A case of company manufacturing industrial valves is studied. To survive the fierce competition in the low-volume, high-complexity production environment, the company needs accurate information on the cost of its products. Current cost accounting system which allocates production costs based on the weights of intermediates and final products cannot provide accurate cost information that managers really need. Data on the company's cost structure and production processes were reviewed and managers were interviewed before problems with the current costing system were identified. Activity-based costing (ABC) system as well as an improved traditional costing system is considered to replace the current system. A prototype of ABC system is developed to better represent the relationships among the cost drivers, activities, and products.

Activity-Based Costing(ABC) is an accounting cost system which allocates the overhead cost to each cost object more accurately. ABC system achieves improved accuracy in estimating the cost of cost object by using multiple cost drivers to trace the cost of activities to the cost objects associated with the resources consumed by those activities. The selection and the aggregation of these cost driver candidates can pose difficult problems. This paper deals with these problems in mathematical programming approach. The first model is formulated as an integer programming model in cost driver selection and the second model is formulated as multi-objective goal programming model in reduction of cost drivers already selected.

When logistics system is integrated with production system and marketing system, it takes a very important role of the business management. In general, measurement of logistics cost in logistics system uses the conventional cost assignment method. However the conventional method may result in the incorrect cost because the overhead cost may be incorrectly assigned to the products. Activity-Based Costing(ABC) was proposed as an alternative method which will distribute the overhead cost to each cost obeject more accurately. ABC assigns cost to activities based on the amounts of resources used by resource driver, and assigns cost to cost objects based on the amount of activities driver. This study proposes two heuristic algorithms. The first algorithm selects the best activity driver for each cost object by using correlation analysis. The best activity driver is the one that minimizes the sum of loss cost and measurement cost of activity driver. The second algorithm selects the best number of activities by using correlation analysis. The pair of activities with the highest correlation are combined into one if the saving of measurement cost is no less than the loss due to inaccurate distribution of overhead cost. In order to demonstrate the procedure and validity of the algorithms, Real data of one year from a paper manufacturer are used.

The Activity Based Costing(ABC) means the process that makes clear how the actions and input resources have changed into service to calculate medical services costs. These days, the number of hospital which is using the ABC system is increasing to make their policy decision making efficient and run the hospitals more resonable. This study analyzes the unbalance in the level of health insurance service fee and the improvement plans based from 8 hospitals(ABC system) and 95 clinics(ABC survey). The cost recovery ratio has shown different levels according to each service type. A surgery service type recorded 76.8% and an evaluation & management service type is 84.6%, a treatment procedure type(85.8%), a function test type(91.6%) and health insurance fee even did not reach to the original cost. Meanwhile, a laboratory test type and imaging test type show high level of cost recovery ratio. they recorded 188.3% and 158.8%. Resultingly now of unbalance in the level of health insurance service fee accelerates supply of every test. so there is a need to make laboratory test type and imaging test type lower to keep balance with the surgery and medical service. These methods should be performed gradually with monitoring the unbalance fee ratio and for this, a panel medical institution have to be established for generalizations of studying result, fairness of selecting researching sample.

In the telecommunication industry, estimation of the cost of network facilities is very important since depreciation cost of the facilities accounts for a large portion of the product cost. Moreover, cost estimation in the industry becomes more difficult because of increasing indirect cost upon digital convergence, expanding multi-purpose facilities, complexity of service product, etc. Nevertheless, not much seem to have been done in improving estimation methodology of the cost of network facilities. As a result, the quality of cost information on network facilities has deteriorated, and now even decision-makers in the industry dismiss the information. Recently, two major telecommunication companies adopted a new network cost estimation method to deal with the issue. In this paper, we study the concept of new cost estimation method and the procedure to develop and apply it. We also suggest the method to carry out the cost allocation using Matlab which is more efficient and time-saving than other commercial cost calculation packages.

The purpose of this study was to examine the application of the Activity-based Costing(ABC) system to analyze the cost of nursing services in the delivery room in a major medical center.The results of this study are as follows;1. In order to calculate the cost of nursing activities, 67 activities of staff nurses on a delivery room were identified and classified as direct nursing activities(45.2%), the indirect activities(32.1%), general management activities(13.9%) and others(8.8%).2. Nursing cost in the delivery room was classified into activity cost(29.9%) and common cost(70.1%). Activity cost involved direct activity cost of staff nurses. The common costs were categorized into indirect activity & general management cost of staff nurses, management cost of the head nurse and activity cost of assistants.3. The final cost objects of nursing services in the delivery room were nursing service for women who had normal vaginal deliveries and nursing service for women who had preterm labor.The total cost of nursing service for a woman who had a normal vaginal delivery was 165,710 won (100.0%). The cost incurred through direct activity cost of staff nurses(58,242 won, 35.1%), indirect activity & general management cost of staff nurses (55,643 won, 33.6%), management cost of head nurse (16,211 won, 9.8%), activity cost of assistants (35,614 won, 21.5%).If the number of days of hospitalization was presumed to be 14 days, the total cost of nursing service for woman who had preterm labor would be 1,845,901 won (100.0%). The cost incurred by direct activity cost of staff nurses in the activity cost (341,349 won, 18.5%), indirect activity & general management cost of staff nurses in the common cost(779,002 won, 42.2%), management cost of head nurse(226,954won, 12.3%), activity cost of assistants in the common cost(498,596 won, 27.0%).In this study, the cost of the nursing services in the delivery room was calculated based on the ABC system. The results of this study showed that resources are assigned to the nursing activities in the delivery room and the mechanisms for assigning the cost of activities for nursing services.
