A copy machine is available 24 hours a day. On a typical day, the machine produces 113 Jobs. Each Job takes about 4 minutes on the
machine, 2 minutes of which is processing time and 2 minute is setup time (logging in, defining the job). About 16 Percent of the Jobs
need to be reworked, in which case the setup time and the processing time have to be repeated. The remainder of the time, the
equipment is idle. What is the OEE of the equipment?
(Round your percentage answer to 1 decimal place.)
What is the OEE of the equipment?
0.2 percent
A copy machine is available 24 hours a day. On a typical day, the machine produces 100 jobs. Each job takes about 3 minutes on the machine, 2 minutes of which is processing time and 1 minute is setup time (logging in, defining the job). About 20 Percent of the jobs need to be reworked, in which case the setup time and the processing time have to be repeated. The remainder of the time, the equipment is idle.

- A machine makes two components; call them types A and B. It takes 250 seconds to switch production between the component types. During that time, no production occurs. When in production, each unit of A or B requires 0.5 second to be completed. The two components, A and B, are combined in an assembly process to make a final product; call it C. The assembly step can combine the two components into 1 unit every 2 seconds, or 30 units per minute. Assume there is ample demand. If the production schedule could be adjusted with the goal of minimizing inventory in the process, how many units of A should be produced before switching to component B? In other words, calculate the optimal batch size for component A. Assume the same number of units of B would be produced as well. answer:_______unitsarrow_forwardA machine makes two components; call them types A and B.

Process steps step 1 step 2 step 3 processing time 0.25min./unit 0.20 min./unit 0.15 min./unit setup time 30 min 20 min 45 min Work is processed in batches at each step. Before a batch is processed at a step, the machine atthat step must be set up. (During a setup, the machine is unable to process any product.) Assumethat there is a dedicated setup operator for each machine (i.e., there is always someone availableto perform a setup at each machine.)a.

A bottling line puts the soft drinks into plastic bottles and then packages the bottles into boxes holding 10 bottles each. The bottling line is comprised of the following four steps: (1) the bottling machine takes 1 second to fill a bottle, (2) the lid machine takes 3 seconds to cover the bottle with a lid, (3) a labeling machine takes 3 seconds per bottle, and (4) the packaging machine takes 4 seconds to place a bottle into a box. When a box has been filled with 10 bottles, a worker tending the packaging machine removes the filled box and replaces it with an empty box. Assume that the time for the worker to remove a filled box and replace it with an empty box is negligible and hence does not affect the capacity of the line.
