The purpose of this study is to optimize costs by analyzing a case study of the Energy Utility Company (EUC) project in Malaysia and building the main electric distribution station (MEDS) project specifically. In order to achieve this objective, Value Engineering (VE) technique as one of the proven tools was selected, and three alternatives were applied. The first alternative was to reduce the room sizes of the building. The second alternative was to replace the plaster painting with normal painting, and the last one was to replace painting up to 1.5 meters with 1 meter of the high of walls from the floor. Results approved that the implementation of VE has successfully reduced the cost of the project without compromising the quality of the materials. For the first alternative, 17.1% of the cost was saved. Regarding the second alternative, 69.8% of the total cost for ceiling painting was saved, and for the third alternative, 41.6% of the total cost of walls from the floor was saved. The findings of this research may serve as a guide for engineers, scholars, and constructors to reduce the cost of the building project.

Lot Sizes

Remanufacturing processes face uncertainty in the quality of the items being returned by customers, this significant variability complicates the control of inventories. Demands can be satisfied by procured new items, but also by remanufactured returned items. This paper develops dynamic lot sizing model for remanufacturing industry under uncertainty of returned items and proposes Bayesian Inference to estimate the replacement ratio of returned items that used to determine those lot sizes for new items. The objective of this paper is to minimize the total cost composed of holding cost and set-ups cost. A numerical example is provided based on case study. The result shows that total cost is reduced to be 45%.

Radio Planning

Transitioning a Terrestrial Trunked Radio (TETRA) network to a Long-Term Evolution (LTE) network in public protection and disaster relief (PPDR) systems is a path to providing future services requiring high radio interface throughput and allowing broadband PPDR (BB-PPDR) radio communications. Users of TETRA networks are currently considering how to deploy a BB-PPDR network in the coming years. This study offers several radio planning considerations in TETRA to LTE migration for such networks. The conclusions are obtained from a case study in which both measurements and radioelectric coverage simulations were carried out for the real scenario of the Murcia Region, Spain, for both TETRA and LTE systems. The proposed considerations can help PPDR agencies efficiently estimate the cost of converting a TETRA network to an LTE network. Uniquely in this study, the total area is divided into geographical areas of interest that are defined as administrative divisions (region, municipal areas, etc.). The analysis was carried out using a radio planning tool based on a geographic information system and the measurements have been used to tune the propagation models. According to the real scenario considered, the number of sites needed in the LTE network—for a specific quality of service (90% for the whole region and 85% for municipal areas)—is a factor of 2.4 higher than for TETRA network.

OBJECTIVE Identify the direct cost of reprocessing double and single cotton-woven drapes of the surgical LAP package. METHOD A quantitative, exploratory and descriptive case study, performed at a teaching hospital. The direct cost of reprocessing cotton-woven surgical drapes was calculated by multiplying the time spent by professionals involved in reprocessing the unit with the direct cost of labor, adding to the cost of materials. The Brazilian currency (R$) originally used for the calculations was converted to US currency at the rate of US$0.42/R$. RESULTS The average total cost for surgical LAP package was US$9.72, with the predominance being in the cost of materials (US$8.70 or 89.65%). It is noteworthy that the average total cost of materials was mostly impacted by the cost of the cotton-woven drapes (US$7.99 or 91.90%). CONCLUSION The knowledge gained will subsidize discussions about replacing reusable cotton-woven surgical drapes for disposable ones, favoring arguments regarding the advantages and disadvantages of this possibility considering human resources, materials, as well as structural, environmental and financial resources.

Seismic Images

Seismic acquisition has undergone a revolution over the last few decades. The volume of data acquired has increased exponentially, and the quality of seismic images obtained has improved tremendously. While the total cost of acquiring a seismic survey has increased, the cost per trace has dropped precipitously. Land surveys have evolved from sparse 2D lines acquired with a few dozen receivers to densely sampled 3D multiazimuth surveys. Marine surveys that once may have consisted of a small boat pulling a single cable have evolved to large streamer vessels pulling multiple cables and air-gun arrays and to ocean-bottom detectors that require significant fleets to place the detectors, shoot the sources, and provide support. These surveys collect data that are wide azimuth and typically fairly well sampled.

Significant Regional Difference

In order to develop realistic water resources strategy, we initially analyze the situation of water resources in the United States which present a significant regional difference. Then on the basis of previous studies, we propose the cost formulas of water storage, movement and desalinization. By analyzing the practical application, along with pros and cons of the above three solutions accordingly, we consider that a comprehensive utilization of these measures will be the best water strategy for America to solve the water shortage problem. Later we apply the conclusion to a case study of Southern California, we propose an optimization model which aims to minimize the total cost of the water strategy, and then use Lingo to solve the problem. Results show that 5.946 billion cubic meters of water by transferring is the best way to make up for the water use gap in 2025 and the total cost is 2.94 billion dollars. Finally, we summarize the strengths and weaknesses of our paper. What needs to be emphasized is that our model can also be adapted into the analysis of other states, which shows great flexibility.

Museum Practice

<p>In the current economic climate museums are increasingly being asked to do more with less. For museums that hold collections, this poses a unique challenge. With the cost of collections being relentlessly accumulative, questions are being raised about the long term financial sustainability of current collecting practices. Deaccessioning is being suggested as a way in which museums can improve the quality of their collection without increasing its size. Yet the literature on deaccessioning suggests that the process is fraught with ethical and practical difficulties. By highlighting the negatives aspects of the process, writing in museum studies and practice does little to explore how deaccessioning might be used to achieve positive outcomes. This research addresses this gap by asking whether deaccessioning is a positive tool that, if used appropriately, can assist a museum in improving the quality and manageability of their collection through systematic planning. To understand how and why a museum may permanently remove objects from their collection, the study focuses on one New Zealand museum’s response to the challenge of redeveloping a collection through the process of deaccessioning and disposal. The Museum of Wellington City and Sea’s deaccessioning process is analysed through documentary research and interviews with Museum staff. The interviews offer an understanding of the thought processes and motivations involved in selecting objects to be deaccessioned. The data collected reveals both the challenging aspects of the process but also offers insights into how these aspects can be mitigated or resolved. The conclusions presented in this dissertation suggest that deaccessioning is an integral part of current museum practice that can be used positively to actively shape and refine a museum collection. I argue that some of the beneficial outcomes of the process include greater understanding of collections, improved knowledge and context, resolution of historical collecting problems, strategic relationships built with other museums and improvement in how objects are stored and utilised. More importantly deaccessioning allows museums to determine the character and content of their collections. In order for this to be achieved, I recommend that museums adopt a rational approach to reviewing their collections that is multi-disciplinary, transparent and acknowledges how their collection is used in the achievement of their institution’s mission.</p>

This study aims to determine how the effect of calculating the cost of an order made by the company and the method of calculation of full costing of the product selling price fixing mold. The data used is primary data, order data produced in the period from January 2013 to December 2013, the secondary data obtained from interviews and literature. From these results it can be seen that CV. Sagita Grafika calculate the cost of the product by using the order cost method that produces cost price and the selling price that is incompatible with existing theory, in which the charging of indirect labor and overhead costs shared equally on all types of orders in the amount of Rp. 11.78825 million for indirect labor costs and Rp. 3.1243 million for overhead costs so that volume orders will bear fewer overhead costs equal to the volume of orders more. By using a full costing analysis generated calculation method that the volume of orders that more will earn imposition overhead costs more, because in this calculation loading overhead costs charged by direct labor hours incurred for each order. So that orders with a total volume that many will use a lot of labor hours and vice versa. So in this study that most large orders received charging overhead is the order BS-02 Rp. 31,115,590.92 and most orders received little overhead loading is KK-01 orders in the amount of Rp. 2,208,622.32. Results of a comparison between the cost of the company with the full costing is the total cost of less Rp. 27,499,540.57, the selling price of Rp. 5,866,543.90, while the larger profit generated by using the full costing method that is Rp. 21,632,996.67

This research aimed to study the cost potential of shallot in Rasi Salai District, Sisaket Province in order to lead to planning on pricing, marketing, improving the quality of shallot and analyzing data of farmers and shallot production. The research findings on the general information of shallot farmers revealed that they consisted of 75% of males and 25% of females with 40-49 years of age or 50%. Most of their educational levels were 55% of primary level or lower. They grew shallot together with other crops. The Bang Chang varieties (local shallot varieties of Sisaket Province) were grown most of 75% and the other 25% of local northern verities called Hom Bua. The 70% of planting shallots were harvested from the last season and the other 30% were purchased from other farmers in the market.  The shallot productivity per rai was uncertain depending on the caring, fertilizing and disturbing disease. Approximately 35% of the farmers harvested 1,200-1,500 kilograms per rai or 25%. Regarding the production cost of shallot, it was found that the average mount was 8,151.5 baht per rai with the highest amount of verities of 3,250 baht per rai or 15.2%. The cost of insecticide was 1,000 baht or 10.2% of the total cost. In addition, the least cost was transportation for 3.3% only because most merchants bought shallots at the farming sites.  According to sale data, 70% of the farmers sold local verieties of Sisaket Province with average price of 30 baht per kilogram, followed by 15% of Hom Bua with an average price of 45 baht per kilogram. The average income earned by farmers in each household was different at 20,001-25,000 baht per rai

Cost Components

IntroductionEconomic models contain several parameters ordinarily subject to uncertainty. Unlike most other model parameters, costs can constitute numerous distinct components. For example, a surgical intervention can require a variety of disposables and reusable equipment. A micro-costing output may be disaggregated or presented as a total cost. Uncertainty could be applied to individual cost components or to total cost. We aimed to explore how disaggregation of cost data may impact on uncertainty using a case study.MethodsA set of simulations using hypothetical scenarios were developed with uncertainty set at ± 20 percent. The simulations investigated the impact of number of cost components, balance between components, and correlation between them. A cost-utility model from an assessment of robot-assisted radical prostatectomy was analyzed; procedure cost was divided into 32 individual cost components or treated as a total cost.ResultsBased on five equal cost components, uncertainty reduces from ± 20 percent for correlated variables to ± 9 percent for uncorrelated variables. With increasing numbers of uncorrelated cost components, the uncertainty in the total cost decreases markedly. The uncertainty around total robot-assisted surgery procedure equipment costs was ± 19.7 percent when components were correlated and ± 9.4 percent when uncorrelated. The impact on uncertainty in the incremental cost effectiveness ratio (ICER) was negligible but the ranking of parameters in the univariate sensitivity analysis changed.ConclusionsAnalyzing uncertainty by aggregated or disaggregated costs can have implications for presenting uncertainty in costs to decision makers. Applying uncertainty to aggregated costs essentially implies that variation in the cost of individual components is perfectly correlated. By disaggregating cost components they are being treated as uncorrelated, which can substantially reduce uncertainty in the total cost. In this case study we found that although the reduction in uncertainty could be clearly seen in the cost parameter, it had a negligible impact on uncertainty in the ICER.
