The aim of this work is to design and optimize a 2D Arch Bridge with reliability based optimization concept that is commonly used in transportation. After the arch bridge is modeled according to its original layout, the formulation of reliability-based optimization and other optimization techniques used in the work are presented. Then the bridge is optimized using various optimization methods u...

Proper cost estimation is one of the vital tasks that must be achieved for software project development. Owing to complexity and uncertainties development process, this task ambiguous difficult. Recently, analogy-based (ABE) has become popular approaches in field due its effectiveness practicability comparing completed projects new estimating effort. However, spite many achievements, method not...

Using the additive weight method of vector optimization problems and the method of essential solutions, we study some continuity properties of the mapping which associates the set of efficient solutions S(f ) to the objective function f . To understand such properties, the key point is to consider the stability of additive weight solutions and the relationship between efficient solutions and ad...
