Additionally, at the point of debarkation, all of the sectionalization and transport preparation will have to be reversed, meaning the receiving end must have the capability to restore, and verify, the product’s operational state.
Mission frequency and duration From an operations support standpoint, mission frequency and duration define the support resources needed to sustain operations. This factor would include rearm/refuel, emplacement/displacement, mission profile changes—in short, those activities which are conducted as a normal part of operations. Meeting turn-around time intervals within the anticipated mission frequencies imposes performance requirements on the support system requiring it to respond to the projected operational demands of the product.
Quantification of support resource requirements is directly related to the characteristics of a product’s design and the frequency and duration of the missions which it performs. Mission frequency and duration and the reliability of the product provide the initial basis for determining the range and quantity of support resources that will be required. Human systems integration Human beings are an integral part of the performance characteristics of the total system. The ease or difficulty of operating and maintaining a product with acceptable results imposes specific requirements on the product, software, and support system designs.
A product which is difficult to operate by virtue of the complexity of its mission requirements or its design characteristics requires individuals with greater cognitive or manual dexterity skills than one which is less complex. The same is true of software and support. The existing force structure and support infrastructure into which the product will be introduced have available a complement of human capabilities and limitations.
For the designs of the total system components to minimize their impact on the existing infrastructure, human capabilities that are available and the limitations that exist must be identified so that these considerations are included in the analysis of design alternatives. Anticipated service life The planned service life of a product will have significant impact on the total system design alternatives considered and the life cycle cost associated with each.
