... If body movement can be minimized for doing a job, then energy and time will be saved. Worker should be given rest in between work for removing tiredness, as a result work speed will be increased and total work output is more [32]. ...
In any production facility, process optimization plays a crucial role in enhancing the plant productivity. A lot of material flows through production and hence a large amount of capital is locked in it. At the same time, a significant amount of manpower is allotted for smooth regulation of production operations. Considering this, it becomes important to create a balance in man-machine interaction with respect to time and method of carrying out processes. This is achieved by conducting work study which is broadly classified as work measurement and method study.
Work measurement deals in estimating operation time by splitting the entire process into number of micro-operations. This is done by utilizing different studies such as stop-watch time study, predetermined motion time systems etc. As an outcome of work measurement, it becomes easy to determine the standard time for carrying out a process and unnecessary delay time is eliminated. At the same time, motion study or method study deals in study of methods of carrying out any process via. operations. These methods are analysed by breaking down into micro-motions and eliminating waste movements. Movement of men and materials involve a significant amount of time and corresponding cost and therefore method study helps in evolution of best possible methods of carrying out any work.
This work deals in optimizing the production processes of a plastic packaging material manufacturing industry, Vaibhav Plasto Printing and Packaging Industry located in MIDC Hingna, Nagpur. The analysis is carried out in the three important sections of the industry namely PVC extrusion, printing and dispatch section using stop watch time study, time study via. video recording etc. At the same time, methods were observed and improvements are suggested in production methods. A standard operating procedure (SOP) is also proposed for dispatch section. Finally, die changing process is optimized in printing section by using single minute exchange of die (SMED) concepts.
Keywords: Time study, Method study, single minute exchange of die, process flow etc.
... The latter deals mostly with investigation of ineffective time associated with a job, and setting time standards to execute an operation by conforming to the standard method [7]. This also results in a systematic investigation pertaining to all factors that can impact the production efficiency and economy pertaining to the case being studied, which effectively allows achieving productivity gains [8]. ...
... Productivity enhancement can be achieved by getting rid of inefficient methods, decreasing work content as well as effectively making use of manpower, machines, and materials. Also, it can be realised in multiple ways, such as by decreasing the production unit cost or decreasing the production work content, by increasing the products' valueadded content [8][9][10][11][12][13][14], by line balancing with respect to the production line, or via combination of all of these [9][10]15]. Enhancement of productivity can be defined as a continuous improvement process that is applicable to many kinds of activities [7][8]11,[16][17]. ...

Today with a rapidly changing world and markets, SMEs are facing a critical challenge to remain competitive in the business market. In this paper, a case study of the SMEs food industry is presented. Work study methodology was embedded in the strategy to improve the productivity of the soya sauce enterprise. The sample size required for the study was calculated and random observations were determined through a work sampling technique to achieve a 95% confidence level. The result from this study reveals that work sampling data can be used as a reliable estimation for identification of any potential bottleneck as well as idle time in the factory. The process flowchart at the filling and capping terminal were examined and the travelling distance was optimized to 12.5 feet from original distance of 17 feet. The modified plant layout significantly improves the people flow, production material handling, work safety, space utilization, and better working conditions. The survival of SMEs is critical as this sector contributes 38.3% to Malaysian‘s gross domestic productivity (GDP). Thus, these findings demonstrated that enhancing the productivity of SME food industries is effective through a work study. However, the successful adoption of this approach is mostly because of top administrative involvement and the participation of all staff members.
ABSTRAK: Pada hari ini, dengan perubahan pesat dunia dan pasaran, SMEs berhadapan cabaran getir bagi terus tetap berdaya saing dalam pasaran perniagaan. Kajian ini membincangkan berkaitan kes kajian SMEs dalam industri makanan. Kaedah kajian kerja telah diguna pakai dalam strategi bagi meningkatkan pengeluaran sos soya. Saiz sampel yang diperlukan bagi kajian ini dikira dan pemerhatian rawak diperoleh melalui teknik persampelan bagi memperolehi 95% tahap yakin diri. Hasil keputusan kajian menunjukkan data persampelan boleh digunakan sebagai anggaran boleh percaya bagi mengklasifikasi kemungkinan kesesakan dan juga masa terbiar dalam kilang. Proses carta alir pada terminal isian dan penutup telah diperiksa dan jarak perjalanan dioptimumkan pada 12.5 kaki dari jarak asal iaitu 17 kaki. Ubah suai susun atur kilang dapat memperbaiki dengan ketara aturan pekerja, pengendalian bahan pengeluaran, keselamatan kerja, pengunaan ruang tempat kerja dan persekitaran tempat kerja yang lebih bagus. Kemandirian SMEs adalah sangat kritikal kerana sektor ini menyumbang 38.3% kepada Keluaran Malaysia Dalam Negara Kasar (KDNK). Oleh itu, hasil kajian menunjukkan peningkatan produktiviti industri makanan SMEs adalah berkesan menerusi kajian ini. Walau bagaimanapun, keberhasilan kaedah ini berpunca daripada keterlibatan pentadbiran dan seluruh anggota pekerja.
