How can you share the PowerPoint?

[@amjedmajeed3187]

dear Yashar. i do my appreciation for your valuable explanation. please, i would like to know how to get EOQ amont as well safety stock? please waiting for your reply. thank you very much.

Thank you very much

You are welcome ☺️

I have used the same values as you but I am not getting the same results and am not getting output. Inventory level is 0 even after giving initial value. Machine not running its all 0. Can you help me in this?

[@muhammadblawal3492]

Hi Yashar, Do you have any model that can measure the bullwhip effect in supply chain?

[@DarrenLara12]

I have the same question. What did you do in the end, did you find sht to measure it?

[@muhammadblawal3492]

Unfortunately, i didn’t find any simulation model to calculate the bullwhip effect. I created a model by myself where on the basis of orders’ quantities of each player, i managed to calculate the bullwhip effect.

[@DarrenLara12]

@@muhammadblawal3492 That sounds really good. Did you do it in arena? Could it be any possibility to share that model? In any case, we could talk via email ([e-mail]) to explain a bit how did you calculate the bullwhip. Thanks in advance ^^

hi thank you for video but a grey screen appears as soon as i open arena. Do you have an idea about fixing this problem? (i'm using windows 10)

Hi, i want to ask you about decision module. How can i get the model to for system to decide the minimum value of variable

[@chirag_sakhare]

Hello sir, I found the video very informative. In the model you have considered service level as a constraint. Can we use service level as an second objective (maximize service level) and solve the model as a multiobjective optimization problem?? Also can we solve any multiobjective optimization problems in training and evaluation mode version of Arena software??

Hello I have to do my thesis in a production line through the arena software and I have one question.The production line is about organic solar cells , as an entity enters one roll which through processes is cut into smaller pieces.How can I do this through arena??

[@YasharAhmadov]

Hi. Arena has Duplicate and Split functions.

Hello Yashar, thank you for the video, could you please attach or send me the excel file in order to practice? thank you

[@YasharAhmadov]

Hi Driss. Sure! Please share your email address.

@@YasharAhmadov please mail me the excel file at [e-mail] thank you !!

[@YasharAhmadov]

@@ANILKUMARNAGAR Please check the video description. I have added the Excel file there. Thanks!

Hi Yashar, thank you for this very useful video. Do you mind if I ask you to share your email address with me? I have some questions about the model. Thank you again

@@YasharAhmadov Can you make a video about Monte A single buyer single vendor supply chain system faces lumpy demand that follows normal distribution with (µ,δ)= (150,30). Holding cost in the buyer and vendor is IDR 7000 /unit/month and IDR 5000/unit/month respectively. Retailing profit in buyer per unit is IDR 30000, while profit per unit in the vendor is IDR 20000. Ordering cost in the buyer when place an order to the vendor is IDR 100000/order. Based on that description, develop a spread sheet-based simulation based on periodic review order(or production) up to R policy in order to minimize the total supply chain cost (total cost of the buyer and vendor).
