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.

Densification of rice straw such as compacting and pelletizing is an important process to increase the density of rice straw resulting in a reduction of transportation cost. Within this research, we conducted a techno-economic investigation of rice straw densification to produce compressed bales and pellets, which are later used for animal feed. In line with the main deliverable of the performance of rice straw compacting and pelletizing processes, we also looked into the quality of the product in terms of uptake and digestibility of the cattle feed which could be improved by adding amendments such as urea during the compacting process. The compacting technology resulted in a 400% increase of bale density (from 94 to 390 kg.m-3). This could reduce transportation costs by about 60% for a 60 km driving distance using trucks. The net profit that resulted from compacted bales was USD 0.0062 kg-1. Although the pelletizing technology increased the cost of the densified product by 40–50%, its density increases by 700%, from 94 to 666 kg.m-3. The enriched-rice straw pellets contained 12.1% protein, 2.8% lipid, 32.7% raw fibre, and 11.2% ash. In addition, a test of this product for cattle feeding illustrated an increase in its eating desirability for cows. Findings from this study contribute to reducing feedstock cost and developing densified rice straw products. These, therefore, provide more alternative options to increase the benefits from rice production and thus, reduce the unsustainable burning of rice straw in the field.

AbstractDistribution of products from the company's warehouse PT. MMM to consumers so far the company only uses estimates of consumers which will be passed in one shipment only by looking at the number of requests without considering the shipping routes and distance from the warehouse to the location of the consumer. This study aims to determine an effective shipping route using the saving matrix and nearest neighbor methods then find out distance savings and transportation cost savings. Comparison of the product distribution routes of PT. MMM after using the saving matrix method and the nearest neighbor method results in an effective and efficient route where the initial distribution route is 40 routes into 7 routes for 7 days of product distribution to consumers. The saving matrix method is applied. shows a reduction in the distance of the original shipment of 1,673.6 Km to 810.7 Km, thus obtained a savings of a distance of 862.9 Km. As well as a significant reduction in transportation costs where the initial cost of transportation of Rp. 4,478,448.- dropped to Rp. 3,675,951.-, so the company can save on transportation costs by Rp. 802,497.-.AbstrakRute pendistribusian produk dari gudang perusahaan PT.

The passage of landmark deregulatory reforms in the Motor Carrier of Act of 1980 has constantly pressured the U.S. trucking industry to reduce transportation costs. Thanks to such pressure, total logistics costs have declined from 16.5% in 1980 to 10.1% of gross domestic product (GDP) in 2000. In particular, transportation costs have fallen from 7.6% to 5.9% of GDP in 2000. Transportation cost savings definitely benefit shippers, while jeopardizing the viability of carriers. To help transportation carriers cope with enormous cost pressure, this paper examines the impact that “lumper” costs, empty miles, and shipment size have on the very competitive trucking industry. Through an actual case study of a firm based in the Southeast U.S., we illustrate how lumper costs, empty front-haul and backhaul, and shipping weight and pieces can adversely affect the trucking firm’s profitability.

Consumer demand for consistently high quality meats has exposed a series of problems in the Brazilian frozen beef agro-industrial logistics chain arising from a lack of adequate infrastructure to cope with export flows. Based on interviews with the sector’s agents and on a comparative analysis of transportation costs, this paper aims to identify and evaluate infrastructure bottlenecks that affect the Brazilian frozen beef logistics chain and the economic gains that could be achieved by directing more frozen beef exports through the country’s Northern Arc ports. Among the results obtained from analyzes of frozen beef export flows from the state of Mato Grosso, the Brazilian state with the greatest number of plants that process beef for export, the use of Northern Arc ports can bring road transportation cost savings of up to 43% for some localities. It was also found that the lack of maritime shipping capacity, whether from restricted port capacity or infrequent ship departures, is one of the main logistical problems impeding the flow of frozen beef from ports inBrazil’s north.

The factors contributing to the line haul transportation costs of very large trucks operating on the Ontario highway system are calculated from fundamental tractive resistance equations and tractive effort characteristics for two "weigh-out" commodity types and representative haul routes. These calculated costs are compared with some observed costs and earlier analyses to check the validity of the models. The theoretical models are then used to assess the impact on operating costs of a variety of truck parameters which include truck type and tire pressures. The pavement damage created by the different truck types are estimated and the damage costs compared with the savings in line haul transportation costs. It is concluded that the pavement damage impacts of different truck types should be carefully compared with potential line haul transportation cost savings to ensure that allowable truck configurations are economically efficient with respect to both public and private costs. Key words: highway engineering, pavement damage, pavement cost, truck operating cost, vehicle weights.

Palm oil is rich in carotenoids and the major component of its glycerides is the saturated fatty acid palmitic. Because of its economic importance as high-yielding source of edible and technical oils, the oil palm is now grown as a plantation crop in most countries with high rainfall in tropical climates within 10 of the equator. The individual fruit ranging from 6 to 20 gm, are made up of an outer skin (the exocape), a pulp (mesocarp) containing the palm oil in a fibrous matrix; a central nut consisting of a shell (endocarp); and the kernel, which itself contains an oil, quite different to palm oil, resembling coconut oil (Poku, 2002). Nowaday in Thailand there is no small-scale suitable machine for farmers to separate palm mesocarp from palm nut. This research aims to develop a machine to separate palm fruit mesocarp to yield palm oil of better quality. The machine has four units, namely a mechanical power unit, feed unit, mesocarp milling unit, and discharge unit. The vital part is the mesocarp milling disc, which is the main report of this paper. There are three types of discs according to the surface typography under this study: 1) a disk with small holes and rectangular steel bars on the disk surface; 2) a disk with small holes, each with 1.2 centimeter diameter; 3) a disk with small holes and small steel items on the disk surface. It was found that the highest yield was obtained from the disk with small steel items and can separate mesocarp cleanly from the palm fruit.

The present study examines the effect of agency-level implementation variation on the cost-effectiveness of an evidence-based parent training program (Positive Parenting Program: “Triple P”). Staff from six community-based agencies participated in a five-day training to prepare them to deliver a 12-week Triple P parent training group to caregivers. Prior to the training, administrators and staff from four of the agencies completed a site readiness process intended to prepare them for the implementation demands of successfully delivering the group, while the other two agencies did not complete the process. Following the delivery of each agency’s first Triple P group, the graduation rate and average cost per class graduate were calculated. The average cost-per-graduate was over seven times higher for the two agencies that had not completed the readiness process than for the four completing agencies ($7,811 vs. $1,052). The contrast in costs was due to high participant attrition in the Triple P groups delivered by the two agencies that did not complete the readiness process. The odds of Triple P participants graduating were 12.2 times greater for those in groups run by sites that had completed the readiness process. This differential attrition was not accounted for by between-group differences in participant characteristics at pretest. While the natural design of this study limits the ability to empirically test all alternative explanations, these findings indicate a striking cost savings for sites completing the readiness process and support the thoughtful application of readiness procedures in the early stages of an implementation initiative.
