Proportional plus integral controller has been widely used in permanent magnet synchronous motor (PMSM) drive system due to its simple structure while achieving zero steady-state error. However finding out the optimal parameters of the controller is not an easy task. For this reason this paper presents an automated optimization of proportional plus integral controller for permanent magnet synchronous motor drive system using genetic algorithms. Simulation and experimental results verify the effectiveness than ones of the trial and error method.

R & D PRECISION CO.LTD manufactures various types of work. Yet there were defects of work in previous working and the company was unable to deliver products to customers as required and some might have been destroyed. As the information referred to the waste detected each month from January 2014 to June 2014 it is found that the volume of defect rate was 9.56 percent resulting in losing cost of production and other business opportunities. This research aims to reduce waste in the production of high precision with lean concepts. The study starts from the analysis of employees working information by creating a value stream mapping. The study found that cylindrical grinding takes the longest time. Then the study explored and determined the root cause of the problem by using a Pareto Diagram together with a Fish-Bone Diagram to analyze the minor causes. It is found that most wastes are caused by measuring control especially for the work that has a shaft hole with thickness of 2.25 mm. Thus the study and experiment were conducted to determine the flow rate of the coolant for the work piece in the cylindrical grinding machine and a fixed value is the rate of decreasing the size of work speed of stone wheel and work type of coolant and type of grinding stones. The goal is to reduce waste by not less than five percent and to improve the process of reducing waste effectively which will affect the environment having lesser wastes from production. It also supports competitiveness and rapid change of industry manufacturing highprecision parts in the future even better.

The objective of this research was presented a decision support making process for efficiency improvement of drinking water processing using retrofit technique for machine and equipment rehabilitate. This methodology was applied Analytic Hierarchy Process (AHP) for selecting an appropriate maintenance sub-contractor. To complete the research existing water purifying machine and tools were inspected to assess its capacity. Future capacity of the purifying machine was also identified. Consequently machine and tools such as water tank and water filter were inspected for retrofitting for the example water tank water filter water quality control and bottle packing. Finally the analytic hierarchy process was utilized to select the most appropriate maintenance sub-contractor. In this process both qualitative and quantitative processes were analysed. The result of this research has been found that this multicriteria decision making process could be used to support the decision making investment process of water purification retrofit unit at Faculty of Engineering Rajamangala University of Technology Phra Nakorn efficiently. Furthermore it could be reduced bias from decision makers while the decision was accepted by all stakeholders.

The main purposes of setting up food vocational training guidelines for members of Cha-am Municipality Phetchaburi province are: 1) to study needs for food vocational training; 2) to compare different status among group members as well as opinion about food vocational training; and 3) to set up food vocational training guidelines for members of Cha-am Municipality Phetchaburi province. A total of 224 populations in the stud y consist of 5 groups of housewives who are members of food product processing group in Cha-am Municipality Phetchaburi province: Huay Sai Nue Chili Paste Elderly Group Huay Sai Tai Housewife Community Group Ban Yai Cha-am Dried Fish Chili Paste Elderly Group Ban Sapan Hin Group and Look Phra Mae Phosop Vocational group of Cha-am Market community. Tool used in the survey study are questionnaire and interview. Data are analyzed for percentage mean standard deviation F-test ANOVA (One-Way analysis of variance) and the Scheffe method for paired mean comparison. Results of the study show that members of Cha-am Municipal housewi fe community group need to have a place for group training for the duration of 3 days in March particularly in the morning section (09.00-12.00am) of Monday to Friday. They also need public relation of training through broadcasting tower self-application method site study tour and certificates ceremony. The benefit gained is harmony among group members. Training courses of their interest are chili paste making ready-to-drink juice and food processing respectively. Members with different status in group show statistical difference in opinion towar ds needs for food vocational training at significant level of 0.05.
