The problem of relating intermodal cargo container cost, weight, and useable volume to container size, configuration, loading, and construction type is handled by comparing simplified preliminary container designs. To facilitate comparision, a common container base and panel supporting framework is assumed, with panel weights added to obtain total container weight. The panels for these designs are obtained through computer programs which optimize the panels with respect to weight through a stress-limited beam approach. These relationships are graphically presented for a variety of parameters. It is concluded that true intermodal containers meeting both the high-g requirements implied by air liftability and the versatile handling requirements of commercial containers can be expected to be somewhat heavier and more expensive than current commercial containers. The more expensive constructions can reduce this weight difference while retaining high interior volume, but cannot influence the strong effect of the handling penalties without an extensive test program to determine the feasibility of the lightened construction. If extremely light containers are needed to suit the air mode, consideration should be given to limiting handling capabilities to top-lift only. Author
