Aircraft parts that need to be repaired or changed during use (agent type - Equipment).Aircraft performing these flights and undergoing service (agent type - Plane).Regular flights from Heathrow Airport (London) to 50 airports around the world (agent type - Flight).The model is built using an agent-based approach and its operation is not specified by process diagrams, but is formed from the behavior of individual agents: During maintenance, the repair or replacement of parts may be required, in which case the aircraft is delayed and must remain in the parking lot.
If the airplane is sound, it can continue flying. In the model airplanes make flights and, on arrival at an airport, are serviced. How the model works: an agent-based approach to modeling You will find the model in the list of examples in AnyLogic Professional or University Researcher, as well as in AnyLogic Cloud. Using this model as an example, we will look at how agent-based modeling helps to analyze and plan maintenance. Eventually, the company can lose money and reputation. Servicing directly affects the flight schedules, and the level of service is reduced when there are significant delays. In this model, as in reality, aircraft wear out, they require routine checks and spare parts, as well as the emergency replacement of equipment.
Today we will look at Airlines Fleet - a model game in which you are responsible for the state of passenger aircraft that have logged thousands of hours of flight. You can also find links to other analyses at the end of the post. The aim is to improve your skills in the development and analysis of models, to teach AnyLogic's advanced capabilities, and also to show how simulation modeling is applied in different areas of business. target equals null target = warehouse //assign the object (pointed to by the variable) warehouse to target //now target and warehouse point to the same object … target = null //target forgets about the warehouse and equals null again Inheritance.In this blog post, we will take a look inside an AnyLogic air maintenance model and reveal how it works. Location target //a variable is declared without initialization. Sometimes you explicitly assign null to a variable to "forget" the object it referred to and to indicate that the object is missing or unavailable. If you declare a variable of a non-primitive type (of a class) and do not initialize it, its value will be set to null (null is a special Java literal that denotes "nothing"). The expression origin.distanceTo( destination ) is a method call – it asks the object origin to calculate the distance to another object destination. The expression new Location( 250, 470 ) is a constructor call, it creates and returns a new instance of the class Location with the given coordinates. 11:48 AM Java Basics for AnyLogic 3 of 26 Having defined such class, we can write very simple and readable code when working with the map, like this: Location origin = new Location( 0, 0 ) //create first location Location destination = new Location( 250, 470 ) //create second location double distance = origin.distanceTo( destination ) //calculate distance The locations origin and destination are objects and are instances of the class Location. Block As you can see, a class combines data and methods that work with the data. Variables (local variables and class fields) 5.
