Abstract
In support of the next generation aircraft carrier, the CVN 21 class, Northrop Grumman Newport News (NGNN) has developed a long term strategic plan to modernize their shipyard. In this plan, several new facility construction projects have been proposed that will increase the level of complex outfitting and assembly that typically occurs throughout the ship construction cycle. These new facilities provide controlled environments that will enable schedule and cost improvements for work that traditionally was performed outdoors. One facility in the strategic plan is a new Covered Modular Outfitting Facility (CMOF). The CMOF will be a covered, temperature controlled facility located under the large gantry dock crane which will be used primarily to assemble high-value-added products. NGNN believes that new facilities similar to the CMOF will increase productivity in several ways: decrease lost work days due to weather, reduce rework due to damage, and increase the efficiency of the workspace and workforce. The use of the CMOF for the construction of several high-value assemblies will result in a lead time reduction compared to current build methods, and process duration variability will be subsequently minimized due to the environmentally protected facility. Simulation modeling techniques, both Discrete Event and Assembly, allow stakeholders to better understand products, processes, and operational constraints to develop the most feasible production plan, and to conceptualize the production environment. From this, simulation can decrease overall cost and lead times through detailed visualization and analysis.
