### Re: Using matrices to implement a search algorithm in ExtendSim

Dave, and anyone else on the forum, 1. We're still working on determining if the SPC (small patch of concrete) exists when a crater appears in the larger runway. 2. Two other analysts at work came up with some Python pseudo-code for determining if a SPC exists. 3. Which leads to questions about how ...

### Re: Using matrices to implement a search algorithm in ExtendSim

Dave, 1. Thank you for the very helpful reply. I had only given the algorithm a cursory check, and did not realize that returning the largest rectangle might not answer my information requirement. Probably I was grasping at straws. 2. After posting my original question, and following a few more slee...

### Using matrices to implement a search algorithm in ExtendSim

1. I have a search problem that can be handled with matrices and dynamic programming, but am unsure how I to implement it in ExtendSim. 2. Here's the problem: a. I'm simulating a large airfield (say, 300 feet wide and 10,000 feet long) b. Periodically, holes of varying size appear in my airfield at ...

### Named distributions in a random cell are not saved

1. I'm using ExtendSim 10.0.4 Pro with an individual license, running on a stand-alone workstation with Windows 10 Enterprise as the operating system. 2. The discrete event simulation models the time required to deliver equipment by ship. 3. One of the database tables has information about the small...

### Re: Cheat sheet for ModL in Equation(I) blocks

Robin,

1. Thanks for the cheat sheet; very helpful.

2. Also, the set of models you and Dave developed for the DESS textbook are full of excellent, elegant examples of ways to minimize model complexity while speeding execution.

### Cheat sheet for ModL in Equation(I) blocks

1. I'm not a good code writer, but am always looking at ways to improve the efficiency of my models through the use of equation-based blocks. 2. To get the 'outputs=inputs' to work correctly takes many false starts (am forever climbing the learning curve). And I've never found a thorough treatment o...

### Re: Counting Items in a Specific Range

Alex, 1. There are several ways to do this, and they don't involve a database. 2. You could use a Set Block to assign a value to an attribute that indicates what shift produced the item. Where you put the Set Block will depend on the business rules for the system (e.g., if the first shift starts wor...

### Displaying the PDF and CDF from a model

InfluenceDiagram_NTV-Fleet.JPG 1. I'd like to model an organizations annual medical expenses (AME), and then display the PDF and CDF for the result. 2. The number of accidents per month (APM) is ~Poisson(5), and the number of injuries per accident (IPA) is contained in an empirical table (e.g., p(x...
