With industrial revolution and growing competition in the production area specially in the automotive industry, focus shifted towards efficiency of the production area. The goal was to make the production area more efficient which includes the machine, work force etc. For the production unit to be efficient it is very important that machines work efficiently without stopping. In order for the machine to work without stopping it needs to have a continuous supply of the raw material and the packaging material. But as it is automotive industry there is various kind of raw material and packaging material, so it is very important to understand, measure and plan the requirements accordingly. The problem faced in improving the Overall equipment effectiveness was the machine has to stop multiple times because of the lack of raw material and packaging material which result into poor OEE of the production unit. In this report, it is focused on increasing the overall equipment effectiveness of the plastic injection production unit of the automotive industry by first understanding the main activities and actors in the production unit by using Unified Modelling Language. After understanding the main activities and the flow of activities the requirements of the machine is measured based on the production plan received from planning department. The logistic plan is been developed focused on the needs of the machine (Raw material and packaging material). The hours of work is been described so based on the cycle time the quantity to be produced, quantity and type of the raw material and packaging material is been calculated and forwarded to the production logistics so that based on that plan they can arrange the supply to the machine. Plan Do Check Act methodology is been used in implementing the logistics supply plan. As a result of this plan it can be seen the drastic change in the increase of the Overall equipment effectiveness. The OEE is been measured without the supply plan which resulted into 70,27% after implementation of the supply plan there is a big increase in the OEE of the same production area of 82,34%, so there can be clearly seen the increase of 12,07% in OEE by just implementing the logistic plan. Thus, this report helps to understand the importance of logistic supply plan and UML in order to increase the Overall equipment effectiveness of the production area.
