 I will use a Poisson distribution that makes sure that the “CUT RODS” process has enough “RAW RODS” to cut, because I am only asked to look at the internal processes. But based on the conclusion I will also give a recommendation about inventories and ordering of “RAW RODS” in the conclusion.

 We use a transform operation “CUT RODS” that needs 1 resource “Cut operator”. The entity “RAW ROD” is transformed in a “CUT ROD”.  The resource works two shifts. Because the reliability is 100% we don’t need an extra branch for defaults.

 When we run the model in the setup I explained earlier we can see several problems that occur in the process. This table shows the biggest problem in the simulation.

 The “Cut operator” and “Forging machine” are always busy because of the huge inventory created by “RECEIVE ROD” and “RECEIVE FORGINGS”. But the other machines and operators are “Idle” a lot of the time. When we visualize the simulation and look at the data we can see the reasons for this problem.

	A good solution for the problem is to batch the first part of the internal process, and use the “CUT RODS” as a pacemaker. This balanced batch reduces inventories and lead time. The idle time is reduced to a minimum so there are no big losses. The second part of the solution in to include the painting to the own processes. The batches are handled by the painting department in for example 1 day. A good suggestion might be to do the painting or drying overnight or when the other processes are down. The ordering and receiving of inventories should be adjusted to the pacemaker, “CUT RODS” in order to avoid excessive inventories of raw material. This report and recommendations will strongly improve the overall efficiency of the company.
