Today is my three year anniversary of blogging. I picked up this hobby after early retirement and started off writing about weird little problems. Now weird problems are turning up in my dreams. Some of these quarantine stress dreams have taken me back to old career dilemmas. As a supply chain manager with demanding production requirements, I was warned never to run out of anything! One of the commodities we tinkered with repeatedly was toilet paper. Limits on storage space and variable work forces kept the Economic Order Quantity in constant check. Living and dreaming through this pandemic have taught me that none of the versions of that EOQ formula are relevant. I now know the answer depends on how many cats you have, what brand you are talking about and whether there are suitable substitutions.
