This paper presents a hydrodynamic model of Mobile Bay developed using the Adaptive Hydraulic Modeling system (ADH), the Hydrological Simulation Program FORTRAN (HSPF), and the Mesh Generation and Refinement Tool (MGRT), to simulate water surface elevations in Mobile Bay, Alabama. The computational grid was created using MGRT and NOAA’s coastline and bathymetric data. HSPF provided stream flow ...

Recent extensive water quality surveys in Ireland revealed that diffuse phosphorus (P) pollution originating from agricultural land and transported by runoff and subsurface flows is the primary cause of the deterioration of surface water quality. P transport from land to water can be described by mathematical models that vary in modelling approach, complexity and scale (plot, field and catchmen...

در این مقاله یک مدل ریاضی برای مسئله سیستم تولیدی همکارانه ساخت بر اساس سفارش با رعایت انصاف تخصیص بار‌های تولید طراحی شده است. اهداف اصلی مدل، کمینه‌سازی هزینه‌‌های کل و حداکثر استفاده از منابع به‌منظور عادلانه شرایط عدم­قطعیت کنترل پارامتر‌های غیرقطعی روش برنامه‌ریزی فازی ‌شده نتایج نشان می‌دهد افزایش نرخ عدم‌قطعیت، می­یابد. ازآنجاکه ظرفیت کارخانه‌ها ثابت است، مقدار تقاضا، هر کارخانه نیز می­ی...

INTRODUCTION: EDYS (Ecological DYnamics Simulation Model) is a general ecosystem simulation model that is mechanistically based and spatially explicit (Childress and McLendon 1999; Childress et al. 1999, 2002). The model simulates natural and anthropogenic-induced changes in plant, soil, animal, and watershed components across landscapes, at spatial scales ranging from 1 m or less to landscape ...
