Summary: | 碩士 === 國立臺灣大學 === 商學系 === 82 === Peter F. Drucker said that logistics is the "Economy''s Dark
Continent".In American business,management looks to logistics
as the last frontier of cost reduction.It''s the same in today''s
Taiwan,logistics has played a key role in winning a success for
a business.This study intends to solve a system design problem
in a logistics system by developing a mathematical model.The
problem is to assign a set of customers,e.g. retailers, to
several distrbution centers.Initially,the scope of this study
is confined.Then two different approaches ,Lagrangian relaxa-
tion(LR) and Aggrgegation/Disaggregation(A/D),are introduced
and tested on three different parameters.These three parameters
includes numbers of customers,numbers of distribution centers,
slack ratio.The conclusions of this study are presented as
follows: 1.A solution of LR is better than that of A/D in most
cases. 2.By increasing the numbers of customers or slack ratio,
while holding others constant,an A/D solution will be closer to
a LR solution. 3.By increasing the numbers of distribution
centers,while holding others constant,the gap between an A/D
solution and a LR solution becomes wider. The above conclusions
suggest pertinent approaches for a decision-maker under
different parameters.They can also provide an useful reference
for constructing a logistics decision support system.
