Retailer’s lot-sizing policy under two warehouses and two levels of delay permitted using algebraic method [PDF]
Yugoslav Journal of Operations Research, 2007 The main purpose of this paper is to modify Huang’s model [13] by considering two warehouses. In addition, we try to use algebraic method to determine the optimal lot-sizing policy for the retailer under two warehouses and two levels of delay permitted ...

Explicit modeling of multi-period setup times in proportional lot-sizing and scheduling problem with variable capacity [PDF]
Archives of Control Sciences, 2021 Small bucket models with many short fictitious micro-periods ensure high-quality schedules in multi-level systems, i.e., with multiple stages or dependent demand. In such models, setup times longer than a single period are, however, more likely.

On the equivalence of strong formulations for capacitated multi-level lot sizing problems with setup times [PDF]
, 2012 Several mixed integer programming formulations have been proposed for modeling capacitated multi-level lot sizing problems with setup times. These formulations include the so-called facility location formulation, the shortest route formulation, and the ...

A Polyhedral Study of the Static Probabilistic Lot-Sizing Problem
, 2016 We study the polyhedral structure of the static probabilistic lot-sizing problem and propose valid inequalities that integrate information from the chance constraint and the binary setup variables. We prove that the proposed inequalities subsume existing

Sickle Cell Disease Is an Inherent Risk for Asthma in a Sibling Comparison Study
Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction Sickle cell disease (SCD) and asthma share a complex relationship. Although estimates vary, asthma prevalence in children with SCD is believed to be comparable to or higher than the general population. Determining whether SCD confers an increased risk for asthma remains challenging due to overlapping symptoms and the ...
