Summary Introduction
Interpretation:Compare the lot-for-lot
Concept Introduction:Lot-for-lot scheduling is one of the dynamic lot sizing techniques utilized in MRP for determining optimum order quantity which should be the same as the required quantity.This is utilized when it is required to determine lot quantities in each period and also maintaining a safety stock.
Other comparable techniques are also available.

- Montague Composite makes a unit A, which consists of two units of B, three units of C, and four units of D. C is composed of three units of D and two units of E. Items A, C, D and E have on-hand inventories of 10, 20, 30 and 40 units respectively. Item B has a scheduled receipt of 50 units in period 1, and C has a scheduled receipt of 90 units in period 1. Lot-for-lot sizing is used for items A and B. Item C requires a minimum lot size of 60 units. D and E must be purchased in multiples of 35 and 55 respectively. Lead times are one period for items A, B and C, and two periods for items D and E. The gross requirements for A are 180 in period 5, and 220 in period 8.

You have been given the job of coordinating distribution of the latest model, the Superslide, to outlets in Lake Tahoe and Whistler. The Portland plant, when operating at full capacity, can manufacture 620 pairs Superslide skis per week, while the Toronto plant, beset by labor disputes, can produce only 410 pair of skis per week. The outlet in Lake Tahoe orders at least 500 pairs Superslide skis per week, while Whistler orders at least 530 pairs of skis per week.
