Modeling Multi-Plant Capacitated Lot Sizing Problem with Interplant Transfer [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2021 Lot sizing models involve operational and tactical decisions. These decisions may entail multi-level production processes such as assembly operations with multiple plants and limited capacities.

A study of the lot-sizing polytope [PDF]
Mathematical Programming, 2004 This is an analysis of the convex hull of feasible solutions \(F\) of the lot-sizing problem in bottleneck flow formulation. First, it is shown that the convex hull of \(F\) is full dimensional and trivial facets are given. Then the authors define bottlenecks of sets \(S\) and bottleneck covers to introduce bottleneck cover inequalities (BCI).

Reformulated Silver-Meal and Similar Lot Sizing Techniques
Axioms, 2023 Literature and most textbooks around the world describe Silver-Meal in such a way that periods with zero demand make Silver-Meal suggest a higher frequency of order replenishments than necessary and therefore higher total costs than necessary.

JOINT EFFCET OF FORECASTING AND LOT-SIZING METHOD ON COST MINIMIZATION OBJECTIVE OF A MANUFACTURER: A CASE STUDY [PDF]
Applied Computer Science, 2020 Forecasting and lot-sizing problems are key for a variety of products manufactured in a plant of finite capacity. The plant manager needs to put special emphasis on the way of selecting the right forecasting methods with a higher level of accuracy and to

Management Science, 1982 In this Note we present an alternative formulation to the MRP lot sizing model of Steinberg and Napier (SN) (Steinberg, E., H. A. Napier. 1980. Optimal multi-level lot sizing for requirements planning systems. Management Sci. 26 (2) 1258–1271.). The alternative is more parsimonious and the notation less cumbersome.

Fuzzy Mathematical Model For A Lot-Sizing Problem In Closed-Loop Supply Chain [PDF]
Journal of Optimization in Industrial Engineering, 2018 The aim of lot sizing problems is to determine the periods where production takes place and the quantities to be produced in order to satisfy the customer demand while minimizing the total cost.

Optimizing Supplier Selection and Order Lot-Sizing Decisions in a Two-Stage Supply Chain
Axioms, 2023 This paper analyzes different lot-sizing policies for the supplier selection and order allocation problem in a two-stage supply chain. The supply chain consists of multiple candidate suppliers and a single buyer.
