PA 3-8 (Algo) Consider a four-step serial process.. Consider a four-step serial process with processing times given in the following list. There is one machine at each step of the process, and this is a machine-paced process. Step 1: 19 minutes per unit • Step 2: 14 minutes per unit • Step 3: 38 minutes per unit • Step 4: 17 minutes per unit Assuming that the process starts out empty, how long will it take (in hours) to complete a batch of t109 units? (Do not round intermediate calculations. Round your answer to nearest hour.) hours

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)?

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…

How many units are needed to break even if eaxh completed unit has a value of $100?

The cost of computer equipment does not include the consultant's fee to supervise installation of the equipment. True or False

None

26. Little’s Law connects three metrics of process analysis. These metrics are flow rate, flow time and inventory. True False

There 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.
