A unit needs to be processed at either Machine A or Machine B for Station 2(parallel lines, both lines performing the same operations). The box is then processedat Station 3. After that, the unit needs to be processed at either Machine A, MachineB or Machine C in Station 4 before leaving the production line. The process time ofeach station/machine is indicated in the flowchart. What is the process cycle time ofthis system measured in minutes?

Sawing 20 min/unit Sanding 20 min/unit Drilling 32 min/unit Welding 30 min/unit Assembly 93 min/unit Assembly 93 min/unit Assembly 93 min/unit A production process is shown in the figure above. The drilling operation occurs separately from, and simultaneously with the sawing and sanding operations. Welding starts when both drilling and sanding operations have been completed. After welding, a product needs to go through only one of the three assembly operations (the operations are in parallel, where parallel lines perform the exact same operation). Considering the process times at stations, what is the process time of the system (in min/unit)?
A production line is a set of sequential operations established in a factory plant where components are assembled to make a finished product or where materials are put through a refining process to produce an end-product that is suitable for onward consumption. Ford have seven production lines in their manufacturing plant for their automotive parts where each production line produces 120, 100, 80, 116, 77, 94, 112 output per day. (a) As the Production Manager at Ford, you are required to submit the daily report of the production plant. Calculate the mean, median, and mode from the data based on the output that has been provided. (b) Also calculate the three critical parameters for measuring spread in the following ways: Range Variance Standard Deviation

L. Winston Martin (an allergist) has an excellent system for handling his regular patients who come in just for allergy injections. Patients arrive for an injection and fill out a name slip, which is then placed in an open slot that passes into another room staffed by one or two nurses. The specific injections for a patient are prepared, and the patient is called through a speaker system into the room to receive the injection. At certain times during the day, patient load drops and only one nurse is needed to administer the injections. Use Exhibit 712. Let's focus on the simpler case of the two-namely, when there is one nurse. Also, assume that patients arrive in a Poisson fashion and the service rate of the nurse is exponentially distributed. During this slower period, patients arrive with an interarrival time of approximately 3 minutes. It takes the nurse an average of 2.50 minutes to prepare the patients' serum and administer the injection. a. What is the average number of patients…

Due to the COVID‐19 pandemic, Julio’s Pizzeria, traditionally a high‐class, eat‐in only Italian restaurant in Malibu, has had to pivot in order to stay in business. One of their most sought‐after menu items is their sausage, ham, and pepperoni pizza. To accommodate the anticipated increase in carry‐out and delivery orders of this famous entrée, the restaurant manager, Kerry, has decided to create a small assembly line to speed up production of the pizzas. All tasks required to produce the pizza have been identified along with the time it takes to perform the task and the immediate predecessors for each task. if Desired Cycle time = Total time per hour / Demand per hour Desired Cycle time = 60 (minutes/hour) * 60 (seconds/minute) / 40 Desired Cycle time = 90 seconds and task are assigned to each work station below: Workstation 1: A, B Workstation 2: C, D, E, F, G Workstation 3: H, I then What is the efficiency of the most balanced line?

A production process at Kenneth Day Manufacturing is shown in the figure below.

A Company produces a component for use in the aerospace industry. The component consists of three parts (A, B and C), which are purchased externally and cost 50c, 60c and 70c per piece respectively. Parts A and B are assembled first on assembly line 1, which produces 150 components per hour. Part C undergoes a drilling operation before being finally assembled with the output from assembly line 1. There are six drilling machines in total, but only three are currently operational. Each drilling machine drills part C at a rate of 30 parts per hour. The final assembly line has a production capacity of 100 components per hour. At present, components are produced eight hours a day, five days a week. If the need arises, management can add a second shift of eight hours for the assembly lines only. The cost of assembly labour is 40c per assembly operation for each assembly line; the cost of drilling labour is 20c per part. For drilling, the cost of electricity is 10c per part. The overhead cost…
12-15 The wheat harvesting season in the American Midwest is short, and most farmers deliver their truckloads of wheat to a giant central storage bin within a two-week span. Because of this, wheat-filled trucks waiting to unload and return to the fields have been known to back up for a block at the receiving bin. The central bin is owned cooperatively, and it is to every farmer’s benefit to make the unloading/storage process as efficient as possible. The cost of grain deterioration caused by unloading delays, the cost of truck rental, and idle driver time are significant concerns to the cooperative members. Although farmers have difficulty quantifying crop damage, it is easy to assign a waiting and unloading cost for truck and driver of $18 per hour. The storage bin is open and operated 16 hours per day, 7 days per week, during the harvest season and is capable of unloading 35 trucks per hour according to an exponential distribution. Full trucks arrive all day long (during the hours…
