described how the Internet enables a new supply chain paradigm, a push-pull paradigm that replaces the traditional push model. In the past, most companies operated by forecasting long-term demand, mass-producing inventories of product to fulfill the anticipated demand and then "pushing" the inventories on to the customer. The disadvantage of the push model is that production decisions are based...

Bone screw fixation can be estimated with several test methods such as insertion torque, pull-out, push-in and bending tests. A basic understanding of the relationship between bone microstructure is still lacking. Computational models help clarify this relationship. The objective paper to evaluate homogenized finite element (hFE) pull-out. Experimental pull-out tests were performed on three mat...

In this paper, the effect of the crack on dynamic behavior of cracked micro-beam in the presence of DC and AC loads are investigated. By applying the residual axial stress and fringing field stress, a nonlinear analytical model of cracked micro-beam is presented and crack is modeled by a massless rotational spring. The governing equation of the system is solved using Galerkin procedure and shoo...

The terms pull and lean production have become cornerstones of modern manufacturing practice. But, although they are widely used, they are less widely understood. In this paper, we argue that while the academic literature has steadily revealed the richness of the pull/lean concepts, the practitioner literature has progressively simplified these terms to the point where serious misunderstandings...
