Question 6 (Setup Everywhere) Consider the following batch-flow process consisting of three process steps performed by three machines. Process Step Step 1 Step 2 Step 3 Processing Time 0.25min./unit Setup time 30 min 0.20 min./unit 20 min 0.15 min./unit 45 min Work is processed in batches at each step. Before a batch is processed at a step, the machine at that step must be set up. (During a setup, the machine is unable to process any product.) Assume that there is a dedicated setup operator for each machine (i.e., there is always someone available to 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?

Hammond Inc. has analyzed the setup time on its computer-controlled lathe. The setup requires changing the type of fixture that holds a part. The average setup time has been 135 minutes, consisting of the following steps: Step Time (in minutes) Turn off machine and remove fixture from lathe 13 Go to tool room with fixture 15 Record replacement of fixture to tool room 18 Return to lathe 20 Clean lathe 17 Return to tool room 20 Record withdrawal of new fixture from tool room 12 Return to lathe 15 Install new fixture and turn on machine 8 Total setup time 138 Why should management be concerned about improving setup time? What do you recommend to Hammond Inc. for improving setup time? How much time would be required for a setup, using your suggestion in (b)?

An average of 1200 parts arrive to the EP chamber during an 8-hour workday. Each part goes through two stages of processing. At each stage, a single product is processed at a time, and processing takes an average of 15 seconds at the first station and 12 seconds at the second station. Inter-arrival times and service times are exponentially distributed. At the end of the second step, the product goes through a quality check. 5% of the parts fail the quality check and are sent back to the second stage of service. Parts exit the system only after they pass the quality check. Ignoring the time required to perform the quality check or in moving the part through the facility, what is the average cycle time for parts?

A cell-phone repair shop consists of three processes. Step 1 requires 4 minutes per unit, step 2 requires 6 minutes per unit and step 3 requires 2 minutes per unit. 40% of units that complete the third step require rework, which means those units must start the process over at step 2 (processing times are the same for units being reworked) and rework is always successful. Demand at the shop is 0.8 units per minute. Instruction: Round your answer to three decimal places. What is the capacity of the shop (in units per units per minute)? units per minute

A work system has five serial stations that have process times of 5, 9, 4, 9, and 8. To complete processing, a unit needs to go through all stations. What is the process cycle time of the system?

The bottleneck resource in a process has the least idle time. True or false?a. Trueb. False

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.

Please do not give solution in image format thanku The flow rate through a process is 0.5 flow units per minute. The number waiting for the process is 1. The time to do the activity in the process is 1 minute. This is a stable system. The average amount of time a flow unit spends waiting for the activity and doing the activity = ______. Enter one integer (which can be 0) and ONE decimal, so the answer looks like X.X. Any of the Xs can be a 0.

A machine makes two components; call them types A and B. It takes 630 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 4 seconds, or 15 units per minute. Suppose the machine rotates between one batch of 2,520 units of A and 2,520 units of B. In that case, what is the capacity of the machine in component pairs per minute, where a component pair is one unit of A and one unit of B? Suppose the machine rotates between one batch of 2,520 units of A and 2,520 units of B. What is the utilization of the machine? Suppose the machine rotates between one batch of 2,520 units of A and 2,520 units of B. What is the average inventory of B components? If the production schedule could be adjusted with...

Chairs are made in a process with a single resource. There are two types of chairs. The resource's processing time for the first type is 30 minutes and demand for this type is 2.3 chairs per hour. The resource's processing time for the second type is 23 minutes and demand for this type is 2.8 chairs per hour. There is 1 worker at this resource. Instruction: Round your answer to one decimal place. What is the implied utilization (%) of this resource?

In a multi-station serial process system, the capacity of the system is the equal to the capacity of the station that has the highest capacity among all stations. True False
