Model Object Library - Look Smart, Work Smart

ARRIVALS

Arrivals Weekly

Spreads arrivals over a week according to a distribution.

Arrivals Monthly

Spread arrivals over a one-month period to mimic end-of-month sales spikes.

Arrivals Quarterly

Spread arrivals over a three-month period to mimic end-of-quarter sales spikes.

Arrivals Prior to Scheduled Arrival

Allows for the planned arrival with the addition of a distribution of how early or late the entity (patient/customer/truck) arrives.

ROUTING LOGIC

Percentage Routes Change

Recursive entries by the same entity results in a different probability of failure.

Conditional Routes

Use attributes on the entity to determine the outcome of a decision. Many of these decisions can be combined to steer an entity through an entire model. A relatively simple model can have thousands of parts, each with unique routing.

Conditional Route Example

An example for the model object above.

Renege Routes

Normal renege routes work well unless a resource is being used that is not available 100% of the time. Use this object when resources are attached to the activity for which the renege takes place.

Alternating Route

Sends entities to the next activity in turn. If the next activity is busy it looks at the next in turn.

ACTIVITY PROCESSING

Decreasing Production Time

The more people in line, the shorter the processing time.

Setup Time 1

Use this model object to account for preprocessing setup for the first entity in a group of identical entities. When the entity name changes a setup is required. The object can handle any number of unique entity types and properly accounts for NVA and VA separation.

Percent of Time

This model object should be used when you have an activity where you know the total time spent at an activity in not all processing time.

BATCHING/UNBATCHING

End of Day Batching 1

Used to create “short batches” or to close a batch even though the specified batch size was not reached. You may specify any time of the day (or multiple times during the day) to “take what you have” and move to the next activity.

End of Day Batching 2

Used to create a batch of the items remaining at the end of the day, even if the batch size is larger than the specified batch size.

Batching for Multiple Entity Types

Use this object to batch multiple entity types at a single activity. Each type of entity may have its own batch size.

RESOURCES

Release Entity at the End of Shift

This model object gives greater control on the release of a resource from working on an entity. Used especially for entities with long processing times (usually multiple shifts)

Release Entity to Next Shift - 2 Shifts

Allows work to be passed from one shift to another rather than having the same resource complete the work the following day.

Release Entity to Next Shift - 3 Shifts

Same as above but with three shifts that will share work.

Changing Priorities

Allows worker priorities to change based on time of day.

ASSEMBLY

Assemble Different Subcomponents

Gives each parent entity the ability to specify how many assemblies will be attached. For example, Type 1 requires 1 hard drive while Type 2 requires 2 hard drives, etc.

KANBAN SYSTEMS

Kanban Model Object One
Kanban Model Object Two
Kanban Model Object Three - NOTE:  You will need to download all three of these before installing number one.

A building block for Kanban systems. This object has several parts in the single model.

Kanban Squares

A simple Kanban square system.

DIGITAL CLOCKS

Digital Clock

Provides a simple digital clock to show the hour and minute of the day along with an AM/PM indicator. This is used because not everyone can quickly translate, for example, 542 hours into the hour of the day during the simulation. Black face plate with white numerals.

Digital Clock and Day - Blue/White

A more detailed digital clock with the hour and minute of the day and the day of the week. Blue face with white numerals.

Digital Clock and Day - Black/Orange

Same as above with a black face and Orange numerals.

Digital Clock and Day - Gray/Black

Same as above with a gray face and black numerals.

Digital Clock and Day - White/Black

Same as above with a white face and black numerals.

LOGISTICS

Five Docks

Use this Model Object in a situation where you have five or fewer docks to receive and unload trucks. The object holds the truck until everything is unloaded, then allows the next truck to enter.

Ten Docks

Same as above, but for ten or fewer docks

Fifteen Docks

Same as above, but for fifteen or fewer docks

SPECIALTY

Airport Bus System

This Model Object consists of three parts: a terminal layer, a bus storage layer, and a bus stop layer that can be duplicated as many times as needed. With this object a detailed bus stop system could be developed in minutes.

Airport Tram

In any situation where you have a transport system with two trams or buses only two possible stops.

Hour and Daily Trigger

Use this model object when an event needs to be triggered at a specific hour of the day or day of the week timer is needed. This simple model can be used to trigger events or the collection of data at certain times during the week.

Hold for Meeting

Holds processing for required approval meetings. Meetings may take place daily, weekly, monthly, or quarterly.

Verify Distribution

Use this model object to verify the return values you would get from a distribution. This object will not be pasted into the model but rather be used to check distribution for validity.
