ABC Manufacturing is evaluating the desirability of implementing process improvements and is seeking your help in determining whether it should proceed with the proposed improvements. One area of focus is how the improvements will affect processing time (manufacturing cycle time efficiency). Estimated activities and associated times for these activities under both the current process and after process improvements are as follows: Process Activity Current Process After Process Improvements Wait time 4 hours 1 hour Inspection 40 minutes 5 minutes Moving 80 minutes 20 minutes Processing (manufacturing) 2 hours 75 minutes Required: 1. Determine the manufacturing (production) lead time (in minutes) for each of the two decision alternatives. 2. Determine the manufacturing cycle efficiency (MCE) for each decision alternative.
. A small, privately owned Asian company is producing a private-label soft drink calledYoggo. A bottling line puts the soft drinks into plastic bottles and then packagesthe bottles into boxes holding 10 bottles each. The bottling line is comprised of thefollowing four steps: (1) the bottling machine takes 1 second to fill a bottle, (2) the lidmachine takes 3 seconds to cover the bottle with a lid, (3) a labeling machine takes3 seconds per bottle, and (4) the packaging machine takes 4 seconds to place a bottleinto a box. When a box has been filled with 10 bottles, a worker tending the packagingmachine removes the filled box and replaces it with an empty box. Assume that thetime for the worker to remove a filled box and replace it with an empty box is negligibleand hence does not affect the capacity of the line. Problem data are summarized in thefollowing table. a. Draw a process flow diagram of this process. b. What is the capacity (bottles/hour) at the resource “Apply a lid”? c. What…

A process of making chair is described as follows: Stage 1 Seat and back attached Stage 2 Legs attached The production speeds are 15 chairs per hour for Stage 1 and 30 chairs per hour for stage 2. The cycle time of the process is ______minutes. The flow time of the process is ______ minutes.
What is the highest possible yield a process can obtain?a. 95 percentb. 100 percentc. 200 percentd. It depends on the process
Consider the following batch-flow process consisting of three process stepsperformed by three machines. 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. What is the capacity of step 1 if the batch size is 35 parts?b. For what batch sizes is step 1 (2, 3) the bottleneck?
This is a step in a process that is the slowest compared tothe other steps. This step limits the capacity of the process.
A customer wants 38,400 parts for the next month and the production line operates continuously for 16 hours per day. It is known that the company works 20 days per month. Determine the Takt Time in parts per second.
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? Does the implementation of a second module resolve the problem of toggling between them?
Consider the following four-step assembly operation with quality problems: The first resource has a processing time of 5 minutes per unit and one employee doing the operation. The second resource has a processing time of 4 minutes per unit. It also has one employee doing the operation. However, this is a very delicate task and 80% of all products have to be scrapped after this step. Two workers are staffed for the third resource. No quality problems occur at this resource and the processing time is 20 minutes per unit. At the fourth and final resource, one operator handles the product. No quality problems exist at this step and the processing time is 12 minutes per unit. For every unit of demand, how many units have to flow through the second step in the process?
