摘要：To meet the demand of modern lean ship building mode and to draw up the
   ship block-building planning in practical production of shipyard,a
   simulation and optimization method based on virtual manufacturing
   technology was proposed.With this method,the simulation model was
   established according to current process and method of planning in
   domestic shipbuilding enterprises.In the simulation system and
   optimization model,the start date of each working procedure of ship
   blocks and locating of assembling fields were considered as optimization
   parameters,shipyards resources,production capacity and site conditions
   as constraints,and delay rates of total project,delay rated of project
   segments,utilization rate of assembly fields and average workload
   saturation as evaluation indexes to establish the evaluation model and
   optimization objective.Besides,the simulation and optimization of ship
   block-building planning was realized.To increase feasible domain of
   parameters and flexibility of scheduling,the virtual node "store date
   for planning adjusting" was added before the important procedure as
   optimization parameters so as to gurantee the feasibility of the ship
   block-building scheduling.
