Abstract
This project had two goals. First, we sought to explore the effects of manning levels on the operational performance of the LCS. Three models of the core enlisted crewmembers of the LCS (FREEDOM variant) were developed. Crewmembers were involved in planned activities (e.g., watch, planned maintenance, sleep), and unplanned events (e.g., corrective maintenance, drills). Results showed that watchstanding crewmembers worked over 14 hours of duty per day with less than 6.5 hours of sleep per night. Enginemen, gas turbine system technicians, and electrician’s mates had the highest workload and slept the least. We also explored the operational effect of an “extreme” unplanned event on the crew. Results suggested that an “extreme” event causes sustained wakefulness (i.e., approximately 30 crewmembers did not sleep for close to 40 hours during the event). The second goal of this project was to assess the appropriate manning levels of the Sea Duty Unit Identification Code (UIC) at LCSRON ONE, i.e., the crewmembers responding as temporary replacements to crews and detachments that suffer unplanned losses. Results show a tradeoff that occurs as billets are added to the Sea Duty UIC. The more sailors assigned to the Sea Duty UIC, the greater the probability one will be available to respond to an emergent request for temporary assignment, and the lower the expected time crews spend waiting for temporary replacements. However, as more sailors are added to the Sea Duty UIC the time those sailors spend in an unassigned status and simply waiting for work also increases.
