There are four stations in a process: Station-1, Station-2, Station-3, and Station-4. They process a single product. The flow of the accepted and rejected products are shown in the process flow chart. The total volume of production is 105 products per hour. 23% of the products of Station-1 need repair and are directed to Station-3 for repair, the rest are sent to Station-2. 15% of the products of Station-2 need repair and are directed to Station- 3 for repair, the rest are sent to Station-4. 12% of the incoming products of Station- 3 are rejected, are sold at a low price, and leave the process. The rest go to Station-4. All the products of Station-4 are good, no need to repair, and no rejection. On average there are 8, 2, 40, and 5 products in Stations 1, 2, 3, 4, respectively. Compute the average flow time in this process. Enter your answer in MINUTES with ONE DECIMAL point.
