Some suppliers send their customers a prior notification of the shipment to inform them of an incoming order known as EDI 856. The customer can also benefit from a reduction in purchase costs. Because the lender receives data, not orders, the purchasing service must spend less time calculating and producing orders. The search for better coordination systems is essential to enable modern supply chains to survive in a highly competitive environment. A supply chain can use revenue participation, information exchange and quantity discounts, etc., to obtain this viable advantage. Another current trend is to store the creditor stock in the buyer`s warehouse, which is called sales management inverrification (VMI) with consignment agreement (CS). This paper brings the current literature in VMI closer to real-life consignment stocks by introducing the concept of screening defective items. A single buyer supply chain is considered when the customer supplies each batch of production in batches to the buyer`s warehouse. The buyer removes these products and verifies them while meeting market demand. An analytical model is developed to present this scenario.

The impact of different groups of defective items, storage costs and disposal systems are also examined. The results indicate that the importance of the proposed storage regime relative to traditional regulations remains proportional to the size and number of lots in a cycle. In addition, the non-financial component of storage costs has a significant impact on supply chain costs. The lender-managed inventory model has enabled companies to offer an effective turnover rate and an effective level of profit. The model was first tested in the 1980s by Walmart and Procter and Gamble. Their vendor-managed inventory strategy has enabled Walmart to be the largest retailer in the world. The VMI model with CS agreement for a two-tier supply chain is under development. Vendor Managed Inventory or VMI is a process in which the lender creates orders for its debtors based on the information on the needs it receives from the Debitor. The lender and the debtor are bound by an agreement that determines inventories, filling rates and costs. The manufacturer is aware of the distributor`s inventory and sales figures because the company`s business resource planning systems are linked.

Orders are established and inventories are managed by the manufacturer at agreed levels. Retailers such as Walmart use vendor-managed inventory with great success. A storage contract managed by the creditor is a simple way to ensure that stocks arrive on time in the factory lobby. Read 3 min As a manufacturer has more visibility for customer stocks, it is easier to make sure there are no stocks because they can see when to produce items. With the common business model, the distributor or distributor orders a product from the manufacturer. This gives the merchant control over the size and delivery of the order. The vendor-managed inventory system connects the distributor and distributor via an Internet connection or EDI.
