Sensitivity of cost coefficient errors in aggregate production planning

The cost implications of cost parameter estimation errors for an aggregate production planning problem are investigated. Three popular aggregate planning models (the Linear Decision Rule, the Linear Programming model, and the Production Switching ...

A stochastic model for multi-site aggregate production planning problems

, 2003
This paper addresses the problem of aggregate production planning (APP) for a multinational lingerie company in Hong Kong. The multi-site production planning problem considers the production loading plans among manufacturing factories subject to certain ...

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

Advanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

A hierarchical approach to multi-project planning under uncertainty. [PDF]

We survey several viewpoints on the management of the planning complexity of multi-project organisations under uncertainty. A positioning framework is proposed to distinguish between different types of project-driven organisations, which is meant to aid ...

A decision aid for Aggregate Production Planning (APP) strategies

Soaring complexity in markets and fast changes of products, technologies and supply chains as well as increasing uncertainty make it nearly impossible to fully integrate all relevant factors and information into decision-making processes in manufacturing.

Comparative Analysis Of Aggregate Production Planning Strategies (Pure Level, Chase, and Mixed) In The Gum Rosin And Turpentine Industry

Jurnal Civil Engineering Study
This study analyzes and compares three aggregate production planning (APP) strategies—Pure Level, Chase, and Mixed Strategy—in a gum rosin and turpentine industry characterized by seasonal raw material availability and fluctuating demand.

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.
