Question

Meena Chavan Corp's computer chip production process yields DRAM chips with an average life of 2,000 hours and s = 120 hours. The tolerance upper and lower specification limits are 2,600 hours and 1,700 hours, respectively. Is this process capable of producing DRAM chips to specification?

Answer 1

To determine the capability of Meena Chavan Corp's production process for DRAM chips, one must calculate the process capability index (Cpk), which assesses if the process can produce output within given specification limits. The necessary data to calculate Cpk is provided, but the calculation is not performed in this summary.

Step-by-step explanation:

The capability of Meena Chavan Corp's process to produce DRAM chips within specifications can be assessed using process capability analysis. Process capability is the statistical measure of a process's ability to produce output within specification limits. The capability index, such as Cpk, can be calculated.

To calculate Cpk, you need the process mean (mu), the standard deviation (s), and the specification limits. Here, the process mean is given as 2,000 hours, s = 120 hours, and the specification limits are 2,600 hours for the upper limit and 1,700 hours for the lower limit.

The Cpk index is the minimum of the following two calculations: (USL -mu) / (3s) for the upper specification limit, and (mu - LSL) / (3s) for the lower specification limit. If the Cpk is higher than 1.33, the process is generally considered capable. However, since the exact Cpk value has not been provided in the question, we cannot conclusively determine the capability of the process without further calculation.
