Modeling and simulation for additive manufacturing (AM) is commonly used in industry. Nevertheless, a central issue remaining is the integration of different models focusing on different objectives and targeting different levels of details. The objective of this work is to increase the prediction capability of characteristics and performances of additively manufactured parts and to co-design parts and processes. The paper contributes to this field of research by integrating part's performance model and additive technology process model into a single early integrated model. The paper uses the dimensional analysis conceptual modeling (DACM) framework in an AM perspective to generate causal graphs integrating the AM equipment and the part to be printed. DACM offers the possibility of integrating existing knowledge in the model. The framework supported by a computer tool produces a set of governing equations representing the relationships among the influencing variables of the integrated model. The systematic identification of the weaknesses and contradictions in the system and qualitative simulation of the system are some of the potential uses of the model. Ultimately, it is a way to create better designs of machines and parts, to control and qualify the manufacturing process, and to control three-dimensional (3D) printing processes. The DACM framework is tested on two cases of a 3D printer using the fused filament fabrication (FFF) powder bed fusion. The analysis, applied to the global system formed of the 3D printer and the part, illustrates the existence of contradictions. The analysis supports the early redesign of both parts and AM process (equipment) and later optimization of the control parameters.

Functional modeling is an analytical approach to design problems that is widely taught in certain academic communities but not often used by practitioners. This approach can be applied in multiple ways to formalize the understanding of the systems, to support the synthesis of the design in the development of a new product, or to support the analysis and improvement of existing systems incrementally. The type of usage depends on the objectives that are targeted. The objectives can be categorized into two key groups: discovering a totally new solution, or improving an existing one. This article proposes to use the functional modeling approach to achieve three goals: to support the representation of physics-based reasoning, to use this physics-based reasoning to assess design options, and finally to support innovative ideation. The exemplification of the function-based approach is presented via a case study of a glue gun proposed for this Special Issue. A reverse engineering approach is applied, and the authors seek an incremental improvement of the solution. As the physics-based reasoning model presented in this article is heavily dependent on the quality of the functional model, the authors propose a general approach to limit the interpretability of the functional representations by mapping the functional vocabulary with elementary structural blocks derived from bond graph theory. The physics-based reasoning approach is supported by a mathematical framework that is summarized in the article. The physics-based reasoning model is used for discovering the limitations of solutions in the form of internal contradictions and guiding the design ideation effort.

For the unbalanced developments of space _________________________________________ technology and aerospace industry, space-based information system tends to be highly fragmented into subsystems of different application functions, such as reconnaissance & surveillance systems, data transmission systems, guidance & positioning system and so on [4].…”

On the basis of integrating each subsystem in topological structure, implementation function, operation mode and institutional mechanism, this paper has established a comprehensive service system which could manage various heterogeneous resources and handle kinds of complex missions within the architecture to carry out the research of the resource scheduling architecture for service-oriented space-based information system. Originally, this paper analyzes the characteristics of space-based information system from two aspects of diversity and dynamics. Based on the research, this paper studies the organizational structure of resource scheduling of space-based information system to realize the unified management and scheduling of service-oriented diversification resources following the sequence from resources to missions. Afterwards, this paper has proposed a resource scheduling mode for the service-oriented space-based information system to realize the mapping from resources to missions, and it also has used that mode to block differentiated user requirements and the dynamic changes of the system. In the end, the paper has put forward the implementation plan of the resource scheduling for service-oriented space-based information system, and it also provides a reference for the next construction of the space-based information system.
