Material theory (or more formally the mathematical theory of inventory and production) is the sub-specialty within operations research and operations management that is concerned with the design of production/inventory systems to minimize costs: it studies the decisions faced by firms and the military in connection with manufacturing, warehousing, supply chains, spare part allocation and so on ...
Steven Nahmias is an author and professor of operations management at Santa Clara University.He is best known for his contributions to inventory theory, and, in particular, perishable inventory theory.
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, [1] 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 ...
Typically, supply-chain managers aim to maximize the profitable operation of their manufacturing and distribution supply chain. This could include measures like maximizing gross margin return on inventory invested (balancing the cost of inventory at all points in the supply chain with availability to the customer), minimizing total operating expenses (transportation, inventory and ...
Inventory optimization refers to the techniques used by businesses to improve their oversight, control and management of inventory size and location across their extended supply network. [1] It has been observed within operations research that "every company has the challenge of matching its supply volume to customer demand.
He writes, "areas in need of an inventory can be identified through the use of predictive data". [3] Once the objectives for accuracy and methods of measuring have been established "the criteria need to be quantified. An overall measure of the inventory accuracy should be maintained as a management key performance indicator". [7]
Inventory Turn is a financial accounting tool for evaluating inventory and it is not necessarily a management tool. Inventory management should be forward looking. The methodology applied is based on historical cost of goods sold. The ratio may not be able to reflect the usability of future production demand, as well as customer demand.
Inventory theory indicates that maintaining inventories beyond immediate demand can yield advantages by curbing the bargaining power of suppliers. [2] This strategic action influences the supplier to impose higher prices during initial periods, capitalizing on the heightened demand resulting from building strategic inventories.
