Concept explainers
As technology advances and new materials are synthesized, there are certain products that receive only minimal, if any, modernization attempts. Among them are the shopping carts used in grocery stores. There is a tendency to save parking spaces by not designating a return cart area. Leaving carts in the parking lots may lead to serious accidents and car damage. Furthermore, although many customers do not fill their carts that much when t shopping, they do not like to carry baskets. Other customers like to sort products as they shop. Develop an objective tree to clarify the need statement and prioritize the objectives laid out in the problem statement. You may add features that may not be listed clearly in the problem statement but will give an additional advantage to the proposed design.

- A certain job shop specializes in one-of-a-kind orders dealing with parts of medium-to-high complexity. A typical part is processed sequentially through ten machines in batch sizes of one. The shop contains a total of eight conventional machine tools and operates 40 hours per week of production time. Average time values on each part per machine are: Machining time = 0.5 hour; Work handling time = 0.3 hour; Tool change time = 0.2 hour; Setup time = 3 hours; Nonoperation time = 12 hours. A new programmable machine is being considered that can perform all ten operations in a single setup. The programming of the machine for this part will require 20 hours; however, the programming can be done off-line, without tying up the machine. Setup time will be just 2 hours because simpler fixtures will be used. Total machining time will be reduced to 80% of its previous value due to advanced tool control algorithms; work handling time will be the same as for one machine; and total tool change time…arrow_forwardA ng.cengage.com * Mind Tap - Cengage Learning Q Search this course * CENGAGE MINDTAP Homework (Ch 03) 1.

The resources that are used in the production of these two goods are not specialized-that is, dy Tools the same set of resources is equally useful in producing both smartphones and tablets. The shape of Spain's production possibilities frontier (PPF) should reflect the fact that as Spain produces more smartphones and fewer tablets, the opportunity cost of producing each additional smartphone Tips The following graphs show two possible PPFS for Spain's economy: a straight-line PPF (PPF1) and a bowed-out PPF (PPF2).

- Most of the CTDS representing Engineering products are: 3-levels. 2-levels. 4-levels. 5-levels.arrow_forwardSuppose your company has just found $100,000 worth of outdated inventory in an old warehouse (this is the original manufacturing cost). Your boss asks you to consider two options: (1) re-engineer the outdated parts at a cost of $30,000, and ideally resell them for $60,000, or (2) scrap them for $15,000 cash (which is certain) in a second-hand market. What advice would you give your boss? Explain in your own words and give the data that supports your answer.arrow_forwardOne of the most important responsibilities you have as a computer manufacturer is to provide goods that are unparalleled in terms of both their quality and their performance, all while ensuring that their costs remain reasonable. How can a machine be built that is both fast and of high quality while yet being within a reasonable price range?arrow_forward
- I am stuck on this question I have for my homework. Can you please help me out?arrow_forwardA certain job shop specializes in one-of-a-kind orders dealing with parts of medium-to-high complexity. A typical part is processed sequentially through 10 machines in batch sizes of 1. The shop contains a total of eight conventional machine tools and operates 40 hr/wk of pro duction time. Average time values on each part per machine are: machining time = 0.5 hr, work handling time = 0.3 hr, tool change time = 0.2 hr, setup time = 3 hr, and non operation time = 12 hr. A new programmable machine is being considered that can per form all 10 operations in a single setup. The programming of the machine for this part will require 20 hr; however, the programming can be done off-line, without tying up the machine. Setup time will be just 2 hr because simpler fixtures will be used. Total machining time will be reduced to 80% of its previous value due to advanced tool control algorithms; work han dling time will be the same as for one machine; and total tool change time will be reduced by…arrow_forwardManufacturing process can be divided by 5 main groups with respect to their physical action on raw materials and some of them acquire a specific machine. They can be listed as: 1. Material deposition technologies, such as casting and sintering, or the new "rapid manufacturing" techniques developed rapidly in the last ten years. 2. Joining techniques, in which riveting, friction stir welding (FSW), welding and assembly are classified. 3. Forming, where hot working techniques like forging and cold working techniques such as forming, spinning and involute splines production are placed. 4. Material separation, including shearing, nibbling, punching, cutting by laser and cutting by high pressure water or abrasive waterjet (AWJ). 5. And finally material removal processes, also known as machining processes. Using 3D metal printing is falls under which catogary? O a. No. 5 O b. No. 4 O c. No. 2 O d. no. 1 O e. No. 3arrow_forward
- B: Iraq Glass Industries Company produces two types of products, A and B, each one goes through two production stages. Product A needs 1 working hour in the first phase, and 4 working hours in the second phase, while Product B needs 2 working hours in the first phase, and 3 hours of work in the second stage. If you know that the profit per unit of product A is $60, and the profit per unit of product B is $50. The available weekly working hours in the first stage are 40 hours, and in the second stage are 120 hours.
