Abstract: Competing lies in the heart of every debate and it can be existing for the students who follow the degree programme in specialization of Human Resource Management. In recent years one trend has been to argue that it is necessary to intervene ‘strategically’ in such debates competition. Educators are seeking to develop thinking skills would likely consider their efforts largely successful if students became proficient in advancing, critiquing, and defending claims in reasoned discussion with peers. The proof of a good debate lies in the skills of the debaters to convey their message to present their arguments convincingly and to rebut the arguments of their opponents in a logical and persuasive way. Oral mathematical and logical communication can be used as a tool to communicate effectively in such debating process. Our work is motivated the management undergraduate students by providing strategies to compete debate competition and arguments with proper justification with the connection of mathematical logic reasoning concepts. This research is a qualitative study. Participants selected from final year students of BBM Honours in Human Resource Management undergraduates of Vavuniya Campus who are involving in debate competitions. Data was collected through in-depth interview. The transcribed data was translated into mathematical language based on the theoretical framework of oral mathematical communication. Finally, the study derived an algorithm for the demonstration of debate competition by mathematical logic reasoning.

Abstract: The objectives of the study are to find the optimal solution that minimizes transportation cost by choosing economical route for transportation the pipes for water supply from different stores to the particular sites and to find the efficient route that make optimal transportation schedule in Sri Lanka. The transportation data related to length of pipe required for eleven site locations, availability of pipes at stores, number of truck loads which need to be transported, required truck load for sites and available truck loads at stores and transport cost per truck load were calculated from the national water supply and drainage board report in 2020. The data was modelled as mathematical form using linear programming of transportation type and represented as transportation tableau which was done by Excel Solver to generate its initial basic feasible solution and optimal solution as well as for further improvement like sensitivity analysis in the study. The experimental results show that, the optimum solution of the transportation problem is Rs 79,363/= and at the real situation, number of trucks hired should be an integer value. Based on this aspect, actual minimum total cost for transport is Rs 91,175/=. Further, based on the solver solution material transport arrangement, most cost effective route of transporting materials from national water supply and drainage stores to the relevant sites also were identified. In addition to the above results, sensitivity analysis including reduced cost, allowable increase and decrease in current coefficient and constraints as well as shadow prices also estimated in the study. The findings of the may useful to the managers and engineers who involve on water supply and drainage to provide the effective water distribution systems to the various locations at a minimum transportation cost in the country.

Abstract: This paper presents computational topology techniques for Model Based Enterprise (MBE) focusing on manufacturing as reconstruction of surfaces with boundary, where all shapes of objects considered as assumed to be embedded in R^3. Model based design methodology is applied in mathematical embedded system. The idea exhibited based on the concepts that, topology allows more relaxed ideas of equivalence of shapes than geometry. The method of polygonal representation is used for identifying combinatorial views of the final shape of an object (output design) and its’ base form (input material) where are in a space. While developing this model, we have seen that most of the work with surfaces thought of as objects in space can be used by treating them as certain types of “algebraic” objects. This study finds out that what are the operations can be done by using topological properties in the process of deformation between the final shape and its’ base form. Internal process of the modeling system translates into precise the mathematical language. MBE aims to match the capability of manufacturing system to the outputs required for the manufacturing system by using the above techniques. Some home usage products were considered as sample models. The study is discussed and examples are shown to demonstrate the effectiveness of this approach, with specific demonstration of reconstruction improvements where refined shape optimizations have been crucial. Through these techniques, optimal way of process to the manufacturing can be identified.

Abstract: This study explored the factors affecting the interest of students in learning quantitative technique subjects among the faculty of business studies third and fourth-year students in Vavuniya Campus, Vavuniya, Sri Lanka. A sample of 150 students was selected from two batches which were studied quantitative techniques subjects namely business mathematics, business statistics, computer applications in management and management science applications in their course. The student interests in learning of these subjects are associated with three explanatory variables such as contributions of learning to the major subjects, completing a research work and participating internship programs and the data related to these aspects were collected during the academic year 2016/2017. A structured questionnaire was used to collect the data on students' interests in learning quantitative subjects and the specific factors which influence it in the campus. The collected data were analyzed using Pearson correlation statistic and multiple regression analysis, and the correlation results showed that all three explanatory variables have positively correlated with the students' interest in learning and it is statistically significant at 1% of level. Results of multiple regression model revealed that all the above explanatory variables have positively effect on students’ interest in learning the quantitative techniques subjects and out of them, contributions to complete their research work has more significant in determining the interest on the subjects. This finding may help to the academic staffs who teach these subjects to prepare their session plan with various structural strategies which they can use to teach the students effectively to enhance their interest of learning these subjects in the study area.
