As economic pressure and competition for budget among federal agencies has increased, there has been an increasing need for more granular data and robust management information systems. This is especially true for the execution of major civilian space programs. This need has resulted in new program management requirements being implemented in an attempt to limit cost and schedule growth. In par...

Time–cost trade-off problems (TCT) are well-known in project management contents. This approach normally applied for scheduling of a project especially where the project should be completed under pre-determined deadline. This paper aims to extend time-cost trade-off (TCT) problems in order to provide a well-organized mechanism for both scheduling and rescheduling processes of a project. The pro...

Context: To meet the growing need for education in Software Project Management, educational games have been introduced as a beneficial instructional strategy. However, there are no low-cost board games openly available to teach Earned Value Management (EVM) in computing programs. Objective: This paper presents an educational board game to reinforce and teach the application of EVM concepts in t...

The study aims to identify the factors that affect lowland rice production, analyze efficiency of using production farming, and calculate farmers’ income farming in Balige Sub-district Toba Samosir Regency. research was conducted Hutagaol Peatalun Village Hinalang Bagasan with 64 respondents. Farmer respondents were chosen a simple random sampling method. collected data analyzed by Cobb-Douglas...

The object of this study was to find out how much value-added and profit from the business treating cassava into tape at home industry Bu Asni Fajar Harapan Village, North Kluet District, South Aceh Regency. research location determined purposively (deliberately), considering that Regency is an area produces a lot sweet potato tape. conducted in January 2022. Hayami method calcifies added value...

How does reward guide spatial attention during visual search? In the present study, we examine whether and how two types of reward information-magnitude and frequency-guide search behavior. Observers were asked to find a target among distractors in a search display to earn points. We manipulated multiple levels of value across the search display quadrants in two ways: For reward magnitude, targ...

Earned value management (EVM) is widely used when monitoring and estimating operations related to construction projects. As the scope complexity of projects expand, traditional EVM sometimes ineffective even results in conclusions that are contrary actual situation. Additionally, estimate produced by a deterministic does not account for uncertainty activities involved project. This study propos...

The aim of this study is to present a new method to predict project time and cost under uncertainty. Assuming that what happens in projects implementation which is expressed in the form of Earned Value Management (EVM) indicators is primarily related to the nature of randomness or unreliability, in this study, by using Monte Carlo simulation, and assuming a specific distribution for the time an...

Abstract: Social inequality is traditionally measured by the Gini-index (g). Most of the estimates of the income or wealth data indicate the g value to be widely dispersed across the countries of the world: g values typically range from 0.30 to 0.65 at a particular time (year). We estimated similarly the Gini-index for the citations earned by the yearly publications of various academic institut...
