When is Cpk = Cpu = Cpl = Cp?

Expert Solution

Cpk = Cpu = Cpl = Cp when the mean is centered between Upper Specification Limit USL and Lower Specification limit LSL

Cp =

When Mean is centered between USL and LSL, USL - = - LSL

Cpu =

USL = 3 * Cpu +

Cpl =

LSL = - 3 * Cpl

Cpk = min (, )

As seen from above, when USL - = - LSL, Cpu = Cpl = Cpk

Similarly, Cp = = =

However, Cpu = Cpl, Cp = = Cpu

Hence, Cp = Cpu

Thus, Cpk = Cpu = Cpl = Cp

Process Capability (Cpk and Cp) The operations manager of an insurance claims- processing department wants to determine the claims-processing capability of the department. Claims usually take a minimum of four days to handle. The company has a commitment to handle all claims within 10 days. On the 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...

1. CPK and SGOT tests are used in the diagnosis of myocardial infarction (MI). When the CPK test is given to a patient who does not have a MI, the probability of a negative finding (i.e. its specificity) is 0.6. The probability that the SGOT test will be negative for a non-MI patient is 0.7. When both tests are given to a non-MI patient the probability that at least one is negative is 0.9. For a non-MI patient who has...

When is an external interrupt recognized by the CPU? When more than one interrupt occurs, what approaches would you use to service them? What approaches should be taken when an interrupt occurs within an interrupt service routine Consider a hypothetical microprocessor having 64-bit instructions composed of two fields: the first 16-bits contains the op-code and the remainder the immediate operand or an operand address. Assume memory is organized in 32-bit words, i.e. one r/w access can yield a maximum of 32 bits. ...
