The completion time and nonrenewable resources are traditionally considered for construction of project. When renewable resources, quality and some criteria considered for the project, the risk related to criteria has to be taken into account. Thus project planning problem can be defined as multicriteria decision problem under risk. In this paper, a project scheduling problem including time, co...

We define and develop a solution approach for planning, scheduling and managing project efforts where there is significant uncertainty in the duration, resource requirements and outcomes of individual tasks. Our approach yields a nonlinear optimization model for allocation of resources and available time to tasks. This formulation represents a significantly different view of project planning fr...

Bio 4342 students are currently working on finishing the Drosophila grimshawi dot chromosome and a euchromatic region of Drosophila mojavensis. Project DMAC-1a (from D. mojavensis) began in two contigs with only a single macroscale problem and a few microscale problems. Using Consed and phredPhrap, this project has been finished to completion and is now in a single contig. This paper presents t...

Project planning functions are to establish project activities, their logical relationships and interrelationships to each other, and the sequences in which they are to be accomplished. The process of assigning activities' duration and identifying the start and completion times of activities and project is considered as project scheduling. Project planning and scheduling is one of the most impo...

Delay is a worldwide problem which normally occurs in every project. of the project when period time completion date late or postponed. Since delayed, cost will have escalation risk contractors. Instead getting benefit from project, they gain losses. Similarly, other construction projects different countries are prone to face delays. The aim this study summarise causes delay previous study. Reg...

In this paper, we consider the recognition problem on three classes of perfect graphs, namely, the HH-free, the HHDfree, and the Welsh-Powell opposition graphs (or WPO-graphs). In particular, we prove properties of the chordal completion of a graph and show that a modified version of the classic linear-time algorithm for testing for a perfect elimination ordering can be efficiently used to dete...

This study presents the effects of project uncertainties on nonlinear time-cost tradeoff (TCT) profile of real life engineering projects by the fusion of fuzzy logic and artificial neural network (ANN) models with hybrid meta-heuristic (HMH) technique, abridged as Fuzzy-ANN-HMH. Nonlinear time-cost relationship of project activities is dealt with ANN models. ANN models are then integrated with ...

The paper investigates the role of knowledge management in enabling project success, innovation, completion times, operational efficiency and the generation of new knowledge in development projects. Four projects in Uganda, Nigeria, and Cote d‘Ivoire were used as case studies. The objective was to explore the nature of knowledge management practices in these projects in order to see how they co...

We give the rst Goal-Directed version of the Knuth Bendix Completion Procedure. Our procedure is based on Basic Completion and SOUR Graphs. There are two phases to the procedure. The rst phase, which runs in polynomial time, compiles the equations and the goal into a constrained tree automata representing the completed system, and a set of constraints representing goal solutions. The second pha...

Preemptively scheduling a set of independent jobs with release time on one processor is a historical problem. In this paper, the same problem has been considered in which objective is to minimize the mean flow time. To prepare a perfect branch-and-bound, some optimality conditions have been represented and they have been compared with the optimality conditions which have been proposed before. O...
