Implementing effective cost management approaches has recently gained momentum due to intense competition and increasing customer demands. Moreover, effective cost management approaches have contributed to firms' competitive advantage in relation to cost leadership strategy. Consequently, firms have implemented contemporary cost management systems, such as activity-based management, business process re-engineering, life-cycle costing, target costing, and theory of constraint (TOC), to enable them to become low-cost producers and compete effectively and sustain their performance. Furthermore, focusing on cost management to improve profitability has led to the integration of activity-based costing (ABC) and TOC. Therefore, the aim of this study is to review literature and discuss how integration of ABC and TOC can result in improved and sustained cost management. While these methods have different approaches in addressing cost management, treating them as complementary cost management approaches can result in improved cost management due to improved product costing, improved cost reporting, improved product-mix decisions, and improved cycle-time management. Improvement in cost management will then result in sustained cost management. Sustained cost management is further enhanced with the investment in information customer and shareholder value technology that supports cross-functional decision making to continue creating to remain competitive in the market. 展开更多

On the basis of analysis and selection of factors influencing operation cost of coal resources development, fuzzy set method and artificial neural network (ANN) were adopted to set up the classification analysis model of coal resources. The collected samples were classified by using this model. Meanwhile, the pattern recognition model for classifying of the coal resources was built according to the factors influencing operation cost. Based on the results achieved above, in the light of the theory of information diffusion, the calculation model for operation cost of coal resources development has been presented and applied in practice, showing that these models are reasonable. 展开更多

In order to evaluate and estimate me cosEs oi prouuct~ plt, uu^u e vironment properly, an improved activity-based costing (ABC) model is presented. By utilizing the input-output analysis method, the complex consumption relationships in a complex manufacturing environment are first expressed. The consumption characteristics (mainly presented by the activity rates) of all production activities are extracted by solving these relationships. Then with the con- sumption characteristics and operating parameters of these activities, the detailed cost consumption of a product in its manufacturing process is estimated. A case study is finally given based on the compressor products of a manufacturing company, and its effectiveness is shown. As the cost influ- ence of complex consumption relationships is fully considered, the limitation of traditional ABC method is overcome, and therefore a high accuracy in product cost estimation under the complex manufacturing environment can be achieved. 展开更多

An organization’s costing system is a system that helps the management with the strategy planning while the system plays an important role in providing accurate cost information about the products and customers.In other words,the costing management system is important to provide timely and quality information to help managers in their decision-making process.Producing quality graduates is the main objective of any university and the cost of quality or the cost of poor quality is one that is often difficult to measure in higher education.This can be partly attributed to the fact that most accounting systems are not structured to capture important cost-of-quality information.In order to succeed,many organizations tend to shift from conventional or traditional costing system to Activity-based costing(ABC).ABC provides both higher education administrators and policymakers with better information on which to base decisions.The use of multiple cost pools and drivers under ABC leads to more detailed and accurate product costing than that provided by traditional cost systems.This paper attempts to investigate the possibilities and limitations of implementing ABC in universities.More specifically the study makes use of the case study method to illustrate the implementation of activity-based costing of library services in a private university in the Kingdom of Bahrain.The research methodology of the case study is a combination of both descriptive and quantitative analyses.The study identified six categories of cost pools which are related to the activities of the library as well as 17 relevant cost drivers.Accordingly,ABC should lead to a better understanding of what drives costs and,by extension,what changes are necessary to reduce costs.Unnecessary activities that do not add value to services can be identified and eliminated.Further ABC is feasible in an academic library and that much can be gained from the process of analyzing activities.However,more work needs to be done in terms of designing accounting and other information systems to capture cost and activity transaction data in a more routine and disaggregated form for ABC analysis. 展开更多

Based on the theory of activity-based costing and the idea of value chain,activity optimization and cost control are carried out on the whole construction process of agricultural water conservancy projects. Through the use of literature review,case analysis and statistical analysis and other methods,with agricultural water conservancy projects as the research object,and comparing activity-based costing with the traditional model of cost accounting,the writer carries out the corresponding value chain analysis,and comes to the following conclusion: the statistical calculation and analysis of the entire construction process based on activity-based costing can accurately and effectively control the costs of water conservancy projects. Through the use of activity-based costing,the cost data of agricultural water conservancy projects is more detailed and accurate,and cost management personnel can also find non-value-added activities,optimize the enterprise's value chain and achieve cost control objectives through the analysis of the activity chain and value chain of agricultural water conservancy projects. 展开更多

Road transport is a flexible mode of transport and its importance in era of globalization increases. Management of road transport companies is, in this turbulent environment, exposed to many technical, legislative, and economic problems. Especially, the growing economic pressure leads to an urgent requirement of the manager and control system improvement. Activity-based costing (ABC) method is a very powerful tool to improve products, services, processes, and market strategies. ABC allows company management to understand what causes costs and how to manage them. Company under this scheme may get a glimpse of how efficiently a company converts the source value. The main objective of our research was to assess the possibility of application of the ABC method in a transport undertaking. ABC method as a fundamentally different view on the cost in the transport business helps to find the reasons of cost and thereby influences their levels to make better use of resources.. New managerial accounting methods aim to show management what information is needed, how and where this information can be obtained, and how they can be useful for the management of the company's proper planning, decision-making, and control. Information provided by management accounting is often a key factor in the analysis of alternative ways of solving problems. This article focuses on the transport enterprise management and helps to decide on the use of this method in business practice. 展开更多

This article analyzes the development of an activity-based costing (ABC) system in a private Italian healthcare firm. Findings shed light on the role of the cost accounting system in price assessment: It outlines new opportunities for the identification of the service mix offered as well as for price optimization. Because private companies provide services both within the public system--where the National Health System (NHS) provides fixed reimbursement fees--and within the private system--where prices are defined by each company. Accurate cost information is extremely important to support managers in the analysis of the service mix profitability offered in each system. For the business segment in which companies do not have flexibility in setting prices, cost information enables managers to identify services which may present profitability problems. For the business segment where price flexibility exists, cost information supports the identification of pricing errors so that charges can be better defined. 展开更多
