CFD Analysis of Wheel Hub Paddle Hub and Roll Cage in Solid Works
No full textThe aerodynamics plays an important role in the design process of the automotive. So CFD computational fluid dynamics is the fluid mechanics branch that uses algorithms and numerical analysis to analyze problems of fluid flow that is to investigate the fluid flow. It is basically originated from the Naviers Strokes equation. In this we work on solid works software to analyse the CFD on the design of roll cage of a vehicle named effi cycle. This reviews the analysis on the various members of roll cage. Here the analysis of wheel hub, paddle hub, and the roll cage on the solid works software.

A COST AND PIPELINE TRADE-OFF IN A TRANSPORTATION PROBLEM
Get PDFAbstract: The present paper deals with a trade off between cost and pipeline at a given time in a transportation problem. The time lag between commissioning a project and the time when the last consignment of goods reaches the project site is an important factor. This motivates the study of a bi-criteria transportation problem at a pivotal time T . An exhaustive set E of all independent cost-pipeline pairs (called efficient pairs) at time T is constructed in such a way that each pair corresponds to a basic feasible solution and in turn, gives an optimal transportation schedule. A convergent algorithm has been proposed to determine non-dominated cost pipeline pairs in a criteria space instead of scanning the decision space, where the number of such pairs is large as compared to those found in the criteria space. 197 198 Vikas Sharma, Rita Malhotra, Vanita Verma / A Cost And Pipelin
Some Ascpects of Bilevel Programming
No full textMS, SMCABilevel programming involves two optimization problems where the constraint region of the first level problem is implicitly determined by another optimization problem. It has been applied to decentralized planning problems involving a decision process with a hierarchical structure. In this thesis we have discussed three problems in the field of bilevel optimization. In the first problem a bilevel linear/linear fractional programming problem has been discussed, where the objective function for the first level is linear, objective function for second level problem is linear fractional and the common constrained region is polyhedral. It has been discussed that an optimal solution can be found which is an extreme point of the polyhedron. Moreover, by taking into account the relationship between feasible solutions to the problem and bases of the technological coefficient submatrix associated to variables of the second level, an enumerative algorithm is proposed that finds a global optimum to the problem.
Second problem discussed in the thesis, consist of a linear fractional objective function at both the levels. It has been discussed that an optimal solution to this problem occurs at a boundary feasible extreme point. A Kth best algorithm has been proposed to solve this problems, further it has also been discussed this algorithm can also be extended to quasiconcave bilevel problems, provided that the first level objective function is explicitly quasimonotone.
The last problem we have considered is a nonlinear bilevel programming problem, where the objective function of first level is a indefinite quadratic function and the lower level objective function is linear. By making use of duality theory, bilevel program is transformed into an equivalent single level programming problem, which can further be converted into a programming problem without constraints. By using genetic algorithm and optimal solution of this problem is obtained
