Use the data below to answer the question "Calculate Standard Times" (you will not provide your answer in this section, but you will in the questions that follow)

A time study was performed on a process that consists of the following elements: operator removes a machined part from a milling machine (and sets it on an inspection bench), the operator then adjusts machine for the next milling cycle, loads the machine with the next part and starts an automatic cycle, and finally inspects the previously completed part (while the machine is running. Times are in minutes. Note the observed time has already been calculated into a "normal time" NT, so no performance ratings are given or necessary. Allowance %'s for each element are provided in the table.

In the "Calculate Standard Times" group of questions, you will enter the standard time calculated for each of the 4 elements from the table below.

Elemental Standard time

Using the calculated standard times from the previous time study data problem, find the optimal number of machines that should be assigned to an operator. Use the elemental standard times that you calculated (which were in minutes) to determine a value for L & W for this calculation. Assume an automatic machine cycle time (M) of 3.0 minutes. The operator is paid $12.00/h and the machines cost $42/hr to run.

Determine the value for "N" as well as the unit cost per part for the two assignment alternatives.

Enter total expected cost (TEC) per part for N rounded down (the lower machine count of the 2 alternatives)

Enter total expected cost (TEC) for N rounded up (the higher machine count of the 2 alternative)

Enter a value calculated for "N"
