Actual time for tagk-aczqoplishment and actual dailyworkload performed for customer service, stock accountihg,-.and cost accounting sectionsof the Materiel Distribution Service were recorded. Two manpower prediction formulas,one based on time for task accomplishment and the other on workload act.mplished,were derived from the data. A significant difference was found between the pedictedmanpower requirements. The author concluded the formula based on workload was a -btterpredictive tool due to its inclusion of the minor tasks accomplished that were notmeasured by the task accomplishment model.

ACKNOWLEDGEMENTS
This project could not have been accomplished without the
help, advice and untiring assistance of many people. First, I
wish to thank my preceptor, Colonel Gerald C. Oliver, Deputy
Commander for Administration at the Colonel Florence A.
Blanchfield Army Community Hospital, Fort Campbell, Kentucky.
His leadership, guidance and support were invaluable throughout
this project.
The cooperation of all the personnel working in the
Materiel Distribution Service greatly enhanced the collection
of data and is deeply appreciated. Through observing their
daily routines, I was not only able to collect data for this
project, but also learn the practical side of operating an MDS
function.
I also have to acknowledge the young lady who had the
arduous task of typing this report and her untiring efforts to
complete the project on a timely basis. More importantly,
though, is Mrs. Donna Sanchez's friendly and energetic nature,
enduring the many changes that occurred while typing this
project, always looking on the bright side of things.
Finally, I cannot overlook my wife and two sons who have
endured so much while I was obtaining my education. Many times
my wife had to play the dual role of "father" and mother while
I was working on various projects. Their unceasing support at
home has made this project possible.

CHAPTER I
INTRODUCTION
Background
A valid concern of logisticians is how to get materiels to
the correct user in the right quantity and at the right1
time. The accomplishment of this goal not only leads to
operational efficiency but also helps to reduce costs by
minimizing the amount of stock on hand, theieby reducing the
potential for pilferage and limiting waste. To help resolve
this dilemma, the identification of internal inventory transfer
operations as an operating area has been recognized by
logisticians to integrate the physical distribution and2
materiels management operations within an enterprise.
In a hospital environment the internal inventory transfer
dilemma translates into a problem of moving supplies from a
warehouse or central storage facility to the various wards and
clinics in the proper quantity to insure medical support is not
interrupted by a stockout condition. To counter this problem,
many hospitals have integrated internal inventory transfer
operations into the logistical functions through the use of a
materiels distribution service - MDS (also commonly called a
supply point distribution center - SPD). Distribution of
materiel to the wards or clinics from this central storeroom is

generally accomplished by one of three methods: (1) the
"fetch-and-carry system"; (2) the Par-level stockage system; or3
(3) the cart-exchange system. The processes of these three
systems are illustrated in Appendix A.
In the fetch-and-carry system, the customer plays an
active role in ordering supplies. Someone on the using unit is
delegated the responsibility of maintaining adequate levels of
supplies, filling out appropriate requisition forms and
submitting the request to the central storeroom. The central
storeroom fills the request and delivers the materiel to the
user. Frequency of this process is dependent upon the actions
by the user, while the central storeroom plays a passive role
until activated by a supply request.
Par level stockage is based on es
