FLOPC++ is an open source algebraic modeling language implemented as a C++ class library. It allows linear optimization problems to be modeled in a declarative style, similar to algebraic modeling languages, such as GAMS and AMPL, within a C++ program. The project is part of COmputational INfrastructure for Operations Research (COIN-OR) and uses its Open Solver Interface (OSI) to achieve solver...

Abstract The performance of factorial designs is still limited due to some uncertainties that usually intensify process complexities, hence, the need for inter-platform auto-correlation analyses. In this study, capabilities and General Algebraic Modeling System (GAMS) on effects pertinent operating variables in wastewater treatment were compared. Individual combined models implemented GAMS solv...

Abstract A coupled model system, consisting of a distributed hydrological model and an economic optimization model, is applied 1) to investigate regional interdependencies between irrigated agriculture and regional water balance and 2) to identify optimized cultivation strategies. The coupled model system is applied to a case study for the semi-arid Atankwidi catchment in West Africa. The hydro...

This paper presents a new approach for finding capacitor's location and it's sizing in radial distribution system (RDS) optimally with an aim of reducing the active power loss. In this paper, problem minimizing loss is converted into Mixed Integer Non-Linear Program (MINLP) problem, it will be solved by using Generalized Algebraic Modeling Systems (GAMS) software MINLP-SBB Solver. The proposing...

Environmental concerns and depletion of nonrenewable resources has made great interest towards renewable energy resources. Cleanness and high potential are factors that caused fast growth of wind energy. However, the stochastic nature of wind energy makes the presence of energy storage systems (ESS) in wind integrated power systems, inevitable. Due to capability of being used in large-scale sys...

Excessive buffer inventory may disrupt production and constitute one of the main problems. One ways coping with problems in mass lines is to achieve implement a detailed schedule. In this study, company line white goods sector consideration. A mixed-integer programming model sequence-dependent setup times has been developed solve excessive work process for dye house station company. The applied...

The paper discusses the role of Graphical User Interfaces in economic modelling and specifically the development of a new Graphical User Interface Generator for applications realized in GAMS (General Algebraic Modelling System), a widely used Algebraic Modelling Language for (bio-)economic simulation models. It motivates the development of GGIG (Gams Graphical Interface Generator) by reviewing ...

Most of the applied models written with an algebraic modeling language involve simultaneously several dimensions such as materials, location, time or uncertainty. The information about dimensions available in the algebraic formulation is usually su cient to retrieve di erent block structures from mathematical programs. These structured problems can then be solved by adequate solution techniques...
