- A machine cycle, also known as a process loop, comprises four components. Which aspects of machine cycles are most valued? Is it necessary to be concerned about replacing individual components of machine cycles? Does the addition of another module assist in resolving the problem of switching between modules?arrow_forwardThere are six wires which need to be attached to a circuit board. A robotic device will attach the wires. The wires can be attached in any order, and the production manager wishes to determine which order would be fastest for the robot to use. Use the multiplication rule of counting to determine the number of possible sequences of assembly that must be tested. (Hint: There are six choices for the first wire, five for the second wire, four for the third wire, etc.)arrow_forwardssarrow_forward
- The production process shown below consists of five stages. The numbers in parentheses are the times in minutes to complete one unit before it moves on to the next stage. The demand rate is 46 units per hour. 2 workers workers workers Stage A (4 workers Stage B (3) a. How many workers are needed at each stage if management wants a utilization of at least 90 percent?
