Abstract

The uncertainty of the production system arises in the form of production system disturbances. PT ABC is a company that produces heavy equipment components. Based on preliminary research, it is known that there is a need to solve the problems of production planning  and inventory control (PPIC) in the company related to the disturbances of the production systems faced by the company. The purpose of this study is to map the production system disturbances and provide solution to improve the function of PPIC in facing the disturbances of the production system at PT ABC. Based on the Key Performance Indicator (KPI) of PPIC, we do mapping of production system disturbances occurs. Next, the data processing and analysis are carried out descriptively and by using the Classification Technique - Association Rules. The disturbances mapping results show that the high severity disturbances associated with the MRP PPIC Model, with the type of disturbances of raw materials having a high impact on KPI. The production process cannot run according to planning and scheduling because the flow of information that is less integrated between divisions causes each division to process based on their respective policies. The company needs an improvement in the MRP system in releasing production and ordering of materials, and also control the disturbances of the production system.
