect indexes about resource utilization ratio (RUR) and time utilization ratio (TUR) are given to reflect operational task-resource matching quality (TRMQ), which can be regarded as the objective function for modeling role-based operational task-resource flexible matching mathematical formulation. On the basis of this, the role-based artificial bee colony (RABC) algorithm, including five specific calculating operators, is put forward for solving the flexible matching problem with double encoding on operational tasks and resources by roles. Finally, via comparing with the previous methods in application cases, it can be validated that role-based model and proposed algorithm are more effective, which can be used to obtain a new incremental scheme from the existing matching scheme for adopting the operational tasks or resources adjustment. Moreover, there are flexible computation advantages of the approaches proposed in this paper to solve the problem about operational task-resource matching in large-scale. © 1990-2011 Beijing Institute of Aerospace Information.
