1 Postponements is a method to delay ordering some portion of the demand 2 When ordering items in a group, an increase in the additional ordering cost of a particula item may result in a larger multiple of ordering periods for that item 3 Style goods equations are derived using the minimization of costs 4 The determination of order quantities when there is a declining demand pattern is based on historical demand 5 The order quantity is in part determined by the price of a style goods item 6 Including buyback in the contract will decrease the supplier's profit 7 The expected profit in a style goods problem depends in part on the standard deviation of historical demand 8 The two bin systems can be applied to slow moving items 9 C items should be ordered frequently to prevent shortages 10 When using a policy of only ordering full truckloads of multiple items, it is possible that n all items would be included in a particular order 11 As k increases, the Gu function also decreases 12 Ordering items in groups never results in an increase of average inventory levels 13 In an inflationary time, we usually order smaller quantities 14 Slow moving items are usually modeled with the Poisson distribution 15 Available space in a warehouse will impact the distribution of items that we order
