Data modules
Data modules are the set of objects in the spreadsheet view of the model that define the
characteristics of various process elements, such as resources and queues.
Entity module
D ESCRIPTION
This data module defines the various entity types and their initial picture values in a
simulation. Initial costing information and holding costs are also defined for the entity.
T YPICAL USES
„
Items being produced or assembled (parts, pallets)
„
Documents (forms, e-mails, faxes, reports)
„
People moving through a process (customers, callers)
P ROMPTS
Prompt Description
Entity Type The name of the entity type being defined. This name must be unique.
Initial Picture Graphical representation of the entity at the start of the simulation. This
value can be changed during the simulation using the Assign module.
Holding Cost/Hour Hourly cost of processing the entity through the system. This cost is
incurred when the entity is anywhere in the system.
Initial VA Cost Initial cost value that will be assigned to the value-added cost attribute
of the entity. This attribute accrues the costs incurred when an entity is
spending time in a value-added activity.
Initial NVA Cost Initial cost value that will be assigned to the non-value-added cost
attribute of the entity. This attribute accrues the costs incurred when an
entity is spending time in a non-value-added activity.
Initial Waiting Cost Initial cost value that will be assigned to the waiting-cost attribute of the
entity. This attribute accrues the costs incurred when an entity is
spending time in a wait activity; e.g., waiting to be batched or waiting
for resource(s) at a Process module.
Initial Transfer Cost Initial cost value that will be assigned to the transfer cost attribute of the
entity. This attribute accrues the costs incurred when an entity is
spending time in a transfer activity.
