Resource constrained project scheduling problem is one of the most important issues in project planning and management. The objective function of this problem is to minimize the completion time of a project. When there is budget constraint or high risk for investment, using the criteria such as cash flows is so important. The development of computer systems and processors makes it possible to t...

Business units are always faced with investment opportunities and need to make logical decisions on an optimal investment. Indeed, the investment of each business unit should be done with regard to the resource constraints and its effectiveness through the criteria for evaluating the projects including the net present value (NPV). The paper aims to investigate the effect of long-term debt on th...

Developing a complex software system involves decisions about how to allocate a limited resource budget among a collection of costly software alternatives (such as technologies or analysis techniques) that have uncertain future benefits. Very little quantitative guidance is currently available to make these decisions. We suggest that these allocation problems are naturally viewed in the powerfu...

A Resource Investment Problem with Discounted Cash Flows is a project scheduling problem in which the availability levels of the resources are considered decision variables and the goal is to find a schedule and resource requirement levels such that the net present value of the project cash flows optimizes. In this paper, we present a genetic algorithm to solve this problem. We explain the elem...

Virtualization-based server consolidation has been proven to be an ideal technique to solve the server sprawl problem by consolidating multiple virtualized servers onto a few physical servers leading to improved resource utilization and return on investment. In this paper, we solve this problem by using existing servers, which are heterogeneous and diversely preferred by IT managers. Five pract...

This study examines the impact of human capital on productivity of labor in Indonesia, using the ARDL analysis data method. This study uses the variable of human capital with a proxy level of labor education, the health status of labor and labor productivity. The data used are sourced from World Bank publications in the period of 1981-2014. The outputs of the analysis with the method of ARDL sh...

Given multiple products with unique lumpy demand patterns, this paper explores the determination of both the lot size for each product and the resource allocation among the products, given an investment budget for production rate improvements. Each product’s optimal production policy takes on only one of two forms: either continuous production or lot-for-lot production. A heuristic procedure de...
