• W2137037461 abstract "Despite wide recognition that lunar bases are to be engaged in significant industrial operations, such as resource extraction and propellant production, to date, authors discussing space basing have not delineated location and layout design considerations as found in the processing plant and mining literature discussed. This paucity may be due to several factors. The body of knowledge of planetary basing is not as rich in empirical or experiential evidence nor as lengthy as for mining and process plants. Additionally, most considerations of lunar or martian bases have been more oriented to small temporary science and exploration outposts rather than viewing the bases as production systems. Consequently, there has been little attention to the production processes and the optimization of base layout for operational productivity, efficiency, safety, and cost. The purpose of this paper is to report preliminary efforts to assess potential siting issues for lunar bases to address this shortfall. This study attempted to frame the optimization problem posed by the set of variables and constraints and the relationships among those variables relative to operations in the lunar environment. Although a literature survey examined candidate optimization approaches, there was no attempt in this effort to select an approach or to develop an optimization scheme. The results suggest that while terrestrial analogs of lunar sites are insufficiently developed industrially to offer much insight, there is a substantial volume of literature concerning terrestrial mining and process plants to offer excellent analogs. In considering the terrestrial processing plant and mining operation as analogs for future planetary industrial operations and projecting to the lunar surface, several conclusions may be drawn. First, in the context of an optimization problem, the analogs suggest that several objective functions may be relevant. Among these is an emphasis on safety, most significantly represented by EVA safety, that should be reflected in the problem objective statement. Such statements influence layout by maximizing adjacencies between human-attended units, where possible, and by requiring pressurized and shielded passageways where not. A preliminary list of thirteen factors is offered for consideration for lunar base layout design. Additionally, common manufacturing facility layout concerns and optimization approaches are available and appear promising. A simple example of the application of a common layout methodology, i.e., Systematic Layout Planning, is developed for a notional lunar industrial site. This simplistic, well-used, graphical method can offer a better rationalized approach than seen in the literature to date. Further, this approach may be completely satisfactory for most lunar production systems envisioned in the near-term." @default.
