In Operations Research, the equipment replacement process is usually modeled in discrete time. The optimal replacement strategies are found from discrete (or integer) programming problems, well known for their analytic and computational complexity. An alternative approach is represented by continuous-time vintage capital models that explicitly involve the equipment lifetime and are described by...

The equipment lists provided in this article are not intended to be proscriptive or definitive. They are simply an illustration of the logical application of equipment selection and packing principles according to the likely needs of the casualty. Although trained personnel with relatively little equipment can perform simple interventions, optimal care requires some advanced techniques and good...

The use of durable medical equipment in the home, while not a recent development, was formally recognized by the Congress with the passage of the original Medicare legislation. Since that time the statute has been amended to provide for a more workable, economical, and desirable interface among the administrative, supplier, and user communities. To assist in achieving this end, a research proje...
