tower cranes are major and expensive equipment that are extensively used at building construction projects and harbors for lifting heavy objects to demand points. the tower crane locating problem to position a tower crane and supply points in a building construction site for supplying all requests in minimum time, has been raised from more than twenty years ago. this problem has already been so...

In mining projects, all uncertainties associated with a project must be considered to determine the feasibility study. Grade uncertainty is one of the major components of technical uncertainty that affects the variability of the project. Geostatistical simulation, as a reliable approach, is the most widely used method to quantify risk analysis to overcome the drawbacks of the estimation methods...

As an important component of road transportation, the bus terminal has always been focus research. Therefore, this article uses a combination quantitative and qualitative analysis to study Zhengding third-level from perspective layout analysis. On basis actual investigation, relevant indicators scale are calculated. At same time, three functional areas process flow lines inside passenger statio...

Abstract A new interactive truss layout optimization web-app has been developed for educational use. This designed to be used on a range of devices, from mobile phones desktop PCs. Truss designs are first generated via numerical and then rationalized geometry optimization. It is shown that these can simplified using computationally inexpensive process allows the user control trade-off between c...

Structural optimization, when approached by conventional (gradient based) minimization algorithms presents several difficulties, mainly related to computational aspects for the huge number of nonlinear analyses required, that regard both Objective Functions (OFs) and Constraints. Moreover, from the early '80s to today's, Evolutionary Algorithms have been successfully developed and applied as a ...
