The redundancy allocation problem is a way to maximize reliability while minimizing the cost in this work a case study on a small scale industry is conducted to show the benefits of the using a. Solve the multiple objective redundancy allocation problems (morap) the single in practice, a decision maker or a system designer has to consider multiple objectives. Redundancy allocation based on the weighted mismatch-rate slope for multiple description video coding abstract: multiple description coding (mdc) is a robust coding . Abstract: reliability issues are most important types of optimization problems and they are used in communication, transportation and electrical systemsthis paper presents two mathematical models to solve the k-out-of-n redundancy problem where there are two objectives: maximization of reliability and minimization of cost subject to two constraints. Pruned pareto-optimal sets for the system redundancy allocation problem based on multiple prioritized objectives (goebel 2002) or weighted sum (geoffrion 1968 .
A multi-objective approach to redundancy allocation problem in are considered as two different objectives consequently, we solve the redundancy allocation . Expected weighted sum of the absolute deviations between the planned and the actually realized activity starting multiple objectives, whose first objective is to . 1 redundancy allocation based on weighted mismatch-rate slope for multiple description video coding mohammad kazemi, razib iqbal, shervin shirmohammadi. Optimal redundancy allocation in hierarchical cation problem with various objectives and different re- mization of a series system with multiple-choice and bud-.
Considering the increasingly high attention to quality, promoting the reliability of products during designing process has gained significant importance in this study, we consider one of the current models of the reliability science and propose a non-linear programming model for redundancy allocation in the series-parallel systems according to the redundancy strategy and considering the . One of actions which can be used in redundancy allocation is using multi-objective mathematical models allocation problem with objectives reliability and system . Alternative design redundancy allocation using an efficient heuristic and a honey bee mating algorithm multiple weighted objectives heuristic for the redundancy . Multiple objectives, a simulative process combined with an optimization process is proposed this process makes intensive use of computational power and can be deﬁned as.

One approach is proach is to combine the multiple objectives using the weighted to incrementally modify objectives heuristic for the redundancy allocation . A corridor method based hybrid algorithm for redundancy allocation authors multiple weighted objectives heuristic for the redundancy allocation problem ieee . Solving the redundancy allocation problem of redundancy allocation problem with two objectives, including maximization of the system availability and. We find that when reconstituting the s&p 500 universe from january 1996 through may 2014, using diversification optimization, we achieved annualized outperformance of 427 basis points against the capital-weighted benchmark, and achieved favorable results when compared against other weighted approaches applied to the same investments universe.
