This research considers the vehicle routing problem in a specific bakery making company where is located in Bangkok. This company has to produce and deliver the bakeries to its customers everyday. Until now this mentioned company generates the delivery’s route by using the experience taken from the company’s truck driver. The company has to daily use the route with unnecessary long distances. According to the given statement this research aims to develop algorithm to generate the delivery route for this company by using the Genetic Algorithm in order to minimize the transportation distances.

In this paper a CPW-fed slot antenna for wideband application was designed and simulated. In order to examine the performances of this antenna a prototype was designed at frequency 2.4 GHz and simulated with various width of slot antenna in both sides for input impedances matching and simulated by IE3D software package of Zeland. The simulation result of bandwidth is 1.65 GHz (2.1{3.75 GHz) which covers the standard frequency of IEEE 802.11 b/g (2.4{2.4835 GHz) and Wimax (2.3{3.6 GHz). With these performances the proposed antenna can be used in wideband applications.

The objective of this project Photocopying Document Management System managed photocopying requirements of employees in Faculty of science. This system can used to track and manage photocopying tasks and store photocopying requirements. Moreover the system can summarize total number of paper usage and calculate statistic of user’s satisfaction. The Photocopy Document Management System is a web application which is developed by using PHP and MySQL. The overall of Photocopying Document Management System user’s satisfaction is at the greatest level which is the total average at 4.79 and the standard deviation at 0.12. the system can perform all of expectations.

The Online Equipment Inventory System for Subdivision of Supplies Case study at Faculty of Science and Technology is developed based on web application by using PHP and Laravel framework. The purposes of this system are firstly to systematically manage the database system of the asset equipment in the Faculty of science and technology. Secondly to increase the searching process rapidity and to create the summarize reports in PDF format. Lastly to produce the QR code for verified the asset equipment. This system is consists of the administrators and system users. In the part of satisfied evaluation the system is evaluated by the example target officers group. The overall result of satisfaction score is 4.10 which means the system can fulfill the requirement in a good level. Moreover when considering in each part of satisfaction; 1. design part 2. efficiency and functional part and 3. system satisfaction part the result scores are 3.96 4.18 and 4.06 consequently. In conclusion the Online Equipment Inventory System for Subdivision of Supplies Case study at Faculty of Science and Technology is work properly.

The purposes of this research were : 1) to study of factors personal the Demonstration School of Ramkhamhaeng University 2) to study food buying through online applications 3) to study factors of marketing mix towards buying food through online applications 4) To study the relationship between personal factors to buy food through online applications of the Demonstration School of Ramkhamhaeng University and 5) to comparison of opinion toward marketing mix towards buying food through online applications by personal factors. The samples students are studying in high school of the Demonstration School of Ramkhamhaeng University and never buy food through the applications online of 226. The instruments used in research questionnaires and interviews. The statistics used for data analysis were frequency percentage mean standard deviation Chi-square values and One Way ANOVA. The results showed that: 1) Most students were male 18 years of age by studying high school grade 6 and receive money from their parents for about 201-300 baht per day. 2) Most students purchased food Skootar by a full set this was why they had ordered food restaurants and a variety of food items in order was to feeding each paid 200 baht the students were ordering food when a new food product the purchase of food for every taste while students can be taken food delivered within 31-60 minutes and the most important in the fresh new foods. 3) Analysis of the data on the opinion toward was marketing mix towards buying food through online applications of the Demonstration School of Ramkhamhaeng University found that overall; students have commented on the high level the first two items in order from most to least found the side with the highest mean score was the distribution the second was the price and the minimum personnel. 4) Relationships between personal factors as gender age education and the money received from parents to buy food through online applications of the Demonstration School of Ramkhamhaeng University found that was relationship the statistical significance level. 05. 5) Comparison of opinion toward marketing mix towards were buying food through an online application by personal factors were found Gender age education The money received from parents of different. Levels opinion toward marketing mix used to purchase food through an online application not different the statistical significance level. 05.
