Computerized cost estimation though cost model help user to estimating product cost since the early stage of product development. Total product cost is an economic indicator that a sustainable product promotes a good impact on the environment but also contribute a profit increased to the organization. In addition, the cost model could be a decision-making tool for the organization in selecting alternatives to replace the older system in term of financial and other benefits offered by the new technology. The proposed cost model helps membrane user to select the lower membrane system’s cost during its complete lifespan and it helps management to rearrange the production line and filtering system in reducing the total cost. Activity-based costing (ABC) useful in estimating the overhead cost, the total cost of the membrane system and also other useful information in improving the whole membrane system.

<p class="DRAbstrak">Cost estimation is the art of estimating the amount of cost required for an activity based on available information. The conceptual cost estimate is an early stage in planning a construction project. This estimate provides the cost that must be budgeted for a construction project. Cost conceptual estimates have low accuracy because the time of calculation and available information is limited. This study aims to obtain a conceptual model of the conceptual cost of short-spaced bridges. The method used is the cost index. The cost index is a figure indicating the cost per m2 of bridges at a given time. The required data are contract documents and drawings design that are built in 2012 - 2015 in Banyumas residency area. Span of bridge 4 - 38.8 meters and width of bridge 2 - 7 meters with caisson  foundation. The data were obtained from Dinas Bina Marga and Public Works Agency. The results showed that the conceptual cost model of reinforced concrete bridge with caisson foundation was BJiL = (100.540.56t2-404.528.636,58t + 406.914.286.088,58) x P x W, with t = year, P = span bridge, and W = bridge width. The error value of validation of this model is 2.31%.</p>

Cost structuring of new technology is a critical mission which needs to be developed systematically to get accurate cost estimation. In this research a new approach was proposed and developed for cost structuring a new process. Cost modeling roadmap was proposed to guide the development of genetic cost model by integrating different cost estimating methods and supporting the optimum solution by using statistical techniques in modeling the cost in high speed hard turning, then by building logical relationships between the different effective variables through three levels of cost drivers; main drivers, process and technical drivers and final drivers. Finally a matlab model was developed for simulating the final cost drivers to study the effect of different parameters on the cost drivers.

Cost Estimation Model

Apart from product quality, the manufacturing cost is an important element to compete in the competitive industry. Detail economic assessment is important to estimate the product cost accurately and avoid overestimating or underestimating that give bad impact to the firm. Membrane system; a compact, sustainable and cheaper wastewater treatment system compared to the traditional system. Yet, there is limited study analysing the economic aspect of the membrane system due to the limited historical data, a complicated process involved and deal with tangible overhead costs. Thus, this study aims to develop a cost model to estimate the total cost of the membrane system during its lifespan. Activity-based costing (ABC) method is used as cost estimation technique to calculating the overhead cost and added the direct costs to determine the life-cycle cost (LCC) of the membrane system by using Microsoft Excel while Microsoft Visual Basic is used to demonstrate a user-friendly cost estimation model. The proposed cost model is a simpler system because the end user is guided to get the LCC value without has to deal with a complicated equation. The proposed model cost is tested to estimating the LCC of HFMM in treating wastewater from the prototype stage until the disposal stage.

Locally load-optimized fiber-based composites, the so-called tailored textiles (TT), offer the potential to reduce weight and cost compared to conventional fiber-reinforced plastics (FRP). However, the design of TT has a higher complexity compared to FRP. Current approaches, focusing on solving this complexity for multiple objectives (cost, weight, stiffness), require great effort and calculation time, which makes them unsuitable for serial applications. Therefore, in this paper, an approach for the efficient creation of simplified TT concept designs is presented. By combining simplified models for structural design and cost estimation, the most promising concepts, regarding the cost, weight, and stiffness of TT parts, can be identified. By performing a parameter study, the cost, weight, and stiffness optima of a sample part compared to a conventional FRP component can be determined. The cost and weight were reduced by 30% for the same stiffness. Applying this approach at an early stage of product development reduces the initial complexity of the subsequent detailed engineering design, e.g., by applying methods from the state of the art.

The cost management system is a powerful tool for managers to understand manufacturing plant performance. It is essential for any organization to develop a cost management system to estimate the product cost and to account actual cost spent for the product manufacturing. The Activity Based Costing (ABC) system has recently attracted the attention of many companies and is considered to provide better information about the cost pattern and the relationship between resources and activities. However, a survey of earlier research reveals that there are several difficulties to estimate the true product cost due to selection of overhead drivers to activities. To overcome these difficulties Temporal-ABC has been developed by Dr. K.D. Tham. In the first part of the report, costing system implementation issues are studied through real-time case studies. Then, research has been conducted and web-based proptotype application is developed using Temporal-ABC through collaboration with a world-class electronics industry - Celestica Inc. Toronto, Canada. The developed prototype demonstrates the application of Temporal-ABC for cost estimation at Celestica.

INTRODUCTION: Childhood immunisation is one of the most cost-effective activities in health care. However, New Zealand (NZ) has failed to achieve national coverage targets. NZ general practice is the primary site of service delivery and is funded on a fee-for-service basis for delivery of immunisation events. AIM: To determine the average cost to a general practice of delivering childhood immunisation events and to develop a cost model for the typical practice. METHODS: A purposeful selection of 24 diverse practices provided data via questionnaires and a daily log over a week. Costs were modelled using activity-based costing. RESULTS: The mean time spent on an immunisation activity was 23.8 minutes, with 90.7% of all staff time provided by practice nurses. Only 2% of the total time recorded was spent on childhood immunisation opportunistic activities. Practice nurses spent 15% of their total work time on immunisation activity. The mean estimated cost per vaccination event was $25.90; however, there was considerable variability across practices. A ‘typical practice’ model was developed to better understand costs at different levels of activity. CONCLUSIONS: The current level of immunisation benefit subsidy is considerably lower than the cost of a standard vaccination event, although there is wide variability across practices. The costs of delivery exceeding the subsidy may be one reason why there is an apparently small amount of time spent on extra opportunistic activities and a barrier to increasing efforts to raise immunisation rates.

We propose a maintenance policy for new equipment on a repair-refund maintenance strategy in this paper and derive the optimal lease period from the lessor’s perspective based on independent and identical distribution of historical failure data which obey power law process. The cost model of a full refund and a proportional refund is studied, and the corresponding optimal leasing period is determined by reducing the expected total cost rate to the largest extent. We use a numerical example to illustrate the proposed cost model and analyze the sensitivity of related parameters. Furthermore, we show that the proportional refund policy is preferable than a full refund to the lessor. Finally, according to the simulation outcome, the proposed methods are effective and instructions for lessor in regard to equipment lease are provided.

Formal methods for measuring the impact of interoperability on digital public services is emerging as an important research challenge in electronic government. The eGOVSIM model that is described in this chapter aims to provide administrations with a tool to calculate the gains from digitising and making interoperable services for citizens and businesses. The chapter presents existing methods for calculating the cost of services for the administration and the service consumers, such as the Standard Cost Model (SCM) and the Activity Based Costing (ABC). Then it goes on presenting a toolset for analytical cost calculations based on the various process steps and the information needs of each governmental service. The eGOVSIM toolset supports the definition of several service provision scenarios, such as front/back office system interoperability, cross-system or cross-organisational interoperability allowing the calculation of time, effort and cost elements, and relevant gains from the application of each scenario. Application results for two cases / scenarios are also presented, so that the reader can see the applicability and overall value of the approach. Lessons learned and future research directions for service cost estimation are also described.

The Cost

The cost of medical procedures is often unknown, but is nevertheless crucial for setting reimbursement and health care policies. The cost of an upper gastroduodenal endoscopy was investigated in ambulatory adults in a large academic hospital in the province of Quebec, from the perspective of the hospital.An activity-based costing methodology was used to break down the procedure into a number of priory tasks, to which resources used at the department level (labour, equipment, materials) were allocated. The direct cost of performing an endoscopy ranged from $62 for an unsedated, unbiopsied patient to $89 for a sedated, biopsied patient. Not included in this amount were separate reimbursement fees of $15 for biopsy analysis and the $50 professional fee for the performing physician, which are charged directly to the Ministry of Health.Incorporating overall, general hospital fixed overhead costs raises the cost of the procedure substantially, by $41, as does the use of nonreusable biopsy forceps, which adds about $63 to the total cost of the procedure.Given the high proportion of overall, hospital-wide, overhead costs in the total cost of the procedure, allocation methods of these overhead costs in current hospital accounting systems should be improved to obtain a more precise estimate of the full cost of upper gastroduodenal endoscopy.
