Testing Process Predictions of Models of Risky Choice: A Quantitative Model Comparison Approach

open access: yesFrontiers in Psychology, 2013
This article presents a quantitative model comparison contrasting the process predictions of two prominent views on risky choice. One view assumes a trade-off between probabilities and outcomes (or nonlinear functions thereof) and the separate evaluation

A Multi-PR Heuristic for Distributed Multi-Project Scheduling With Uncertain Duration

open access: yesIEEE Access, 2020
Multiple projects are often managed and run in a decentralized setting. In this paper, considering the uncertainty in project implementation, we study the distributed multi-project scheduling problem with uncertain duration.

Operating Room Scheduling Considering Patient Priorities and Operating Room Preferences: A Case Study [PDF]

open access: yesInternational Journal of Industrial Engineering and Production Research, 2022
Operating rooms have become the most important areas in hospitals because of the scarcity and cost of resources. The present study investigates operating room scheduling and rescheduling considering the priority of surgical patients in a specialized ...

An improved performance of greedy heuristic solutions for a bi-criteria mixture packaging problem of two types of items with bounded weights

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2020
In this paper, we treat a lexicographic bi-criteria combinatorial optimization model of mixture packaging of two types of items, which arises in actual food packing systems, so-called multi-head weighers.

Solving the Fixed Charge Transportation Problem by New Heuristic Approach [PDF]

open access: yesJournal of Optimization in Industrial Engineering, 2019
The fixed charge transportation problem (FCTP) is a deployment of the classical transportation problem in which a fixed cost is incurred, independent of the amount transported, along with a variable cost that is proportional to the amount shipped.

A Novel Priority Rule Heuristic: Learning from Justification

open access: yesProceedings of the International Conference on Automated Planning and Scheduling, 2014
The Resource Constrained Project Scheduling Problem consists of finding start times for precedence-constrained activities which compete over renewable resources, with the goal to produce the shortest schedule. The method of Justification is a very popular post-processing schedule optimization technique which, although it is not clear ...

Heuristic Optimization of Rough-Mill Yield With Production Priorities [PDF]

open access: yesJournal of Engineering for Industry, 1991
Efficient lumber utilization at the saw has become a key issue in the woodworking industry. This is because of shrinking supply and increasing raw materials prices. In this paper, formulation of the cross-cut first method of cutting defects out of lumber as a one-dimensional stock cutting problem is discussed.

Synergistic Compatibilization of CsPbBr3 Perovskites and HfO2 Nanocrystals for Hybrid Sensitized Nanoscintillators

open access: yesAdvanced Functional Materials, EarlyView.
Lead halide perovskite nanocrystals are promising scintillators but suffer from reabsorption losses and limited compatibility with high‐Z additives. Hybridization of CsPbBr3 nanocrystals with PbBr2‐passivated HfO2 nanoparticle sensitizers, achieved during or after synthesis, produces stable composites with maintained optical quality, improved ...
