การวิเคราะห์ระบบแถวคอยของการลงทะเบียนวิชาเรียน ของนิสิตบัณฑิตวิทยาลัย จุฬาลงกรณ์มหาวิทยาลัย / บุญมี วัฒนานนท์ = An analysis of waiting line system for registration of Graduate Student of Chulalongkorn University / Boonmee Wattananon
This paper studied the Queue System in Registration by utilizing Simulation Technique. The vacity of Operating Characteristics are identified for example; the Expected Number in Queue, the Expected Time in Queue, the Expected Number in System, Expected Time in System ; and Average [Utilization] etc. The study investigated the method of registration used at present and other methods of registration aiming : (1) To study the change of the number of the registrars (Opportunity of servicing) (2) To identify the change when the step of registration were alternate (there are 9 steps in registration) Furthermore, the efficiency of the method of registration used in the present and the varied method of registration is studied in order to get the appropriate system of registration. The study results that the method of registration in use at present is more efficient than the other methods analysed in the research; To study the efficiency of the system of registration, the V.C. [(cost value)] was taken in to an account as a standard and subsequently the lowest value was found of the present system of registration which is equal to 614.007 bath/hour. Morever, the method now in used provided the following operating characteristics e.g.; 65.28% of the maximum of average utilization of registrars is at the 6th step of the system of registration and 7.48% of the minimum is at the 8th step of the system. The maximum of expected time in queue (Wq) and expected number in queue (Lq) are respectively at the 5th and 6th step of the system (Lq = 0.124:0.112; Wq = 9.596 second, 8.956 second). Also, the average time spent in the system (Ws = 42.804 second) and number of students in system (Ls = 1.854) of the 7th step of the system were found to be much greater than the [others].
