SCOPE OF PUBLICATION Matematika is an open access, peer-reviewed journal that considers articles bearing manifestation of new ideas and original research across a range of mathematical science topics. It is an interdisciplinary journal containing research articles that treat scientific and industrial problems using techniques that are of mathematical interest. The journal publishes novel applications in all areas of industrial and applied mathematics including engineering, physics, chemistry, biology, ecology, economics, mathematical finance, mathematical biosciences, medical, information theory and more. Mathematical techniques of interests include asymptotic methods, control theory, bifurcation theory, dynamical systems theory, computational methods, numerical analysis, optimization, operational research, probabilistic and statistical methods. Articles on algebra and analysis related to scientific and industrial problems are also welcome. Matematika is published online with a frequency of two issues per year (June and December). Besides that, special issues of Matematika will be published non-periodically from time to time.

It was initiated and managed by (formerly known as UTM Department of Mathematics) until 2013. It started as a platform for researchers to present high-level mathematical research within the local community but has since evolved to attract growing international readership. In 2014, the journal underwent a substantial relaunch and restructure, which includes online submission features under the administration of UTM Centre for Industrial and Applied Mathematics (). PREFACE This special issue of MATEMATIKA: Malaysian Journal of Industrial and Applied Mathematics 2018, publishes seventeen selected papers which were being carefully reviewed. These papers were originally presented at the International Seminar on Mathematics in Industry & International Conference on Theoretical and Applied Statistics 2018 (ISMI-ICTAS 2018), which was held at UTM Kuala Lumpur, Malaysia from Sept 4 until Sept 6, 2018. This issue covers a range of industrial mathematics and statistics with their applications in various industries which include Health, Biotechnology, Finance & Economics, Oil & Gas Refinery, Logistics, Hydrology, Environment and Insurance.
