Optimizing resource allocation in a portfolio of projects related to technology infusion using heuristic and meta-heuristic methods
… rework, is included into the model. Therefore, methods for effectively allocating resources in a portfolio of projects related to technology infusion are recommended. Initially, a heuristic method is proposed based on priority rules. However, as the assumptions of the model are loosened a novel …

A multi-attribute layout design problem
… functions and then solving the problem by heuristic methods. Exact methods guarantee optimal solution but are computationally intensive for large sized problems. Heuristic methods do not guarantee optimal solution, but are computationally less intensive and relatively faster than the exact …

A Combined Inventory-Location Model for Distribution Network Design
… problems together and investigates different heuristic methods for solving a combined inventory-location model. We begin by presenting the background and formulation for each problem. These formulations are then combined to show how the two problems can be mathematically formulated together. …

Two Combinatorial Optimization Problems at the Interface of Computer Science and Operations Research
… To solve this problem, exact algorithms and heuristic methods are presented. Different multi-objective problems with various numbers of objectives and constraints are used to compare the performances of the proposed algorithms and heuristics.

THE INVENTORY ROUTING PROBLEM WITH THIRD PARTY LOGISTICS
… characteristics simultaneously. In this research heuristic methods are developed to solve large problems for which optimization packages cannot find even a feasible solution. Two heuristic methods are proposed for this problem, which are based on fix-and-run algorithm. Three improvement phases are …

Optimizing select-project-join queries
… of retrieval algorithms. This thesis explores heuristic methods for optimizing relational database query algorithms. It combines individual works on heuristics, cost modeling, decomposition, and join optimization. Lastly it assesses these optimization methods.

A decision support method for selecting design and manufacturing alternatives
… by using AHP alone, can be aggregated by two heuristic methods based on distance function, to generate an index for final single selection. The first method uses the final weights obtained by AHP, while the second method uses its detailed weights. AHP weights are then used to construct the …

Modeling, Analysis, and Algorithms for Some Supply Chain Logistics Optimization Problems
… develop an optimum-seeking algorithm and a fast heuristic, both of which exploit structural properties of the problem. The second problem is a joint production and delivery scheduling problem in which a single vendor supplies goods to a single buyer over a finite horizon. We model this …

Towards heuristic systems methods for generating new knowledge in post-industrial business
… aspects of post-modern philosophy into systems methods that support new knowledge creation in post-industrial business. The author has developed a three-part model of the organization as a knowledge system: The first component is the formative system, which enables or regulates what can be …

A novel approach for route generation and real-time scheduling for public services
… and real-time events, this study proposes two heuristic methods: Smart Selective Navigator and a two-stage algorithm for real-time scheduling and route generation. Through two major case studies — winter operations in the City of Oshawa and autonomous street sweeping in Uchi Park —the proposed …

Long-term scheduling in underground coal mining using mixed binary programming
… (primal) problem, solved by a combination of heuristic and exact methods, and the subproblem (dual problem), solved partly by inspection and partly as a minimal cost network flow problem. The heuristic methods are based on improvements of existing algorithms for scheduling precedence-related …

Mapping numerical software onto distributed memory parallel systems
… of parallelising compilers rely heavily on heuristic guidance in parallel code generation and other decisions that may be better made by a human. As a result, the code they produce will almost certainly be inferior to manually produced code. Also, in order not to sacrifice parallel code …

Pattern Recognition of Power Systems Voltage Stability Using Real Time Simulations
… cases of voltage collapse, we shall create methods using pattern recognition in conjunction with real time simulation of case studies and shall develop heuristic methods for separating voltage stable cases from voltage unstable cases that result in response to system contingencies and …

Air force crew allocation and scheduling problem
… Base. This thesis reports on experience with two heuristic methods developed, each applicable to the different variants of the problem. Although the problem described herein is peculiar to this situation, the heuristic scheduling and dispatching rules developed have been found to be very …

Techniques for mathematical analysis and optimization of agent-based models
… discrete difference equations, and a variety of heuristic methods. The proposed strategies are novel in their application; results show that for a large class of models, these strategies are more effective than existing methods.

The application of simulated annealing to the mixed model, deterministic assembly line balancing problem
… techniques are limited to small problems. Heuristic methods, on the other hand, are often too simplistic to find good solutions. Furthermore, many of the existing techniques cannot be expanded to handle the mixed model problem. Simulated Annealing (SA) is a search methodology which has …
