Dear prof. Marquez, thaks for your videos are very useful for me. I'm a MS in Italy and I'm writing my thesis to complete my course of studies. The topic is on the evacuation of an area hit by a tropical storm. To simulate the evacuation I'm using Arena. Coud you give me some advice on using Network link and intersection with transportation?

Why are multiplying by 0.2? And in case we have 16 locations and 4 main offices, how shouw we make the calculations ?

You sound bored to teach this

Can we consider standard deviation for all the data at a time, can you please explain that.

In mine arena go (run ) doesnt work im using arena 14 in windows 7

I need to send the same batch to two different Station at the same time. I tried to use the clone module, but it makes my temporary batch turn into permanent batch. How do I do that?

nice video, MYROSLAVA WOULD APPROVE!!!

hello dear if i have two unit service how can i make the programs i mean two employee presnt the service how i do the simulation

Very good video. It will help me in my Engineering Management courses.

Hello Teacher, It's nice to meet you. Can you share an email address where I can write you?

excelente!

hello, why can't I calculate a different processing time between station in different distance of conveyor? I still got the same value even though tge distance of each station is different. Can you help me out?

How i have to configurate a single convayour with space for 4 items per time who have to wait 2 operation to be done in order to advance by one object?

You're one lazy cracker! Sound so damn lazy

Hi professor ı have question about this example, ı have similar homework and ı have to find a number of waiting customer in the queue. Can someone help me to find waiting people numbers in the queue?

This is very interesting to know thank you sir

After run the process, there's SQLite3 popup to connect database and I got report in Excel with all blank cells. How should I fix it?

How to return to the previous report style, not in Excel?

Very nice!!!!

Thank you!!

Hi, this is Elmer Gonzalez from Perú, South America working now as a professor at the Private University "Antenor Orrego" (UPAO) in Trujillo city. I remember that both, the dean of the Engineering College and you were invited as international lecturers in an International Congress here in UPAO. By the way, right now I am working in a Simulation course and your video is really excellent for my current job. I will be expecting others similar videos about this simulation software and its application in the industry. Greetings from my home country professor Alberto Marquez.

Hi. If lambda > mu, then the waiting time increases constantly. Am I right? So what should we change to show the Little's Law?

Sir, in my module using 8 trucks for three different loading sites, am using constant sequence in arrival module, how can i arrange or specify same trucks for one side i mean (1,2,3) for ist loading side and other as well throughout the shift time, or any other way to make it more convenient or close to reality.

Sir , i want to discuss one thing that i have made a model from quarry to crusher fo cement plant, now willing to add some automations regarding production increase or decrease and subsequently add or removal of trucks according to the situation. In this regard i want some suggestions from you

Good day, quite good information,... any forum, blog or discussion site that you recommend to talk and exchange information/ideas about this subject? Thanks

Hello Mr Alberto , could please help with building this arena. 1. Background Electromotors Solutions (ES), Inc. is an original equipment manufacturer (OEM) located in Scranton, PA that produces various models of electric motors used in industrial applications around the world. Due to high volatility and uncertainty of demand, the company has decided to adopt a mass customization production model. In this production strategy, the base configuration of each model class (primarily the motor housing) is produced in Scranton, but final assembly to exact customer specs is performed within their distribution warehouse located close to each major customer. The distribution/final assembly warehousing operation in Ardmore, TN that services the TN and North AL markets is the subject of this case. Electromotor Solutions - Ardmore Facility Figure 1, on the following page, shows the layout of the Electromotor Solutions - Ardmore facility. The motor housings for three different base models - Models A, B, and C - are shipped to, stored, and customized to a particular customer’s specs at this facility. Each base model has its own receiving AND shipping dock, as well as its own storage rack. However, all three models use one common assembly and packaging area before being shipped out to the customer. Assembly and packaging time varies based on the base model. Suppliers offload their load of a particular base housing model at its own receiving dock. Newly delivered base housings would wait at their receiving dock for a forktruck to take them to their designated storage bay/rack in the warehouse. Once an order arrives for a particular configuration of a base model, a fork truck is sent to the end of that model’s storage rack to carry one base housing to the assembly area. After that motor housing has been assembled into the final product, it is packaged for transport and carried via fork truck to that base model’s shipping dock. For example, Base Model A shipments would arrive at the Bay A Receiving Dock, would be carried one at a time via fork truck to the Model A Storage Bay, then removed (based on a customer order) from that storage bay and carried, one at a time, to the common assembly area once an order arrives for that motor. After assembly and packaging, that completed motor would wait for a forktruck to carry it to the Model A Shipping Dock, where it would leave the warehouse. --- Figure 1: Layout of Electromotors - Ardmore Facility Receiving Dock A Receiving Dock B Receiving Dock C Storage Bay A Storage Bay B Storage Bay C Assembly Area Packaging Shipping Dock A Shipping Dock B Shipping Dock C Model A Truckloads of 20 Model A base housings arrive at the Ardmore facility approximately every 4 hours, but transportation time varies - interarrival time is TRIA(200, 240, 480) minutes, with the first arrival at the very beginning of the workweek. Once the truck pulls up to the Model A receiving dock, the base housings wait for the single receiving dock forktruck to carry them to the beginning of the Model A storage rack, where the housing rolls down a gravity conveyor to the end of the rack and waits. Base housings are carried one at a time by the receiving dock forktruck due to their weight. These base housing are held in this storage rack until an order is received. An order for 20 of the Model A motors arrives exactly every 260 minutes, with the first order arrival 25 minutes after the start of the workweek. At that time, an automated order picker removes a base housing that is held on the Model A storage rack and informs the assembly/shipping forktruck to pick it up and carry it to Assembly. Once at Assembly, one of four assembly technicians assembles the remaining components of the motor according to the Assembly Time for the Model A motors, which is NORM(12, 3) minutes. The motor next goes to the adjoining Packaging Area, where a robot packages it for shipment to the final customer. Packaging time for the Model A motors is TRIA(2.5, 3, 3.5) minutes. After packaging, the motor waits for the assembly/shipping forktruck to carry it to the Model A Shipping Dock, where it is shipped out of the warehouse. Model B Truckloads of 20 Model B base housings arrive at the Ardmore facility approximately every 4 hours, but transportation time varies - interarrival time is TRIA(200, 240, 480) minutes, with the first arrival one day (480 minutes) after the beginning of the workweek. Once the truck pulls up to the Model B receiving dock, the base housings wait for the single receiving dock forktruck to carry them to the beginning of the Model B storage rack, where the housing rolls down a gravity conveyor to the end of the rack and waits. Base housings are carried one at a time by the receiving dock forktruck due to their weight. These base housing are held in this storage rack until an order is received. An order for 20 of the Model B motors arrives exactly every 260 minutes, with the first order arrival 505 minutes after the start of the workweek. At that time, an automated order picker removes a base housing that is held on the Model B storage rack and informs the assembly/shipping forktruck to pick it up and carry it to Assembly. Once at Assembly, one of four assembly technicians assembles the remaining components of the motor according to the Assembly Time for the Model B motors, which is TRIA(10, 12, 15) minutes. The motor next goes to the adjoining Packaging Area, where a robot packages it for shipment to the final customer. Packaging time for the Model B motors is UNIF(3, 3.5) minutes. After packaging, the motor waits for the assembly/shipping forktruck to carry it to the Model B Shipping Dock, where it is shipped out of the warehouse. Model C Truckloads of 20 Model C base housings arrive at the Ardmore facility approximately every 4 hours, but transportation time varies - interarrival time is TRIA(200, 240, 480) minutes, with the first arrival two days (960 minutes) after the start of the workweek. Once the truck pulls up to the Model C receiving dock, the base housings wait for the single receiving dock forktruck to carry them to the beginning of the Model A storage rack, where the housing rolls down a gravity conveyor to the end of the rack and waits. Base housings are carried one at a time by the receiving dock forktruck due to their weight. These base housing are held in this storage rack until an order is received. An order for 20 of the Model C motors arrives exactly every 260 minutes, with the first order arrival 985 minutes after the start of the workweek. At that time, an automated order picker removes a base housing that is held on the Model C storage rack and informs the assembly/shipping forktruck to pick it up and carry it to Assembly. Once at Assembly, one of four assembly technicians assembles the remaining components of the motor according to the Assembly Time for the Model C motors, which is UNIF(10, 14) minutes. The motor next goes to the adjoining Packaging Area, where a robot packages it for shipment to the final customer. Packaging time for the Model C motors is exactly 4 minutes. After packaging, the motor waits for the assembly/shipping forktruck to carry it to the Model C Shipping Dock, where it is shipped out of the warehouse. Material Handling Material handling within the Ardmore facility is carried out by two forktrucks - one for the incoming receiving-to-storage rack transport, and another for transport from storage rack-to-assembly and packaging, as well as from packaging-to-designated shipping dock. Therefore, the receiving forktruck handles all material handling before the storage rack, and the assembly/shipping forktruck handles all material handling after the storage rack. Each forktruck travels 2 miles per hour, or 176 feet per minute.

Hello Sir, ı created a model. but since my model is long, can I shrink it in size?

nice depiction. Thanks

Really appreciate this video, but how about the M/M/2 stimulation, how can we run that

How would you approach this if you had no original formula, and only time series data? What sort of numerical approximation techniques could you apply? I recall seeing a 5 term numerical approximation in my Quantitative Biomechanics class I studied years ago, that used 2 preceding and 2 anteceding values, though I do not recall what it is anymore and I have unfortunately lost those notes.

Hi, sir. Is it possible to download this excel file?

Very useful video. I have a question, at 13:00 you show how to change transporter velocity, is there a way to impose a transporter velocity with a Poisson distribution or with a Gaussian distribution? Thank you a lot

Excellent job

Sir, After subtracting departure from entities in system and entities in queue some of the valus in entities in system and entities in queue are negative. Is it possible?

Hello sir alberto. I want to ask about decide module. Can I use decide module, 2-way by chance? but in both process there are no true or false. Just to seperate if process 1 busy then they go to process 2.

Hi, I have a question related to Arena and decisions, I want to decide where I send a entity based on the waiting time of two processes, so I use expression if Process1.Queue < Process2.Queue, but what I get is 1 and 2, not the waiting time, could you help me to get the expression, I´m new to this.

Hi Sir , can i have a matlab code of discrete non-parametric inverse please

Good job

Good job, Can you provide a link to a video that simplify second derivative too?

Can you please share a data table so i can better understand this? 🤗🙏

Will there be a bottom-up video then? Thanks!

Hello how are you I have a model where in between two processes workers have to manually load the machines in process 2 from process 1 how best can I solve that

Por que lo hacen en ingles? les cuesta hablar español? tmr jajajaja

Thank you Sir

Hello sir I have an exercice about Arena simulation can you help me?

can we apply for M/G/1 ? I am new to this subject, Sorry for the silly question.

you're a boss

Sir, how to simulate if lamda is not constant(nonhomogeneous poisson process)?

the sequence is not correctly configured, you must put in the assign the same name that you use in the sequence data module
