queue modeling blocks

resource blocks

number of items that routethrough a certain path

don't need to be connected;just present

collect data from blocks thathave a delay or processingtime (Operation, Stack, etc.)

Queue Stats block

Resource Stats block

Costs Stats block

Cost by Item block

Mean & Variance block

Activity Stats

Plotter, DE block

Histogram

must farthest to the left

required for all simulations

controls timing and passing of events

from Generic lib

uses probability distributions

connect to D input onOperations block (delay)

batch up to three items into asingle output

separate up to three item

used to separate resource from the item soitem can go forward and resource back topool

when batch/unbatch, checkPreserve Uniqueness

generates arrivals

specify arrival pattern

specify amount per arrival

alternative would be Generator block

changing arrival rate basedon exponential distribution

schedule specific arrivals atspecific times

set via

carry through entire process

Stack block

other methods?

holding area (think inbox)

can start with some items

assign attribute and priority asthey leave

can't measure wait time; useStack block instead

items leave FIFO

simulates an activity

delays item passing through

delay time constant unlessInput Random Number isattached

alternative to Operations formodeling parallel servers

also used to model multiplesimultaneous activities

allow for parallel processing

allow for parallel processing
