The purpose of this research is to study productivity improvement at electronic parts’s assembly line finding the work stations with work station time longer than takt time. This research applied the 5W1H technique as a tool to problem analysis fundamental of hand motions to improve productivity. The study found that the assembly line consisted 15 work stations and a cycle time of 12.0 seconds which greater than the takt time which was 10.5 seconds. The work station time no.6 took longer than the takt time. The fundamental of hand motion technique was applied. By separating or eliminating the fundamental of hand motion did not affect the performance of the work stations. By being integrated the fundamental of hand motion with previous work station or next work station. As a result of research is the new cycle time of this production line is 10.0 seconds the production line capacity increased from 300 pieces per hour to 360 pieces per hour 20 percent increase

Thailands food processing industry is a important driving force in the economy of the nation. Their attractiveness of the industry dynamically generated employment and the intensity of competition at the same violence that increased its competitive advantage in the industry its important to bring the success and survival of a business. Earlier this competitive advantage has been studied and discussed widely both a cost advantage and the advantage of making a difference products and services. Currently there are more studies on the part of the competitive advantage that is consistent with the competitive situation that is highly dynamic. In this study was to review the literature that relevance to the dynamics competitive advantage in the food processing industry in Thailand. Therefore this article is useful for entrepreneurs executives in food processing industry as well as for the scholars who are interested in this line of research.

The purposes of this research were to design and create dyed silk yarn and cotton yarn machine for community enterprises of Ban Na Pho woven group Na Pho district Buriram province. All materials were made of stainless steel and the principle of rotation of the yarn skein which was hung with spindle yarn inside the dye tank. Dyeing process began by mixing color tanks in the exterior size for diameter ๓๐๐ mm. Adjust the temperature inside the dye bag by the boiler was attached below. Using pump in dye tank for rotating the heat with stainless steel pipe in ๑๑/๒ inches and ๓ inches x ๑/๒ inches and the rectangular tank was ๖๐ cm. wide ๙๐ cm long and ๑๖๐ cm. high. It had ๕ mm. of plastic lid cover in front of and a channel that looked at the attachment of color yarn. The lid had ๒ levels adjustable lift spring lock and ๒-axis spindle yarn. It was triangular shaped drilled holes spray to ๑ mm. on the spindle with a diameter of ๑๕ cm. and ๖๐ cm. long rotating at ๑๐ rpm strength by using electric motor size ๐.๕ HP used ๒๒๐ volts. It could be rotated left and right with the gear ratios around ๒๐:๑ ๒ adjustable that were automatic with programming on the control box and simple pattern. the spray dyed paint had ๑ liter water pump to control pressure valve for opening and closing to dyed water flow regularly by the heat from the LPG gas with a head size of ๓๐ cm. and adjust the temperature up to ๑๒๐ Celsius degree. It was showed the temperature measurement of water dye with pressure gauge and temperature gauge. The efficiency of this dye can be dyed silk yarn and cotton yarn per ๕ kg. to ๑๐ kg. which was a medium-sized textile production to the local community enterprise and applied in the preparation of yarns before dying such as peeling glue and bleaching.
