Part A

$1.$Use simple linear regression and two decomposition methods to forecast monthly demand for both products in $2023.$ Which method would you recommend? This forecast will serve as the basis for sales and operations planning.

$2.$ Develop monthly sales and operations plans for $2023$ using the two production techniques $($level and chase$).$ Which technique is better?

Part B:

Calculate economic order and periodic order quantities for the final product of Mid$-$Sized Front$-$line tillers. $($use the prediction of average demand for Mid$-$Sized Front$-$line tillers for the year $2023$ developed in Part I. Assume that the holding cost is $25\%$ of the price $($$$10000)$ and the ordering cost is $ $3500.4.$ Prepare a master production schedule for the next six months of the year $2023$ using the economic order and periodic order quantities calculated in question $3.$

$5.$ Develop MRP computing the planned orders release, planned orders received, inventory, etc. for each material in the BOM $($use the prediction of average demand for Mid$-$Sized Front$-$line tillers year $2023$ developed in Part I; Lot size $=$ PPB for the Handlebar and Gearbox housing; Lot size $=$ L$4$L for the other components$).$ Note that the purchase costs are $$1200$ and $$200$ for the handlebar and Gearbox housing, respectively. Ordering cost is $$3500.6.$ Assume that the final product of Mid$-$Sized Front$-$line tillers, wheels, and engine assembly are fabricated in the following work centers, listed with accompanying time requirements as in the last table.
