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 $\%\text{'}$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.

Flag question: Spacer

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.$$ Use the elemental standard times that you calculated $($which were in minutes$)$ to determine a value for L & W for this calculation. Assume an automatic machine cycle time $($M$)$ of $3\mathrm{.}0$ minutes. The operator is paid $$12\mathrm{.}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.$$
