CPR Model and Bullwhip Effect

CPFR (Collaborative Planning, Replenishment, and Forecasting) is a growingly applied business practice aiming to lower supply chain spending through the promotion of increased cooperation, integration, and visibility between supply chains of trading partners. The phrase "trading partner" is applicable to nearly all combinations (inter, as well as intra) of manufacturers, suppliers, retailers, or distributors. CPFR itself represents an extension of older collaboration efforts such as just-in-time (JIT) (Andrews, 2008). CPFR defines a broad framework including the components of planning, strategizing, supply and demand management, implementation, and appraisal. The strategizing and planning phase includes developing joint business strategies and collaboration terms. Supply and demand management concentrates on order planning and forecasting. Implementation entails generating and meeting replenishment orders. Lastly, appraisal deals with score carding and exception management processes (Andrews, 2008).

Bullwhip Effect

A firm that wishes to last in the current competitive environment must develop strong supply chains capable of responding rapidly to consumer requirements. Meanwhile, supply chains today are vulnerable to uncertainties that have negative ripple effects when going upstream in a supply chain. Availability of data pertaining to inventory levels, demand, lead times, price, etc. can help reduce uncertainties in supply chains. Furthermore, such access can help alleviate bullwhip effect-related issues. The aforementioned 'bullwhip effect' refers to a phenomenon wherein order sequence variations increase for suppliers (positioned farthest from end customers). Industry observations like simulated experiments (e.g., Beer Game) and macroeconomic data have depicted enormous added supply chain expenses owing to bullwhip (Kazemi & Zhang, 2013).

Mitigation

Bullwhip effect can be mitigated by information sharing, as it introduces a measure of transparency and coordination across the supply chain and allows facilitate efficient allocation of inventories across different stages of the supply chain. Literature cites a wide range of information sharing benefits, which are predominantly dependent on the stage in the chain and the demand market situation.

Information sharing not only decreases bullwhip effect (i.e., order fluctuation) in the chain, but adds value to it as well. Numerous researchers have strived to measure (measure) supply-chain VOI (value of information sharing), defined generally as supply chain expenditure ratio with and without the information sharing component. A majority of innovative practices of chain coordination indeed rely on processes, product, and design of supply chain. In the last few decades, different methods like CPFR and VMI (Vendor Managed Inventory insert full form) have helped implement multiple collaborative approaches via VMI (Kazemi & Zhang, 2013).

Relevance of VMI (Vendor Managed Inventory)

VMI denotes a strategy in supply chains wherein the supplier or vendor is charged with management of retailer or customer stock. This concept was first successful during the late eighties when deployed between P&G and Wal-Mart, and ever since, other businesses like Johnson & Johnson, Shell Chemical and Campbell Soup have adopted this strategy. As retailers do not have to place orders under this practice, retailer ordering costs are eliminated, with the supplier being made responsible for replenishing inventories. This implies reduction in administration expenses for retailers, together with decreased delivery expenditures for vendors. Shifting ordering responsibility to vendors means they need to adapt their activities to the factor of customer service. It is demonstrated that VMI implementation helps reduce occurrence of stock-outs, improves customer service, and lowers costs associated with inventory turnover growth and decreased safety stock levels. VMI systems' deterministic model for examining VMI program cost-savings revealed that, with increased ratio of manufacturer-to-retailer inventory replenishment lead-time or inventory-holding cost ratio, overall holding cost-reductions will increase for manufacturers (Kazemi & Zhang, 2013).
