Inventory analysis is one of the branches of Operation Research which deals in studying and understanding the stock/product mix combined with the knowledge of the demand for stock/product. It is the technique to determine the optimum level of inventory for a firm. [1] [2]
Finance is the study and discipline of money, currency and capital assets. It is related to, but not synonymous with economics,which is the study of production, distribution, and consumption of money, assets, goods and services . Finance activities take place in financial systems at various scopes, thus the field can be roughly divided into personal, corporate, and public finance.
In commerce, supply chain management (SCM) deals with a system of procurement, operations management, logistics and marketing channels so that the raw materials can be converted into a finished product and delivered to the end customer. A more narrow definition of the supply chain management is the "design, planning, execution, control, and monitoring of supply chain activities with the objective of creating net value, building a competitive infrastructure, leveraging worldwide logistics, synchronising supply with demand and measuring performance globally".This can include the movement and storage of raw materials, work-in-process inventory, finished goods, and end to end order fulfilment from the point of origin to the point of consumption. Interconnected, interrelated or interlinked networks, channels and node businesses combine in the provision of products and services required by end customers in a supply chain.
Inventory or stock refers to the goods and materials that a business holds for the ultimate goal of resale, production or utilisation.
The point of sale (POS) or point of purchase (POP) is the time and place at which a retail transaction is completed. At the point of sale, the merchant calculates the amount owed by the customer, indicates that amount, may prepare an invoice for the customer, and indicates the options for the customer to make payment. It is also the point at which a customer makes a payment to the merchant in exchange for goods or after provision of a service. After receiving payment, the merchant may issue a receipt for the transaction, which is usually printed but can also be dispensed with or sent electronically.
The beer distribution game is an educational game that is used to experience typical coordination problems of a supply chain process. It reflects a role-play simulation where several participants play with each other. The game represents a supply chain with a non-coordinated process where problems arise due to lack of information sharing. This game outlines the importance of information sharing, supply chain management and collaboration throughout a supply chain process. Due to lack of information, suppliers, manufacturers, sales people and customers often have an incomplete understanding of what the real demand of an order is. The most interesting part of the game is that each group has no control over another part of the supply chain. Therefore, each group has only significant control over their own part of the supply chain. Each group can highly influence the entire supply chain by ordering too much or too little which can lead to a bullwhip effect. Therefore, the order taking of a group also highly depends on decisions of the other groups.
Reverse logistics encompasses all operations related to the upstream movement of products and materials. It is "the process of moving goods from their typical final destination for the purpose of capturing value, or proper disposal. Remanufacturing and refurbishing activities also may be included in the definition of reverse logistics." Growing green concerns and advancement of green supply chain management concepts and practices make it all the more relevant. The number of publications on the topic of reverse logistics have increased significantly over the past two decades. The first use of the term "reverse logistics" in a publication was by James R. Stock in a White Paper titled "Reverse Logistics," published by the Council of Logistics Management in 1992. The concept was further refined in subsequent publications by Stock (1998) in another Council of Logistics Management book, titled Development and Implementation of Reverse Logistics Programs, and by Rogers and Tibben-Lembke (1999) in a book published by the Reverse Logistics Association titled Going Backwards: Reverse Logistics Trends and Practices. The reverse logistics process includes the management and the sale of surplus as well as returned equipment and machines from the hardware leasing business. Normally, logistics deal with events that bring the product towards the customer. In the case of reverse logistics, the resource goes at least one step back in the supply chain. For instance, goods move from the customer to the distributor or to the manufacturer.
A minibar is a small refrigerator, typically an absorption refrigerator, in a hotel room or cruise ship stateroom. The hotel staff fill it with drinks and snacks for the guest to purchase during their stay. It is stocked with a precise inventory of goods, with a price list. The guest is charged for goods consumed when checking out of the hotel. Some newer minibars use infrared or other automated methods of recording purchases. These detect the removal of an item, and charge the guest's credit card right away, even if the item is not consumed. This is done to prevent loss of product, theft and lost revenue.
Safety stock is a term used by logisticians to describe a level of extra stock that is maintained to mitigate risk of stockouts caused by uncertainties in supply and demand. Adequate safety stock levels permit business operations to proceed according to their plans. Safety stock is held when uncertainty exists in demand, supply, or manufacturing yield, and serves as an insurance against stockouts.
Inventory control or stock control can be broadly defined as "the activity of checking a shop's stock". It is the process of ensuring that the right amount of supply is available within a business. However, a more focused definition takes into account the more science-based, methodical practice of not only verifying a business's inventory but also maximising the amount of profit from the least amount of inventory investment without affecting customer satisfaction. Other facets of inventory control include forecasting future demand, supply chain management, production control, financial flexibility, purchasing data, loss prevention and turnover, and customer satisfaction.
Consignment is a process whereby a person gives permission to another party to take care of his property and retains full ownership of the property until the item is sold to the final buyer. It is generally done during auctions, shipping, goods transfer, or putting something up for sale in a consignment store. The owner of the goods pays the third-party a portion of the sale for facilitating the sale. Consignors maintain the rights to their property until the item is sold or abandoned. Many consignment shops and online consignment platforms have a set day limit before an item expires for sale. Within the time of contract, reductions of the price are common to promote the sale of the item, but vary on the type of item sold (usually 60–90 days).
The business terms push and pull originated in logistics and supply chain management, but are also widely used in marketing and in the hotel distribution business.
Scan-based trading (SBT) is the process where suppliers maintain ownership of inventory within retailers' warehouses or stores until items are scanned at the point of sale. Suppliers, such as manufacturers or farmers, own the product until it is purchased by the customer, with the store or venue then buying the product from the supplier and reselling it to the customer. Analysts in the grocery sector estimate scan-based trading accounted for $21 billion dollars in consumer goods purchased in the grocery industry alone in 2020, or nearly 3% of overall sales.
In accounting, the inventory turnover is a measure of the number of times inventory is sold or used in a time period such as a year. It is calculated to see if a business has an excessive inventory in comparison to its sales level. The equation for inventory turnover equals the cost of goods sold divided by the average inventory. Inventory turnover is also known as inventory turns, merchandise turnover, stockturn, stock turns, turns, and stock turnover.
Field inventory management commonly known as inventory management is the function of understanding the stock mix of a company and the different demands on that stock. The demands are influenced by both external and internal factors and are balanced by the creation of purchase order requests to keep supplies at a reasonable or prescribed level. Inventory management is important for every other business enterprise.
Overstock, excessive stock, excess2sell, B-stock, or excess inventory, is the result of poor management of stock demand or of material flow in process management. Excessive stock is also associated with loss of revenue owing to additional capital bound with the purchase or simply storage space taken. Excessive stock can result from over delivery from a supplier or from poor ordering and management of stock by a buyer for the stock.
Work in process (WIP), work in progress (WIP), goods in process, or in-process inventory refers to a company's partially finished goods waiting for completion and eventual sale, or the value of these items. The term is used in supply chain management, and WIP is a key input for calculating inventory on a company's balance sheet.
In marketing, carrying cost, carrying cost of inventory or holding cost refers to the total cost of holding inventory. This includes warehousing costs such as rent, utilities and salaries, financial costs such as opportunity cost, and inventory costs related to perishability, shrinkage (leakage) and insurance. Carrying cost also includes the opportunity cost of reduced responsiveness to customers' changing requirements, slowed introduction of improved items, and the inventory's value and direct expenses, since that money could be used for other purposes. When there are no transaction costs for shipment, carrying costs are minimized when no excess inventory is held at all, as in a Just In Time production system.
Google Ad Manager is an ad exchange platform introduced by Google on June 27, 2018. It combines the features of two former services from Google's DoubleClick subsidiary, DoubleClick for Publishers and DoubleClick Ad Exchange (AdX). Google Ad Manager initially used a second-price auction format, before announcing that it would be replaced with a first-price auction format in March 2019. Google Ad Manager is the free version of this online ad management software and it is recommended for small businesses. Google Ad Manager 360 is the paid version. Google Ad Manager does not require a minimum amount of impressions on individual active ads, but it does have a limit of 200 million impressions per month. Google Ad Manager manages inventory for advertisers, publishers and ad servers. Advertisers are able to manage their inventory of ad creative, publishers are able to manage their ad space inventory, and ad servers can use the platform to determine which ad to serve and where to serve it. Additionally, Google Ad Manager can use data collected from ad performance and ad space performance to make suggested optimizations to the user. These optimizations suggest what the user could change to better reach the goals they have set for a particular campaign.
Inventory management software is a software system for tracking inventory levels, orders, sales and deliveries. It can also be used in the manufacturing industry to create a work order, bill of materials and other production-related documents. Companies use inventory management software to avoid product overstock and outages. It is a tool for organizing inventory data that before was generally stored in hard-copy form or in spreadsheets.
Inventory optimization is a method of balancing capital investment constraints or objectives and service-level goals over a large assortment of stock-keeping units (SKUs) while taking demand and supply volatility into account.
