A heuristic approach for path planning for redundant robots
… Several fuzzy logic controllers combined with heuristic algorithms are used to avoid the obstacles in the workspace and to avoid self collision of the links.

A Heuristic Approach to Solve Air Taxi Scheduling Problem
All passengers travel at the hour most convenient to them. But it is not always possible to find a flight at the right time to fly them to their destination. In the case where service in any one time period is insufficient to meet air travel demanded, it may be expected that some unfilled demand …

A Heuristic Approach To Designing A Unique Ships Grid With Energy Storage for the Future Fleet of River Tender Ships
… Maritime Community and the USCG. An applicable Heuristic Design Methodology is provided in conjunction with the Unique Ships Grid. This Design Methodology can be used with a simple load analysis and results in a Load Center breakdown and the sizing of Cables, Generators, Inverter, and required …

Models and algorithms for dynamic real-time freight train re-routing
… the evaluation framework: an optimization-based approach and a search-based heuristic approach. A further problem variant is also introduced where rail terminal processing rate is a non-constant function of the traffic at the rail terminal. The above approaches are extended to address the problem …

Optimal portfolio choice : beyond the traditional expected utility maximization paradigm
… thesis focuses on two major portfolio selection approaches: the traditional mean-variance approach and the heuristic approach based on risk budgeting. The main results from mean-variance are reviewed, as well as some novel results, followed by new contributions in the area of calculating expected …

A pattern enumeration approach to the trim loss problem
… only had a limited range of applicability. A heuristic approach is proposed, based on pattern enumeration, which can be used to develop scheduling methods for a reasonably wide class of trim loss problems. The effectiveness of the approach depends on its ability to avoid the intractable …

Tabu search for bus and train driver scheduling with time windows
… on the duty generation. The generate-and-select approach is at present the most successful for bus and train driver scheduling. It involves generating a set of legal potential driver duties from which a minimal and most efficient subset is selected. Filtering rules are often applied so that the …

Managing Disturbances in Supply Chain Systems
… a real-time basis. In this thesis, the developed approach was divided into several steps. At first, a plan was developed without considering any disturbance. Then a mathematical model was formulated to obtain a revised plan after the occurrence of a disturbance in the system. An efficient …

Reflections of Teenage Mothers Who Chose Unprotected Sex At the Time of Conception
… time their babies were conceived. A qualitative, heuristic approach was utilized in which teens were allowed to discuss in their own words the sentiments, opinions, and ideologies that impacted their sexual decision-making. A convenience sample of 8 subjects was recruited from a local facility …

Balancing of Parallel U-Shaped Assembly Lines with Crossover Points
… problem solutions based on the proposed heuristic approach with the traditional approach highlights the possible reduction in the quantity of workers required. The conclusion from this research is that a wider variety of products can be manufactured at the same capital expense using …

The design of adaptive structures for wing morphing
… using efficient structural shape optimisation. A heuristic approach is proposed in this work that enables morphing through a range of stable cambered airfoils to achieve aerodynamic properties for different manoeuvres, with the benefit of low powered actuation control. This allows large changes in …

Lattice modeling of ultrasonic nondestructive evaluation of attenuating materials
… must include attenuation. Lattice modeling is a heuristic approach that consists of the discretization of solids into regularly spaced particles interconnected via nearest-neighbor interactions. For example, the mass-spring-lattice model (MSLM), a lattice model for the simulation and …

Inventory optimization in a retail multi-echelon environment
… order-up-to-levels are set as constraints. A heuristic approach, that combines the optimization and simulation methods, is used to find the optimal inventory distribution. The results show that the optimal network carrying cost can be achieved by having low inventory and low service level at …

Using Machine Learning to Predict Sag and Leveling Behavior of Interior Architectural Paints
… mathematical derivation; however, neither approach adequately predicts sag and leveling behavior. This provides the opportunity for machine learning to create a powerful model that utilizes formulation and rheological data and industry-standard tests to predict sag and leveling before the …

Combination of a Probabilistic-Based and a Rule-Based Approach for Genealogical Record Linkage
… entity. Currently, there exist many different approaches for record linkage. Some approaches incorporate the use of heuristic rules, mathematical models, Markov models, or machine learning. This thesis focuses on the application of record linkage to genealogical records within family trees. …

Variable neighbourhood search based heuristic for K-harmonic means clustering
… at their present speed. In such cases, the heuristic approach can be used. Heuristic research has been used by many researchers to supply this need. It gives a sufficient solution in reasonable time. The clustering problem is one example of this, formed in many applications. In this thesis, …
