Supply Chain Supply Chain ManagementManagement
Supply Chain Management is the Supply Chain Management is the management of the entire value-added management of the entire value-added chain, from the supplier to manufacturer chain, from the supplier to manufacturer right through to the retailer and the right through to the retailer and the final customer. SCM has three primary final customer. SCM has three primary goals: Reduce inventory, increase the goals: Reduce inventory, increase the transaction speed by exchanging data in transaction speed by exchanging data in real-time, and increase sales by real-time, and increase sales by implementing customer requirements implementing customer requirements more efficiently. more efficiently.

Due to infrastructure government infrastructure investments and decreases in Transportation cost, transportation cost is typically much less significant than theReductions in manufacturing. Inventory management has been the area of attention.
In-transit inventory or pipeline inventoryIn-transit inventory or pipeline inventory: : inventory that is in the process of movement inventory that is in the process of movement from point of receipt or production and from point of receipt or production and between points of storage and distribution. between points of storage and distribution.

Cycle InventoryCycle Inventory: the average amount of inventory used to satisfy : the average amount of inventory used to satisfy demand between receipt of supplier shipments. The size of the demand between receipt of supplier shipments. The size of the cycle inventory is a result of the production or purchase of cycle inventory is a result of the production or purchase of material in large lots. Companies produce or purchase in large material in large lots. Companies produce or purchase in large lots to exploit economies of scale in the production, lots to exploit economies of scale in the production, transportation, or purchasing process. With the increase in lot transportation, or purchasing process. With the increase in lot size, however, also comes an increase in carrying costs. The size, however, also comes an increase in carrying costs. The basic trade-off supply managers face is the cost of holding basic trade-off supply managers face is the cost of holding larger lots of inventory (when cycle inventory is high) versus the larger lots of inventory (when cycle inventory is high) versus the cost of ordering product frequently (when cycle inventory is cost of ordering product frequently (when cycle inventory is low). Some of this inventory may be in-transit, while some may low). Some of this inventory may be in-transit, while some may be inventory-at-rest.be inventory-at-rest.
Safety inventorySafety inventory: inventory held in case demand exceeds : inventory held in case demand exceeds expectation; it is held to counter uncertainty. If they have too expectation; it is held to counter uncertainty. If they have too much safety inventory, goods go unsold and may have to be much safety inventory, goods go unsold and may have to be discounted. If the company has ordered too little safety discounted. If the company has ordered too little safety inventory, however, the company will lose sales and the margin inventory, however, the company will lose sales and the margin those sales would have brought. Therefore, choosing safety those sales would have brought. Therefore, choosing safety inventory involves making a trade-off between the costs of inventory involves making a trade-off between the costs of having too much inventory and the costs of losing sales due to having too much inventory and the costs of losing sales due to not having enough inventory. Generally this inventory is not having enough inventory. Generally this inventory is inventory-at-rest, so that it is immediately available.inventory-at-rest, so that it is immediately available.
