1、Flexsim CT,Basic Training,2,CT Model 1,PurposeBuild a very simple Flexsim CT modelDescription:-A very(very)small terminal has one berth to dock ships.-One ship comes to call every week,and the terminal owns a single crane to work the ship.-All containers are imports(discharges)and are placed in a si
2、ngle block in the yard.-The containers remain in the yard for 2 days and then leave the model as if picked up by a truck arriving at the gate.,CT Model 1 Layout,Berth PlannerGeneral Attributes,Drag BerthPlanner from Library to grid,Berth PlannerBerth Layout,Drag Berth Points to create layoutClick“Ne

4、sition=location in berth,Yard Block,Used to store containers in a yard.Often several blocks will be in the yard.A block can hold a specific set of containers,such as just“imports”or just“exports”.You can sort containers in a block,such as grouping those destined for the same ship.,10,CT Model 1 Step
5、 2,Use a truck gang to transport containers from the crane instead of the yard block.,CT Model 1 Step 2 Layout,Truck Gang,Used to move containers from one location to another.Can set the number of trucks.Can set the load/unload times and speed of trucks.,CT Modeling Paradigm,Yard,Ship,Rail,Gate,14,W
6、hat is a Simulation Model?,A purposeful and often radical abstraction of a real life system which can be used to answer questions or solve problems.It contains only those elements of reality that are needed to answer the question or solve the problem.,CT Modeling Paradigm,Yard,Ship,Gate/Rail,Yard/Ga
7、te/Rail,CT Modeling Paradigm,Ship,CT Modeling Paradigm,Yard,Gate,Ship/Rail,Yard/Ship/Rail,CT Modeling Paradigm,Gate,19,CT Model 2,PurposeBuild a gate modelDescription:-A terminals gate handles about 12000 containers per week,split up as follows:-3000-4000 laden pick ups-2000-3000 empty drop offs-100
8、0-4000 laden drop offs-1000-4000 empty pick ups-The gate is only open from 8 am to 8 pm Monday through Friday,with peak hours from 1 to 3 pm.-Entering trucks must first check in at one of 5 gates with a process time of triangular(0.2,1.0,0.4)minutes-15%of trucks must additionally go to one of 3 stat
9、ions with a process time of triangular(1.0,5.0,2.0)minutes-Once finished with check-in,trucks go into the yard and pick-up/drop-off their containers,which takes triangular(3.0,10.0,5.0)minutes,after which the trucks leave the yard-10%of drop-off trucks are dual-transaction trucks.,CT Model 2 Layout,

14、ships per week-Create two container types:empty,laden-Have cranes both discharge and load containers in the following order:1.Discharge empties2.Remove the hatch cover3.Cycle on discharging and loading ladens4.Replace the hatch cover5.Load empties-Add a second and third block to the yard.One block w
15、ill hold laden imports,another will hold laden exports,and the third will hold empties-Give the container types a dwell time of:triangular(0.5,5,1.5),CT Model 3 Layout,CT Model 3 Hatch Profile,CT Model 3 Ship Schedule,Yard Planner,On main menu click Container Terminal Yard PlannerSetup yard operatio

18、ect how containers are colored for visual representation,CT Model 3 version 2,Add another yard block designated for imports.Assign import containers to go to either import block based on a weighted search.,Yard PlannerAreas,Group blocks in Areas so containers can be assigned to a group of blocks.,Ya
19、rd PlannerSearch Strategy,Create a weighted search that matches your technique for assigning containers.,CT Model 4,PurposeLearn how to use yard equipment by extending CT Model 3.Description:-Start with CT Model 3-Add an RTG for the import and export block,and a top loader for the empty block.-Add t
20、wo truck gangs,one for each crane.-Create a travel network for the trucks to travel onOptional:-Add a berth road-Instead of using a travel network use“abstract travel times”for the trucks-Try implementing transshipment on some or all of the empty containers,CT Model 4 Layout,GantryCrane,RTG or RMGUs

23、etermines how yard resources are prioritized to work on ships,gates,or yard operations,CT Model 6,PurposeLearn more about yard dispatching,search strategies,resource assignment,and segregationDescription:-Start by opening CT Model 6 Start Point.fsm-As a class,define proper yard dispatching,resource
24、allocation and segregation rules,and implement them in the model.,CT Model 6 Layout,CT Model 7,PurposeLearn how to do a container move operation.Description:-Start with CT Model 4-Add a yard gang-After each ship leaves,use the yard gang to move all imports into a different block further into the yar

26、o pick up chassis.,CT Model 8 Layout,Wheeled Block,Used to store containers in a yard.An alternative to a Yard Block;containers are stored side-by-side on chassis instead of stacked vertically.The wheeled block uses more yard space(and chassis)than a yard block,but is faster to load/unload and does
27、not require a crane to assist.,Chassis Pool,Used to provide a(potentially limited)source of chassis for a wheeled block.,Additional CT Library Items,Used to provide a backdrop picture of your port for realistic look or layout accuracy.Used to route RTGs to different blocks when they must cover multiple blocks.From standard Flexsim library.Used to control operators travel path and direction.From standard Flexsim library.Used to control operators travel in a network to prevent congestion and collision.For modeling end-loading RMGs,and parking slotsFor model straddle carrier operations,
