Production process evaluation and improvement by using method of discrete event simulation

The label printing and packaging industry has a rapidly growing and evolving market in the world. The most important aim of the companies is to accomplish the demand and expectations of the customers in the market. Label printing houses have to improve their production process to produce fast and good quality products. Aim of this study is identifying bottlenecks, balancing production lines and improving system efficiency by using simulation. First, problems are defined in production system then processes are defined and conceptualized in an activity flow diagram. Demand arrival times, demand quantities, lead times, failures, demand product types and production times are observed and analyzed. Product types are divided into groups according to their production technics and also number of colors as they contain. Each process time of product type groups are examined and analyzed separately. Graphical and statistical analysis is done for each data groups by using standard statistical tools. Discrete event simulation model is created at Arena software and based on conceptual model after validation and verification test results, solutions for production problems and improvement of production process are suggested to the company.
