Using Markov Chain to Analyze Production Lines Systems with Layout Constraints [PDF]

open access: yesJournal of Optimization in Industrial Engineering, 2010
There are some problems with estimating the time required for the manufacturing process of products, especially when there is a variable serving time, like control stage. These problems will cause overestimation of process time.

A Two‐Stage Queue Model to Optimize Layout of Urban Drainage System considering Extreme Rainstorms [PDF]

open access: yesMathematical Problems in Engineering, 2017
Extreme rainstorm is a main factor to cause urban floods when urban drainage system cannot discharge stormwater successfully. This paper investigates distribution feature of rainstorms and draining process of urban drainage systems and uses a two‐stage single‐counter queue method M/M/1 → M/D/1 to model urban drainage system.

Queue Layouts of Planar 3-Trees [PDF]

open access: yesAlgorithmica, 2018
AbstractA queue layout of a graph G consists of a linear order of the vertices of G and a partition of the edges of G into queues, so that no two independent edges of the same queue are nested. The queue number of graph G is defined as the minimum number of queues required by any queue layout of G.

Queue Layouts of Graphs with Bounded Degree and Bounded Genus [PDF]

open access: yesCoRR, 2019
Motivated by the question of whether planar graphs have bounded queue-number, we prove that planar graphs with maximum degree $Δ$ have queue-number $O(Δ^{2})$, which improves upon the best previous bound of $O(Δ^6)$. More generally, we prove that graphs with bounded degree and bounded Euler genus have bounded queue-number.

Stack and Queue Layouts via Layered Separators [PDF]

open access: yesJournal of Graph Algorithms and Applications, 2016
It is known that every proper minor-closed class of graphs has bounded stack-number (a.k.a. book thickness and page number). While this includes notable graph families such as planar graphs and graphs of bounded genus, many other graph families are not closed under taking minors.
