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

open access: yesArchives 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.

Energy Implications of Lot Sizing Decisions in Refrigerated Warehouses

open access: yesEnergies, 2020
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 ...

A Polyhedral Study of the Static Probabilistic Lot-Sizing Problem

open access: yes, 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

SIMULTANEOUS PRICING AND LOT SIZING FOR A DETERIORATING PROCESS

open access: yesJurnal Ilmiah Teknik Industri, 2006
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.

Unitary Owen Points in Cooperative Lot-Sizing Models with Backlogging

open access: yesMathematics, 2021
This paper analyzes cost sharing in uncapacitated lot-sizing models with backlogging and heterogeneous costs. It is assumed that several firms participate in a consortium aiming at satisfying their demand over the planning horizon with minimal operating ...

Effects of Cancer Treatment on Somatosensory and Nociceptive Processing in Children and Adolescents: A Systematic Review

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Chemotherapy‐induced peripheral neuropathy remains a major complication in pediatric cancer, with disrupted somatosensory and nociceptive processing being a key aspect. This review synthesizes empirical studies on alterations in somatosensory and nociceptive processing in children and adolescents with cancer.
