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...

The Resource-constrained Project Scheduling Problem (Rcpsp), in which a schedule must obey the resource constraints and the precedence constraints between pairs of activities, is one of the most studied scheduling problems. An important variation of the problem (RcpspDc) is to find a schedule which maximises the net present value (discounted cash flow), when every activity has a given cash flow...

Lajos Juhász Institute of Corporate Economics Faculty of Economics NET PRESENT VALUE VERSUS INTERNAL RATE OF RETURN University of West Hungary [email protected] ABSTRACT. The economic professional literature which deals with investment decisions can be characterised in general that the net present value shows objective picture for the decision maker while the internal rate of return – not...

In order to identify independent predictors for bed net use, respondents from 643 households selected randomly from 21 clusters were interviewed in Mbarara municipality, Uganda. Respondents answered questions about demographic characteristics, social economic conditions, causes and transmission of malaria, beliefs about severity and complications of malaria, malaria morbidity and health care-se...
