Fuzzy modeling approach to on-hand stock levels estimation in (R, S) inventory system with lost sales

Guijarro, Ester; Babiloni, Eugenia; Canós-Darós, … - In: Journal of Industrial Engineering and Management (JIEM) 13 (2020) 3, pp. 464-474

Purpose: One challenge in inventory control models is to know the stock available at the beginning of the cycle to satisfy future demands, i.e. to know the on-hand stock levels at order delivery. For inventory managers, this knowledge is necessary to both determine service levels and establish...

Using chebyshev polynomials to approximate partial differential equations

Caporale, Guglielmo Maria; Cerrato, Mario - 2008

This paper suggests a simple method based on a Chebyshev approximation at Chebyshev nodes to approximate partial differential equations. It consists in determining the value function by using a set of nodes and basis functions. We provide two examples: pricing a European option and determining...
