1..Suppose that you have a deterministic demand pattern for the next 12 months in which the demand quantities vary from month to month. How would you determine whether it was worthwhile to use the methods for time-varying demand (Such as Silver-Meal, LUC or PPB heuristics) to determine order quantities or to use the basic EOQ model where demand is assumed to assumed to occur at a constant rate

2.Explain why planned backorders could further reduce total costs even in situations where demand and lead times are deterministic?

3. Explain the following strategies can help a firm further reduce its supply chain risk beyond simply holding additional safety stock of critical items
