The work study done on the assembly line mainly deals with the time and motion study and work measurement to determine total time required to manufacture one engine and then applying lean manufacturing methods to fulfil the problem of productivity improvement. The first step of the work study will be the study of current process of production. After the collection of current process, time of all the assembly tasks involved is reduced using time study techniques. Along with time study, process analysis will be carried out which will give us idea of number of non-productive tasks carried out during the assembly and thus reducing them. Hence by implementing Value Stream Mapping method for lean manufacturing and reducing the non-productive tasks, the project will display the effort of increasing the productivity of the manual assembly line of Petter engine.

This paper applies the methods of Work Study to a certain hydraulic component company. We apply the work measurement method to measure the work time of various stations of assembly lines, and to find out both the bottle neck stations and the superfluous capability stations effecting on the line assembly capability. Basing on the principle of ECRS (Eliminate, Combine, Rearrange, Simple) and the line balancing theory, this paper provides the line balancing schema, including the improvement of the existing equipment, the reallocation of the work content for relative stations, the adjustment of the equipment and workers of some stations, the reduction of machine working time of some stations and the change of assembly line layout etc. After being improved, the work time of the bottle neck and other processes are controlled near the Taking Time. Comparing with the former assembly line, the production capability of assembly line improved up 45.6% and workshop condition is also improved.
