    • handleEnableEvent

      protected static State.EventHandleResult handleEnableEvent(NetworkStruct sn, int ind, GlobalSync glevent, List<Matrix> glspace, List<Matrix> outglspace, Matrix inspace, Matrix spaceBuf, Matrix spaceSrv, Matrix spaceVar, Matrix fK, Matrix fKs, int mode, TransitionNodeParam transParam, int R)
      Handles ENABLE events for transitions in Stochastic Petri Net (SPN) event processing. This method processes the enabling phase of a transition firing, which checks if the transition can be enabled based on available tokens in input places and generates all possible state combinations when the transition becomes enabled. It implements the SPN semantics for transition enabling with support for multiple job classes and server allocation.
      Parameters:
      sn - Network structure containing the complete SPN model definition
      ind - Node index of the transition being processed
      glevent - Global synchronization event containing active and passive events
      glspace - Current global state space (list of states for each stateful node)
      outglspace - Output global state space to be updated
      inspace - Input state space matrix for the transition node
      spaceBuf - Buffer state space matrix (job queue states)
      spaceSrv - Server state space matrix (server allocation states)
      spaceVar - Variable state space matrix (phase variables)
      fK - Firing phases matrix for the transition
      fKs - Cumulative firing phases matrix
      mode - Current firing mode of the transition
      transParam - Transition node parameters containing enabling/firing rules
      R - Number of job classes in the network
      outspace - Output state space matrix to be populated
      outrate - Output rates matrix to be populated
      outprob - Output probabilities matrix to be populated
      Throws:
      IllegalArgumentException - if enabling conditions cannot be satisfied

      Handles FIRE events for transitions in Stochastic Petri Net (SPN) event processing. This method processes the firing phase of a transition after it has been enabled, implementing the complete SPN firing semantics including: - Calculating the enabling degree (maximum number of concurrent firings) - Processing PRE events (token consumption from input places) - Processing POST events (token production to output places) - Managing server state transitions and phase changes - Generating all possible outcome states with their associated rates and probabilities The method supports multiple job classes, multi-server environments, and complex firing patterns through multinomial probability distributions for server allocation.
      Parameters:
      sn - Network structure containing the complete SPN model definition
      ind - Node index of the transition being fired
      glevent - Global synchronization event containing active and passive events
      glspace - Current global state space (list of states for each stateful node)
      outglspace - Output global state space to be updated
      inspace - Input state space matrix for the transition node
      spaceBuf - Buffer state space matrix (job queue states)
      spaceSrv - Server state space matrix (server allocation states)
      spaceVar - Variable state space matrix (phase variables)
      fK - Firing phases matrix for the transition
      fKs - Cumulative firing phases matrix
      mode - Current firing mode of the transition
      transParam - Transition node parameters containing enabling/firing rules
      R - Number of job classes in the network
      outspace - Output state space matrix to be populated with resulting states
      outrate - Output rates matrix to be populated with transition rates
      outprob - Output probabilities matrix to be populated with firing probabilities
      Throws:
      IllegalStateException - if the transition cannot be fired from the current state
      ArithmeticException - if probability calculations result in invalid values
