WebAug 31, 2024 · The production and outsourcing costs are fixed-plus-linear, and the inventory and backlogging costs are linear. We establish a mathematical programming model … WebThe dynamic lot-size model in inventory theory, is a generalization of the economic order quantity model that takes into account that demand for the product varies over time. The model was introduced by Harvey M. Wagner and Thomson M. Whitin in 1958. [1] [2]

WebDownloadable! Efficient algorithms for the economic lot-sizing problem with storage capacity are proposed. On the one hand, for the cost structure consisting of general linear holding and ordering costs and fixed setup costs, an O T 2 dynamic programming algorithm is introduced, where T is the number of time periods. The new approach induces an … WebFeb 1, 2024 · In this article we study a classical single-item economic lot-sizing problem, where production cost functions are assumed to be piecewise linear. ...
