This paper discusses about a company that adopts make-to-order strategy because
the company does not have enough fund to provide raw material. The raw material is ordered
when the order is received. It occurs a very long customer lead time due to the production
process must wait for the arrival of material. Consequently, the company cannot meet the
customer order at the due date, and the company should give a discount of 25 - 30% of the total
purchases. This research aims at reducing customer lead time by determining a decoupling
point. The result shows that the decoupling point is placed between the procurement of raw
materials and the manufacturing process. The decoupling point denotes a boundary between
the make-to-stock strategy in the previous process, and the make-to-order strategy for the
process afterwards. The lead time customer is then considered start from the decoupling point
to the due date.

This paper aims at an assessing of a supply chain performance by adopting the Supply
Chain Operation Reference (SCOR) Model. The supply chain activities are divided into five
core processes, i.e. plan, source, make, delivery and return. Each level of the SCOR model is
weighted using Fuzzy Analytical Hierarchy Process (FAHP). The mapping of SCOR Model
consists of 5 core processes at 1st level, 21 performance matrices at 2nd level, and 28 Key
Performance Indicator (KPI) at 3th level. The result shows that the supply chain performance is
68,231. Referring to the performance indicators, the performance achieved by the supply chain
at this time is in the average category. Proposed improvement strategies are designed based on
lean supply chain principles, through the implementation of Gemba Kaizen which consists of 17
proposed strategies.

In the batch production, the use of a single machine for several stages of the processes
will result in waiting time of production batch to be long. It will cause an increase in work in
process (WIP) inventory cost. CNC-machining centre is a type of CNC machine that can carries
out several stages of processes singly. In some cases, this machine is often single used to make
a product through several stages of processes, from raw material to end product. One of the
reasons to use a single machine is to avoid transfer from one stage (machine) to next machine.
However, single use causes inventory to accumulate due to long waiting times. The objective of
this research is to reduce the WIP inventory cost at the CNC-machining centre. Scheduling to
minimize WIP inventory cost is done through two steps. First step, divide number of stages of
processes to be assigned to m serial CNC-machining centers. Second step, determine transfer
batch size is smaller than the production batch size to be transferred to the next stages. The results
of this research indicate that there is a reduction in WIP inventory cost by 53.47 percent.
Scheduling multi-stage batch production on m machines with small transfer batch size will
reduce WIP inventory cost.
