this study aims to deal with a more realistic combined problem of project scheduling and material ordering. the goal is to minimize the total material holding and ordering costs by determining the starting time of activities along with material ordering schedules subject to some constraints. the problem is first mathematically modelled. then a hybrid simulated annealing and genetic algorithm is...

urban design has been used in the cities throughout the world to achieve certain goals and purposes. it has been common in developing countries, including iran, to use urban regeneration plans in the older sections of large cities to eliminate urban blight and decay, and eventually achieve modernization and in some cases to also overcome socio-economic and cultural problems. approaches have bee...

Design/bid/build and design/build are two principal project delivery systems used worldwide. The performance of each project may differ with the type of procurement system used. This study has two aims: firstly, to assess and compare the performance of design/bid/build and design/build projects in Lebanon; secondly, to compare the results with the performance of equivalent systems in the Far Ea...

System engineering is one of the most powerful tools for comprehensive project management and control. This tool emphasized the life cycle of the projects, manages every single activity and helps manage the main elements of the project through a set of management and engineering processes. The goal of the current study is to use a system engineering approach in design phase in order or to meet ...
