Abstract
This research was conducted at an electronic field assembly company. The company implements a production system that starts from semi-finished goods to finished products. The problem of the company is the imbalance of the production trajectory. The track balance in the final assembly will affect the amount of product that can be produced. The unbalanced track conditions resulted a bottleneck condition in the material flow from one work center to the other, resulting in delay time on the production floor. The problems are caused by large cycle times, thus resulting in different production capacities for each workcenter. The implementation of the theory of constraints is to identify the existing constraints and to obtain the optimum amount of workcenter as well as to allocate elements of activity in the workcenter, thereby improving the efficiency of the production line.. In actual trajectory there are 7 work centers with track path efficiency 59,80%, balance delay 40,20%, and smoothing index 74,47. The result of balancing in the production line using theory of constraint method obtained the repair solution by number of work center as many as 5 work centers with track efficiency value 88,65%, balance delay 11,35% and smoothing index 17,07.
Highlights
The balance of the production process assembly line in the mass manufacturing industry is an important part of the production process
Track balance in the assembly process will affect the achievement of production targets
The theoretical steps of constraints consist of five steps: 1. Identify a System Constraint. This stage requires observation of the problem on the final assembly process to be solved. This requires cause-and-effect to identify the basic causes of the imbalance of the assembly line path to the core problem
Summary
The balance of the production process assembly line in the mass manufacturing industry is an important part of the production process. This is related to the existence of several jobs that are grouped in several WC (work center). The operator's ability to do assembly activities will affect the number of products in each process. The assembly time of each work element is determined by the length of time required in the assembly. Track balance in the assembly process will affect the achievement of production targets. Unfulfilled production targets will cause losses for the company
