Optimal control is a very important field of study not only in theory but in applications, and stochastic optimal control is also a significant branch of research in theory and applications. Based on the concept of fuzzy process introduced by Liu, we present a fuzzy optimal control problem. Applying Bellman’s optimal principle, we obtain the principle of optimality for fuzzy optimal control, an...

in this paper, multi-objective uniform-diversity genetic algorithm (muga) with a diversity preserving mechanism called the ε-elimination algorithm is used for pareto optimization of 5-degree of freedom vehicle vibration model considering the five conflicting functions simultaneously. the important conflicting objective functions that have been considered in this work are, namely, vertical accel...

this paper presents a new approach which is based on quality control in order to optimize supplier selection. using inspections, removing the defected materials and considering penalties for low quality materials are the main factors which we have considered in modeling. in this model costs are divided to three parts: 1- costs of purchasing 2- costs of inspection policy 3- costs of quality and ...

Using k-Selection in Radio Networks as an example of unique-resource dispute among k unknown contenders, the conflict-resolution protocol presented in this paper shows that, for any sensible probability of error ε, all of them get access to such resource in asymptotically optimal time (e+1+ ξ)k+O(log(1/ε)), where ξ > 0 is any constant arbitrarily close to 0. This protocol works under a model wh...

1. Predicting the profitability and/or market share for proposed new product concepts given the current offering of competitors. 2. Predicting the impact of new competitor products on profits or market share if we make no change in our competitive position. 3. Predicting customer switch rates either from our current products to new products we offer (cannibalism), or from our competitors’ produ...

We present a general framework to study the project selection problem in an organization of fallible decision-makers. We show that when the organizational size and the majority rule for project acceptance are optimized simultaneously, the optimal quality of decision-making, as determined by the decision criterion, is invariant, and depends only on the expertise of decision-makers. This result c...
