چکیده

Some extensions of a modeling system are described that facilitate higher level structure identification within a model. These structures, which often involve complementarity relationships, can be exploited by modern large scale mathematical programming algorithms. A specific implementation of an extended mathematical programming tool is outlined that communicates structure in a computationally beneficial manner from the GAMS modeling system to an appropriate solver.

Bi-objective optimization of multi-server intermodal hub-location-allocation problem in congested systems: modeling and solution

A new multi-objective intermodal hub-location-allocation problem is modeled in this paper in which both the origin and the destination hub facilities are modeled as an M/M/m queuing system. The problem is being formulated as a constrained bi-objective optimization model to minimize the total costs as well as minimizing the total system time. A small-size problem is solved on the GAMS software t...

Application of Genetic Programming to Modeling and Prediction of Activity Coefficient Ratio of Electrolytes in Aqueous Electrolyte Solution Containing Amino Acids

Genetic programming (GP) is one of the computer algorithms in the family of evolutionary-computational methods, which have been shown to provide reliable solutions to complex optimization problems. The genetic programming under discussion in this work relies on tree-like building blocks, and thus supports process modeling with varying structure. In this paper the systems containing amino ac...

A Multi-Formalism Modeling Framework: Formal Definitions, Model Composition and Solution Strategies

In this paper, we present a multi-formalism modeling framework (abbreviated by MFMF) for modeling and simulation. The proposed framework is defined based on the concepts of meta-models and uses object-orientation to overcome the complexities and to enhance the extensibility. The framework can be used as a basis for modeling by various formalisms and to support model composition in a unified man...
