Chart template for total manufacturing time

Hello
I have a model that simulates a production process. I have a production plan that I introduce into a local list through a process flow. The process ends when the job list is empty and the last object/item derived from the last pull of the list exits through a decision point. I am interested in calculating the time that elapses between these two events:

Event 1: Start the counter when the FIRST instance is extracted from the list (this would be the start of manufacturing). In this case, depending on the logic, several pulls can be made at the same instant. I mention this in case it might be something to consider, as simultaneity or closely occurring events could cause issues.

Event 2: Stop the counter when the last item exits a conveyor at a specific decision point.

Is there any chart template that allows me to calculate the time that elapses between these two events? Or do I need to configure some other advanced statistics collector?

Thanks in advance for your comments.

What about work in progress? Or you can evaluate a staytime of tokens that you let enter into an activity and let them stay until your finish event occurs.

Hello Joerg

In the following video, I have tried to capture the elements involved in the described events. The job list is fed from an order table. Each row represents an order, and for each quantity of each order, I generate an entry in the job list, which is why 8 tokens are generated.

The model can start in two modes: continuous or waiting.

The continuous mode is where the list is created at the beginning, and at the same moment, those jobs can be extracted. That's why I mentioned that simultaneity could occur.

The waiting mode is the one shown in the video. In response to the action of activating the checkbox in the GUI, it starts producing.

What I am interested in measuring is the time that elapses from when the first task is extracted from that list (start of manufacturing) to when the object is deposited in the output queues (the moment I press stop in the video).

As you can see, the tokens that create the list are deleted once the list is pulled.

Have I managed to answer your question with this explanation?

Thanks in advance for your comments.

We've answered your question here. (which was another duplicate post - it seems you asked this question several times - please refrain from doing this as it can consume scarce resources)

Hello,

First of all, thank you for conducting such a thorough review of all my posts.

At no point would I want these posts, or others, to be perceived as an abuse of the limited resources available. I fully understand, appreciate, and value the help provided by your team, which is both generous and highly appreciated. Your effort and contributions are a distinctive advantage of the support offered for this software. This is particularly meaningful for novice users like myself and helps foster a sense of community.

I acknowledge my mistake and will correct it moving forward.

However, with the aim of self-reflection and improving my adherence to the forum's best practices—and without intending this to sound like a justification—I would like to clarify the origin and context of these posts.

You referenced one of my posts, but the link appears to be broken. I assume you are referring to the following three:

1. November 29th Post:

In this post, where I am currently writing, I asked if there was any TEMPLATE available to achieve what I needed. After replying to clarify the response I received, I did not receive further feedback after December 2, 2024.

Twenty days later, as the issue remained unresolved on my end, I continued working on it and concluded that no suitable template-based solution existed. For this reason, I opted to configure a Statistic Collector. Since it was a question with the same goal but a different approach, and following the forum's best practice of not combining more than two questions per post, I decided to create a new post.

2. December 20th Post: Recopilador de estadísticas del evento de List - Comunidad FlexSim

In this post, I addressed the configuration of a Statistic Collector. I received a response on January 8, to which I replied on January 10, but no further replies were received.

3. January 13th Post: How to use calculate table from statistic collector - FlexSim Community

Based on your feedback and the information gathered from other forum discussions, I managed to configure a Statistic Collector that met my needs. This led me to a new requirement: leveraging the collected data through calculations in a calculated table. Again, adhering to the principle of not combining multiple questions within the same post, I created a new question within the same context but with a different focus. This resulted in the January 13, 2025 post, which was resolved the same day.

Given this context, I would like to ask the following:

Is my approach of not nesting multiple questions within the same post justified?
Although they may seem the same, I have considered that they are not, as they have different approaches from my point of view, as I explained earlier.

Or does this approach lead to the perception that I am duplicating questions?

Posts 1 and 2 remain open because, in my view, they do not have concrete answers that fully address the problem or can be considered solutions.

Thank you in advance for your comments, which will help me improve how I communicate and manage my interactions on the forum.

Have a great weekend!

Sorry - I've corrected the link. I didn't do a 'thorough review' of you posts - it was determined that the topic of the two open posts was tracking the makespan of your orders and that was resolved (we hope!) in the answer linked. It was only while checking which of your questions was the correct one to crosslink to that answer, that it looked like the same 'makespan' question had been asked a few times. It's totally okay to discuss how solve that issue using different techniques in the same thread as that will ultimately be more useful to others searching for how to do the same thing - finding and reading multiple posts will prove more difficult for them. We're happy to help and add to the discussion - even we later discover the same issue has already been solved (by Felix in this case) in another post - we just need to raise awareness of the potential of creating duplicate work.
