A problem cause identification software system is usually very complex and may contain multiroles dealing processes such as R&D, customer and manufacturing. The causes of a problem may have cognitive uncertainty properties, which need to be analyzed for the purpose of algorithm-based automatic problem-solving. In this study, an application of the scenario-driven agent-oriented analysis to a sof...

Object-oriented programming with ANSI-C requires a fair amount ... concentrate on the creative aspects of problem solving with better techniques. ooc.

Background and Purpose: Heart disease death rates have increased worldwide.Family-oriented empowerment model improves the quality of life in the patients with chronic diseases. This study aims to determine the effect of family-oriented empowerment model on the life quality of the patients undergoing coronary artery bypass graft. Methods: A quasi-experimental study was performed on the patien...

There have been many attempts to integrate object-oriented and functional programming. Solving the connicting requirements is dif-cult and only recently has a language, CLOVER, been designed that is both purely functional and purely object-oriented (and retains complete type safety). In this paper, we introduce the CLOVER rewrite rules by presenting a translation from CLOVER to a simple functio...

The existing Data Envelopment Analysis models for evaluating the relative eciency of a set of decision making units by using various inputs to produce various outputs are limited to crisp data in crisp production possibility set. In this paper, rst of all the production possibility set is extended to the fuzzy production possibility set by extension principle in constant return to scale, and th...

  In this paper, different input-oriented ratio-based DEA (DEA-R-I) models are proposed. By presenting the envelopment-additive-enhanced Russell model based on the DEA-R-I form, each decision making unit is evaluated and its efficiency score is calculated. Also, by presenting the central resource allocation model based on the DEA-R-I form, a suitable benchmark for all DMUs is proposed by solvin...

The theory of hierarchical Boolean satisfiability (SAT) solving proposed in this paper is based on a strict axiomatic system and introduces a new important notion of implicativity. The theory makes evident that increasing implicativity is the core of SAT-solving. We provide a theoretical basis for increasing the implicativity of a given SAT instance and for organizing SAT-solving in a hierarchi...
