An Improved Estimation of Averaged Ranks of Partial Orders
نویسندگان
چکیده
Comparison of objects characterized by a multitude of criteria will typically not lead to a linear order, but to a partial order. However, often a linear order is desirable or even required. The present paper presents an improved – extended – approximate local partial order model to estimate a weak or linear order based on averaged ranks of the studied objects originally being partially ordered. The paper analyses various possible partial order scenarios by means of the new local partial order model, the results being compared to the original approach as well as to exact values (their calculation can be extremely time consuming), demonstrating a distinct improvement of the extended method compared to the original local partial order ranking method. By the approximate methods the values of averaged ranks can be understood in terms of three basic partial order parameters. The method is applied to current research on human health effects of rocket fuel transformation products.

Estimation in ARMA models based on signed ranks
In this paper we develop an asymptotic theory for estimation based on signed ranks in the ARMA model when the innovation density is symmetrical. We provide two classes of estimators and we establish their asymptotic normality with the help of the asymptotic properties for serial signed rank statistics. Finally, we compare our procedure to the one of least-squares, and we illustrate the performa...
متن کاملA Batch-wise ATP Procedure in Hybrid Make-to-Order/Make-to-Stock Manufacturing Environment
Satisfying customer demand necessitates manufacturers understanding the importance of Available-To-Promise (ATP). It directly links available resources to customer orders and has significant impact on overall performance of a supply chain. In this paper, an improvement of the batch-mode ATP function in which the partial fulfillment of the orders is available will be proposed. In other words, in...
متن کاملTensor Network Ranks
In problems involving approximation, completion, denoising, dimension reduction, estimation, interpolation, modeling, order reduction, regression, etc, we argue that the near-universal practice of assuming that a function, matrix, or tensor (which we will see are all the same object in this context) has low rank may be ill-justified. There are many natural instances where the object in question...
متن کاملCompleteness and Definability of a Modal Logic Interpreted over Iterated Strict Partial Orders
Any strict partial order R on a nonempty set X defines a function θR which associates to each strict partial order S ⊆ R on X the strict partial order θR(S) = R ◦ S on X. Owing to the strong relationships between Alexandroff TD derivative operators and strict partial orders, this paper firstly calls forth the links between the CantorBendixson ranks of Alexandroff TD topological spaces and the g...
متن کاملOn orders induced by implications
In this paper, the orders induced by the residual implications obtained from uninorms are investigated. A necessary and sufficient condition is presented so that the ordinal sum of fuzzy implications satisfies the law of importation with a t-norm $T$. Some relationships between the orders induced by an ordinal sum implication and its summands are determined. The algebraic structures obtained fr...
