CYCLONE

• A symbolic graphic format for simulation of
  construction processes
• Three basic modeling shapes
• Active state (square node represents a work task)
  
• Idle State (circle represents a delay or waiting
  position for a resource entity)
• Directional Flow (arc represents the path of a
  resource entity as it moves between idle and
  active states)

CYCLONE Active State Modeling Element (1)

• NORMAL Work task unconstrained in its
  starting logic and indicates active processing of
  (or by) resource entities

CYCLONE Active State Modeling Element (2)

• COMBI Constrained work task which is
  logically constrained in its starting logic,
  otherwise similar to NORMAL

CYCLONE Idle State Modeling Element

• Q NODE The idle state of a resource entity
  symbolically represent a queuing up or waiting
  for use passive state of resources

• Original CYCLONE Modeling Element
• Simphony Connection between the elements

Supplementary Modeling Elements in CYCLONE

• GENERATE Units can be generated (as required
  during the process) at QUEUE nodes
• CONSOLIDATE Aggregate units
• COUNTER Count the number of entities passing
• BRANCH Probability branching (Only in Simphony
  version)

Properties and Rules of CYCLONE Modeling Elements
16
CYCLONE NORMAL
Resource Entity Arrival
Resource Entity Departure

• No QUEUE before NORMAL
• Several entities can traverse it simultaneously
• If more than one resource type is connected,
  work task can be processed by either resource.

All three resourcesare required
Resource entities departure

• All resources are required to process the work

CYCLONE QUEUE
Resource entities released sequentially to a
following COMBI node when the COMBI ingredience
logic is satisfied

• QUEUE nodes always precede COMBI nodes
