Resource limitation in zero time may cause to some profitable projects not to be selected in project selection problem, thus simultaneous project portfolio selection and scheduling problem has received significant attention. In this study, budget, investment costs and earnings are considered to be stochastic. The objectives are maximizing net present values of selected projects and minimizing v...

The Task Allocation problem runs oftentimes in project management. Artificial Intelligence is trying to finger out a solution to model this illstructured problem. In this paper, we propose an innovating multi – criteria approach, implemented in a decision support system, AgentAllocator. This multi – criteria method ends up with an optimal allocation plan. AgentAllocator is an easy to use applic...

Although a large number of studies have been made on modelling a multi-project scheduling problem, little is known about proposing a process which calls for the issues of project creation and selection, resource planning and project scheduling. Project advancement (PA) is a new approach involving such concepts. Seven-step rules of engaging the problem with constrained multi-tasking environment ...

In this paper, we test the applicability of a decision support system (DSS) that is developed to optimize the sequence of surgeries in the day-care center of the UZ Leuven Campus Gasthuisberg (Belgium). We introduce a multi-objective function in which children and prioritized patients are scheduled as early as possible on the day of surgery, recovery overtime is minimized and recovery workload ...

in this paper, a novel mathematical model for a preemption multi-mode multi-objective resource-constrained project scheduling problem with distinct due dates and positive and negative cash flows is presented. although optimization of bi-objective problems with due dates is an essential feature of real projects, little effort has been made in studying the p-mmrcpsp while due dates are included i...

evaluating and selecting alternatives investment projects needs considering all relevant and important aspects. in traditional methods, the focus is just on tangible monetary criteria. also in the traditional methods, either all the information’s about factors must be known precisely or sufficient objective data must be available for applying probability theory. in this paper, a combinative app...
