Simulation Tip: Data Driven vs Hard Coding

Posted by Melanie Barker on Jul 8, 2019 3:58:21 PM

While simulation tools have improved over time, most of these improvements have been in regards to simplifying technical hurdles, like importing data or making the user interface easier to understand. The complexity of how to break down a complicated, real-world process into concrete steps that can be modeled in a simulation language continues to be the most difficult part of using any package.

Arena Packaging:  How Do I Model Pucks?

Posted by Gail Kenny on May 2, 2019 1:01:48 PM

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.

Arena: The Original Twin

Posted by Sample HubSpot User on Dec 4, 2018 10:13:00 AM

The value of simulation is pretty well documented, however our clients who have been able to achieve the greatest value from simulation are those who recognized that it was important to apply simulation when a new project is just beginning to be formulated.  Simulation is the original digital twin of a system and it allows you to play with a system in the virtual world and gain insight into what a proposed change may mean to production, scheduling or even determine if perhaps the current system is adequate.   Generally speaking, any investment in simulation is typically money well spent, so long as it is a good simulation and not just pretty animation, because it helps determine the best use of capital. Even if the decision is made not to change something, it prevented someone from taking a risk and making a change for the sake of change that likely would have been less effective or even more costly.

NEW: Direct Read Sets

Posted by Darrell Starks on Jan 12, 2018 9:27:00 PM

The Direct Read feature has been Arena for a few years now but the capability has been expanded to more Arena elements, making it easier to import data directly into Arena for ease of use in analyzing data.   For those of you who haven’t used the Direct Read functionality within Arena, it is definitely a feature worth taking a look at.  Direct Read allows you to link elements in Arena with data sources so that Arena will read in the values for those elements from the data source.  This means that you can create an Excel file and have data defined for your model in a workbook that you will link via Named Ranges to Recordsets in Arena.

Why We Do What We Do

Posted by Rob Kranz on Jan 12, 2018 9:20:00 PM

Companies spend lots of time and effort defining vision and mission for their organizations.  These are important to ensure that teams are aligned with its direction and that everyone clearly understands where they are going as a company.  While vision and strategy are important, companies often ignore the most critical question:  “Why?”  Why do we do what we do?

Using Pickup to Model Tracking

Posted by Melanie Barker on Oct 3, 2017 9:36:00 PM

Complex, expensive vehicles – such as airplanes or trucks – often contain a number of parts that will fail over the lifetime of the item. Approaching the modeling of this usage and failure tracking can be a tricky prospect. One solution is to use the entity’s attributes to model each part. Attributes can even be arrayed to contain additional information about the individual part, such as the installation date, number of trips made or miles logged, part number, and a unique identification code. But since every entity has a copy of every attribute, what happens when different vehicles have different part requirements? The number of attributes needed to manage this level of complexity can quickly become overwhelming and cumbersome.

It’s Not All About the Average

Posted by Melanie Barker on Oct 3, 2017 9:34:00 PM

Worldwide, the average human is 5’6” (167cm) tall. This is a true fact – I know because I found it on the internet. However, is it a useful fact? Assume for a moment that you are a manufacturer of blue jeans. Would you take this average height value and then size all of your equipment so that it can only make jeans for individuals who are exactly this height? Now imagine your business was more narrowly focused in terms of your potential customer pool, e.g. men living in the United States. If you’re aiming for a smaller group, would it make any more sense to buy equipment that only makes one length of jeans? Or should you take the range of potential heights into account when designing your factory?

Launch Probability in NASA Space Launch System

Posted by Grant Cates, Ph.D. on Oct 3, 2017 9:33:00 PM

Launcher’s Lurgy causes space launch vehicles to be delayed relative to their planned launch date. The disorder is similar in nature to Loser’s Lurgy, a condition causing Quidditch players to perform poorly, first described by Luna Lovegood in J.K. Rowling’s enormously successful Harry Potter series. Pretty much all rockets have Launcher’s Lurgy with launch delays being all too annoyingly common. For example, a quick search on the word “delayed” on Spaceflight Now’s launch history log web page[1] results in more than 100 matches (the search engine’s limit). There is no known cure for Launcher’s Lurgy but simulation modeling can be used to develop predictions for how many launches can be achieved over a particular time period and when any particular launch of interest is likely to launch by.
