| Summary: | A new economic model for the evaluation of integrated Design, Production, and Logistic
Support Systems (DPLSSs) is designed and developed in this thesis. The DPLSS model was created
after a survey of Life Cycle Costing (LCC) applications revealed that no models for assessing
integrated design, production, and logistic support systems were available. The evaluation technique
the model is based on is called Life Cycle Value Assessment (LCVA). LCVA differs from
LCC in that it emphasizes consideration of life cycle revenues as well as costs.</p>
<p>
The system addressed by the DPLSS model has a life cycle which includes product design,
production capability design and construction, production, product distribution, logistic system
support and maintenance, and system disposal. The baseline production capability assumed when
developing the DPLSS model involves batch processing, forming the base material into individual
units, and performing detailed processing operations. It has also been assumed that items produced
are non-repairable.</p>
<p>
The DPLSS model facilitates the evaluation of new DPLSSs by leading managers through the
new LCVA methodology, A Cost Breakdown Structure (CBS) which is compatible with the
DPLSS life cycle has been developed as a basis for the model. This CBS is used to address DPLSSs
descriptively and nonnatively during LCVA evaluations.</p>
<p>A menu-driven computer program has also been developed to implement the DPLSS model
on an IBM PC. This program leads users through the new LCVA-based methodology, performs
economic and sensitivity analyses on their inputs, and then allows "what-if?â analyses on varying
system configurations to be performed.</p> === Master of Science |
