This research aims to optimize the working area by developing various pneumatic devices. Which each have different advantages and disadvantages to
the researchers using Analytic Hierarchy Process (Analytical Hierarchy Process) to assist in the analysis, the decision to opt for a wind-powered device in the world. Since it is a complicated process To reflect the priorities of the criteria and alternatives, which is derived from comparing pairs. And is able to measure the consistency of decisions. By defining the decision criteria form. Areas of work The installation of safety equipment and lifetime. The choice of equipment for the wind to be applied. The study and design, which has three modes: 1 is the duct tank with room air in each work area and the winds common to use 2 is to create a structure to the wind on top and. Type 3 cartridge installed wind wind walk on the floor and take cover normal wind. Then make a decision information from experts. And was involved in evaluating
the application of the theory of decision making by the Analytic Hierarchy (Analytical Hierarchy Process) to optimize the working area. Then gather the decision of the evaluation by experts and those involved in the decision to 3 people found the weight of importance of the criteria used to decide the lifetime of 0.23 percent first. The working area of 0.22 percent safety of 0.21 installed and 0.18 percent and 0.16 percent, respectively, the new diagnostic comparison to weight the importance of criteria and alternatives were ranked No. 1. Type 2 0.40 percent and 3 percent, 0.33 and Type 1 0.27 percent, respectively, so the researchers to design, build and wind systems as 2 is to create a structure to the wind above the work area and cartridge installed. Wind Then prepare the satisfaction of real users will find that 45 percent wind-powered device that has been prepared, it helps to increase the working area. An orderly wind Can be applied to any type of wind instruments. Installed in the right position not obstruct the operation. And the structure of the wind system is secure. Assessor's satisfaction rating is 3.27 - 3.40 which is the level of satisfaction with only the pressure of the wind on the service. A satisfaction rating of 2.58 which is in the level of satisfaction.
