When Will You Need This?

When a Resource is only used for a fraction of the total time needed to complete processing of an Entity at an Activity, or when representing work that can’t be completed with one touch because of information or details missing. The resource is waiting on others to provide needed information.

Model Object

The following model object can be found in the model objects directory: Misc \ Long Process Time Short Resource Usage.

Ease of Use: Easy

Ease of Modification: Moderate

How to Use the Model Object

1. Open Your Model

Open your model or create a new blank model.

2. Insert the Model Object into Your Model

1. Locate the model object Long Process Time Short Resource Usage and select the insert button.

2. Move the cursor to the point of insertion and left mouse-click. The upper left corner of the model object will be inserted at the location of the mouse-click.

3. Connect to Your Model

1. Connect a percentage route from the part of your model where you would like the resource to be touched to Activity1.

4. Update Objects

1. Change the name of Activity1 to what maybe appropriate for your model.

5. Define Values

1. Define the values for scenario parameters s_TotalTime1, s_WorkTime1, s_Touches1, s_Cap_Activity1, and s_Name_of_Your_Resource1 based on the information provided under the heading Scenario Parameters below. The values for these Scenario Parameters must be provided before the simulation start.

6. Completion

The model object is now integrated into your model, you should now be able to save and then simulate the model.

Attributes, Variables, Scenario Parameters and Scenarios Usage

Variables (Local):

1. lv_TouchesDo not change. Describes how many times the entity will be touched by the resource before being completed. This can be described by a distribution.

1. s_TotalTime: User input required. Declare the total time needed to be spent by each entity, in minutes. This can be entered as a distribution.

2. s_WorkTime: User input required. Declare the work time required by each entity, in minutes. This can be entered as a distribution.

3. s_Touches: User input required. The number of times each entity is touched by the resource. This can be entered as a discrete distribution.
