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 ...

Its is a class of inventory control models that generalize and combine elements of both the Economic Order Quantity (EOQ) model and the base stock model. [2] The (Q,r) model addresses the question of when and how much to order, aiming to minimize total inventory costs, which typically include ordering costs, holding costs, and shortage costs.
To satisfy the demand for period 1, 2, 3 Producing lot 1, 2 and 3 in one setup give us an average cost: = + + The average cost =( the setup cost + the inventory holding cost of the lot required in period 2+ the inventory holding cost of the lot required in period 3) divided by 3 periods.
The EPQ model was developed and published by E. W. Taft, a statistical engineer working at Winchester Repeating Arms Company in New Haven, Connecticut, in 1918. [1] This method is an extension of the economic order quantity model (also known as the EOQ model). The difference between these two methods is that the EPQ model assumes the company ...
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 ...
Jack D. Rogers (1919 – January 15, 2002) was an American management scientist, and Professor Emeritus in the Haas School of Business at the University of California, Berkeley, who coined the term Economic lot scheduling problem in 1958. [1] [2]
Techno-economic assessment or techno-economic analysis (abbreviated TEA) is a method of analyzing the economic performance of an industrial process, product, or service. The methodology originates from earlier work on combining technical, economic and risk assessments for chemical production processes. [ 1 ]
