Pigeons responded in a perceptual categorization task with six different stimuli (shades of gray), three of which were to be classified as "light" or "dark", respectively. Reinforcement probability for correct responses was varied from 0.2 to 0.6 across blocks of sessions and was unequal for correct light and dark responses. Introduction of a new reinforcement contingency resulted in a biphasic...

rapid technological and economic growth over the last several decades has changed human lives and made modern society face complex decision making problems. these kinds of problems are characterized by incommensurate and conflicting criteria or objectives such as cost, reliability, performance, safety and productivity. multi criteria decision making is an approach that can be used to deal compl...

Aiming at stochastic multi-criteria decision problems brought by criterion value with extended grey number, a grey stochastic multi-criteria decision-making method based on Hausdorff distance is proposed. Firstly, definitions, calculation rules and distance formulas of expanded grey number random variables and expectations are given. Then based on grey decision matrix and natural state probabil...

Six Sigma is a strategy for achieving process improvement and operational excellence within an organization. Decisions on critical parameter selection in analysis phase are always very crucial; it plays a primary role in successful execution of Six Sigma project and for productivity improvement in manufacturing environment and involves the imprecise, vague and uncertain information. Using a cas...

İş Sağlığı ve Güvenliği (İSG) faaliyetleriyle işyerlerinde çalışanların ruhen bedenen tam bir iyilik halinde olması hedeflenmektedir. Bu faaliyetlerin en önemlilerinden birisi uygulanacak olan risk analizleridir. Risk analizleriyle mevcut tehlikeler bu tehlikelerin neden olabileceği potansiyel riskler belirlenerek iş kazalarının yaşanmaması ya da minimize edilmesi için gerekli önlemler alınmakt...

The siting of Municipal Solid Waste (MSW) landfills is a complex decision process. Existing methods utilize expert scores to determine criteria weights, however, they ignore the uncertainty data and criterion weights efficacy results. In this study, coupled fuzzy Multi-Criteria Decision-Making (MCDM) approach was employed site in Lanzhou, semi-arid valley basin city China, enhance spatial decis...

Abstract Background Despite their important role in railway operations, switches and crossings (S&C) have changed little since conception over a century ago. It stands now that the existing designs for S&C are reaching maximum point of incremental performance improvement, only radical redesign can overcome constraints current imposing on network capacity. This paper describes process pr...
