classical deterministic inventory models consider the demand rate to be either constant or time-dependent but independent from the stock status. however, for a certain type of inventory, the demand rate may be in-fluenced by the stock level. also in many real-life problems, some products such as fruits, vegetables, phar-maceuticals and volatile liquids continuously deteriorate to evaporation, o...

dam reservoirs supply potable, agricultural, and industrial water in most cities of iran. due to lack of proper operational rules or unbalanced demand versus water resources volume, (along operating time) correction in operational rules is required to fulfill current situations. hence the goal of this study is to optimize the qeshlaq dam reservoir operation rules to maximize the water release f...

The vision of the research project is to find an energy optimal building configuration, suitable for specified requirements and restrictions. first step on this way create a measure compare configurations, faster than explicit energetic simulations. current study examines applicability multivariate linear regression support solution optimization problems. During study, models were created estim...

the aim of the present paper is to evaluate the influence of the soil- foundation- structure interaction (sfsi) effects on the component demand modifier factor of concrete gravity beams based on asce 41-06 standard. to this end, the beam on the nonlinear winkler foundation approach is employed which is a simple and efficient method. at first, four sets of 3-, 6-, 10- and 15-storey concrete mome...
