Just on the operational side of it, efforts of thousands of people across hundreds of organizations need\r\nto be coordinated. Numerous tasks of varying complexity and nature, from scientific to construction, need to be\r\naccomplished within limited mission time frames. Resources need to be carefully managed and contingencies worked out, often on a very short notice. From the beginning of the NASA space program, planning has been done by large teams of domain experts working\r\nmonths, sometimes years, to put together a single mission. This approach, while proven very reliable up to now, is becoming increasingly harder to sustain. Elevated levels of\r\nNASA space activities, from deployment of the new Crew\r\nExploration Vehicle (CEV) and completion of the\r\nInternational Space Station (ISS), to the planned lunar\r\nmissions and permanent lunar bases, will put an even\r\ngreater strain on this largely manual process. While several\r\nattempts to automate it have been made in the past, none\r\nhave fully succeeded. In this paper we describe the current\r\nNASA planning methods, outline their advantages and\r\ndisadvantages, discuss the planning challenges of upcoming\r\nmissions and propose a distributed planning/scheduling\r\nframework (CMMD) aimed at unifying and optimizing the\r\nplanning effort. CMMD will not attempt to make the\r\nprocess completely automated, but rather serve in a decision\r\nsupport capacity for human managers and planners. It will\r\nhelp manage information gathering, creation of partial and\r\nconsolidated schedules, inter-team negotiations,\r\ncontingencies investigation, and rapid re-planning when the\r\nsituation demands it. The first area of CMMD application\r\nwill be planning for Extravehicular Activities (EVA) and\r\nassociated logistics. Other potential applications, not only\r\nin the space flight domain, and future research efforts will\r\nbe discussed as well.", "distribution": [{"@type": "dcat:Distribution", "description": "AIAA_SS_2006_CMMD.pdf", "downloadURL": "https://c3.nasa.gov/dashlink/static/media/publication/AIAA_SS_2006_CMMD.pdf", "format": "PDF", "mediaType": "application/pdf", "title": "AIAA_SS_2006_CMMD.pdf"}], "identifier": "DASHLINK_388", "issued": "2011-06-07", "keyword": ["ames", "dashlink", "nasa"], "landingPage": "https://c3.nasa.gov/dashlink/resources/388/", "modified": "2025-04-01", "programCode": ["026:029"], "publisher": {"@type": "org:Organization", "name": "Dashlink"}, "title": "Planning to Explore: Using a Coordinated Multisource Infrastructure to Overcome Present and Future Space Flight Planning Challenges"}
