Abstract Multistores are data management systems that enable query processing across different and heterogeneous databases; besides the distribution of data, complexity factors like schema heterogeneity replication must be resolved through integration fusion activities. Our multistore solution relies on a dataspace to provide user with an integrated view available enables formulation execution ...

We propose a two-stage recoverable robustness approach that minimizes the recovery cost. In many applications, once uncertainty ξ $$ \xi is revealed, it can be more important to recover solution x {x}^{\xi } which as similar possible nominal n o m {x}^{nom} than minimize objective value of . This for example occurs when implemented on regular basis or revealed late. define proactive problem wei...

improving mechanical properties of composites based on strength-to-weight ratio has been gained much attention in various applications. having the most resistant and at the same time the lightest and the most economical structure is believed as an aim in these applications. these three factors are usually opposed to each other. so, applying optimization algorithms for improving mechanical prope...

in this paper, a combinational optimization algorithm is introduced to obtain the best size and location of static compensator (statcom) in power systems. its main contribution is considering contingency analysis where lines outages may lead to infeasible solutions especially at peak loads and it commonly can be vanished by load-shedding. the objective of the proposed algorithm is firstly to pr...

The synthesis of heat integrated multi-component distillation systems is complex due to its huge search space for structural combination and optimization computation. To provide a systematic approach and tools for the synthesis design of distillation systems, a new method for modeling heat integrated columns is presented, and the operating cost objective function is minimized by improved harmon...
