Attribute statistics

[jane]

Hi all,

If someone knows arena better than me and could help, Here is my problem:

In a serial production where items can be rejected and send back to the previous worstation. How can I keep track of the rejected items in order to get statistics on how many times a rejected item was rejected?

I am using an attribute for that but like that I have no statistics in the end

try if this thing works
Use an attribute of the rejected items using assign module. when it goes back to a station and again gets rejected move it through a decide module (after which it gets rejected) and and give the option based on entity types. the decide module will pick the rejected items of different attributes and move it through number of different entities u have or attributes of entities. put a record module on each line of the entity u want to record. each time an entity passes through its record module it will show u how many times different entities and number of entities of different types have been rejected. this is only a suggestion i havent tried it

Another approach: define an integer variable to hold the number of rejects. Each time an item is rejected, send it through an Assign block (Basic Process template) to increment that variable.
