| dc.description.abstract | Not only occupying about 60% of area at Me Kong Delta region and about
12% area of Vietnam, sweet potato in Vinh Long Province has a remarkable
production, in terms of quantity which is 67.8% of quantity in Me Kong Delta and
about 26.9% of Vietnam in total. Sweet potato is considered as the representative
fresh agricultural product of the Me Kong Delta region. In the current time, supply
chain of sweet potato is inefficient in terms of outdated technology, lack of
management, and the issues of market. The dissertation research aims to improve
efficiency in management and to cut off the costs of operating supply chain in Vinh
Long. The objective of this research is to design the new supply chain of sweet potato
so that it meets demand, functions effectively and efficiently, and brings sweet
potato to customers with an acceptable price.
Data for designing supply chain of sweet potato in Vinh Long consists of two
categories: primary information from interviewing with local bodies, farmers,
traders, and experts, secondary data from the theoretical system of the supply chain,
from research, doctoral dissertation related to the supply chain and operational
efficiency of fresh agricultural products supply chain in Vietnam, especially in the
Mekong Delta region; and from consulting local experts in Vinh Long. The supply
chain model design is a process with two phases to support strategic decision. The
first phase is Multi-objective Optimization with two objectives which are
minimizing cost and minimizing transportation time. The solution of the first phase
was obtained by using CPLEX software. The second phase is Multiple Attribute
Decision Making (MADM) in selection process to select the location. In this stage,
the author use a special Analytic Hierarchy Process named Spherical Fuzzy Analytic
Hierarchy Process (SF-AHP) and Combined Compromise Solution (CoCoSo)
Algorithm in location selection.
The final output of the model is locations of all components in supply chain
of sweet potato, all production quantity and inventory. To accompany with
configuration of supply chain, management concepts are introduced and discussed.
