To calculate the MPS quantities, add the lot size and safety stock to the forecasted demand, and subtract the on-hand inventory. So the MPS quantity for the first period is 55.
The MPS (Master Production Schedule) quantities can be calculated by considering the lot size, safety stock, and on-hand inventory. In this case, the lot size is 100 and the safety stock is 15.
To calculate the MPS quantities, first determine the projected demand for each period by adding the lot size and safety stock to the forecasted demand. Then, subtract the on-hand inventory from the projected demand to get the MPS quantity.
For example, in the first period, the forecasted demand is 150. Adding the lot size and safety stock, we get 100 + 15 = 115. Subtracting the on-hand inventory of 60, we get 115 - 60 = 55. So the MPS quantity for the first period is 55.
