Queuing theory is important as a statistical technique for solving problems, analyzing systems, and reducing the adverse effects of waiting. The present research has been done to solve the problem of overcrowding congestion during the distribution of subsidy goods in the Refah chain stores. The purpose of the research is to analyze the queuing system and provide a solution to overcome the crowds in the Refah stores. In this research, a way of providing customer service was reviewed, then customer arrival times, waiting times in queues and customer service were measured. The type of time distribution was followed by Minitab software. Then, the Arena software and the obtained distributions used to simulate the queue system of the store. And the simulation results were used to analyze the queuing system. The results showed that during the distribution of subsidy goods, to fix the queue congestion, 40% of customers should beat the 2nd fund and the rest should equally be divided between the 5th and 6th funds. The implementation of the run-queue system, before the customer enters the funds, is the innovation of this research.

Purpose – The purpose of this paper is to establish an adaptive assembly, to realize the adaptive changing of the models and to improve the flexibility and reliability of assembly change. For a three-dimensional (3D) computer-aided design (CAD) assembly in a changing process, there are two practical problems. One is delivering parameters’ information not smoothly. The other one is to easily destroy an assembly structure. Design/methodology/approach – The paper establishes associated parameters design structure matrix of related parts, and predicts possible propagation paths of the parameters. Based on the predicted path, structured storage is made for the affected parameters, tolerance range and the calculation relations. The study combines structured path information and all constrained assemblies to build the adaptive assembly, proposes an adaptive change algorithm for assembly changing and discusses the extendibility of the adaptive assembly. Findings – The approach would improve the flexibility and reliability of assembly change and be applied to different CAD platform. Practical implications – The examples illustrate the construction and adaptive behavior of the assembly and verify the feasibility and reasonability of the adaptive assembly in practical application. Originality/value – The adaptive assembly model proposed in the paper is an original method to assembly change. And compared with other methods, good results have been obtained.

The queuing theory is the mathematical approach to the analysis of waiting lines in any setting where arrivals rate of the subject is faster than the system can handle. It is applicable to the health care setting where the systems have excess capacity to accommodate random variation. Therefore, the purpose of this study was to determine the waiting, arrival and service times of patients at AAUA Health- setting and to model a suitable queuing system by using simulation technique to validate the model. This study was conducted at AAUA Health- Centre Akungba Akoko. It employed analytical and simulation methods to develop a suitable model. The collection of waiting time for this study was based on the arrival rate and service rate of patients at the Outpatient Centre. The data was calculated and analyzed using Microsoft Excel. Based on the analyzed data, the queuing system of the patient current situation was modelled and simulated using the PYTHON software. The result obtained from the simulation model showed that the mean arrival rate of patients on Friday week1 was lesser than the mean service rate of patients (i.e. 5.33> 5.625 (λ > µ). What this means is that the waiting line would be formed which would increase indefinitely; the service facility would always be busy. The analysis of the entire system of the AAUA health centre showed that queue length increases when the system is very busy. This work therefore evaluated and predicted the system performance of AAUA Health-Centre in terms of service delivery and propose solutions on needed resources to improve the quality of service offered to the patients visiting this health centre.

The scientific - methodological approach to calculation of duration and estimation of complexity of the expertise of technical and operational documentation for measuring equipment and technical devices used in the field of construction and housing sector is suggested. The approach is based on both the theory of queueing systems and probabilistic and statistical methods. The developed approach is implemented in the form of package of applied programs. The software based on complex using the principle of decomposition of object into constituent parts, the queuing theory and the method of expert estimations. The software allows on the basis of the results of statistical data processing for the past periods of work to receive both estimates of the average time of the expertise as a whole, and the estimates of the individual expertise stages. The algorithm for calculating the required number of employees for quality customer service is developed, taking into account the restriction on the waiting time of the request in the queue. The obtained results make it possible to make optimal use of working personnel at various work sites, taking into account their qualifications and training. The developed approach can be used to form a “fair price list” for private clients and enterprises - customers of expertise.

In the training course in descriptive geometry we consider the class of surfaces formed by circles and named "Circular surface. Within this class of surfaces is the so-called kanalowe surface. Under a lie cyclide belong to canalave surfaces, but in the course of descriptive geometry, their formation is not considered. Under a lie cyclide were discovered by Pierre Charles Francois Dyupen in the early nineteenth century and named in his honor. He dyupen was a disciple of Gaspard Monge, like many great scientists in France at that time. Under a lie cyclide usually represented as envelopes of a family of spheres tangent to three given. Under a lie – the only surface whose focal surface degenerates into a line, and all lines of curvature are circles. Particular cases of ticlid cyclide is a torus, and conical and cylindrical surfaces of revolution. The paper discusses the analytical representation of the focal lines for the General case of a job under a lie cyclide. It is analytically proved that the contact line inscribed in cyclide spheres are circles, and degenerate in the focal curve on the surface is a curve of the В учебном курсе начертательной геометрии из- учается класс поверхностей, образованный окруж- ностями и названный «Циклические поверхности» [5; 8; 12].

AbstractOwing to technological advancements in artificial intelligence, voice assistants (VAs) offer speech as a new interaction modality. Compared to text-based interaction, speech is natural and intuitive, which is why companies use VAs in customer service. However, we do not yet know for which kinds of tasks speech is beneficial. Drawing on task-technology fit theory, we present a research model to examine the applicability of VAs to different tasks. To test this model, we conducted a laboratory experiment with 116 participants who had to complete an information search task with a VA or a chatbot. The results show that speech exhibits higher perceived efficiency, lower cognitive effort, higher enjoyment, and higher service satisfaction than text-based interaction. We also find that these effects depend on the task’s goal-directedness. These findings extend task-technology fit theory to customers’ choice of interaction modalities and inform practitioners about the use of VAs for information search tasks.

Queuing Theory is a branch of knowledge in operation research that concerning the analysis of queues when a customer arrives at a service centre and shall queue in a line to get some service. The theory pays attention to how organizations can serve a large number of customers who demand a quality services and a queue of customers waiting to be served. Eventually, the store owners have to attend to large numbers of customers at a time have attempted to measure and manage queues to reduce the customer procession time. Besides, to increase sales and profit, productivity and operation efficiency, satisfaction levels and customer loyalty in using the service provided. In line to the situation, this study is to determine the effectiveness of the waiting line using Queuing Theory at cooperative-mart. Until today, no research conducted about school cooperatives-mart to observe and solve the massive inflow of customers at lines at a given time especially during lunch hour. The purposes of this study are to determine the customer congestion at the payment counter and to propose the effective queuing system at Cooperative-mart. Waiting and services times of customers at cooperative-mart is studied in three times period that to be considered as peak hours in two types of counter which are for male and female.  Data collection was observed by using queuing theory and the M/M/1/∞/∞ queuing model has been implemented.  The results show that for optimum service level, the counter must be changed from one to two counters each side.  The summary and finding of the study shall be used as guideline for the management of cooperative-mart in deciding improvement of its operation.

In this paper, we obtained a spectral expansion of the solution to the Lindley integral equation for a queuing system with a shifted Erlang input flow of customers and a hyper-Erlang distribution of the service time. On its basis, a calculation formula is derived for the average waiting time in the queue for this system in a closed form. As you know, all other characteristics of the queuing system are derivatives of the average waiting time. The resulting calculation formula complements and expands the well-known unfinished formula for the average waiting time in queue in queuing theory for G/G/1 systems. In the theory of queuing, studies of private systems of the G/G/1 type are relevant due to the fact that they are actively used in the modern theory of teletraffic, as well as in the design and modeling of various data transmission systems.

Abstrak�Studi untuk mempelajari perilaku elemen antrian (waktu tunggu nasabah, waktu pelayanan, waktu menganggur teller dan sebagainya) dalam suatu sistem dapat ditinjau dengan teori antrian. Elemen antrian, terutama waktu pelayanan saat transaksi, dapat dijadikan tinjauan dalam meningkatkan kepuasan nasabah. Kecenderungan kesibukan aktivitas pelayanan di bank adalah merata setiap harinya. Kondisi ini berbeda dengan Bank BNI 46 Cabang Universitas Kuningan yang mempunyai antrian yang sangat panjang pada waktu menjelang UAS. Model antrian bank tersebut dianalisis dengan mempertimbangkan distribusi pola kedatangan, distribusi pola pelayanan dan jumlah teller menggunakan �fit test. Hasil uji ini menunjukkan pola kedatangan berdistribusi Poisson dan pola pelayanan berdistribusi eksponensial. Dan karena jumlah teller adalah 1, maka mengikuti notasi Kendall, model antrian bank adalah M/M/1. Simulasi pelayanan transaksi pada bank dilakukan untuk melihat kecenderungan perilaku elemen antrian. Simulasi menunjukkan semakin besar tingkat pelayanan, semakin besar peluang waktu menganggur teller. Akan tetapi, semakin besar tingkat pelayanan, banyak nasabah dalam antrian dan dalam sistem antrian akan semakin sedikit. Demikian juga dengan waktu rata-rata nasabah dalam antrian dan dalam sistem antrian.Kata Kunci: Model Antrian, Perilaku Elemen Antrian, Simulasi.�Abstract�A research to study behavior of queue elements (customer waiting time, service time, idle time teller and so on) in a system can be reviewed with queuing theory. The queue element, especially the transaction time, can be used as a review to improve customer satisfaction. The tendency of busy activity in bank service is evenly distributed every day. This condition is different from BNI 46 Bank branch Kuningan University which has a very long queue at the time before final examination. The bank queue model is analyzed by considering the distribution of arrival pattern, service pattern distribution and number of teller using fit test. The results of this test show the pattern of arrival of Poisson distributed and exponential distribution service pattern. And since the number of tellers is 1, then following Kendall notation, the bank queue model is M / M / 1. Simulation of transaction service at bank is done to see tendency of queue element behavior. Simulations show the greater the level of service, the greater the chance of idle time teller will be. However, the greater the level of service, the more customers in the queue and in the queuing system will be less. Likewise, the average time the customer is in the queue and in the queuing system.�Keywords: Queue Model, Behavior of Element Queue, Simulation.
