12. The diagram below represents a process where two components are made at stations A1 and A2 (one component is made at Al and the other at A2). These components are then assembled at station B and moved through the rest of the process, where some additional work is completed at stations C, D, and E. Assume that one and only one person is allowed at each station. Assume that the tim E= 0.55 min below for each station represent the amount of work that needs to be done at that st = 60/0.55 that person, with no processing time variation. Assume that inventory is not allowed = 109 units in the system. What is the average hourly output of the process when it is in normal operation? Notes: 1 person per machine and no inventory in the system A = 0.3+0.4 B=0.75 min C= 0.65 min D= 0.60 min D= 0.60 min 0.7min = 60/0.75 = 60/0.65 = 60/0.60 = 60/0.60 60/0.7 85.7 units = 80 units = 92 units = 100units = 100units Dari proses diatas, dapat diketahui bahwa produksi terkecil adalah sebanyak 80 unit. Oleh karena itu, kita dapat menyimpulkan bahwa setiap mesin dapat memproses seba unit. Jadi, rata-rata output per jam adalah 80 unit. E= 0.55 min = 60/0.55 13. A certain custom engraving shop has traditionally had orders for between 1 and = 109 units
