In ever increasing competition in the automotive sector, there is a growing need to reduce the vehicle development time and bring new vehicles to market much faster and first time right with the desired attributes in order to retain the competitive advantage. Powertrain systems engineering is an important area which affects many critical Vehicle attributes perceived by the customer. Most of these powertrain attributes often impose conflicting requirements on the Powertrain design parameters. These conflicts are most often realized at a very late stage of the vehicle development which results in rework and delays as currently there is no Process available to optimize the Powertrain attributes quite early in the program In this paper, few key Powertrain attributes are shortlisted to demonstrate the new approach for powertrain multi-attribute target development for vehicle integration. A design structure matrix (DSM) provides a simple, compact, and visual representation of a complex system that supports innovative solutions to decomposition and integration problems11. A Design Structure Matrix is created for the Powertrain attributes to demonstratevarious interactions among powertrain attributes and balance the Targets.
This Research paper aims to develop and demonstrate Powertrain attributes Design Structure Matrix as a new approach for powertrain multi-attribute target development and balancing for vehicle integration.

SmAlO3 perovskite material was prepared by solution combustion technique. The ac conductivity and dielectric properties of the sintered pellet of the sample have been investigated in the frequency range 1Hz to 1MHz and temperature range 303K-783K. The experimental results indicate that the ac conductivity (ω), dielectric constant ( ) and loss tangent ( ) depends on depends on the temperature and frequency. The ac conductivity was found to obey the power law ωn with and the behavior of exponent n with temperature suggested that the conduction mechanism in the ceramic follows OLPT model. The obtained results are compared to the principal theories that describe the universal dielectric response behavior. The value and tan were found to be temperature and frequency dependent.

In this paper, we have discussed the MHD flow of visco-elastic fluid through a loosely packed porous medium in an impulsively started vertical plate with variable heat and mass transfer. The temperature of plate is made to rise linearly with time. The fluid considered is gray, absorbing-emitting radiation but a non-scattering medium. The equations for the governing flow are solved by making use Laplace-transform technique. The velocity, temperature and concentration are obtained analytically and computationally discussed with reference to governing parameters and are illustrated graphically,
and physical aspects of the problem are discussed. Also skin friction, Nusselt number and Sherwood number are obtained
analytically and are tabulated.

In this paper, we have considered the heat transfer on the unsteady hydromagnetic convective flow of an incompressible viscous electrically conducting heat generating/absorbing fluid through porous medium in a rotating parallel plate channel under the influence of uniform transfer magnetic field normal to the channel. The momentum equation for the flow is governed by the Brinkman’s model. The analytical solutions for the velocity and temperature distributions are obtained by making use of regular perturbation technique and computationally discussed with reference to flow parameters through the graphs. The skin friction and Nusselt number are also evaluated analytically and computationally discussed with reference to pertinent parameters in detail.
