The purpose of this study was to produce a VCD on Design and Development of Textile Products from Surin Silk for the training program entitled “Design and Development of Textile Products from Surin Silk : From Folk Wisdom to Internationalization” The instruments of the study created by the researchers were : the VCD a learners’ test an experts’ evaluation form and a questionnaire on learners’ satisfaction. Fifteen people in Surin were randomly selected for the efficiency test of the VCD. The tests measuring E1 and E2 were taken after they had learned one lesson from the VCD. The result revealed that the VCD had the efficiency at 82.66 / 84.33 which was higher than the 80/80 criterion and was rated “much satisfied”.

The objectives of this research were to find the distribution of food demand for laying hens and to find the optimum amount of that food production which had minimum cost. The data consisted of customer purchase orders for the food of laying hens price of food for laying hens cost per unit for the food inventory cost related to food of laying hens in which the food was out of stock such as fine overtime urgent purchase for material. They were collected in 2008-2009 form a factory in Nakhonratchasima province. The collected data were analized in order to explore the distribution of the monthly food demand for the laying hens and to see the rate of inventory per unit. The results were used in the stochastic linear programming model for aggregate planning in which the optimum production minimum cost could be obtained. Programming algorithm in MATLAB and tools in Linprog software were used to get the solution. The distribution of the food demand for laying hens and the random numbers were used in the model. The study found that the distribution of food demand for laying hens every month has normal distribution (January to December). The monthly average amount of production from January to December were 10936.94 12913.74 11898.12 13096 15443.26 14916.33 10322.64 10818.21 11393.11 11700.72 9706.05 and 11702.05 respectively. The minimum total cost average for 12months was Baht 62422386.98.

The purposes of this research were to study demand forecasting and production planning. The case study company manufactured the fish sauce product that was made to stock. To design the system the sale data was studied in order to choose the appropriate forecasting technique for the sale data. After using the system with the company case study it revealed that the prediction system can forecast the production of 1126570 units in July 2008 whereas the total sales were 1134322 units. The difference was equal to 2718 units or 0.69 percent of the actual sales which was a total cost of 116280 baht which was more equivalent to the actual sales predicted by a sole experienced decision maker who predicted the production at 1274098 units. The difference was equal to 139776 units or 10.97% percent of the actual sales which mean 2096640 baht of total cost

Bagasse is a load of waste of caster sugar industry about 20 millions tons per year over 80 percents are used to be fuel and raw materials for the other industries. Anyhow much more bagasse is abundant. Then attention in textile industry application. Because of biodegradable and environment friendly. This research was studied about fiber separation and shockproof production from the bagasse. Fiber separation by chemical process. There are variable in amount of sodium hydroxide boiling time and produced to web by field latex 100 percents at 100 degree celsius. Physical properties of web such as thickness weight per unit area bursting and tearing strength was estimated. The appropriate condition for fiber separation as follows : sodium hydroxide 180 g/l for 2 hours. Average thickness is 2.83-2.90 millimeter. Average weight per unit area is 0.57 g/in2. Average bursting and tearing strength are 371.1 N and 756 mN respectively. The web is suitable for shockproof production
