  1. I found the answer again. For those who want to know: step 1) Add replenishment policy property to data table step 2) Chose a default value for replenishment policy step 3) Click default values of dynamic properties According to selection made in step2, the list of properties now appear at step 3. (If min/max is selected OrderUptoLevel and Reorder Point will appear)
  2. I want to create a list of materials from data table. I can refer to inventory replenishment policy from table by adding by adding "replenishment policy" property from data tables. But how do I define the default values of Re order point and Up to Level parameters for these auto-created materials? I cannot see such option even in the built in Material Table Scheme. Any help is really appreciated. Kind regards
  3. Yes it is possible. There are very good simbits about this also with loopback rules and predecessor method. Write task sequence in simbits you will see it. Hope it helps.
  4. Zan, I think we were facing the same problem. I found the solution. You can check here. Hope it helps.
  5. I found the answer For those who wants to know when you add "BOMActionRules" enumeration property to data table, you can refer it from the task details in server object.
  6. Hi all, I want to create a list of tasks from data table which I will use in the server objects tasks sequence. When I want to refer to all of the properties of material requirements to data tables, I am facing a restriction as follows: a) I can refer the material "Action Type" (Consume\Produce) property from server object to data table by adding an "MaterialActionType" enumeration property to data table. b) If referencing in a) was NOT done, for the selected action type (lets say produce was selected), I can refer the "production type" (Material/Bill of Materials) property by adding a "MaterialOptions" enumeration property to data table. However, when I do the task in a) an additional row appears in server object, now showing both consumption type and production type in properties. Then I am unable to set reference to data table as in b) any more. Is it possible to refer BOTH "Action Type" (Consume/Produce) and "Material Options" (Material/BOM) simulatenously? If yes how? Could you please guide? Kind regards, Tolgahan
  7. How can we add a secondary resource requirement to the Crane such as Operator?
  8. Hi again Liz. I found the problem but it wasn't easy to figure out with the RowForKey formula. I used the search function with tablerows as collection type. When I filtered the trace on the search and tally process, I found that the the table index of the found item and index of the search function was not the same in some cases especially for "small" type products. Further even the available row count of the products table was not returning the correct number rows in the table. The products table has 810 rows but it was finding 197 rows only in the search function. I had a separate "productsize" table which consists of "size" key string property and some other real type properties such as forklift capacity for each product size. I had used this productsize.size as foreign key in my main products table. I figured that the search function automatically filters to the products those matches the size of the product eventhough in search function match condition I only write ModelEntity.EntityType==Products.ProductName. When I removed the foreign key from the products table the problem was solved. Thanks for your help anyway. It was very useful and saved a ton of time from me.
  9. Thanks you so much for you help Liz. That's such an advanced modeling techinique I had never heard of before. I would never be able to figure it out myself. It has almost worked but correctly. It has recorded the results for some tallies correctly but recorded some tallies on the wrong tally. I think there is a problem with the set row feature somewhere. I have no problem with setting rows elsewhere in the model such as arrivals from production and arrivals from truck tables create entities correctly with all their state variables. The product list table also has unique "productnames" (entity instances), set as key and auto set-row property is set to true. I have added another coloumn with element tally statistics reference (DistanceOnForklift) to products table. I have auto created it as you suggested and turned on the auto-set row feature to true. Both my product names and tally statistics coloumn are set as key in same "products" table. But the tally step still doesnt record them to the correct tally statistics. Where am I doing wrong? Would you still be able to help me? Shall I send you the model in private message? Here is the formula I have inputted 'Products[Products.ProductName.RowForKey(ModelEntity.EntityType.Name)].DistanceOnForklift' and in the picture below you can see that tally step records into wrong tally element on last three entries. I would be glad if you could help me.
  10. Thank you so much Liz! I understand exactly what you mean. However we thought that using Tallies would give more correct results for the average value calculations. I am also thining that running and add on process on "run ending" would allow me to calculate the distances statistics for all the entities even if they are not destroyed. Now I know how to calculate it but there are around 800 different product types. So I have to write 800 if conditions saying if decide, entity.type.name == "A" is true, Tally "distanceonforkliftA", on false exit, if decide entity.type.name == "B", Tally "distanceonforkliftB" etc. Is there a way to automatically create tally statistics for each entity instance?
  11. Hi Everyone, I have 100s of different products in a warehouse and I want to get statistics for all of them such as distance travelled, number entered and exited. So I created the entity instances for each product automatically through data table. The entity.totaldistancetraveled function doesnt increase since the entity doesnt moveby itself but moved by forklift instead. So I have created a state variable called "distanceonforklift" and increased by the difference between the forklift total distance travelled value when entity exits and enters to forklift. I have also created a function called "distancefunction" on the entity and equated it to "distanceonforklift" state variable of the entity. For the return type of function I have chosen "number" and set the unit to "length". I validated that both distance state variable and function is calculated correctly in the facility window. However I cannot output the result of this state variable on the model results screen. I used the following expression under model outputstatistic but it didnt work. "ProductA.DistanceFunction". That expression gives me 0 value although there are some entities of this product which enters and exits the system. How can I see the average total distance travelled on forklift for the whole population of Product A?
