The implementation of milk-run in Indonesia has been started since 2005. As a developing
country, there is a challenge to operate milk-run smoothly especially in urban area due to
severe traffic congestion and unfavourable road condition in some areas. This research aimed
to analyze the practice of milk-run operation in one of the biggest Japanese automotive
companies in Indonesia. Transportation Value Stream Mapping (TVSM) is applied in order
to perform just-in-time delivery in the supply chain before operating milk-run. It is discussed
that this company still need to continue in improving milk-run operation. The operation
system needs control and integration from manufacturer, supplier and logistics partner.
The advantage of milk-run operation is cost reduction and also support green logistics in
decreasing emission of carbondioxide (CO2) by reducing the number of trucks used.
The problem of sequencing jobs on a single machine to minimize total cost (earliness and
tardiness) is nowadays not just important due to traditional concerns but also due to its
importance in the context of Collaborative Networked Organizations and Virtual Enterprises,
where precision about promptly responses to customers’ requests, along with other
important requirements, assume a crucial role. In order to provide a contribution in this
direction, in this paper the authors contribute with an applied constructive heuristics that
tries to find appropriate solutions for single machine scheduling problems under different
processing times and due dates, and without preemption allowed. In this paper, two different
approaches for single-machine scheduling problems, based on external and internal
performance measures are applied to the problem and a comparative analysis is performed.
Computational results are presented for the problem under Just-in-Time and agile conditions
on which each job has a due date, and the objective is to minimize the sum of holding costs
for jobs completed before their due date and tardiness costs for jobs completed after their
due date. Additional computational tests were developed based on different customer and
enterprise oriented performance criteria, although preference is given to customer-oriented
measures, namely the total number of tardy jobs and the maximum tardiness.
