Transportation problem is considered a vitally important aspect that has been studied in a wide range of operations including research domains. As such, it has been used in simulation of several real life problems. The transportation model is for the optimization of routes, cost and travelling of peoples with the help of public transport buses from the source to the destination by road. The data is collected which includes number of trips per day, cost of trips per trip ,distance between source and destination etc. manually through the questionery interview with the conductors drivers and the regular travelling peoples travelling on that route as well as data collection from PMPML office and calculation for minimizing the transportation cost have been done. The result of the research with proper scheduling, proper routing of buses can save Rs. 48865.875 in a 1 day. The saving of the transportation cost increases the profit of the PMPML. The total saving amount profit percentage is about 18.15% increase from saving transportation cost. The parameters as discussed above are considered and collected manually with the help of survey sheet and transportation model is prepared and after that calculation for minimizing the transportation cost have been done. The methods used for minimization of transportation of cost are Northwest corner method, Least count method etc. The result of the research gives with proper scheduling, routing of buses can save generate so much of revenue with saving of cost.. The amount saved from the transportation cost is utilized for increase the facilities in bus such as A.C, Automatic door system, Air suspension, Good quality of seats etc.

Cost Of Transportation

For twenty decades, there is a visible ever forward advancement in the technology of mobility, vehicles and transportation system in general. However, there is no "cure-all" remedy ideal enough to solve all life problems but mathematics has proven that if the problem can be determined, it is most likely solvable. New methods and applications will keep coming to making sure that life problems will be solved faster and easier. This study is to adopt a mathematical transportation problem in the Coca-Cola company aiming to help the logistics department manager of the Asejire and Ikeja plant to decide on how to distribute demand by the customers and at the same time, minimize the cost of transportation. Here, different algorithms are used and compared to generate an optimal solution, namely; North West Corner Method (NWC), Least Cost Method (LCM) and Vogel’s Approximation Method (VAM). The transportation model type in this work is the Linear Programming as the problems are represented in tables and results are compared with the result obtained on Maple 18 software. The study shows various ways in which the initial basic feasible solutions to the problem can be obtained where the best method that saves the highest percentage of transportation cost with for this problem is the NWC. The NWC produces the optimal transportation cost which is 517,040 units.

Some of industrial and real life problems are difficult to be solved by traditional methods, because they need exponential number of calculations. As an example, we can mention decision-making problems. They can be defined as optimization problems. Ant Colony Optimization (ACO) is between the best methods, that solves combinatorial optimization problems. The method mimics behavior of the ants in the nature, when they look for a food. One of the algorithm parameters is called pheromone, and it is updated every iteration according quality of the achieved solutions. The intuitionistic fuzzy (propositional) logic was introduced as an extension of Zadeh’s fuzzy logic. In it, each proposition is estimated by two values: degree of validity and degree of non-validity. In this paper, we propose two variants of intuitionistic fuzzy pheromone updating. We apply our ideas on Multiple-Constraint Knapsack Problem (MKP) and compare achieved results with traditional ACO.

Real Life Situation

Most of the problems arise in real-life situation are complex natured. The level of the complexity increases due to the presence of highly non-linear constraints and increased number of decision variables. Finding the global solution for such complex problems is a greater challenge to the researchers. Fortunately, most of the time, bio-inspired techniques at least provide some near optimal solution, where the traditional methods become even completely handicapped. In this chapter, the behavioral study of a fly namely ‘Drosophila' has been presented. It is worth noting that, Drosophila uses it optimized behavior, particularly, when searches its food in the nature. Its behavior is modeled in to optimization and software is designed called Drosophila Food Search Optimization (DFO).The performance, DFO has been used to solve a wide range of both unconstrained and constrained benchmark function along with some of the real life problems. It is observed from the numerical results and analysis that DFO outperform the state of the art evolutionary techniques with faster convergence rate.

The Impact

Geometric instabilities in bilayered structures control the surface morphology in a wide range of biological and technical systems. Depending on the application, different mechanisms induce compressive stresses in the bilayer. However, the impact of the chosen origin of compression on the critical conditions, post-buckling evolution and higher-order pattern selection remains insufficiently understood. Here, we conduct a numerical study on a finite-element set-up and systematically vary well-known factors contributing to pattern selection under the four main origins of compression: film growth, substrate shrinkage and whole-domain compression with and without pre-stretch. We find that the origin of compression determines the substrate stretch state at the primary instability point and thus significantly affects the critical buckling conditions. Similarly, it leads to different post-buckling evolutions and secondary instability patterns when the load further increases. Our results emphasize that future phase diagrams of geometric instabilities should incorporate not only the film thickness but also the origin of compression. Thoroughly understanding the influence of the origin of compression on geometric instabilities is crucial to solving real-life problems such as the engineering of smart surfaces or the diagnosis of neuronal disorders, which typically involve temporally or spatially combined origins of compression.

The Many

The continuous increases in the size of current telecommunication infrastructures have led to the many challenges that existing algorithms face in underlying optimization. The unrealistic assumptions and low efficiency of the traditional algorithms make them unable to solve large real-life problems at reasonable times.The use of approximate optimization techniques, such as adaptive metaheuristic algorithms, has become more prevalent in a diverse research area. In this paper, we proposed the use of a self-adaptive differential evolution (jDE) algorithm to solve the radio network planning (RNP) problem in the context of the upcoming generation 5G. The experimental results prove the jDE with best vector mutation surpassed the other metaheuristic variants, such as DE/rand/1 and classical GA, in term of deployment cost, coverage rate and quality of service (QoS).

The West Lombok Mathematics’ Teacher Community needs to be improved because of the government's demands on the quality of teaching mathematics in schools. Having good mathematical knowledge and being able to solve real-life problems is an important key for teachers to be able to develop innovative mathematics teaching. But in fact, teacher training that emphasizes aspects of mathematical content is still not widely implemented. This is an important reason for this training. The training is carried out in one day through video screening and rich task modeling. The assessment of this training is measured using a closed questionnaire that asks the teacher's attitude towards statements related to the training material, training methods, the ability of the speakers, and the motivation of the trainees. The training that was carried out succeeded in getting a positive response that most of the teachers gave a very agreeing attitude. The teachers also feel motivated and have good expectations for applying the knowledge and skills gained from training into teaching mathematics in the classroom

Low enrollment and high attrition rates in science, technology, engineering, and math (STEM) based degree programs have created a shortage of workforce in industries such as shipbuilding and repair that are important for national security. Part of this problem can be attributed to pedagogical issues such as lack of engaging hands-on activities used for math and science instruction in middle and high schools. Another reason for this is that the teachers are not trained in taking an integrated approach to teaching math and science. This has led to large-scale flight and attrition from STEM-based career tracks. Consequently, engineering and engineering technology programs throughout the nation have observed declining graduation rates and quality of incoming students. To engage students' interest in STEM-based careers, it is important that students establish a link between the math and science instruction and its application to solve real-life problems early in their learning experience. Project-based activities have a proven record as a pedagogical method. Effectiveness of this pedagogy has been supported by research in the acquisition and retention of knowledge. The MarineTech Project funded by the State Council of Higher Education of Virginia and supported by the shipbuilding and repair industry has attempted to address the quality of STEM education in Virginia by developing project-based learning kits and providing professional development training in the use of these kits. The project also provided teacher training in 21st century skills and integrated math and science education while increasing awareness of teachers about the shipbuilding and repair industry. The paper presents the motivation behind developing these project-based learning (PBL) modules, issues related to implementation, and results from student and teacher workshops.

PurposeThis study explores how the implementation of problem-based learning (PBL) in technical and vocational education training (TVET) systems of Nigerian higher education (HE) can enhance quality graduate outcomes. The study also explores the issues and challenges of PBL implementation in the TVET system of Nigerian HE.Design/methodology/approachThis study follows the assumptions of qualitative research. The authors interviewed 55 participants and had a focus group with 7 TVET postgraduate students. The 55 interviewees were drawn from TVET teachers (n = 33; 24 males and 9 females), Directors at National Board for Technical Education (n = 4; 3 males and 1 female), Directors of National Directorate of Employment (n = 5; 3 males and 2 females), Directors at the Federal Ministry of Education (n = 3 males), and industry executives (n = 10; 7 males and 3 females). Data were collected through a semistructured interview approach, transcribed and coded using NVivo 12 plus and analyzed through thematic analysis.FindingsThe results show that PBL in the Nigerian TVET system has positive implications for quality TVET graduate outcomes in that it can enable integrating theory and practice, motivate learning, improve students' self-efficacy, allow students to construct learning on their own, enhance graduate competencies and graduate employability. It also revealed six perceived possible major challenges to effective implementation of PBL in the Nigerian TVET system, which includes inadequacy of teaching and learning facilities; corruption in Nigerian education sector; recruitment of unqualified incompetent TVET teachers; difficulties in identifying real-life problems, among others. Participants offered benchmarks and actions and standards for improving the identified challenges, which formed a framework for coping with issues, challenges, and barriers to effective implementation of PBL in the TVET system of Nigerian HE (Table 1).Originality/valueThe results of this study are original and serve as an advocacy for Nigerian HE authorities to explore how PBL can be implemented in the TVET system to improve graduate outcomes. The study serves as a starting point for more research in the domain of improving the quality of TVET programs in Nigerian HE. Industry leaders and policymakers in Nigeria and other developing countries could use the findings from this study to increase HE and industry participation and partnership for quality of TVET program.
