In this paper, a methodology is presented for optimum shape design of double-layer grids subject to gravity and earthquake loadings. The design variables are the number of divisions in two directions, the height between two layers and the cross-sectional areas of the structural elements. The objective function is the weight of the structure and the design constraints are some limitations on str...

in this paper, thermal effect of plasma arc welding is investigated, and temperature field of ferrite stainless steel is acquired. thermal effect of plasma arc and subsequently the generated temperature field in the work piece is the key for analysis and optimization of this welding process, which is the main goal of this paper. finite element simulation of welding process by simplec method and...

Interorganizational business process reengineering is a logical extension of discussions in the 1980s of the potential for interorganizational systems to fundamentally redefine relationships between buyers and sellers and even competitors within an industry context. This paper presents a framework or model describing the relationship between technological and process innovations, and describes ...

Technological equipment design based on functionally modular methods is widely used in various technical fields. The designed object can be a technological machine, production line, or manufacturing complex. Special attention paid to the optimization of its structure. sequence performing all stages synthesis problem presented article. To find solution this task, developer should apply complete ...

Optimization of turning process is a non-linear optimization with constrains and it is difficult for the conventional optimization algorithms to solve this problem. The purpose of present study is to demonstrate the potential of Imperialist Competitive Algorithm (ICA) for optimization of multipass turning process. This algorithm is inspired by competition mechanism among imperialists and coloni...

The present paper tackles the optimization problem of double layer grids considering nonlinear behaviour. In this paper, an efficient optimization algorithm is proposed to achieve the optimization task based on the newly developed grey wolf algorithm (GWA) termed as sequential GWA (SGWA). In the framework of SGWA, a sequence of optimization processe...

Abstract: This paper is about Iranian health industry facing the challenges created by the comprehensive international sanctions. This paper aims to give a realistic account of the different positive and negative impacts of the factor of international collaboration (or rather, the lack thereof) on the dual aspects of "technological and non-technological" catching up process. The case study is r...
