Malaysian Mathematics In Industry Workshop (MMIW2018), is a special engagement session with industry practitioners/researchers where participants are given the opportunity to work on industrial problems shared  by industries using diverse mathematical approaches.

The participants will then work with the industry practitioners/researchers to formulate the problems using mathematical or statistical models. At the end of the session, the participants and the industries representatives will collaboratively outline possible future work that can be done in solving the problem.

This workshop provides an opportunity for academics and industrial researchers/practitioners to network, exchange ideas, solve industrial problems, and identify future strategic collaboration.

We proudly present the three industrial problems for our MMIW2018

Industrial Problem 1

Telemong River Bifurcation for Flood Mitigation

Telemong River catchment in Terengganu is prone to flooding. Extensive flooding throughout the catchment occurs during heavy and prolonged rainfall resulting into high river flow. The river will overspill the banks of Telemong River on the east side disrupting road networks and human life. In addition, due to the flat nature of the topography, the flood will move in an easterly direction and slips into Cepuh River catchment and thus cause flooding in that area. Apart from deepening and widening of the rivers to mitigate flood, main mitigation action is to divert some of Telemong River’s flow during peak flow to Cepuh River by extending Cepuh River at its upstream end to join Talor River, a subsidiary river of Telemong River. The situation of the river will change, from a single Telemong River bifurcated into two. The question is to quantify the amount of flow from a single Telemong River to the two new outlets, which are the new Cepuh River route and also the original Telemong River. The amount of flow rate going through these two outlets of the bifurcated river is important in order to mitigate flood. The bifurcation junction has been designed; such as the cross section of Cepuh River and the angle between Cepuh River and Telemong River, in accordance to the restrictions of the location’s topography and properties such as private lands, existing bridges and other hydraulic structures. Given the peak flowrate, cross sections of Telemong River before and after the bifurcation junction and Cepuh River, and also the angle between Cepuh River and Telemong River, it is important to justify the amount of flowrate entering Cepuh River so that both Cepuh River and Telemong River are still able to convey water during peak flow.

Industrial Problem 2

Time versus Gain Analysis for Crude Palm Oil Trading

Algorithmic Trading (AT) has been employed by most of the market participants in order to make an automatic trading decision. Generally, AT which is also known as a computer algorithm works as an effective and efficient tool in analysing the financial big data. However, there are several concerns involved in maximising the gain from the trade. First, due to extremely volatile Crude Palm Oil (CPO) prices in a very short period of times, challenges emerge in trading the CPO stock prices since the future of CPO stock movement will be hard to be determined. Second, another new extension of AT is needed to be proposed in order to make an accurate decision on the length of frequency returns. In other words, it is the short-term trading which is more profitable as compared to the long-term trading? To solve these issues, a new technical indicator that is able to adapt volatility and automatically determine the duration of trading need to be performed in order to optimize the CPO stock price profit.

Industrial Problem 3

Cable Installation Analysis in Deep Water Environment

Deep water telecommunication/power cable installation starts at water depth of 300m and more, where the cable will be facing high stress force from its own weight, under-water current and also the swell on seabed surface, leading to a large number of cyclic loads in terms of tensile and bending. In more complex scenario, the forces may also include interaction of the cable with other cables during installation, and also the use of necessary floatation structures attached to the cable. Since the reliability performance of these cables is very crucial, the mechanical operation of this submarine cable for seabed deployment is mainly determined by the axial strength, and thus there is a need to investigate the relationship between internal and external forces and the stress localisation in the cable. This includes the determination of appropriate locations for the float, and suggestions on how to effectively mitigate the negative impacts that might reduce its lifetime design and maintenance to the cable system.

There are two types of termination ends; i.e. free rotating end (single point mooring) and fixed end (multiple point mooring).  We will be focusing on the single point mooring since it is the fundamental of all deep-water installation (costly).  Study shows that for fixed end mooring, the response to the axial load will be directly related to the strain.  Calculation of the local stress on the cable individual elements involves finite element analysis.  This is to determine the distribution of stress with in the cable construction, hence to evaluate load combination to avoid the stress to reach critical failure state.

One of the external forces that will affect the cable dynamical analysis is the floatation structure that needs to be attached to the cable.

We would like to concentrate on the stress localisation of the cable.  Where is the point that the float can be put to mitigate the built-up stress to the cable?
