Hi Amir,
I am not from the textile industry, but I have a manufacturing background and I could tell you from my experience that usually the down time depends on the efficiency factor of the equipemnt used for production.
I think, you may have to considered following factors, before you decide on the downtime figure :
a). Equipment reliability factor based on the age and conditioning of the eqpmt.,
b). The actual production capacity as compared to the design capacity ( you are under-utilising or over utilising the eqpmt., it can have an effect on the eqpmt. performance in the long term. Supplier should be able to help you in this)
c). The life of the equipment ( depends on the age of the vehicle).
d).The Quality standards of the product versus the equipment capability.
e). Adequate Training of the technicians operating the equipment.
The downtime should include any stoppage of production due to equipment problem or quality poblem or anything else.
Hope the above info. helps you in deciding the downtime.
AVY
