We consider the problem of optimal planning in stochastic domains with resource constraints, where the resources are continuous and the choice of action at each step depends on resource availability. We introduce the HAO* algorithm, a generalization of the AO* algorithm that performs search in a hybrid state space that is modeled using both discrete and continuous state variables, where the con...

during the implementation, construction projects usually encounter situation that considerably affects the project scheduling and cost. this study aims at using an improved version of the harmony search algorithm (hsa) to schedule resource constrained construction projects. this model is formulated as a global optimization problem. it will determine the duration of each activity to minimize the...

resource allocation and optimal leveling are among the top challenges in project management. this paper presents a dea-based procedure for determining an optimal level of inputs to produce a fixed level of outputs. to achieve this goal, we assume that the levels of outputs can be forecasted in the next season and the procedure will determine optimal level of inputs for all dmus. such as some of...

The aim of this paper is to establish and delineate a relationship between innovation strategy strategic planning toward firm performance based on both theories resource-based view diffusion theory. Successful firms are always aware effectively implement these strategies as powerful resource, in order ensure its survival among current potential rivals. Therefore, review previous studies find cr...

The nature of services in institutions of higher learning requires that all stakeholders play positive roles in the sustainability of the institution’s survival and effectiveness in giving quality teaching, research and learning. Structure and processes are core requirements for understanding organizational effectiveness. The actual scenario in the field, however, raises concerns as to whether ...

Cost effectiveness analysis is a systematic tool to inform resource allocation decision in healthcare. There is extensive evidence, however, that the tool is difficult to apply in practice, particularly at the level of local health planners, because it is not accessible to those involved in the prioritisation process and not embeds assumptions which are felt to be unacceptable for ethical or ot...

Assessing the performance of management is central to natural resource management, in terms of improving the efficiency of interventions in an adaptive-learning cycle. This is not simple, given that such systems generally have multiple scales of interaction and response; high frequency of nonlinearity, uncertainty, and time lags; multiple stakeholders with contrasting objectives; and a high deg...

BACKGROUND The current Ebola Virus Disease (EVD) outbreak in West Africa is the largest in history. As of February 18(th) 2015, 23,258 cases of EVD have been cumulatively reported from Nigeria, Senegal, Guinea, Liberia, Mali, Sierra Leone, Spain, the United Kingdom and the United States of America resulting in more than 9,000 deaths. It is therefore exigent to develop prevention and treatment t...
