Difference between object properties and object states.

Object properties :

Properties are defined within an object by the user that controls the behavior of the object. Properties can be of many different types such as network, entity, expression…

Object properties can not change definition during a run.

The value of a property is unique to each objects instance.

Object states :

States are defined within an object to hold the value of something that might change while a model is running

States can be discrete and continuous

A state on an entity is often thought of as an attribute of that entity

A state on a model can in some ways be thought of a global variable

Consider a process associated with a server object. What is the difference between a token’s parent object and its associated object?

  1. A token is an object delegate that goes through the steps of a process.

  2. The parent object is an instance of the object in which the process is defined.

  3. The associated object is the related object that triggered this process to execute.

The difference between, is an associated object is not part of the actual process a token passes through.

Develop a queuing model that gives the steady-state values analogous to teh values in Table 5.2

Create a DMV from table 5.8; How many replications should be run in order to be confident about your results?

The larger the variance in your model, the more replications you should run to be confident in your results. If you run the program long enough, say over 30 hours; the sample means of replication should approach something you can be confident in.

Animate your model
