this paper presents a new nonlinear mathematical model to solve a cell formation problem which assumes that processing time and inter-arrival time of parts are random variables. in this research, cells are defined as a queue system which will be optimized via queuing theory. in this queue system, each machine is assumed as a server and each part as a customer. the grouping of machines and parts...

Mobile ad-hoc networks pose real difficulty in finding the multihop shortest paths because of continuous changing positions of the nodes. Traditional ad-hoc routing protocols are proposed to find multi-hop routes based on shortest path routing algorithms, which cannot effectively adapt to time-varying radio links and network topologies of Ad-hoc networks. In this paper we proposed an enhanced r...

Design: We used a queuing theory model to simulate 3 different potential solutions to decrease the delay from patient identification to connection with discharge services. Measurements: The measures included average rate at which patients were being connected to the post discharge heart failure services program, average number of patients in line, and average patient waiting time. Results: Usin...

To operate a multiple product manufacturing system under a CONWIP control policy, one must decide how to assign kanbans to products. With a fixed total number of kanbans in a competitive environment, the goal is to determine their allocation to product types in order to minimize lost sales equitably. In particular, we consider systems in which the products may make multiple visits to the same s...

This paper studies the traffic allocation in multi-path routing in consideration of the strict requirement for delay variation in the real-time applications. Firstly, the queuing delay is analyzed based on network calculus and the upper bounds of end-to-end delay and its variation in all paths are deduced. Then the transfer rate of data flowing into each path should be used as constraint for sa...

Process-driven spreadsheet queuing simulation is a better vehicle for understanding queue behavior than queuing theory or dedicated simulation software. Spreadsheet queuing simulation has many pedagogical benefits in a business school end-user modeling course, including developing students' intuition , giving them experience with active modeling skills, and providing access to tools. Spreadshee...

Traditional resources allocation in port usually use queuing model and has deviations between model and actual situation. In this paper, focus on loadometers allocation in bulk port, we propose an optimization solution with Internet of Things. Primary method of this solution is upgrading devices with RFID technology. This solution provides more efficiencies and accuracies cause of reducing manu...

Most existing organizational design processes focus on either the qualitative or domain-independent features of candidate designs. This paper demonstrates the significance of domain-specific features through an examination of an organizationally-driven information retrieval network. The behavior of a search process for appropriate agents and the consequences of hierarchical control in a continu...
