water crisis resource management originates from limited resources has made it essential to study the prioritization of traditional and modern methods of sustainable water resource management. the objective of such studies is to provide a list of prioritized traditional and modern methods of sustainable water resource management. this research aims to study rainwater harvesting method and qanat...

for installing a large number of sizes and types of items (e.g., machines) over time so as to optimize some measure (e.g., initial capital investment), subject to various resource constraints. Examples of this problem are scheduling the installation of point-of-sale terminals in supermarket and retail chains, and teller terminals in banks. We have formulated the installation scheduling problem ...

We develop a bicriteria model for the resource allocation problem in PERT networks, in which the total direct costs of the project as the first objective, and the mean of project completion time as the second objective are minimized. The activity durations are assumed to be independent random variables with either exponential or Erlang distributions, in which the mean of each activity duration ...

Knapsack problem is a typical computer algorithm of NP complete (Nondeterministic Polynomial Completeness) problem. The research of solving this problem has great significance not only in theory, but also in application, for example, resource management, investment decisions and so on. For solving this problem, scholars have developed a number of algorithms, however, they are all have some draw...

Natural resource revenues provide a valuable source to finance public investment in developing countries, which frequently face borrowing constraints and tax mobilization problems. This paper develops a dynamic stochastic model to analyze the macroeconomic effects of investing resource revenues, making explicit the role of public investment inefficiency, absorptive capacity constraints, Dutch d...

Managers face a critical task in making firm investment decisions that are targeted toward creating and appropriating value. As managers weigh their resource investment decisions, we argue that these investments have a direct impact on the growth and volatility of the firm’s industry. With data covering 377 industries across 16 years, we investigate relationships for aggregate firm investments ...

Resource investment problem with discounted cash flows RIPDCFs is a class of project scheduling problem. In RIPDCF, the availability levels of the resources are considered decision variables, and the goal is to find a schedule such that the net present value of the project cash flows optimizes. In this paper, we consider a new RIPDCF in which tardiness of project is permitted with defined penal...

abstract this study aims to explore the impact of human resources investment on competitive advantage that incorporates human capital as a mediator variable. for this purpose a questionnaire was designed to collect data of the research variables. validity and reliability of measurement instruments was obtained using confirmatory factor analysis. questionnaire was then distributed among a sample...
