To meet the immediate
environmental challenges and sustainable development, Closed-loop Supply Chain
(CLSC) management has become increasingly important and urgent. This is in lieu
with some severe problems such as global ecological damage, resource wastages
and shortages and pollution of the environment, and discretionary exploitation
of natural resources. On the other hand, re-manufacturing of used merchandise
and bringing them back to the market provides environmental and customer
benefits to Original Equipment Manufacturers (OEMs), in addition to cutting
back their production cost. This paper aims at evaluating the system behavior
of an electrical manufacturing company as a case of study, by using System
Dynamics (SD) simulating of Closed-loop Supply Chain (CLSC). VENSIM PLE
software developed the simulation model. Based on the initial result, customer
satisfaction and Green Image Factor (GIF) are lacking in the system. Therefore,
to tackle this issue, an improvement model with a collection center was proposed.
Results derived from the improved model presented a data of which the demand
backlog level fell by 21.19%. Furthermore, the customer satisfaction in the
system rose by 21.6%. In addition, as a result of an increase in GIF level from
14.80% to 48.1%, the return products rate rose from 184 items to 614. The
method in this research can be used to investigate a variety of CLSC systems
and their effects before implementing them in real life.
