e Study Objective (e): Assess financial feasibility of the MOBS 
concept in comparison to an existing alternative. 
1.3. Approach 
The morphology of large scale engineering system development pro- 
vides the approach for this study. The logic in this approach for 
determining the feasibility of MOBS and comparing its performance with a 
likely alternative basing system is represented graphically in Appen- 
dix B. Accordingly, the following sequence of specified tasks was 
executed in order to satisfy the purpose of the investigation: 
Task (a): In conformance with the CILTS security assessment and 
other related strategic studies, identify an envelope of security envi- 
ronment factors (Section 2.0) which serve as descriptors for character- 
izing a threat profile and simulating a generalized typical Third World 
crisis situation, circa year 2000. 
In parallel with the crisis simulation, those same strategic 
descriptors enable identification of effective basing needs within the 
context of the projected security environment and specifically, the 
crisis scenario. The effective basing needs are to be accommodated by 
the modularized ocean basing system or its most likely alternative. 
Further, in order to demonstrate the full range of identified basing 
needs and define related functional requirements within the scenario, 
the U.S. response is executed in a combined operation of land, sea, and 
air forces with a single unified support structure. As a result, the 
logistic support can be treated as a large-scale system optimized for 
cost-effectiveness within constraints of joint multi-service Warfare 
Systems Architecture and Engineering in the year 2000 time frame. 
Finally, this same scenario, which confirms functional basing require- 
ments, also serves as the context for evaluating MOBS and comparing it 
with a most likely existing alternative. 
Task (b): Resolve previously identified effective basing needs by 
defining system performance objectives including conditions at the
