Suppose a resource has setup times and a setup time must be incurred each time theresource switches production to a different product. Requiring the resource to make anew product (that requires its own setup) is likely to have what effect on the process?a. Inventory for existing products remains the same, but the process must now carryinventory of the new product.b. Inventory of all products is likely to increase.c. Inventory of existing products decreases even though the process must now carryinventory of the new product.d. Inventory of products with short setup times will decrease, while inventory of products with long setup times will increase.
What is the difference between a push system and a pull system?(a) A push system favors running a machine, even if there exists no demand for it.(b) In a pull system, the last resource is paced directly by demand.(c) Generally, there will be less inventory in a pull system.(d) All of the above
H4.
A manufacturing process consists of three processes. Step 1 requires 4 minutes per unit, step 2 requires 6 minutes per unit, and step 3 requires 7 minutes per unit. 20% 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 0.4 units per minute.
What is the capacity of the shop (in units per minute)?

- Which of the following statements is true? In a factory operating at capacity, every machine and person should be working at the maximum possible rate. One way to increase the effective utilization of a bottleneck is to reduce the number of defective units.arrow_forwardTo find the bottleneck in a process with attrition loss, all we need to do is find theresource with the lowest capacity. True or false?a. Trueb. Falsearrow_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. What is the OEE of the equipment? answer:______percentarrow_forward
- An automated machine runs for an 8-hr shift and requires an operator to run it. There are a few planned breakouts such as a 45-minute lunch break and a 10-minute production update break in the morning and a15-minute break during the shift. There are unplanned breakdown reports that have shown a repeatable average of 50 minutes per shift. The machine requires 25 minutes of tooling changeover and 25 minutes for adjustments to get a good product yield. Idling & minor stoppages account for an average of 10 minutes per shift. The machine only produces 3% defective product which includes any start-up adjustment losses. Calculate the Overall Equipment Effectiveness (OEE) for the equipment given the data.arrow_forwardn a manufacturing process, a molded part spends 7 hours in inventory before being placed in a deburring machine, where the part is processed for 2 minutes. After deburring, the part spends 4 hours in inventory waiting for its turn on the polishing machine. The part then spends 7 minutes in polishing before waiting 6 hours in line to be painted. The part goes through a painting process that takes 7 minutes, then spends 11 hours in inventory before being shipped to the customer. What is the percentage of value-added time for the part?arrow_forwardAn intermittent processing can take the form of batch processing or a a job shop. O a. TRUE Ob FALSEarrow_forward
- 22. A system has two processes and three identical resources. Each process needs a maximum of two resources. Is deadlock possible? Explain your answer.arrow_forward67. The number of resources requested by a process : a. must always be less than the total number of resources available in the system b. must always be equal to the total number of resources available in the system c. must not exceed the total number of resources available in the system d. must exceed the total number of resources available in the systemarrow_forwardIf the takt time is shorter than the cycle time, the process needs to run faster. True orfalse?a. Trueb. Falsearrow_forward
- A Printed Circuit Board (PCB) machine installs integrated circuits onto a board. Before starting to produce a board, the PCB machine requires a 20-minute setup. Once in production, the PCB machine requires only 0.15 minute per board. Assume there is ample demand. Currently, the PCB machine produces 500 boards between setups. Given this operating process, what is the capacity of the PCB machine (in boards per minutes)? answer:_________boards per minutearrow_forwardNote- need a correct option without explanation as fast as possible!! The three-stage operations model requires transformation of the input resource into some form of output. Any one 'resource' can be involved at all three stages. True or false? A)True B)Falsearrow_forward25. Two parallel activities in a process can have different capacities. True Falsearrow_forward
