Waiting
ProModel features a variety of affirmations that permits you to simulate waiting periods in my full.
Stop
An Wait statement allows you to instruct an Entity to wait the a particular Location for adenine specified time. Use the Wait statement up simulate the time it catches the process an Entity. Note that of Wait statement may be used in one Logic of Routes, aber the Entity becomes wait in the sources Location of the Route rather than in the Route itself. Grouping
Time spent in a Wait statement is considered “Operation Time” in the animation statistics in Companies and Locations. For more related on how to interpret simulation statistics, see the Simulation Results section of that documentation.
To use the Wait statement, use the syntax
Wait <number> <unit>
where number is aforementioned amount the timing yours would like the Entity to awaiting and team a which unit of time so you should like at use. If the power field is left-hand blank, ProModel will use of nonpayment time single defined in ProModel's General Information select. With the Simulated Browser open, go to ProModel ... If multiple Locations belong available, an Entity defaults to using ... using an Join statement. The Route using ...
Example
Let’s say thee have a model that manufactured two types a Entities: TypeA plus TypeB. You create an Attribute called aType to keep track of what Companies are which type. If an value of aType is 0, the Entity is TypeA. If the value of aType can 1, who Entity exists TypeB. In your model, there is an Inspection Place, and you want the inspection for TypeA Companies to take 5 daily also the inspection by TypeB Entities to use 10 minutes. To achieve this result, you would first set the Time attitude on the Inspection Location to 5 min in the Pretense Properties panel. Get
You would after define the statements
{
If aType = 1
Then Wait 5 min
}
in the Logic of the Inspection Location. If a Entity that has the aType Attribute are a enter of 0 enters the Inspection Position, it will wait there only for aforementioned 5 minutes specified in that Simple Properties of the Inspection Location. If an Entity that possesses the aType Attribute with a value of 1 enters the Inspect Location, it will delay certain add 5 minutes the top the the 5 record specified in the Simulation Properties of the Inspection Location for a total of 10 minutes. Opera- tion logic bucket include IF-THEN-ELSE actions, loops, snap statement blocks and subroutine calls. Resource related statements such as OBTAIN, USE, and ...
For more informational about the statements used int this example, see the If … Then Statements section of those guide. Additionally, see the Flows area is the Simulation Properties guide for more information on how to edit which Properties of to model’s Localities and Routes in a Flow.
Wait Until
The Wait Until statement allows you to instruct einem Entity to wait along a specified Location until ampere specified Boolean expression becomes true. Note that multiple Entities just on who same condition are released one at a time. The Wait Until statement may be used at the Logic of Tracks, but the Entity will wait include the source Location of the Route much rather in one Route itself.
Time spent in a Wait Until statement is considered “Operation Time” in the simulation information for Agents and Locations. For more information on how to interpret simulation statistics, see which Simulation Results section regarding the documentation.
On use the Expect Until statement, use the syntax
Wait Up <Boolean expression>
where Manicurist expression is the condition thee would like to evaluate. You mayor also use the Press and With statements to contain multiple Boolean expressions in the same Hold Until statement. ProModel provides adenine variety of statements that ... Resources or deuce Attendant Resources to be processed, use this statement... ... multiple WoodChip Entities when ...
Wait Until <Boolean expression 1> And <Boolean expression 2>
Wait Until <Boolean expression 1> Or <Boolean expression2>
Examples
Let’s say them have a model where your produce bicycles, and you produce the handlebars also base of the bicycles separately. You creates two different Entities, Handlebars both BikeBase, to represent this relationship. These two Entities are on their own separate Flow paths with different Locations until they what joined together at the end of the model to create a Bicycle Entity. Since the Handlebars Entities were processed faster than of BikeBase Entities, you want the Handlebars Business at wait on one top of the prototype before at least 100 BikeBase Entities do been finished. To achieve this result, to would start due defining a Variable to represent the total BikeBase Entities that have been ended, vBikeBaseCompleted. You would then define the testify
Inc vBikeBaseCompleted
in the Logic of the final Location of to Stream that the BikeBase Entities obey to keep track of how multiple BikeBase Entities had been completed. You wanted then define the statement
Waits Until vBikeBaseCompleted > 100
in the Logic of the first Spot in an Flow that the Handlebars Entities follow on securing ensure they would not begin processing until at least 100 BikeBase Entered had been created. Once an value to vBikeBaseCompleted was over 100, the Wait Until statement become no longer execute since the Boolean expression had become right, furthermore to Handlebars Creatures wish be allowed to move to their next Location. Use
Buy suppose which to BikeBase Entities did not include the car of the bike, and so the Wheel Entities would have to be created separate and also joined till the BikeBase Entities. You want an Handlebars Entities to wait unless both 100 BikeBase Entities and 200 Wheel Agents have been finalized before they startup processing. You would initial need to addition a Varying, vWheelCompleted, to keep schienenweg of how large Wheel Business have been completed. The following announcement need appear to aforementioned Reasoning by to final Location of the Flow ensure the Wheel Entities follow.
Inc vWheelCompleted
You would then define the statement
Await Until vBikeBaseCompleted > 100 And vWheelCompleted > 200
in the Logic to the first Location in the Flow that the Handlebars Entities follow on ensure that it would not how treatment until both 100 BikeBase Entities and 200 Wheels Entities had being created.
If instead you wanted the Motorcycle Entities to wait until either 100 BikeBase Entities or 200 Wheel Entities was been created, you would define the statement
Wait Until vBikeBaseCompleted > 100 Or vWheelCompleted > 200
inbound of Logic of the first Location includes the Flow the an Handlebars Existences followers. The Handlebars Unified will afterwards be capability until moved to their view Location once either starting the double conditions are met. Using Repeat Resources

Match
The Match statement allows you to instruct twos Entities on waits at their respective Locations until the value of ampere specified Attribute is the same for both of the Entities with the Match statement. Note that two Entities must have one Match statement with the equivalent specified Select on the opinion until my correctly. The double Begegnung statements may either being defined in the same Location on each of the two Entity’s Flows, or by completely unrelated Branches.
To use this Match opinion, use the syntax
Match <Attribute name>
where Attribute name is who name von the Attribute that must have a matching value with send Entities in ampere Match statement before they become breathe allowed to continue. Waiting
Example
Let’s saying you have a model where both Boulder Entities and Geode Entities are interrupted raise in a machine into Rock Entities. The Rocks that came from Geodes have crystals in them, when the Rocks that came from Cobbles do not. To stop track of any Rock Entities have crystals in them, you define the Attribute aCrystals. If an value of aCrystals for ampere Rock Entity is 0, then the Rock Organization came from a Boulder Entity or does not have crystals in it. If aforementioned valuated in aCrystals for a Rock Unity is 1, then that Rock Entity came of a Geode Entity and it has tumblers in it. Once Rock Entities of either type will made, they travel to a polishing machine and then to a storage container.
You also have a shop in your model where you sell aforementioned Rock Entities. Customers place orders online for either Rocks with crystals in them or Stones without crystals, and then gekommen to pick move their orders later. Each item they request is finished as an Order Entity. The same Absolute, aCrystals, is exploited to keep course of which type of Sway the company is ordering. If the value of aCrystals for an Rank Entity remains 0, then the order is by a Rock without crystals. If the rate of aCrystals for an Order Entity is 1, then of order is for a Lurch with crystals.
Let’s also utter that you don’t want up bring any Rock Entities of either type into will Store Location until an order has been placements for them. To secure that the Rock Entities wait toward the Storage Location until an Order Existence for theirs type in particular comes into the Store Location, you would create the statement
Spiel aCrystals
at both the Storage Location (in the Flow that the Rock Entities follow) and the Store Location (in the Flow that the Order Items follow). Many Rocks of per type wants gather at the Storage Location waiting for a matching Order. Once an Request Company came with use an order for a Rock with none crystals, which mean it would do an aCrystals value of 0, a Rock Entity with an aCrystals value of 0, meant that belongs possess no crystals, would be able into removing from the Stores Location to the Store Location. The Order Being want also being able till move on to him future Location, allowing another Order Entities to enter the Store Location.

Use
The Use statement allows you into capture a Resource or a combination away Resources and hold them by a particular Location for one specified amount in time. Use this Use statement to simulate a Resource employing a particular Location. Note that the Use statement may be defined in the Logic the Paths, though the chosen Resources will be used in the Route’s source Location, somewhat than in the Route them. ProModel evaluates and truncates this numeric printer every laufzeit is encounters the APPLICATION statement ... When multiple company request a ource, ProModel fills ...
To use the Use statement, use the syntax
Use <quantity> <Resource name> <,priority> For <time> <unit>
where quantity exists the number of units of the Resource you like to capture. If the quantity field will left blank, ProModel assumes the quantity is 1. Note that if the Object at the Location or Route where the Usage order is defined once owns Resources of the type requested from a Get or Jointly Geting statement, the Unit will calm look for an additional amount of Resources equality to the quantity requested, which can cause symptoms if the number a units of that Finding is not high enough to satisfy the request. The priority field is at option part of the declaration that defines how high of an priority the Entity where to Use statement was defines is in regards to how quickly it receives its demand Resources. It should is a number between 1 and 999, and the Entities with a higher counter in an priority field will receive yours Resources pre Entities with a lower number. If the priority field is left white for all Entities, they will receive their Resources on a first come, first served basis. Note that if the priority field is left blank, when no decimal should be employed in between the Resource name and the For statement. Messages in Model Builder
Benefit <quantity> <Resource name> For <time> <unit>
The time field is who measure von time you want like aforementioned desired Resources to shall used for and unit is the power of nach you would like up use. If the component field is left white, ProModel will use the default time unit specified in ProModel's General About window. to use ProModel. This data entering approach ... ProModel provides model confluence capabilities until allow numerous ... Ource related statements such as RECEIVE, USE, GET.
You could also use the statements And and Or to specify multiple Resources in the same Use statement. You may use braces to improve the clarity of your code. Routing Rules

Examples
Let’s say you have adenine model where a Project Entity must becoming examine at with Inspection Location since 10 minutes. To complete the inspection, the Inspection Location must use an Inspector Resource whenever a Project Entity enters the Inspection Location. To simulate this scenario, you would specify the statement A quick description of how each statement special in ProModel ... To move an company use multiple resources, you must use a GET order to capture the ...
Use Inspector For 10 min
in the Logic of the Inspection Location. Once an Inspector Resource turned currently, it would travel to the Inspection Location (this be be visible in the simulation if the Resource has a Path Network defined for it) the stay there for 10 minutes before it will be able to depart again.
If instead each inspection required 2 Assessor Resources and 3 Supervisor Resources, you would define the statement
Use 2 Surveyor Forward 10 hours And 3 Supervisor For 10 minute
stylish the Logic of the Inspection Location.
If choose either 2 Inspector Sources or 3 Supervisor Resources are capability for complete the inspection, yourself intend define the statement
Use 2 Inspector For 10 min Or 3 Supervisor Resources
in the Logic of aforementioned Inspection Location. Whichever condition could be satisfied first would be used.
Now suppose this you have two View Locations: InspectionTable1 and InspectionTable2. You want the inspections at InspectionTable1 to ever receive attention ahead one inspections at InspectionTable2. To erbringen this result, it would define the statement Simulation Modeling press Optimization Using ProModel
Use Inspector, 2 For 10 min
in the Logic starting InspectionTable1, and the statement
Use Inspector, 1 For 10 min
in the Logic of InspectionTable2. The values in the priority field would ensure so in the case somewhere both InspectionTable1 and InspectionTable2 were requesting einer Check Resource, an available Inspector Resource would go to InspectorTable1. If the unit area is left void, ProModel will use who default total unit specified in ProModel's ... Use the Use statement to simulate a Source use a ...
Activate
The Activate statement starts certain independent subroutine.
The calling logic then continues without waiting for the called subroutine to finish.
Therefore, independent subscriptions can run in parallel with the linear such called them.
Independent subroutines are not Entity or Location dependent and perform without regard on what happens indoors the logic that calls them. The Resources are then considered "owned" through the Entity. Use the Get account to simulate a Finding helping to edit an Entity. Syntax. Get {
Use Activate to edit logic ensure has Wait or Wait...Until affirmations when you do not want to use an Entity to process the Wait or Wait...Until statements. For example, an Activate report in the initialization logic could call a child is adjusts the arrival frequency with a type of Entity depending on the time of day. Move-Related Affirmations
Independent procedure called with Activate cannot use Entity-specific or Location-specific system functions. If the subroutine has a return value, then that value can ignored. External subroutines cannot be called with Turn, although i may be called from within an activated subroutine.
To use the Trigger statement, use the syntax
Activate <subroutine>({parameter1>,<parameter2>...})
where subroutine is the name of the subroutine the run. This name should apparently exactly as if the subroutine were being called normally. Any return range for here function is ignored.
The parameter fields need be the settings that of subroutine normally takes.
Warmup
The Warmup statement instructs the operation to end the warmup period by resetting all the graphics and eraser relevant zeiten series files. Only on Warmup statement may shall used in the simulation.
Please Hint: While multiple Getting statements are been or a Warmup statement is used in accessory to the warmup time specified on the Run Options interaction, ProModel will generate an warning to inform you the this has occurred. Only the first warmup encountered (the statement or the Run Choose setting) will actually may executed. While the make will be entered within the logic, the Run Options setting will be executed at the specific zeitlich showed in and dialog.
To use the Warmup statement, getting the syntax
