“…The space station is one of the most complex aerospace phased-mission systems, with a structure that includes several associated modules and a configuration process involving dozens of manned flight and cargo flight missions [1][2][3]. Due to the structure's dynamic changes, reliability assessment is the main technical means to judge configuration effectiveness [4].…”

A space station is a typical phased-mission system, and assessing its reliability during its configuration is an important engineering action. Traditional methods usually require extensive data to carry out a layered reliability assessment from components to the system. These methods suffer from lack of sufficient test data, and the assessment process becomes very difficult, especially in the early stage of the configuration. This paper proposes a reliability assessment method for the space station configuration mission, using multi-layer and multi-type risks. Firstly, the risk layer and the risk type for the space station configuration are defined and identified. Then, the key configuration risks are identified comprehensively, considering their occurrence likelihood and consequence severity. High load risks are identified through risk propagation feature analysis. Finally, the configuration reliability model is built and the state probabilities are computed, based on the probabilistic risk propagation assessment (PRPA) method using the assessment probability data. Two issues are addressed in this paper: (1) how to build the configuration reliability model with three layers and four types of risks in the early stage of the configuration; (2) how to quantitatively assess the configuration mission reliability using data from the existing operational database and data describing the propagation features. The proposed method could be a useful tool for the complex aerospace system reliability assessment in the early stage.

“…Applied throughout the design phases of the development lifecycle, M&S may show up in different applications such as computer-aided design (CAD) and computer-aided engineering (CAE) models for sizing system elements or in simulators of equipment, subsystems, and even the entire spacecraft together with the space environment and ground stations (Hua-Yi, 2014; Mendoza-Bárcenas et al, 2014; Triharjanto et al, 2015; Wang et al, 2017).…”

“…While M&S is widely used during pre-phase A for individual disciplines, and spacecraft simulators for conceptual studies have already been developed (Cyril, 1998; Liceaga and Troutman, 1997; Wang et al, 2017), to the best knowledge of the authors, a systemic dynamic simulation of the entire mission concept seems to be less attempted. In fact, we could find in literature only one paper (Kranz et al, 2014) that considered such approach, even though in this work the focus is on a generic workbench for integrating simulation tools of individual disciplines.…”

Nowadays, it is practically impossible to develop a complex project without the assistance of a comprehensive set of modeling and simulation tools. In space engineering, they are used throughout the product design cycle, from component up to the system level. In conceptual, pre-phase A studies of a space mission, these tools are essential to explore more broadly the design space, in the search for suitable candidate system solutions for the mission. They are also of prime importance in helping to reduce the design time in integrated concurrent design environments. Here, a multidisciplinary tool for concept of operation simulation, developed to be used in that kind of environments, is presented. FOrPlan has the main purpose of performing functional simulations of the satellite and associated ground segments, providing a dynamic verification of the mission designed operational concept. Through the use of suitable graphical interfaces, key parameters of the mission functional scenarios can be presented to the design team and other mission stakeholders, allowing them also a better understanding of the mission operational concept. The simulator presents high flexibility such that it can be quickly customized to different mission scenarios. It has been used successfully at the Space Missions Integrated Design Center (CPRIME) of the Brazilian National Institute for Space Research. In this article, the structure of FOrPlan is presented, and its main features highlighted through results of concept of operation simulations performed for a scientific space mission study that was carried out recently at CPRIME.
