MANAGING THE ECONOMIC REPLACEMENT OF AN OPERATIONAL VEHICLES: A HEURISTIC DECISION MODEL [PDF]

open access: yesICTACT Journal on Management Studies, 2016
A heuristic decision model for the replacement of an operational vehicle was developed. The proposed model is based on analysingan economic measures incorporating the most important factors such as: operation and maintenance costs, salvage values ...

How to study cognitive decision algorithms: The case of the priority heuristic

open access: yesJudgment and Decision Making, 2010
Although the priority heuristic (PH) is conceived as a cognitive-process model, some of its critical process assumptions remain to be tested. The PH makes very strong ordinal and quantitative assumptions about the strictly sequential, non-compensatory ...

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.

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

open access: yesFEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

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.

A linear programming-based method for job shop scheduling [PDF]

open access: yes, 2012
We present a decomposition heuristic for a large class of job shop scheduling problems. This heuristic utilizes information from the linear programming formulation of the associated optimal timing problem to solve subproblems, can be used for any ...

Clinician and Patient Factors Associated With Long‐Term Glucocorticoid Use in People With Rheumatoid Arthritis Receiving Advanced Therapies

open access: yesArthritis Care &Research, EarlyView.
Objective Despite guideline recommendations, long‐term glucocorticoid (GC) use is common in rheumatoid arthritis (RA). We conducted a clinician survey nested within a large registry to identify patient and clinician factors associated with GC use. Methods Clinicians contributing patients to the CorEvitas Rheumatoid Arthritis Registry were surveyed ...
