Explicit modeling of multi-period setup times in proportional lot-sizing and scheduling problem with variable capacity [PDF]
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]
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
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

Energy Implications of Lot Sizing Decisions in Refrigerated Warehouses
Cold supply chains (CSCs) are responsible for preserving the quality of perishable goods in storage and transport. They consume significant amounts of energy to maintain cooling temperatures constant over time continuously and ubiquitously, which is ...

SIMULTANEOUS PRICING AND LOT SIZING FOR A DETERIORATING PROCESS
This paper develops Banerjee’s model (2005), on concurrent pricing and lot sizing for a supplier on the bases of contractual agreement with a buyer, by considering condition that the supplier’s production system deteriorates over time/usage.

Sickle Cell Disease Is an Inherent Risk for Asthma in a Sibling Comparison Study
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 ...

Psychosocial Outcomes in Patients With Endocrine Tumor Syndromes: A Systematic Review
ABSTRACT Introduction The combination of disease manifestations, the familial burden, and varying penetrance of endocrine tumor syndromes (ETSs) is unique. This review aimed to portray and summarize available data on psychosocial outcomes in patients with ETSs and explore gaps and opportunities for future research and care.

Optimal selling price, replenishment lot size and number of shipments for two-echelon supply chain model with deteriorating items [PDF]
This paper deals with a pricing and production-distribution model for a deteriorating item in a two-echelon supply chain. The profit function for the manufacturer and retailer in the integrated supply chain is derived. The manufacturer's production batch
