QUESTIONS

Please write basicly the steps of "Making Cake" by categorizing them considering the pyramidal structure of work: Task$-$Work Elements$-$Basic Motion Elements $($using therbligs$).$ Also use Activity Chart Shadings for your steps.

Read the sentences below, carefully. If you think the sentence is True or False, then write $($T$)$ or $($F$)$ inside the paranthesis. Also, if you think that a sentence is False, then write the truth of it$.$

$()$ Gantt Chart is an activity chart type.

$()$ Interruptions in a process are examples of fatigue allowances.

$()$ PDCA means "Planning, Documenting, Classifying Allowances".

$()$ Required time for a work element is six seconds or longer.

$()$ Fake and effect diagram is a data collection and analysis tool.

The normal time to perform a certain manual work cycle is $5\mathrm{.}20$ min $.$ In addition, an irregular work element whose normal time is $5\mathrm{.}55$ min $.$ must be performed every $10$ cycles. One work unit is produced each cycle. The PFD allowance factor is $14\%.$

a$)$ Determine the standard time per piece.

b$)$ How many work units are produced during an $8-$hour shift at $100\%$ performance, when we include allowances?

c$)$ If the actual cycle time of a worker is estimated as $4\mathrm{.}80$ min $.$ per piece and if he works $7\mathrm{.}2$ hours during a regular shift, how many units are produced by the worker?

d$)$ Calculate the actual output in terms of standard hours.

e$)$ Find the worker efficiency.

The Formulas:

$T_c=\frac{T_n}{P_w}$

$T_{std}=T_n(1+A_{pfd})$

$H_{std}=Q^{**}{T}_{std}$

$E_w=\frac{H_{std}}{H_{sh}}$

Please write the general names of activities for each step considering process chart of right$-$hand$/$left$-$hand, given below

a$)$ Make comments on the general process:

If the method is the best or it must be improved? If it needs to be improved, then explain that which steps to be followed, which questions to be asked,etc.

b$)$ Propose alternatives to improve the method if you think an prove that it is not a good method.

$5.$ Please write the long $($full$)$ forms of the abbreviations below:

TPM$,$ MRPI, MRPII, SMED, BOM, CPM$,$ DC$,$ wip $,$ ERP, $5$S$.$
