ABSTRACT: Feasible solutions of Bilevel programming (BLP) problem have to satisfy the optimality conditions of a lower level optimization problem which is defined as part of its constraints. Multiobjective BLP (MOBLP) problems are the special case of BLP problems with multiple objectives at the upper level which require every feasible solution to satisfy the Pareto optimality conditions of a lo...

The aim of this paper is to present a non formulation of a daily dairy cow ration. The basis of its construction lies in the models developed by earlier researchers on the Excel Solver platform. It merg goal programming model with linear objective of minimizing the deviations. The single objective linear model helps in making an estimation of least-cost magnitude that might be expected. The pro...

Geometric programming is a mathematical technique, which has been developed for nonlinear optimization problems. This technique is based on the dual program with linear constraints. Determination of species concentrations in chemical equilibrium conditions is one of its applications in chemistry and chemical engineering fields. In this paper, the principles of geometric programming and its comp...

a theorem was recently introduced to establish a relationship betweengoal programming and fuzzy programming for vectormaximum problems.in this short note it is shown that the relationship does not exist underall circumstances. the necessary correction is proposed.

This paper presents a fuzzy goal programming (GP) procedure for solving a multiobjective linear plus linear fractional programming problem. In the proposed approach GP model for achievement of the highest membership value of each of fuzzy goal defined for the linear plus linear fractional objectives is formulated. In the solution process, the method of variable change on the underand overdeviat...

Due to its ability to handle resources in a nely controlled way, linear logic is being adopted as a foundation of several logic programming and speciication languages in which some notions of state can be modelled. In particular, some of these were proposed with the main motivation of allowing the speciication of concurrent systems: such systems incorporate small subsets of linear logic or have...

  A fuzzy goal programming-based approach is used to solve a proposed multi-objective linear programming model and simultaneously handle two important problems in cellular manufacturing systems, viz. cell formation and layout design. Considerations of intra-cell layout, the intra-cell material handling can be calculated exactly. The advantages of the proposed model are considering machining cos...

This paper presents the results of research undertaken to assess the suitabtlity of multiple cnteria dec1s1on techniques to agricultural planning problems. The conventional mathematical programmmg paradigm as used in the form of linear programming is inadequate to deal with real agncultural planning problems when multiple goals and objectives are important elements of the situation. Goal progra...

Environmental concerns prompt the world for a transition to renewable energy sources from fossil energy. Reducing dependency on non-renewable of is prerequisite sustainable and less environmental pollution. Biogas energy, which one most important sources, produced by burning organic wastes can be used in many different fields. In this study, two-stage approach undertaken optimize biogas supply ...
