การวิเคราห์ความน่าเชื่อถือได้ในการทำงานของเครื่องจักร และหาสาเหตุของเครื่องจักรเสีย: กรณีศึกษาโรงงานผลิตชิ้นส่วนรถยนต์

This research proposes reliability analysis in order to find the probability that a machine will work properly the failure rates of a machine and the factors related to the failure rates. The data were collected from 8 types of machines in an autoparts manufacturing factory. They consist of the times measured from the first day of the study until the machine produces defective product workers and production steps. The study duration is 90 days. The results show that the probability that the machine type 4 will work properly more than days is 0.40 machine type 5 more than 68 days is 0.32 machine type 6 more than 72 days is 0.31 machine type 8 more than 85 days is 0.26 machine type 9 more than 109 days is 0.80 machine type 10 at more than 52 days is 0.38 machine type 11 more than 71 days is 0.32 and the probability that the machine type 12 will work properly more than 85 days is 0.26. The failure rate of the machine type 4 at day 51 is 6.61 machine type 5 at day 68 is 1.61 machine type 6 at day 72 is 0.77 machine type 8 at day 85 is 1.26 machine type 9 at day 109 is 1.31 machine type 10 at day 52 is 0.92 machine type 11 at day 71 is 1.24 and the failure rate of the machine type 12 at day 85 is 2.15. The factors influencing on the failure rates are worker group 2 and production step 3 at the significance of 0.05.

Knowledge and management of software requirements
Knowledge and management of software requirements

In software engineering requirements from customers users and stakeholder are initial information for software development process. The requirements elicited and gained are defined classified refined and stored systematically according to needs management principles. Therefore the requirements would be correct and ready to be used in the next step of development process. This process is called Software Requirements Engineering. If the gained software requirements are incorrect lack quality or are managed unsystematically they could lead to project failure and low-quality software product which cannot meet the needs of users and stakeholders. For these reasons this article proposed an overview of software requirements and an approach for software requirements management level of software requirements quality of software requirements and understanding of quality aspect common problems of requirements elicitation and awareness of impact and damage due to incorrect or low quality requirements. Success factors of software requirements management and 1-10-100 rules are also discussed. Finally the article addresses roles and goals of software requirements management team.

Manpower demand and characteristics of software personnel in Thailand
Manpower demand and characteristics of software personnel in Thailand

The objectives of this research are to study manpower demand characteristics of software personnel and the development trend of software industry. Both quantitative and qualitative approaches are applied by using questionnaire and in-depth interview for data collection. The research sample is 85 software industries. Descriptive and inference statistics are used; frequency percentage arithmetic mean and standard deviation The results showed that many of software personnel in software industry who operate in the position of Programmer/Software Developer/Tester. In the year 2011 and 2012 the software industry require software personnel in the position of Software Engineer and Graphic Designer the most. In addition the required qualification of such software personnel in the year 2011-2015 is the person with bachelor degree and experienced. Features of the software personnel who the software industry recognizes the importance of the top three include knowledge moral and ethics and relations and responsibilities between people. The development trend of software personnel in Thailand are the following: The development of teaching and learning curriculum in cooperation with enterprises and educational institutes teaching and learning process arrangement should be emphasis on practicing part establishing obvious intern plans and cooperative education plans. Also the software personnel should be trained concerning business administration management and presentation. Government sector should encourage the software personnel development in Thailand with regard to education and fund.

A Study value added for increase valued the Anti–insect Cloth Hanger Product Cast Study : Bansaphatana Group Cluster
A Study value added for increase valued the Anti–insect Cloth Hanger Product Cast Study : Bansaphatana Group Cluster

The main objective of this research has to study the production process and the production development of a community business. In the case of Bansaphatana network enterprise study in the part of products form and duty function for increase the product value and response to customer demand by using the application of engineering value plans in seven(7) steps of A.E.Mudge. This in proceeding implementation was beginning from 1) do the data collects and data analyses by prominent point comparison (strength and weakness point of product) the defect of clothes hanger each kind products in each. 2) Use engineering worth technique in 3) analysis’s brainstorm 4) assess for seeking the trend to increase product value of anti-insect cloth hanger. Which the result get from this research has done products development and the procedure produce form as distinctly divided into male and female a way to create product identity and enhance usability duty of the clothes hanger. It could be usage the hang clothes in diverse way such as trousers skirt one stripe blouse etc. It’s build hook product there’s strength durability. From the result’s assessment compares with before and after the conduct of this research found that total investment increased from 15.93 baht to 20.93 baht Which compose the costs of raw materials from 11.93 baht to 14.43 baht and labor capital increases from 4.00 baht to 6.50 baht. While wholesale price increased from 30 baht to 45 baht thus make the profit increases from 9.07 baht to 14.07 baht per piece Can be think the difference profit rate of the products 1 piece be 10.28%.
