Inventory Control
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. An extension of inventory control is the inventory control system. This may come in the form of a technological system and its programmed software used for managing various aspects of inventory problems, or it may refer to a methodology (which may include the use of technological barriers) for handling loss preve ...

Supply Chain Management
In commerce, supply chain management (SCM) is the management of the flow of goods and services including all processes that transform raw materials into final products between businesses and locations. 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. Supply-chain management has been defined as 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". SCM practice draws heavily on industrial engineering, systems engineering, operations management, logis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vendor Managed Inventory
Vendor-managed inventory (VMI) is an inventory management practice in which a supplier of goods, usually the manufacturer, is responsible for optimizing the inventory held by a distributor. In traditional inventory management, a retailer (sometimes called distributor or buyer) makes his or her own decisions regarding the order size. Under VMI, the retailer shares their inventory data with a vendor (sometimes called supplier) such that the vendor is the decision-maker who determines the order size. Thus, the vendor is responsible for the retailer's ordering cost, while the retailer has to pay for their own holding cost. This policy can prevent stocking undesired inventories and hence can lead to an overall cost reduction. Moreover, the magnitude of the bullwhip effect is also reduced by employing the VMI approach in a buyer-supplier cooperation. A third-party logistics provider may also be involved to make sure that the buyer has the required level of inventory by adjusting the dem ...

Inventory Optimization
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. Inventory management challenges Every company has the challenge of matching its supply volume to customer demand. How well the company manages this challenge has a major impact on its profitability. In contrast to the traditional "binge and purge" inventory cycle in which companies over-purchase product to prepare for possible demand spikes and then discards extra product, inventory optimization seeks to more efficiently match supply to expected customer demand. APQC Open Standards data shows that the median company carries an inventory of 10.6 percent of annual revenues as of 2011. The typical cost of carrying inventory is at least 10.0 percent of the inventory value. So the median company spends over 1 percent of revenues carrying inventory, although for ...

Stock Management
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. Retail supply chain Inventory management in the retail supply chain follows the following sequence: # Request for new stock from stores to head office, # Head office issues purchase orders to the vendor, # Vendor ships the goods, # Warehouse receives the goods, # Warehouse stores and distributes to the stores, # Shops and/or consumers (e.g. wholesale shops) receive the goods, # Goods are sold to customers at the shops. Software applications SaaS inventory management software is a tool to help efficiently manage stock. While the capabilities of applications vary, most i ...

Storage Management System
Hierarchical storage management (HSM), also known as Tiered storage, is a data storage and Data management technique that automatically moves data between high-cost and low-cost storage media. HSM systems exist because high-speed storage devices, such as solid state drive arrays, are more expensive (per byte stored) than slower devices, such as hard disk drives, optical discs and magnetic tape drives. While it would be ideal to have all data available on high-speed devices all the time, this is prohibitively expensive for many organizations. Instead, HSM systems store the bulk of the enterprise's data on slower devices, and then copy data to faster disk drives when needed. The HSM system monitors the way data is used and makes best guesses as to which data can safely be moved to slower devices and which data should stay on the fast devices. HSM may also be used where more robust storage is available for long-term archiving, but this is slow to access. This may be as simple as an of ...

Scan-based Trading
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. History Traditionally scan-based trading programs use electronic data interchange solutions as the key component to synchronize information on store locations (Organizational Structure 816), items (Price/Sales Catalog 832), daily sales (Product Activity Data 852), receivings (Receiving Advice 861), billings (Invoice 810) and payments (Remittance Advice 820) between a retailer and its Scan-Based Trading suppliers.

Newsvendor Model
The newsvendor (or newsboy or single-periodWilliam J. Stevenson, Operations Management. 10th edition, 2009; page 581 or salvageable) model is a mathematical model in operations management and applied economics used to determine optimal inventory levels. It is (typically) characterized by fixed prices and uncertain demand for a perishable product. If the inventory level is q, each unit of demand above q is lost in potential sales. This model is also known as the ''newsvendor problem'' or ''newsboy problem'' by analogy with the situation faced by a newspaper vendor who must decide how many copies of the day's paper to stock in the face of uncertain demand and knowing that unsold copies will be worthless at the end of the day. History The mathematical problem appears to date from 1888 where Edgeworth used the central limit theorem to determine the optimal cash reserves to satisfy random withdrawals from depositors. According to Chen, Cheng, Choi and Wang (2016), the term "newsb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economic Order Quantity
Economic Order Quantity (EOQ), also known as Economic Buying Quantity (EPQ), is the order quantity that minimizes the total holding costs and ordering costs in inventory management. It is one of the oldest classical production scheduling models. The model was developed by Ford W. Harris in 1913, but R. H. Wilson, a consultant who applied it extensively, and K. Andler are given credit for their in-depth analysis. Overview EOQ applies only when demand for a product is constant over the year and each new order is delivered in full when inventory reaches zero. There is a fixed cost for each order placed, regardless of the number of units ordered; an order is assumed to contain only 1 unit. There is also a cost for each unit held in storage, commonly known as holding cost, sometimes expressed as a percentage of the purchase cost of the item. While the EOQ formulation is straightforward there are factors such as transportation rates and quantity discounts to consider in actual applicatio ...

Economic Lot Scheduling Problem
The economic lot scheduling problem (ELSP) is a problem in operations management and inventory theory that has been studied by many researchers for more than 50 years. The term was first used in 1958 by professor Jack D. Rogers of Berkeley, who extended the economic order quantity model to the case where there are several products to be produced on the same machine, so that one must decide both the lot size for each product and when each lot should be produced. The method illustrated by Jack D. Rogers draws on a 1956 paper from Welch, W. Evert. The ELSP is a mathematical model of a common issue for almost any company or industry: planning what to manufacture, when to manufacture and how much to manufacture. Model formulation The classic ELSP is concerned with scheduling the production of several products on a single machine in order to minimize the total costs incurred (which include setup costs and inventory holding costs). We assume a known, non-varying demand d_j, j=1,\cdots,m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
