Question
Chapter 7, Problem 1CQ
Summary Introduction
To determine: The setup time of the process.
Expert Solution & Answer
Explanation of Solution
Correct option: (c)
Correct answer:
100 minutes.
Justification:
The amount of agent added to the vat determines the setup time of the process. The reaction time of 85 minutes does not depend on the volume present in the batch and so it will be the setup time. In addition to that, 15 minutes is required to perform the cleaning process and it is also not dependent on the amount added to the vat. Therefore, the total setup time would be:
The total setup time is 100 minutes.

The Flip Chip Company manufactures nacho chips, potato chips, and related products. There has been a problem in the manufacture of nacho chips. The process begins with the mixing of water, corn and lime (called the MASA). A mixer can produce a batch of 300 lbs of MASA in 2 minutes. The MASA is then cooked. This takes 30 minutes. Only 95% of the MASA makes it to the ovens and of that only 75% is transferred to the next step. There are four ovens. The next step is chip making. The MASA is extruded into the chip itself and the chips are baked. There are 2 chip machines. A total of 950 chips/minute are produced (each chip weighs approximately .5oz). The yield from this process is 72%. The chips are then placed in 20 oz bags. This step takes 2 seconds for each bag.
Where is the bottleneck?
What recommendation would you make?
Printed Circuit Boards
You are a supplier of printed circuit boards (PCBs). Production of the circuit boards consists of several steps – Surface Mounting, Baking, and Final Assembly. Surface Mounting puts integrated circuits (ICs) and other components on a PCB. These PCBs are then Baked as a batch and kept in an oven for some time so that the ICs are soldered onto the PCBs. Finally, these PCBs are taken and manually assembled into a case, and wired with connectors. The processing rate at the Surface Mounting station is 15 PCBs/minute, the processing rate for Baking is 5 PCBs/minute, and the processing rate for Final Assembly is 3 PCBs/minute. If there are on average 24 units of (work in process) inventory and the system is working at capacity, what is the flow (throughput) time for PCBs?
Mrs. Freddy Mitchell, in her lecture, stated that a transaction processing system (TPS) is software that ensures the completion of business transactions and keeps track of those business transactions. An online transaction processing system (OTPS) is an equivalent system that online merchants use for e-commerce. The TPS ensures that each transaction is successful by storing, sending, and receiving information via a database. She added that because the process is lengthy, it is broken down into cycles, which are broken further into systems and subsystems.
Zara- Lee, a participant in Mrs. Freddy Mitchell’s Lecture series, got confused as Mrs. Freddy Mitchell began to elaborate on the many different systems, and Zara- Lee mentioned to YOU that she is experiencing information overload.
YOU then responded that Mrs. Freddy Mitchell’s explanation was clear and concise, and YOU would explain the revenue cycle, its components, and the sub-systems that constitute that cycle after class.…

- This is a step in a process that is the slowest compared tothe other steps. This step limits the capacity of the process.arrow_forwardA copy machine is available 24 hours a day. On a typical day, the machine produces 100 jobs. Each job takes about 3 minutes on the machine, 2 minutes of which is processing time and 1 minute is setup time (logging in, defining the job). About 20 Percent of the jobs need to be reworked, in which case the setup time and the processing time have to be repeated. The remainder of the time, the equipment is idle.

- JCL Inc. is a major chip manufacturing firm that sells its products to computer manufacturers like Dell, Gateway, and others. In simplified terms, chip making at JCL Inc. involves three basic operations: depositing, patterning, and etching. Depositing: Using chemical vapor deposition (CVD) technology, an insulating material is deposited on the wafer surface, forming a thin layer of solid material on the chip. Patterning: Photolithography projects a microscopic circuit pattern on the wafer surface, which has a light-sensitive chemical like the emulsion on photographic film. It is repeated many times as each layer of the chip is built. Etching: Etching removes selected material from the chip surface to create the device structures. The table below lists the required processing times and setup times at each of the steps. There is unlimited space for buffer inventory between these steps. Assume that the unit of production is a wafer, from which individual chips are cut at a later…arrow_forwardThe information turnaround time is driven primarily by:a. the number of workers.b. the IT system.c. the inventory in the process.d. the amount of waste in the process.arrow_forwardJCL Inc. is a major chip manufacturing firm that sells its products to computer manufacturers like Dell, HP, and others.

On the average, a newproduct begins at stage 1 every 6 minutes. The average timeit takes to process the product at each stage is as follows:stage 1, 3 minutes; stage 2, 2 minutes; stage 3, 1 minute.After finishing at stage 3, the product is inspected (assumethis takes no time). Ten percent of the final products arefound to have a defective part and must return to stage 1 andgo through the entire system again. After completing stage3, 20% of the final products are found to be defective. Theymust return to stage 2 and pass through 2 and 3 again. Onthe average, how many jobs are in the system?

The manufacturing process includes stamping, final assembly, testing and shipping. In the stamping operation, a number of individuals are responsible for stamping the steel outer surface of the appliance. The stamping operation is set up prior to each run. A run of 75 stamping is completed after each setup. A setup requires 40 minutes the parts wait for the setup to be completed before stamping begins. Each stamping requires 5 minutes of operating time. After each batch is completed, the operator moves stamp the stamped covers to the final assembly area. This move takes 10 minutes to complete. The final assembly for each appliance unit requires 18 minutes and is also done in batches of 75 appliance units. The batch of 75 appliance units is moved into the test building, which is crossed street. The move takes 25 minutes. In the final test, the 75 unit batch is tested one at a time.
