Scheduling flexible flow shops with sequence-dependent setup effect [PDF]

Proceedings of 35th IEEE Conference on Decision and Control, 2002
This paper presents an optimization model-based approach for production scheduling of flexible flow shops where sequence-dependent setup effect is significant. The scheduling problem is formulated as an integer programming problem. In the presence of setup effect, individual machine setup status must be scheduled in accordance with part processing ...

ALDOA Promotes Glycolysis and NLRP3/GSDMD Pyroptosis to Accelerate ALS Progression

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Amyotrophic lateral sclerosis (ALS) is characterized by progressive motor neuron degeneration. Glycolytic dysregulation is implicated in disease progression, yet the underlying mechanisms remain unclear. This study investigates how Aldolase A (ALDOA) drives ALS progression through glycolysis‐mediated motor neuron pyroptosis.

Incorporating Worker Heterogeneity in Flexible Flow Shop Environment

The Eurasia Proceedings of Science Technology Engineering and Mathematics
We study the flexible flow shop scheduling problem with the heterogeneous worker assignment. Inmany real-life manufacturing systems with flow shop environments, one of the fundamental schedulingchallenges that needs to be addressed is job sequences across multiple workers.

Effectiveness of rTMS on Working Memory and Inhibitory Impairments in Patients With Post‐Stroke Executive Deficits

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Considerable efforts have been dedicated to developing effective treatments for post‐stroke executive impairment (PSEI), among which repetitive transcranial magnetic stimulation (rTMS) has shown great potential. This study aimed to investigate the therapeutic effects of high‐frequency rTMS on working memory (WM) and response ...

INSERTION HEURISTIC FOR THE SINGLE ROW LAYOUT PROBLEM IN FLEXIBLE MANUFACTURING SYSTEMS [PDF]

, 2013
An important problem in a Flexible Manufacturing System (FMS) is to obtain a layout of machines such that material handling is the most efficient. Since poor layout would result in more parts spending longer time moving from one machine to another ...
