CUVX Design – VT Team 2 Page 42(SWBS 900 - Ship Assembly and Support). The Basic Cost of Construction (BCC) is the sum of all SWBS groupcosts. Ship price includes profit. In naval ships, the Total Shipbuilder Portion is the sum of the projected cost ofchange orders and the BCC. The Total Government Portion is the sum of the cost of Government-FurnishedMaterial (GFM) and Program Managers Growth. The Total End Cost is the Sum of the Total Shipbuilder Portionand the Total Government Portion.Total Lead ShipAquisition CostTotal End CostPost-DeliveryCost (PSA)GovernmentCostShipbuilderCostOther SupportLead Ship PriceChange OrdersProgram Manager'sGrowthPayload GFEHM&E GFEOutfittingCostBasic Cost ofConstruction (BCC)MarginCostIntegration andEngineeringShip Assemblyand SupportProfitOtherSWBS CostsFigure 28. Naval Ship Acquisition Cost ComponentsBasic follow-ship costs for SWBS groups 100-600 are equal to lead ship costs, but reduced by a learning factor andinflated to the follow-ship award year. Follow-ships have significantly lower SWBS 800 and 900 costs. Followshipconstruction cost benefits from a learning curve that reduces the cost as the work force becomes more efficientat the various production processes repeated from ship to ship. The learning rate represents the percent costreduction for every doubling of the number of ships produced. Total follow-ship acquisition cost is the sum ofshipbuilder and government portions. A learning rate of 98%, total ship acquisition of 30 and production rate oftwo ships per year are assumed for calculating CUVX follow-ship acquisition costs.3.6 Optimization ResultsFigure 29 and Figure 30 show the final effectiveness-cost-risk frontiers generated by the genetic optimization.Each point in Figure 29 and Figure 30 represents objective attribute values for a feasible non-dominated shipdesign. Non-dominated frontiers for different levels of risk (OMORs) are represented by different colors. Extremedesigns (LO and HI) and distinctive “knees” in the curve (Best Buy - BB) are labeled as candidate designs fordiscussion. Alternative designs at the extremes of the frontiers (HI and LO) and at knees in the curve (BB1, 2 and3, etc.) are often the most interesting possibilities for the customer. Characteristics for these ships are shown inTable 27. The “Knees” are distinct irregularities in the curves at the top of steep slopes where substantialeffectiveness improvement occurs for a small increase in cost. The HI3 design variant shown in Figure 30 wasassigned to Team 2.Non-dominated ships include all three hullform types. The LPD modified-repeat hullform offers costadvantages and dominates the center region of the design space, but since the modified-repeat requires a specificdisplacement (25000 MT +/- 2%), low end ships with displacements less than 25000 MT and high-end ships withdisplacements greater than 25000 MT must be either general monohulls or WPTH. Low-end (cost) variants have
CUVX Design – VT Team 2 Page 43one shaft, high-end variants have two shafts. The rising slopes seen in each frontier between acquisition costs of$550M and $650M represent an increase in the number of UCAVs and UAVs with their necessary support andmanning. The higher risk frontiers represent a greater use of higher risk alternatives: WPTH, peripheral verticallaunch, separate launch deck, IPS and EMALS. HI3 has all of these alternatives, LO4 and BB2 have none. HI3 isthe largest ship with the most aircraft and crew. It has the lowest signatures, advanced double hull, and high-endcombat system. It has the lowest endurance because it is weight-constrained (29000 MT). Adding weight foraircraft and survivability provides a greater increase in effectiveness than adding fuel weight, but it costs more.BB3Figure 29.
