MGMT 325 Quizzes (1-3) | Questions and Answers When new products or services are being planned, process selection occurs as a matter of course. Process selection also comes into play as a result of: (I) technological changes. (II) competitive pressures. (III) fundamental changes in demand patterns. In an environment in which demand is both substantial and stable, __________ technology tends to be the best choice. fixed automation Which of the following is not a process commonly considered in making products or delivering services? Subcontracting Layout planning is required because of: (I) efficient operations. (II) accidents or safety hazards. (III) new products or services. (IV) morale problems. As compared to rigid automation, the benefits of flexible manufacturing systems include: significantly lower fixed costs. A production line is to be designed for a job with three tasks. The task times are .3 minutes, 1.4 minutes, and .7 minutes. The minimum cycle time in minutes is: 1.4. The maximum allowable cycle time is computed as: daily operating time divided by the desired output (If this is smaller than the minimum cycle time, extra workstations will be necessary.) Which of these items would be most likely to be made with a fixed-position layout? a Boeing 777 jet aircraft (A fixed position layout brings the process to the product.) A company is designing a product layout for a new product. It plans to use this production line eight hours a day in order to meet projected demand of 480 units per day. The tasks necessary to produce this product are below. If the company wants the output rate to be equal to demand, what is the desired cycle time (in seconds)? Task Time (sec) Immediate Predecessor U 30 none V 30 U W 06 U X 12 W Y 54 X Z 30 V',Y 60 Layout design has many objectives, one of which is use workers and space efficiently. A company needs to rebalance a product layout for producing new plastic license plates. They plan to use the assembly line six hours in order to meet projected demand of 2,160 license plates each day. The following table describes the tasks involved in the production of this product. For output to equal projected demand, what will be the idle time at the second workstation of the assembly line that uses the minimum number of workstations? 1 second A company needs to rebalance a product layout for producing new plastic license plates. They plan to use the assembly line six hours in order to meet projected demand of 2,160 license plates each day. The following table describes the tasks involved in the production of this product is below. For output to equal projected demand, what will be the efficiency of the assembly line that uses the minimum number of workstations? 93.3 percent Quiz 2 Effective scheduling cannot: A. yield cost savings and improved productivity. B. reduce the need for expansion of facilities. C. improve customer service. D. eliminate the need to train employees. Which of the following is not an assumption of priority rules? A. The set of jobs is known: no new jobs arrive after processing begins. B. Setup time is independent of processing sequence. C. Finite loading is assumed. D. Processing times are deterministic. Primary considerations in scheduling high-volume systems involve: (I) coordinating the flow of inputs. (II) overcoming the disruptions to planned outputs. (III) assigning workers to work centers. The EDD priority rule usually does well with regard to: lateness. There are four resources and four jobs to be done. The time required for each resource to do each job is as follows: Resource A B C D 1 5 8 7 7 2 4 9 5 9 3 6 9 8 7 4 7 6 6 9 For the optimal schedule, what is the total number of hours required to complete these jobs? 1 to A; 2 to C; 3 to D; 4 to B Job X, which has a duration of four days, is due by the close of business on Friday, December 23. Without looking at the work already scheduled on X's required resource, the scheduler schedules X to be begun on the morning of Tuesday, December 20. This is an example of: backward scheduling. There are four resources and four jobs to be done. The time required for each resource to do each job is as follows. What is the optimal assignment of resources to jobs? 23 hours The two different approaches to load work centers in job-shop scheduling are: finite loading and infinite loading Eva, the owner of Eva's Second Time Around Wedding Dresses, currently has five dresses to be altered, shown in the order in which they arrived: If Eva uses the shortest processing time first priority rule to schedule these jobs, what will be the average number of jobs in her shop today?
