An Application of Reliability-analysis Techniques in Project Management
Journal Title: Journal of Advances in Mathematics and Computer Science - Year 2017, Vol 21, Issue 6
Abstract
This paper handles a prominent problem of project management, namely that of project scheduling under uncertainty. The paper models this problem as a vector-weighted voting system and expresses the indicator variable for the successful (on-time) completion of project activities as a vector-threshold Boolean function. The paper presents a solution of the problem in the Boolean domain using solely Boolean tools. The paper also presents another solution of the problem via recursive relations and boundary conditions. This solution is given as an insightful visual representation in terms of a signal-flow graph that resembles the Reduced-Ordered Binary Decision Diagram (ROBDD). The effect of the order of variables used in the recursive method is also explored.

Resolving Timetable Scheduling Problem Based on Bio-inspired Genetic Algorithm
Timetabling is the task of assigning sets of events to periods of time, taking into account resource-constraints and preferences among assignments. This involves combinatorial optimization, time-based planning, in order...
DT- optimality Criteria for Second Order Rotatable Designs Constructed Using Balanced Incomplete Block Design
Experimenters have come to a realization that a design can perform very well in terms of a particular statistical characteristic and still perform poorly in terms of a rival characteristic. Due to this studies have narro...

In this paper, we propose a viral infection model governed by three stochastic differential equations. The global existence and positivity of solutions is investigated. Further, we give sufficient conditions for the stab...
On Properties Related To *–Reversible Rings
In this paper, a class of *-rings which is a generalization of *–reversible rings is introduced. A ring with involution * is called central *–reversible if for a ,b∈R, whenever ab=0 ,b^* a is central in R. Since every *–...
