This paper mainly focused on the life cycle cost collection of manufacturing product based on web and data organization methodology according to business requirements. The general features of manufacturing product life cycle cost were analyzed at first while cost collection objects and cost-related product features were chosen. After that, the software system was developed using .NET and C# web programming technique picking up cost data from credible websites on Internet. Then, life cycle cost data warehouse model was designed via features of cost collection object ending up with the establishment of data warehouse system acquiring cost data as data source. Basic data cleaning and data validation function was developed to meet data quality demand referring to data integrality, data authenticity and data time effectiveness. Finally, an exemplification system of family cars was set up successfully assembling 300 thousand plus records about 3500 car models in last 26 months. This system was proved to work without human manipulation over hours visiting 10 thousand web pages and collecting cost data. This proved the software was valid.

Set Up

The analysis of ventilation strategies is fundamentally affected by regional climate conditions and local cost databases, in terms of energy consumption, CO2 emission and cost-effective analysis. A systematic approach is covered in this paper to estimate a local economic and environmental impact on a medium-sized space located in two regions during supply-and-installation and operation phases. Three ventilation strategies, including mixing ventilation (MV), displacement ventilation (DV) and stratum ventilation (SV) were applied to medium-sized air-conditioned space with this approach. The trend of the results for three ventilation systems in the life cycle assessment (LCA) and life cycle cost (LCC) analysis is SV < DV < MV. The result of CO2 emission and regional LCC shows that SV is the lowest one in both regional studies. In comparison with the Hong Kong Special Administrative Region (HKSAR) during 20 Service years, the case analysis demonstrates that the percentage differences in LCC analysis of MV, DV & SV in Guangdong are less than 20.5%, 19.4% and 18.82% respectively. Their CO2 emission of MV, DV and SV in Guangdong are more than HKSAR in 10.69%, 11.22% and 12.05%, respectively. The present study could provide information about regional effects in the LCA and LCC analysis of three ventilation strategies emissions, and thereby help set up models for decision-making on high efficiency and cost-effective ventilation strategy plans.

Abstract Mass timber building materials such as cross-laminated timber (CLT) have captured attention in mid- to high-rise building designs because of their potential environmental benefits. The recently updated multistory building code also enables greater utilization of these wood building materials. The cost-effectiveness of mass timber buildings is also undergoing substantial analysis. Given the relatively new presence of CLT in United States, high front-end construction costs are expected. This study presents the life-cycle cost (LCC) for a 12-story, 8,360-m2 mass timber building to be built in Portland, Oregon. The goal was to assess its total life-cycle cost (TLCC) relative to a functionally equivalent reinforced-concrete building design using our in-house-developed LCC tool. Based on commercial construction cost data from the RSMeans database, a mass timber building design is estimated to have 26 percent higher front-end costs than its concrete alternative. Front-end construction costs dominated the TLCC for both buildings. However, a decrease of 2.4 percent TLCC relative to concrete building was observed because of the estimated longer lifespan and higher end-of-life salvage value for the mass timber building. The end-of-life savings from demolition cost or salvage values in mass timber building could offset some initial construction costs. There are minimal historical construction cost data and lack of operational cost data for mass timber buildings; therefore, more studies and data are needed to make the generalization of these results. However, a solid methodology for mass timber building LCC was developed and applied to demonstrate several cost scenarios for mass timber building benefits or disadvantages.

Setting of tolerances to meet a required specification of quality characteristic and keep low manufacturing cost is one of common problems in the process quality control. But generally traditional tolerance design only focus on cost of manufacturing, few consider product Life Cycle Cost. In these situations, to obtain a satisfactory six sigma quality level as well as keep lower life cycle total cost should be considered. This paper expands tolerance optimization based on the manufacturing cost to the product life cycle cost, which can improve product quality to the six sigma level and keep lower LCC simultaneously.

Product Disassembly

Disassembly sequence planning not only reduces product life cycle cost, but also greatly influences environmental impact. Industrial recycling and remanufacturing involves product disassembly to retrieve the desired parts and/or subassemblies by separating a product into its constituents. Disassembly has recently gained a great deal of attention in the literature due to its role in product recovery. Disassembly sequencing and planning is more challenging than assembly because its terminal goal is not necessarily fixed, but may depend on product usage and market demands for used parts and recycled materials. Moreover, disassembly is accompanied by more uncertainty in system structures and component conditions than is assembly. This paper presents recent methods for sequencing and process planning in disassembly and the applications to industrial products. This research is aimed at determining the optimal disassembly sequence as well as the helps to find the sequence dependent cost.

The Cost

In order to survive in today’s competitive global business environment, implementation of life cycle costing methodology with a greater emphasis on cost control could be one of the convincing approaches for the manufacturing firms. The product life cycle costing approach can help track and analyse the cost implications associated with each phase of product life cycle. Life cycle costing (LCC) practices with traditional costing methods may provide results that have a severe deviation from the real product LCC as it focuses on the cost of materials, labor and a low portion of overheads apportioned by the absorption rate to the product. Activity based costing (ABC) has emerged as one of the several innovative and more accurate costing methods in recent years. It is based on the principle that products or services consume activities and activities consume resources that generate costs. Thus, the ABC system focuses on calculating the costs incurred on performing the activities to manufacture a product. This paper presents a LCC modeling approach for estimating life cycle cost of pumps using activity based costing method. The study was conducted in a large pump manufacturing company from India that has significant global standing within its industry. Firstly, all the activities and cost drivers associated with the life cycle of a pump have been identified. A methodology for LCC analysis using ABC is then developed and it is applied to two different pumps manufactured by the same industry and the results obtained are presented.

This research was - case study in Rstin company for the steel structures in Erbil- addressed the cost technique of product life cycle, as discussed the kinds, relevance and the stages of the life cycle of the product, also it referred to the corporate governance of discussing its inception the concept and importance of the principles, objectives, and mechanisms was addressed to the technical aspects of the overlap between the cost of the product life cycle corporate governance and show the appropriate techniques used in each stage of the life cycle of the product and how it achieved by a reduction of costs. The result of this study indicates that the integration between the product life cycle cost and corporate governance works on reduce costs through the various stages of product life cycle. It also concluded that this integration increases the company ability to compete in market which leads to rise in its market share and eventually lead to maximize the profit which has been achieved through the optimal use of a company available resources. It also found that the techniques of life cycle cost of the product cannot be applied without support of the company directors, throughout the technical requirements of the application. Corporate governance ensures directors of the company to utilize firm resources which makes the company to achieve several stakeholders' objectives.
