ISOM 351 Exam 2 Flashcards - Quizlet
A lumber mill is capable of producing 10,000 board feet of lumber per day, when it runs ten hours per day with minimal breaks. Over the past year, forestry legislation has reduced the availability of raw materials, so the mill has produced an average of 4,575 board feet per day. What is the capacity of the plant? a. 4,575 board feet/dayRead more
