The cost estimation of the product life cycle was researched. On the one side, the life cycle cost present value for manufacturer was estimated, including mainly of target cost, service cost and fault compensation. And a life cycle cost estimation model for manufacturer, which combines target cost and proportion cost estimated, was proposed. On the other side, the life cycle cost present value for user was estimated, including mainly of purchase, installation, commissioning costs in beginning and labor, maintenance, depreciation, maintenance costs in operations. And another life cycle cost estimation model for user, which combines process cost and proportion cost estimated, was proposed.

The highway engineering is an important area for investment in infrastructure construction in China, in the stage of engineering design, to solve the difficult problem of life cycle cost estimates, the paper builds the highway engineering life-cycle cost estimation modular conceptual model, and develops the highway engineering LCC estimation modular platform under the model. It provides a practical way for the highway life cycle cost measuring, and presents a new idea for life cycle cost estimation model.

Saving energy is one of the basic national policies, and energy efficiency in building is the important part of energy conservation work. It is of great significance to develop this work permanently. Discusses the definition of energy efficiency in building, introduces the concept of the life cycle, and sets up the life cycle cost estimation model. Through the analysis of energy saving building, comes to an important conclusion. Although the initial investment of energy saving building increases, the whole life cycle cost is obviously lower than general building. With the increasing of the discount rate and the extension of life cycle, the effect is more outstanding.

In competitive environment, manufacturers have to come out with innovative solution to market their product including by implementing life cycle engineering concept. Life cycle costing (LCC) is one of the aspects that need to be considered when adapting this concept. In addition, costing is one of the important aspects that need to consider carefully. In order to perform LCC analysis, one of the important steps is estimating costs. Cost estimation model should not only consider pre production and production cost design, manufacturing, assembly but also post production customer use and end of life. Development of cost estimation model or methodology is needed to simplify the LCC analysis so that it able to produce result in short time and more accurate. This paper has review on LCC, cost estimation techniques and several developed cost estimation model in order to determine research gap and research direction on developing a methodology to assessing LCC of membrane system for wastewater filtration.

Optimal costing decisions are required in order to ensure that organisations are globally competitive. The case study company is a global affiliate based in Durban, KwaZulu-Natal, South Africa and is involved in the manufacture and assembly of automobiles and automotive components. It was noticed that cost estimation models were only introduced at an advanced stage in the project life cycle. The concept of cost estimation and its application to improve various factors of a business has been investigated previously and existing evidence could be utilised to support further study in the field. Therefore, the aim of the study was to improve the quality of sourcing decisions by means of the introduction of a parametric cost estimation model and business process re-engineering. A case study approach was adopted. The first objective was to develop an overview of the current sourcing processes and understand the factors which influenced sourcing decisions. The methods used included the generation of a Standard Operating Procedure (SOP) for the current sourcing process, an online survey and interviews. It was concluded that there was a need to develop a detailed SOP which identified and included all impacted departments. The second objective was to redesign the sourcing process. It was concluded that the current sourcing processes did not take cost estimates into account at the early stages of the project life cycle and the inability to accurately predict costs consequently negatively impacted the cost competitiveness of the organisation. The third objective was to develop and implement a parametric cost estimation model. The model was created using Microsoft Excel. The results revealed that the Parametric Cost Estimation Model (PCEM) needed to focus on small injection moulded components as they were the highest contributor to the high Cost Index Manufacturing (CIM), which made the organisation globally uncompetitive. The results revealed that with the introduction of the PCEM and the revised sourcing process, the selected component was competitively priced.Recommendations were made for continuous process improvement and a roadmap for the further introduction of cost estimation models. Further research could also be conducted to develop an optimal cost estimation model based on analogous costing techniques or to develop a comprehensive database for other complex commodities.
