Do you have sensors on your conveyors? We thought so. Don't worry, we've got you covered! In this Tips & Tricks, Gail walks us through how to model sensors to control the discrete movement of entities.

Changing Attribute Values in a Queue or Group

By Melanie Barker, Arena Simulation Consultant

You’ve probably used the Assign module to change the value of an entity’s attribute. But what if you need to change the attribute value of an entity that’s in a queue or group and you can’t remove it? That’s where the A() Variable can come in handy.

Connecting Models to Live Data

There are various methods of reading data into a model in Arena, one of the more popular methods is the Direct Read feature which allows you to read in data directly to Variables and Expressions.

Referencing Large Arrays with Sets, VAR and MEMBER

By Gail Kenny, Simulation Consultant
Published: January 23, 2017

When developing a model of a large system, you may have multiple large two-dimensional variable arrays that describe equipment parameters, facility characteristics, or other aspects of your system. Many times you can streamline your modeling effort by collecting these two-dimensional arrays under one “umbrella” and then pointing to the specific piece of information where needed in your logic.

Arena Packaging:  How Do I Model Pucks?

By Gail Kenny, Simulation Consultant
Published: January 23, 2017

Sometimes, a high speed packaging line must handle products that need to be stabilized during movement because of their size, shape, or spill potential. When this situation occurs, a common solution is to place the product into a puck, or carrier, during conveyance through the line operations. However, this can present a challenge to the modeler in exactly how to represent the introduction of empty pucks to the line, marrying the product with the puck, and de-pucking the product when complete. The following example discusses how to use pucks in a 1:1 relationship to product on a line.

Skill-Based Routing Using Arena

By Darrell Starks, Principal Engineer
Published: January 23, 2017

According to Wikipedia, skill-based routing (SBR) is a call-assignment strategy used in call centers to assign incoming calls to the most suitable agent, instead of simply choosing the next available agent. However, many types of systems have aspects where skill-based routing should be considered – retail, quick service restaurant, and even manufacturing and maintenance systems can utilize the technique. Skill-based routing occurs anytime an entity needs to be directed to a resource with the most applicable skill sets or capabilities. In this fashion, entities can be processed by resources that can provide better service or faster completion of the task.
