Some data envelopment analysis models have been introduced in the literature that incorporate production trade-offs between inputs and outputs or, equivalently, weight restrictions imposed on their dual models. Podinovski has given a procedure, consisting of three stages, for practical application of such models (Podinovski, 2007). In this paper, we present a counterexample to the first stage o...

Our aim in this work is to determine returns to scale (RTS) under weights restrictions in data envelopment analysis (DEA). At first, we review Tone,s method (2001) proposed in this field, then by using a slack-based model, we introduce a new method that enables us to reach our aim. The advantage of the method proposed in this article over Tone,s method is that for determining returns to scale, ...

Scheduling is a common problem that has been raised for long time. Many algorithms have created this problem. Some offer flexibility in terms of constraints and complex operations. Because complexity, many will need huge computation resources execution A platform like web application restrictions such as time resources. algorithm not suited the platform. Priority scheduling based on priority qu...

OBJECTIVE Increasing numbers of infants born preterm survive into adulthood. In this study, we analyzed the effect of having been born preterm on disability and vocational success in young adults. METHODS A Swedish national cohort of 522,310 infants born in 1973-1979 were followed up for disabilities and income in national registers in 2002 at the age of 23 to 29. Hypotheses were tested in mu...

At present, there are no signs that global overweight and obesity rates are declining adding millions of more every year to suffer from uncontrolled body weight conditions. Conventional thinking of weight management is solely...

We give restrictions on the weight enumerators of ternary near-extremal self-dual codes length divisible by 12 and quaternary Hermitian 6. consider for which there is a code 12m $$m =3,4,5,6$$ . Also we 6m =4,5,6$$

Title of Thesis : System Performance Criteria in CDMA Networks Using Gold codes Yong H. Kim, M. S. E. E., 1988 Thesis directed by : Dr. Joseph Frank Associate Professor Department of Electrical Engineering First, we have presented the autocorrelation and crosscorrelation properties for periodic and aperiodic binary sequences. The generation of binary sequences using shift registers with feedbac...

Supplier selection is the process by which suppliers are reviewed, evaluated, and chosen to become part of a company’s supply chain. To select the best suppliers in the presence of cardinal data, ordinal data, nondiscretionary factors, and weight restrictions, this paper proposes a new model considering all of these assumptions. A numerical example demonstrates the application of the proposed m...
