performance measure approach (pma) is a method for evaluating the probabilistic constraints in reliability-based design optimization of structures. the advanced mean-value (amv) method is suitable for pma, simply and efficiently. the iterative amv scheme could be yielded to unstable solutions such as periodic-oscillation and chaos for highly nonlinear performance functions. in the present paper...

Assembly lines are flow-oriented production systems that are of great importance in the industrial production of standard, high-volume products and even more recently, they have become commonplace in producing low-volume custom products. The main goal of designers of these lines is to increase the efficiency of the system and therefore, the assembly line balancing to achieve an optimal system i...

The problems of non-normality or functional relationships between variables may often be simplified by an appropriate transformation. However, the evidence for transformations may sometimes depend crucially on one or a few observations. Therefore, the purpose of the paper is to develop a method that will not be influenced by potential outliers during the process of data transformations. The con...

Problem definition: The theoretical investigation of the effectiveness limited flexibility has mainly focused on a performance metric that is based maximum sales in units. However, this could lead to substantial profit losses when used guide designs while products have considerably large margin differences. Academic/practical relevance: We address issue by introducing differentials into analysi...

Dealing with uncertain rail disruptions effectively raises a significant challenge for computational intelligence research. This article studies the bus bridging problem under demand uncertainty, where passenger is represented as parametric interval-valued fuzzy variables and their associated uncertainty distribution sets. A distributionally robust optimization model proposed to minimize maximu...

hub location-allocation problems are currently a subject of keen interest in the research community. however, when this issue is considered in practice, significant difficulties such as traffic, commodity transportation and telecommunication tend to be overlooked. in this paper, a novel robust mathematical model for a p-hub covering problem, which tackles the intrinsic uncertainty of some param...
