The Resource Constrained Project Scheduling Problem is an important problem in project management, manufacturing and resource optimization. We focus on a variant of RCPSP with time lags and uncertain activity durations. We adopt a Precedence Constraint Posting approach and add precedence constraints to the original project graph so that all resource conflicts are solved and a consistent assignm...

The paper studies a distributed iterative algorithm for optimal scheduling in grid computing. Grid user’s requirements are formulated as dimensions in a quality of service problem expressed as a market game played by grid resource agents and grid task agents. User benefits resulting from taking decisions regarding each Quality of Service dimension are described by separate utility functions. Th...

Many studies on the resource-constrained project-scheduling problem have been published, but literature further considering multi-mode or multi-project issues often occurring in the real world is rather scarce. In this research, two heuristic algorithms are developed to solve a multi-mode resource-constrained multi-project scheduling problem (MMRCMPSP). The first, a parallel scheduling algorith...

The aim of this study was to propose a model for human resource training at the Ministry of Sports and Youth. This research is practical from the objective point of view and it is complex (the combination of qualitative and quantitative methods) from nature perspective. The statistical population in the qualitative sector, including the experts of the Ministry of Sports, was knowledgeable and d...

Extracting semantic relations from texts is a good way to build and supply a knowledge base, an indispensable resource for text analysis. We propose and evaluate the combination of three ways of producing lexical-semantic relations.

In the last decade, there has been a lot of focus on sustainable development in the electrical power industry to meet the growing energy demand. This has led to an increase in the integration of renewable energy sources (RES). In addition to being abundantly available, the RES offers advantages such as low environmental impact and increased social development of rural communities which are impe...

The device for providing consolidation of preferential resource quality of service constraints specified by a source user and adestination user in a communication network has two quality of service translators receiving preferential resource constraintsinput from the source and destination users respectively. The translators translate input QOS requirements, for each of thesourc...

Background.  Multiple international treatment guidelines recommend amphotericin-based combination regimens for induction therapy of cryptococcal meningitis. Yet, only 1 trial has reported a mortality benefit for combination amphotericin-flucytosine, and none have reported a mortality benefit for combination amphotericin-fluconazole. Methods.  We conducted a Bayesian network meta-analysis to est...
