the dynamic nature of projects and the fact that they are carried out in changing environments, justify the need for their periodic monitoring and control. collection of information about the performance of projects at control points costs money. the corrective actions that may need to be taken to bring the project in line with the plan also costs money. on the other hand, penalties are usually...

abstract icssdom is a mathematical synthetic model that was written with fortran77 and in which used sa simulation annealing algorithm like an internal loop in basic structure of icss hydrodynamic simulation model. this model presented by mohseni movahed in 1381. this model is able assess current performance and present optimal operation considering downstream requirement of turnout in real con...

Bolstered by significant productivity improvement in manufacturing technology, the construction paradigm has shifted toward industrialized construction methods, such as modular construction. Modular construction has benefitted from the long term development of the manufacturing technologies and core techniques used in the assembly production lines of construction prefabrication plants. Lean pro...

The Department of Defense (DoD) Environmental Security Technology Certification Program and the Environmental Protection Agency sponsored a project to evaluate the benefits and utility of contaminant transport simulation-optimization algorithms against traditional (trial and error) modeling approaches. Three pump-and-treat facilities operated by the DoD were selected for inclusion in the projec...

asimulation-optimization approach is proposed for replenishment planning andshelf space allocation. the customers’ demand is divided into fixed andvariable demand. each customer follows a given path while shopping in thestore. by dividing the store space into several zones and calculating therelated substantial and random utilities, an analytical equation is proposedfor the probability of zone ...

Many real world manufacturing problems are too complex to be modeled analytically. The complexity of enterprise systems, the increasing needs for advanced collaboration between various systems within one institution or among many collaborating parties, and the velocity of organizational, policy, structural and market changes present nowadays challenges for the research community to develop more...

The healthcare system is no stranger to resource challenges in the face of unlimited demand fulfill objectives satisfying patients, maintaining service quality, and maximizing profit. Healthcare decision-makers are responsible for devising effective methods allocating scarce resources fairly a way that maximizes benefits at societal level. An emergency medical services (EMS) plays crucial role ...
