Simulation Parameters – SPS Production Optimizer Knowledge And Help

The Simulation Parameters menu is used to define the number of iterations to run the simulation and the length of each iteration. Setting the appropriate run quantity and run length is critical for capturing enough data to be form statistically significant model of the production system’s behavior. Simulation starts are also established in this menu. Simulation Starts define the times that new work will be pushed into the production system.

To Edit Simulation Parameters:

Open the Data Entry pane on the left side of the User Interface
Select Simulation Parameters
Select the pen button to open the Simulation Parameters menu
Select the input box for the parameter to be changed
Type in the value for that parameter
Select outside the input box of that parameter to finalize the input
Repeat as necessary
Select Close to exit the menu

To Create Simulation Starts:

Open the Data Entry pane on the left side of the User Interface
Select Simulation Parameters
Select the pen button to open the Simulation Parameters menu
Select the + Add button to add a Simulation Start
Select the drop-down input box for Item
Select the Item desired
Select the input box for Start Time in the same row as the newly added Item
Type in a value for Start Time in the format of calendar hours
Select the input box for Quantity in the same row of the newly added Item
Type in a value for Quantity (integer values only)
Select outside of the input box to finalize the input
Repeat as necessary
Select Close to exit the menu

To Edit an Existing Simulation Start:

Open the Data Entrypane on the left side of the User Interface
Select Simulation Parameters
Select the pen button to open the Simulation Parameters menu
Edit the input fields as necessary
Select Close to exit the menu

To Delete a Simulation Start:

Open the Data Entry pane on the left side of the User Interface
Select Simulation Parameters
Select the pen button to open the Simulation Parameters menu
Select the appropriate X button on the right side of the menu
Select Close to exit the menu

Resource Pool Data Element Description

Data Element	Description	Constraints
Seed	A Seed, commonly known as a Random Seed is a number used to initialize a pseudorandom number generator. A pseudorandom number generator’s sequence is completely determined by the seed. Thus, running a model with the same seed will produce the exact same results. If no seed is provided, the random values that the algorithm generates will follow a probability distribution in a pseudorandom manner.	Integer ≥ 0
Number of Runs	The number of times that the simulation will run	Integer > 0
Simulation Start (Days)	The time at which statistics will begin recording for analysis	≥ 0
Simulation End (Days)	The time at which the simulation will stop regardless of if there is remaining work to be completed. If the scope of work to be run by the system finishes before the Simulation End time, the simulation will stop prior to this set time.	> 0
Simulation Start Date	This enables the user to convert the reporting of results from simulation hours to calendar dates.	Select Date
Use Start Date	This must be checked if the user desires the results to be communicated in calendar dates. A selection of Simulation Start Date is mandatory with the selection of this check box.	Check mark
Item	Selection of a predefined item	Items
Start Time (Hours)	The time at which an item will be pushed into the production system. This time is in the format of calendar hours starting from Time = 0.	≥ 0
Quantity	The number of an item that will be pushed into the system at once at the defined start time.	> 0
