World wide crude transportation is the central logistics operation that links the upstream and downstream functions and plays a crucial role in the global supply chain management in the oil industry. In this work, we develop a decision support system to investigate and improve the combined inventory and transportation system in a representative world-wide crude supply problem. The decision supp...

In the five decades of modern project management (the computer age), PM software developers have made constant strides in providing support within their tools for the continuing challenge of assigning resources to projects and tasks. Many of these solutions have failed to garner the support of the tools users. Some products have totally flopped and have quickly been removed from the market. Oth...

A discrete event simulation based “on-line near-real-time” dynamic scheduling and optimization system has been conceptualized, designed, and developed to optimize cycle time and asset utilization in the complex manufacturing environment of semiconductor test manufacturing. Our approach includes the application of rules and optimization algorithm, using multiple variables as an integral part of ...

The paper presents a methodology for incremental development of large discrete-event simulation models. The proposed methodology has evolved during a project performed in collaboration with BT Products. The methodology is based on configuration management to secure simulation model integrity and modularization of the model. Modularization reduces complexity, allows modeling at a higher level of...

The efficacy of managing a construction project mainly depends on proper planning and scheduling. Mass housing projects are highly repetitive in nature, as the methods used for construction are often repetitive or cyclic. Resources are therefore being deployed repeatedly for the similar or identical tasks in these projects. In order to eradicate delays in mobilizing resources, an efficient reso...

Owners, managers and operators of most businesses are now increasingly aware of their responsibility to the environment. Oftentimes, however, there are significant costs associated with environmental initiatives. Fortunately though, adopting sensible, effective and efficient energy, water and waste management practices may result in substantial savings. In this paper, we report on the developme...
