بشكل مختصر
مشروع تخرجي هو

inventory control for pharmacy department
to avoid shortage for medications (out of stocks ) by forecasting with arima method (minitab) software
and using the saftey stock and reorder point after the ABC analysis

i did the forecasting based on 2 years past by montlhy = 24 months
i know more years are better but those what are available
after the forecast i calculate the saftey stock and reorder point

saftey stock with this equation cause my demand is not normal ditribution
average demand calculated from the forecast for the 3rd year
max demand = biggest demand in the third year
lead time was about 2 months

Safety stock = (max demand - avergae demand) * lead time

reorder point = (average demand * lead time ) + SS

mu unit is units per month

my doctor said i should do the EOQ (economic ordr quantity )
but as i know it's for minimizing total inventory holding cost and ordering cost
and also it applies only when demand for the product is constant over the year and mine is not [wikipedia]

my facility is govermntal one and the carrying cost is not available and my demands are not in a normal distribution
my question are

are my steps till now right ? should i need to add something ?
can I apply the EOQ in my situation ?

please reply me as soon as possible
I will be
appreciated
