The CTMAX function returns the maximum cycle-time associated with time-stamped batches of material moving through a flow. CTMAX will operate in one of two distinct modes, depending upon whether the optional instantaneous argument is set to 1. When instantaneous is not specified (or set to zero), CTMAX will return the maximum cycle time associated with time-stamped batches of material which have moved through a flow, over the course of a simulation. When instantaneous is set to 1, CTMAX will return the maximum cycle-time associated with time-stamped material which is currently moving through the flow.
The optional initial parameter is applicable only when instantaneous is not specified (or set to zero). In this case, the initial value will be the value that is returned by the function until the time-stamped portion of the flow volume becomes positive. If initial is not specified, CTMAX will return a zero until the time-stamped portion of the flow volume is positive.
CTMAX becomes particularly relevant when more than one time-stamped flow enters a conserved flow chain, or when different batches get mixed together somewhere in a process (for example, in a Conveyor with variable transit time). In either case, material with different time-stamps can exit the process simultaneously. CTMAX will provide you with the maximum cycle-time associated with stuff which is moving through the flow.
When you are operating in the Normal simulation mode (in the Time Specs dialog, under the Run menu), or when time stamping has been turned off for all upstream flows in a conserved flow chain, CTMAX will return a zero. Any initial values of material in a conserved stock/flow chain will not be time-stamped, and hence will not be used for cycle-time purposes. When operating in its instantaneous mode, CTMAX will return a zero when the time-stamped portion of the flow volume is zero.
