- The University of Central Lancashire has decided to adopt a new human access control system for both employees and students using biometricfingerprint recognition. For students, the system automatically links to the central attendance management system and logs a student’s attendance,and lateness based on when they scan their fingerprint before entering the classroom. For faculty, it automatically records a staff member’s workstatus and commitment, including work status, overtime hours and holiday record. The system should interact with other local and enterprise levelapplications including scheduling and facilities management to develop the staff and student weekly schedule and also grant both faculty and studentsaccess to the specific rooms and facilities based on their schedule through fingerprint recognition software. Analysis using business support matrix. (create the table please)Process Capability (Cpk and Cp) The operations manager of an insurance claimsprocessing department wants to determine the claims-processing capability. Claims usually take a minimum of four days to handle. The company has a commitment to handle all claims within 10 days. On average, claims are processed in eight days and processing has a standard deviation of one day.a. Compute Cp and Cpk for the claims-processing department. Based on these computations, should the claims department improve its process?b. Using the same data, recompute Cpk, but use an average claims-processing time of seven days instead of eight days.c. Using the original data, recompute Cpk, but use a standard deviation of 2/3 of a day. Which change made the most improvement—the change in mean in part b or the change in standard deviation? Can you explain the results?What is an Interactive Single Variable process control loop? in details
- The mean service time (x¯) of a hairdresser is 18 minutes with a standard deviation (σ) of 2 minutes. Upper specification limit (USL) is 22 minutes, whereas lower specification limit (LSL) is 15 minutes for this process. What is the process capability index (cpk) for this process? Is the process capable? Cpk=0.67, capable Cpk=1.5, capable Cpk=0.67, not capable Cpk=0.5, capable Cpk=0.5, not capableA machine is set to pump cleanser into a process at the rate of 5 gallons per minute. Upon inspection, it is learned that the machine actually pumps cleanser at a rate described by the uniform distribution over the interval 5.0 to 8.0 gallons per minute. Would you expect the machine to pump more than 7.85 gallons per minute?The average time to process a request at a web server is 10 milliseconds. Thestandard deviation of the processing times is 15 milliseconds. What is the coefficient of variation of the processing times?
- Output from a process contains 0.02 defective unit. Defective units that go undetected into final assemblies cost $25 each to replace. An inspection process, which would detect and remove all defectives, can be established to test these units. However, the inspector, who can test 20 units per hour, is paid $8 per hour, including fringe benefits. Should an inspection station be established to test all units? Assume that the line will operate at the same rate (i.e., the current production rate) regardless of whether or not the inspection operation is added. a-1. Without the inspector, what is the current hourly cost of defects? a-2. Should an inspection station be established to test all units based on costs alone? multiple choice Yes No a-3. If the inspection operation is added, what would be the cost to inspect each unit? Note: Round your answer to 2 decimal places. b. What would be the benefit (or loss) from establishing the inspection process? Note: Round your answer…Performance Evaluation and Risk Aversion Jill Lewis is the office manager of PureBreds Inc.Her office has 30 employees whose collective job is to process applications by dog owners whowant to register their pets with the firm. There is never a shortage of applications waiting to be processed, but random events beyond Lewis’s control (e.g., employees out sick) cause fluctuations inthe number of applications that her office can process. Jill is aware that it is important that the applications be processed quickly and accurately. Alex Zale, the district manager to whom Jill reports,bases his evaluation of Jill on the number of applications that are processed.Required1. If Jill is risk averse, how should Alex compensate her? Why?a. Flat salary.b. Straight commission based on the number of applications processed.c. Flat salary with a bonus based on the number of applications processed.d. Flat salary with a bonus based on the firm’s earnings.2. What is a disadvantage of an evaluation method…4.
