Consider a production line with four stations. Station 1 can produce a unit in 9minutes. Station 2 can produce a unit in 8 minutes. Station three has two identicalmachines, each of which can process a unit in 12 minutes (each unit only needs tobe processed on one of the two machines). Station 4 has two lines: one line has twocontinuous machines with a process time of 5 minutes/unit and 6 minutes/unit; theother line can produce a unit in 10 minutes. The bottleneck is station(just fill in a number in this question), the system process time ismin/unit, the cycle time ismins. If one week has5 working days and each day operates 8 hours, then the weekly capacity isunit/week.

Consider a production line with five stations in serial. The stations have the following process times in minutes (or minutes/unit). Station 1's process time is 9 minutes/unit. Station 2's process time is 10 minutes/unit. Station three has two identical machines, each of which process a unit in 12 minutes (each unit only needs to be processed on one of the two machines). Station 4's process time is 5 minutes/unit. Station 5's process time is 8 minutes/unit. Which station is the bottleneck station? a) Station 3 b) None of the other options c) Station 2 d) Station 5
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?
There is a manufacturing company that has a dedicated production line to make one specific product. The line has three stations working in serial. Inputs arrive at station 1 and the output from station 1 becomes the input to station 2. The output from station 2 is the input to station 3. The output from station 3 is the finished product. Station 1 can process 500 units per week, station 2 can process 300 units per week, and station 3 can process 400 units per week. illustrates this problem. Question Answer ↓ What is the maximum output number per week?
A local bakery is renowned for its elaborately cecorated sheet cakes. Consider the following process information: One baker is ivailable to prepare the cake batter (measuring and mixing ingredients and then adding it to baking pans). On average, this takes 10 minutes to prepare two cakes, ie. to make enough batter for 2 cakes and to add the batter to 2 cake pans. Move time to add and remove them from the oven is neglig bile, it takes 32 minutes to bake cakes - the bakery has two ovens, each able to hold 2 cakes. The one pastry chef on staff puts on an amazing show that draws a crowd all day-each cake is decorated in 6 minutes. The bakery operates 8 hours per day. Answer each of the following questions: a. What is the cycle time (in minutes per cake) of each stage - preparing, baking, and decorating? b. What is the dally process capacity? Explain. c. If orders arrive at a rate of 3 cakes every 20 minutes, can the bakery meet the caily demand Explain, Note: Be clear about how you…
A company manufactures clay bricks in batches. A batch consists of 200 bricks. The manager reports that his weekly production target is 1500 bricks. Each brick has to be processed through 5 machines on average. It takes on average 30 minutes to set up the machines and the average operation time is 6 minutes. There are 10 machines in the plant. Calculate the manufacturing lead time if the average non-operation time is 2 hrs. Calculate the production rate and If the plant operates 70 hours per week, calculate the production capacity Calculate the Production Capacity if the machines are only available for 85% of the time. Will the manager be able to meet his production target? Justify your answer.
A manufacturing company has a small production line dedicated to the production of a particular product. The line has four stations in serial. Inputs arrive at station 1 and the output from station 1 becomes the input to station 2. The output from station 2 is the input to station 3 and so on. The output from station 4 is the finished product. Station 1 can process 2,700 units per month, station 2 can process 2,500/month, station 3 can process 2,300/month, and station 4 can process 2,100/month. What station sets the maximum possible output from this system? What is that maximum output number?
A machine operates with the following production cycle: 15 minutes of setup,45 minutes of production. While in production the machine produces 2 parts per minute.What is the capacity of the machine in parts per minute?
Line A operates within 5 machines in a row. Each part has to travel from one machine to the next, in order. The first machine is a press that produces 650 parts per hour . The second machine can process 425 parts per hour. The third machine can process 550 parts per hour, and the forth machine processes 575 parts per hour. The fifth machine can process 435 parts per hour. How many parts can be produced in 8 hours, provided there are no breakdowns or changeovers?
A lab provides ultrasound service to patients. The service process consists of two steps: 1. Registration. Performed by a receptionist (Salary rate = $25/hr; Process time = 6 minutes/patient) 2. Ultrasound scan. Performed by a technician (Salary rate = $30/hr; Process time = 20 minutes/patient) Note that the ultrasound images need to be read by radiologists, but we assume that they have an ample capacity and thus will not model the role in the service process. Currently, the lab has 2 receptionists and 3 technicians. The manager anticipates demand to grow to 14 patients/hr in the near future. Thus, he plans to hire more receptionists and/or technicians to increase the service capacity to at least 14 patients/hr. What would be the extra payroll cost (in dollars per hr)?

A Printed Circuit Board (PCB) machine installs integrated circuits onto a board. Before starting to produce a board, the PCB machine requires a 16-minute setup. Once in production, the PCB machine requires only 0.19 minute per board. a. Currently, the PCB machine produces 525 boards between setups. Given this operating process, what is the capacity of the PCB machine (in boards per min)? b. Currently, the PCB machine produces 525 boards between setups. Given this operating process, what is the utilization of the PCB machine? c. Say the PCB machine produces 400 boards s between setups and demand is 2 boards per minute. Given the operating process, what is the avergae inventory of boards anf the PCB machine? d. Demand for boards occurs at the rate of 2 boards per minute. What is the smallest batch size such that the PCB machine does not constrain the flow rate through the process?
