Q$1.$ Explain the term 'manufacturing systems?

Q$2.$ What do you mean by flexible manufacturing system $($FMS$)?$ What are the components of FMS$?$

Q$3.$ Using the data in the table, answer the following problems.

$\backslash$table$[[$Month $($t$),1,2,3,4,5,6,7,8,9,10,11,12],[$Demand $(D_t),670,698,740,805,879,940,870,778,912,940,809,-]]$

Forecast the demand for the periods with the three$-$period weighted moving average method. The most recent data should be given $50$ per cent weightage, second year past data $30$ per cent, and third year past data $20$ per cent. Also, compare the result with the result of three$-$period simple moving average graphically.

Forecast the demand for the periods using the exponential smoothing method $(=0\mathrm{.}3$ and $=0\mathrm{.}5.$ Also, compare the results graphically.

Forecast the demand for the periods with adjusted exponential smoothing method and $=0\mathrm{.}3.$ Also, compare the result graphically with simple exponential smoothing $0\mathrm{.}5$
