This paper presents a distributed scheduling methodology for a two-machine flowshop problem. It is assumed that the decision authorities and information are distributed in multiple sub-production systems that must share two machines in order to satisfy their demands. The associated scheduling problems are modeled using 0/1 integer formulations, and the problem is solved using Lagrangian relaxat...

Remapping is an essential part of most Arbitrary Lagrangian-Eulerian (ALE) methods. In this paper, we focus on the part of the remapping algorithm that performs the interpolation of the fluid velocity field from the Lagrangian to the rezoned computational mesh in the context of a staggered discretization. Standard remapping algorithms generate a discrepancy between the remapped kinetic energy, ...

A sufficient condition is obtained for the development of a finite-time singularity in a highly symmetric Euler flow, first proposed by Kida @J. Phys. Soc. Jpn. 54, 2132 ~1995!# and recently simulated by Boratav and Pelz @Phys. Fluids 6, 2757 ~1994!#. It is shown that if the second-order spatial derivative of the pressure (pxx) is positive following a Lagrangian element ~on the x axis!, then a ...

Lagrangian analysis is becoming increasingly important to better understand the ocean's biological and biogeochemical cycles. Yet, biologists chemists often lack technical skills required set up such analyses. Here, we present a new product of pre-computed ocean Lagrangian trajectories (OLTraj) targeting non-expert users, demonstrate how use it by means worked examples. OLTraj based on s...

The paper concerns the formulation of a Lagrangian function compliant with classical, quantum and relativistic outcomes. literature Lagrangians are reported modified local Lorentz transformations, or potentials inferred directly from metric geometrical meaning. In this is formulated via concept uncertainty only, which allows non-deterministic approach. This theoretical frame proven useful to me...

Suppressing the effects of liquid loading is a key issue for efficient utilization of mid and late-life wells in shale-gas systems. This state of the wells can be prevented by performing short shut-ins when the gas rate falls below the minimum rate needed to avoid liquid loading. In this paper, we present a Lagrangian relaxation based scheme for shut-in scheduling of distributed shale multiwell...
