maximizing economic earnings is the most common goal in cut-off grade optimization of open-pit mining operations. when this is the case, the price of the product has a critical effect on optimum value of cut-off grade. this paper investigates the relationship between optimum cut-off grade and price to maximize total cash flow and net percent value (npv) of operation. in order to visualize this ...

the aim of a multi-mode resource-constrained project scheduling problem (mrcpsp) is to assign resource(s) with the restricted capacity to an execution mode of activities by considering relationship constraints, to achieve pre-determined objective(s). these goals vary with managers or decision makers of any organization who should determine suitable objective(s) considering organization strategi...

The Resource-constrained Project Scheduling Problem (Rcpsp), in which a schedule must obey resource constraints and precedence constraints between pairs of activities, is one of the most studied scheduling problems. An important variation of this problem (RcpspDc) is to find a schedule which maximises the net present value (discounted cash flow). Large industrial applications can require thousa...

Improvement and expansion of the transmission grid is still an unresolved issue in the new competitive environment. In current electricity markets, transmission lines have become assets that need financial instruments for investors who wish to ensure steady long-term returns and to withstand short-term market volatility. The timing and the combination of new transmission investments is key to a...

The applicability of Net Present Value (NPV) in an investment project is becoming more and more popular in the field of engineering economics. The classical NPV methodology involves only the precise and accurate data of the investment project. In the present communication, we give a new mathematical model for NPV which uses the concept of intuitionistic fuzzy set theory. The proposed model is b...

We examine project scheduling with net-present-value objective and exponential activity durations, using a continuous-time Markov decision chain. Based on a judicious partitioning of the state space, we achieve a significant performance improvement compared to the existing algorithms.

Decisions about life annuities are an important part of consumer decumulation of retirement assets, yet they are relatively underexplored by marketing researchers studying consumer financial decision making. In this article, the authors propose and estimate a model of individual preferences for life annuity attributes using a choice-based statedpreference survey. Annuities are presented in term...

Trade credit represents a substantial portion of short-term credit for most firms. A trade credit decision is usually limited to a comparison of the effective cost of trade credit with the annual cost of borrowing. If the cost of not taking the cash discount exceeds the firm’s borrowing cost, the decision is to take the cash discount. This article examines traditional trade credit analysis, and...
