This paper considers a revenue maximization problem on a single processor. Each job is identified as its processing time, initial reward, reward decreasing rate, and preferred start time. If the processor starts a job at time zero, revenue of the job is its initial reward. However, the revenue decreases linearly with the reward decreasing rate according to its processing start time till its preferred start time and finally its revenue is zero if it is started the processing after the preferred time. Our objective is to find the optimal sequence which maximizes the total revenue. For the problem, we characterize the optimal solution properties and prove the NP-hardness. Based upon the characterization, we develop a branch-and-bound algorithm for the optimal sequence and suggest five heuristic algorithms for efficient solutions. The numerical tests show that the characterized properties are useful for effective and efficient algorithms.

Since the beginning of civilization, people live in the times that changes rapidly everyday. Above all things, In April, 2004 the first opening of KTX(high-speed railway) that has been considered as the greatest revolutionary project shrinks the whole nation into a quarter of a day life zone and has repeated the constant change and development. But now, In comparison with ordinary train system KTX fails to notice revenue for travel-product and other many factors of increased revenue. This study introduces and analyzes the present condition of high-speed railway and indicate 'the plan to increase revenue' and 'the effect of creating revenue' through a travel-product on the basis of the travel-products connected with KTX. This study focuses on 'KTX memory train travel' and propose revenue and advertisement-effect created from targeting the middle-aged market. In addition, For improving KORAIL's image and approaching the customer more and more friendly, it grasp diverse events and advertisement plans.

The Real-Time-Pricing (RTP) brings greatest values in terms of economic incentives and efficiency among the dynamic pricing schemes. The electric power industry in Korea is mainly operated by publicly owned utilities and strongly regulated by the government; therefore, revenue reconciliation of RTP is inevitably required to prevent revenue deficits. In this paper, a revenue reconciliation of real-time pricing considering imperfect information on customer response is proposed to prevent revenue deficit and distortion of the spot price. A case study is present to verify the applicability of the proposed method.

A Health Promotion Center (HPC) whose capacity is partially idle causes inefficiency in resource usage of a country as well as the hospital itself. Meanwhile, Increased demand in HPC would lead to increased revenue for the HPC as well as reduced national expenditures on healthcare. We introduced a way to enhance revenue by Revenue Management (RM) on HPC services, in which demand forecasting and pricing strategies are considered. In addition, a real data analysis had been performed to evaluate the usefulness of the proposed approach.

The purpose of this study is to analyze outcome of the project to improve old water supply facilities in Airforce Base to improve water revenue rate. To achieve the objective of this study, First, literature review is conducted to clearly define the concept of water revenue rate improve project. Second, WASCO project on 2 Airforce base review and smart water management pilot project on 1 Airforce base is conducted. Third, economical analysis of project is conducted to examine the outcome. As a result, WASCO and smart water management pilot project on Airforce base was effective to improve water revenue rate. Finally, the improvements were suggested after investigating the key factors on water revenue rate improve project. In the future, this study will be used as a baseline for developing water revenue rate improve project.

We analyze the problems of the current system, develop and apply the revenue water ratio integration management system for problem solving, and present the analysis of the effect. It will contribute to the improvement of the revenue water ratio through systematic and efficient revenue water ratio management and reduction of the workload of the person in charge through the oil revenue water ratio integration system. It will contribute to the improvement of the revenue water ratio through systematic and efficient revenue water ratio management and reduction of the workload of the person in charge through the revenue water ratio integration system.

This study investigates the impact of tweets on box office revenue. Specifically, the study focuses on the times when tweets were written by examining the impact of pre- and post-consumption tweets on box office revenue; an examination that is based on Expectation Confirmation Theory. The study also investigates the impact of intention tweets versus subjective tweets and the impact of negative tweets on box office revenue. Targeting 120 movies released in the US between February and August 2012, this study collected tweet information on a daily basis from two weeks before the opening until the closing and box office revenue information. The results indicate that the disconfirmation that occurs in relation to the total number of pre-consumption tweets for a movie has a negative impact on box office revenue. This premise suggests that the formation of higher expectations of a movie does not always result in positive results in situations where tweets on perceived movie quality after watching spread rapidly. This study also reveals that intention tweets have stronger effects on box office revenue than subjective tweets.

Recently, Owing to booming of leisure activities and national enforcement of 5-day workweek system, Korean government has been promoting rural tourism policy of which operating project's title is Green Rural Experience Village, Rural Traditional Theme Village, etc. In this study, ken investigation result on Green Rural Experience Village sites, an estimation model of returns by green-tourism activities was developed. The model was constructed through factor analysis and regression analysis method. Regression model developed can estimate green-tourism revenue by investment budget, homepage preengagement sales, homepage visitors, capacity of eating and drinking facilities, capacity of lodging facilities. The model developed was applied in sample villages. With these results, estimation revenue was recorded average 138.3% of survey revenue, and statistical significance was good(correlation coefficient $R^2$ = 0.8255, level of significance : 0.000), and the range of relative error was recorded largely from -7.1% to 158.6%, and average relative error was 38.3% and good. And, the model developed in this study have the critical point in aspects of insufficient data, but the results will be used in green-tourism policies and projects, and revenue estimation about each village in the present and future is limited, but in province or the whole country the application is good.

As expansion of interest income business faces several limitations, non-interest revenue can play a vital role in increasing the net profit margin and the productivity of the assets to sustain the growth rate. This study aims to analyze the Effect level (partial or total) of a bank's size on the relationship between non-interest revenue and the sustainable growth rate of Jordanian commercial banks. Baron and Kenny's methodology (1986) was adopted to test and analyze the effect of non-interest revenue: including the bank's size, on the sustainable growth rate during the period from 2008-2019. Data collection was done for thirteen commercial banks which constituted 100% of the study population. Testing four hypotheses by using Amos program and a regression model to diagnose the partial and total effect of size. Findings indicate that there is a nonlinear relationship between Non-IR and SGR due to the total effect of bank size on the sustainable growth rate. The results of this study is expected to enable the banks to diversify their revenue to support financial performance towards healthy growth without facing additional financial problems. This study adopted a different methodology from the prior efforts, by using the mediation effect role to verify the effect of non-interest revenue.

The practice of revenue management has become increasingly important in a number of industries, notably in the airline, hotel, and rental car industries. A common interest of these industries is to maximize their revenue by developing a variety of products from perishable and limited resources over a finite time horizon. This paper provides review of revenue management models and classifies them with 2 different criteria. Finally, this paper concludes with several promising future research topics.
