3.3.1 Human Model

The human model used in Process Simulate is based on Jack (male) and Jill (female) human model. With the 3D human models you can create and simulate various number of human operations and manual work tasks in Process Simulate.

Create Human Model

The Create Human option enables you to create a new human model. When you create a new human model, you are able to select the gender, a variety of physical traits (height, weight) as well as the waist to hip ratio of the human model. The height and weight properties can either be specified as percentile size of the model or you can enter the exact numeric values for the height and weight. The percentiles available are 1%, 5%, 50%, 95% and 99%. The percentile size of the human model is derived from the database, based on which population database you choose (for example, Korean, Asian-Indian, German, etc). Alternatively, you can also select a preset model from the library.

In order to create new human model in Process Simulate, you need to have at least one human resource already defined in the Navigation Tree. This can be created either in Process Designer, as explained in chapters before, or in Process Simulate. The human resource will link your Process Simulate Study to the Human Models in your SystemRoot directory.

1. Select Human > Create Human from the menu bar.
2. The Create Human dialog box opens.
3. Choose the parameter and click OK.

Change Human Model Properties

The properties of the human model created in Process Designer can also be changed in Process Simulate. the Change Human Model Properties option enables you to change the properties of a human model.

1. Select a human model, either in the Graphic Viewer or from the Object Tree.
2. Select Human > Change Human Model Properties from the menu bar.
3. The Change Properties - Human dialog box opens, displaying similar attributes to Create Human dialog box.

This option is particularly useful if you want to analyze the ergonomic aspects of a workplace by using various human models with different characteristics. For example, if you want to examine the height of a table on which a worker has to do the assembly, you can run simulations using a tall man and a small woman. During the simulations, you can see the accessibility of all the devices on the table, showing whether a height-adjustable table is necessary or whether the workplace is already ergonomically designed.
