- These four phases make up a machine cycle, which is also known as a process loop. What percentage of a machine's cycle time do you value the most? Should I be concerned about replacing parts of the machine cycle when they wear out? Is the problem of switching modules improved by adding a second module?arrow_forward11. You have just determined the actual number of workstations that will be used on an assembly line to be 6 using the assembly-line balancing procedure. The cycle time of the line is 5 minutes, and the sum of all that tasks required on the line is 25 minutes. Which of the following is the correct value for the resulting line's efficiency? Multiple Choice 0.990 0.500 0.973 None of these choices are correct. 0.833arrow_forwardProblem 14-1 (Algo) A manager wants to determine the number of containers to use for incoming parts for a kanban system to be installed next month. The process will have a usage rate of 87 pieces per hour. Because the process is new, the manager has assigned an inefficiency factor of 22. Each container holds 57 pieces and it takes an average of 65 minutes to complete a cycle. a-1. How many containers should be used? (Round up your answer to the next whole number.)

- A worker walks 3 steps, bends over to pick up a heavy box (then arises again), walks 8 more steps and forcefully jams the box into a tight opening between other heavy boxes. A B G A B P Aarrow_forwardThere 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.
