Archived Theses and Dissertations
Construction industry around the world is facing a huge revolution in terms of number of executed projects. Projects are no longer simple ones managed by few persons. Commercial buildings, high rise towers and bridges are being built everywhere. The majority of these projects are complex ones that face a lot of obstacles. Delays are one of the major obstacles that construction projects face and are very likely to occur. Generally, claims are the result of any delay in the construction progress. To be able to analyze the claim and assign the responsibility, the analyst has to perform a delay analysis. …

The problem addressed in this research is the scheduling of an agile manufacturing system comprised of machining and assembly operations with the objective of minimizing the makespan. This problem has been addressed in the literature using heuristics and metaheuristics. In addition, a lower bound has been developed. This research builds upon the findings of the recent literature and proposes two enhanced algorithms, parallel simulated annealing and parallel modified simulated annealing, to solve the addressed problem. The performance of the developed algorithms is compared to that of another simulated annealing algorithm that is available in the literature. Performance comparisons are based …
