The concept of revenue management have been used widely In the hotel and all transportation industries, and considered as a good system for managing a perishable asset. Recently, its' application area is being increasingly expanded to service industries such as the travel, the railway, the Internet and the sport industries. Internet business can be classified into several groups according to the characteristics of the individual business. One of groups is Internet Access Servoce business which connects each users to the internet. In this paper, since internet Access Services (IAS) business has a similar property to the service Industry, we will apply a revenue management concept to It. With some modification of existing model developed by Subramanian et.al. for airlines, we suggest the revenue management model being applied to IAS business. Computational experiment shows that the Increase of the revenue Is up to 7% by appluing our model. It means our model has a potential to manage IAS business effectively.

Electric utilities has been considered the necessity to introduce asset management of electric power facilities in order to reduce maintenance cost of existing facilities and to maximize profit. This paper aims to provide data that can helpful to make profitable decision in terms of power transformers which have a significant part in the power system. Therefore, this study is modeling input cost for power transformer during its entire life and also the life cycle cost (LCC) technique is applied. In particular, the variation of transformer state related with maintenance and the variation of the EUAC curve based on cost and effect of maintenance is examined. In this study, the trend of the equivalent uniform annual cost (EUAC) according to maintenance cycle and cost of equipment is analyzed. In line with that, sensitivity analysis influenced by the changes of other cost factors was performed.

Franchising is one of the most interesting areas of management research, attracting researchers and practitioners from all over the world. Many factors that drive franchising intention have been identified by previous researchers. They also demonstrated that there are numerous research gaps in this subject that must be filled. The primary goal of this study is to identify and test new factors of franchising intent. Finally, to clarify the role of these components, this study used the Motivation - Opportunity - Ability paradigm. To test the hypothesis, SmartPLS software was used to evaluate a total of 252 valid questionnaires collected from small and medium businesses in Hanoi, Vietnam. The findings revealed that franchisee motivation, franchisor support, and asset specificity have a positive impact on franchising intention. In whatever case, the opportunity has the greatest impact on participation intentions. In terms of the impact level on SMEs' intentions in the franchise system, ability comes in second. Furthermore, the moderating influence of franchisee asset specialization in the relationship between opportunity and franchising intention is confirmed by this study. This study examines the theoretical and practical contributions, as well as their limitations, and suggests some future research on the subject.

Cyber Mission Impact Assessment is one of the essential tasks which many militaries and industrial major companies should perform to effectively achieve their mission. The unexpected damage to an organization's assets results in damage to the whole system's performance of the organizations. In order to minimize the damage, it is necessary to quantify the available capacity of the mission, which can be achieved only with the remaining assets, and to immediately prepare a new second best plan in a moment. We therefore need to estimate the exact cyber attack's impact to the mission when the unwanted damage occurs by modeling the relationship between the assets and the missions. In this paper, we propose a new model which deals with the dependencies between assets and missions for obtaining the exact impact of a cyber attack. The proposed model distinguishes task management from asset management for an efficient process, and it is implemented to be optimized using a vectorized operation for parallel processing and using a buffer to reduce the computation time.

This study examines the impact of knowledge processes (KP) on the performance of knowledge management systems (KMS). It posits that task needs and available functionality of technology existing in an organization could influence the usability of KP and the KMS performance. A firm-level structural model was developed based on data collected from corporate KM users. Survey-based research was carried out to test this model. Following questionnaire development, validation, and pretest with a pilot study, data were collected from 886 knowledge management (KM) users including directors, managers, and workers in a South Korea-based company, Korea Asset Management Corporation (KAMCO), to measure the task needs and available functionality of technology to improve the KMS performance. Results show that the matching between the two factors-technology and task-had a significant influence on the usability of KP and the KMS performance, and a better usability of KP has positive impact on the KMS performance. Implications on KM practices and KMS designs are also discussed.

The cost needed to managing equipment is constantly increasing because of increase of power equipment. The regulations such as PAS 55 and ISO 55000 were enacted to manage equipment assets. The advanced management methods such as real-time monitoring, condition evaluation, and health indices are avalable in generation system, transmission system, and substation transformers. However, These methods can not be applied to distribution equipment because of a lot of equipment. Therefore reliability assessment is very important in case of distribution equipment. In this paper, failure rates are extracted considering characteristics of regions, and which are the essential factors to reliability evaluation.
