Problem-solving and ongoing procedure enhancements are key elements to obtaining quality improvement in business operations. Many process and machine improvement strategies have been suggested and implemented in organizations, where define, measure, analysis, improve and control is mostly applied. Here we aimed at improving the machine productivity of assembly line in a cotton ginning assembly line in an Industry. The tool which is used to improve the productivity of assembly line are time study and method study. Based on this, the study provides data of time required for each assembly processes, sequence of each operations and flow of the product in assembly line. The present study has been done at an industry, a leading manufacturer of cotton ginning machine. The aim of the study is to identify the various problems on the assembly line which causes unnecessary delay in the operations. The problem is found in the assembly line and is solved by work study techniques and it is found that cycle time of bottle neck operation was reduced by 40.08 % per trolley.

Roller hemming is usually applied for hang-on-parts such as hoods, doors or trunk-lids which all have complex non-linear geometries. The flange is often hemmed along both surfaces and edges which have 3D curvilinear shapes. Minimization of hemming defects and the requirement to improve cycle time of the roller hemming process are essential for roller hemmed hang-on-parts in the automotive industry. Different systems such as the driven roller hemming provide the possibility to increase the strain rate without loosing surface quality and dimensional stability. Investigating the influence of friction during roller hemming, results will give an understanding of the advantage for mentioned roller hemming systems.

Balancing Efficiency

Balancing assembly line in a mass production system plays a vital role to improve the productivity of a manufacturing system. In this paper, a single model assembly line balancing problem (SMALBP) is considered. The objective of this problem is to group the tasks in the assembly network into a minimum number of workstations for a given cycle time such that the balancing efficiency is maximized. This problem comes under combinatorial category. So, it is essential to develop efficient heuristic to find the near optimal solution of the problem in less time. In this paper, an attempt has been made to design four different genetic algorithm (GA)-based heuristics, and analyze them to select the best amongst them. The analysis has been carried out using a complete factorial experiment with three factors, viz. problem size, cycle time, and algorithm, and the results are reported.

This research objective is to improve the productivity of cookware assembly line by means of time and distance reductions. The motion study and line balancing techniques were applied to the entire assembly operations. A bottle neck was identified to where the operation with inadequate machine layout and workplace organization, including the unbalanced workloads. The new workplace layout and new working method for operators were designed and implemented as well as balancing the assembly line. Specifically, the conveyor speed and duration between the consecutive workpieces in the production line were adjusted to 0.10 m/s and 50 cm, respectively. The number of operators needed in the process can be reduced from 14 persons to 11 persons. The cycle time for assembling process is decreased from 12 to 5 second.
