Recently on site we have started collecting efficiency data on the distillation columns, but they are pushing to start collecting data on the batches as well. Unfortunately, the person on site who knew the most about PI left and I don't know where to start and how to go about this. We have PI batch, but we don't use PI asset framework much. I was wondering what program would be the easiest to keep track of batches, while being able to collect data on where we are losing time when it isn't running like our golden batch. Any sort of starting point would be much appreciated.
