Entry-Item-Quantity-ABC Analysis-Based Multitype Cigarette Fast Sorting System

2012

Published version of an article in the journal: Mathematical Problems in Engineering. Also available from the publisher at: http://dx.doi.org/10.1155/2012/847591 Open access Numerous items, small order, and frequent delivery are the characteristics of many distribution centers. Such characteristics generally increase the operating costs of the distribution center. To remedy this problem, this study employs the Entry-Item-Quantity (EIQ) method to identify the characteristic of the cigarette distribution center and further analyzes the importance degree of customers and the frequently ordered products by means of EQ/EN/IQ-B/IK statistic charts. Based on these analyses as well as the total rep…

Some awkward issues on pairwise comparison matrices

2017

Many decision-making techniques use pairwise comparisons (PCs) elicited by one or more stakeholders involved in a given corresponding decision-making process. In very complex problems, the number of criteria or options to be compared may be too large, thus limiting PC applicability to large-scale decision problems due to the so-called curse of dimensionality, that is, a large number of pairwise comparisons need to be produced from a decision maker. For example, in AHP, Saaty [1] recommends that to obtain a reasonable and consistent PC matrix, the number of comparing elements should be at most seven. In [2] and [3], arguing on limitations of the human capabilities, the maximum number of elem…

Calibration of microscopic traffic simulation models for evaluating operation and safety performance at roundabouts

Shared Leadership Regulates Operational Team Performance in the Presence of Extreme Decisional Consensus/Conflict: Evidences from Business Process Re…

2019

This study focuses on decision-making within operational teams. Grounding our argumentation on group decision-making literature, we argue that adverse behavior patterns may affect the way in which consensus is achieved within the team, and that team performance has an inverted U-shaped relationship with the level of consensus. Then, by relying on leadership literature, we pose the hypothesis that the level of shared leadership inside the group moderates this U-shaped relationship. To empirically test our literature-based argumentation, we use longitudinal data collected in the years 2014 and 2015 from business process reengineering projects, each lasting three months, conducted by 141 maste…

A heuristic algorithm for project scheduling with splitting allowed

1996

In this article, we analyze the precedence diagramming method, the only published algorithm for time-only project scheduling with activity splitting allowed. The criteria used in this method (forward and backward pass computations) for deciding when an activity has to be interrupted are shown to be invalid in some situations. We look into the causes of these failures and propose new formulae that always provide feasible solutions. The new algorithm has been tested on 240 randomly generated problems ranging up to 600 activities and 7,200 precedence relationships, resulting in an average deviation from optima of less than 1 percent.

Developmental Psychologists’ Perspective on Pathways Through School and Beyond

2014

This chapter applies sequence analysis—a method rarely applied by psychologists—to examine the transitional pathways of young people through the Finnish education system from a developmental psychologists’ perspective. Our aims were threefold: First, to identify typical pathways; second, to investigate whether psychological resources, operationalized as career goal appraisal, predict a certain educational trajectory; and, third, to examine the extent to which career goal appraisal shows differential change among young people on different educational pathways. Data analyses were based on the FinEdu study, in which N = 611 Finnish students were followed from age 16 (end of comprehensive schoo…

Liquid−Liquid Equilibria for the System 1-Methyl Propyl Ethanoate (1) + Acetic Acid (2) + Water (3) at (283.15 and 323.15) K

2009

Liquid−liquid equilibrium (LLE) data for the system 1-methyl propyl ethanoate + acetic acid + water were measured at temperatures of (283.15 and 323.15) K. The temperature influence on the LLE data is very small in the temperature range studied. The NRTL and UNIQUAC models were used to correlate the data for both ternary systems. The interaction parameters obtained from both models successfully correlated the equilibrium compositions.

THE REFERENCE SITE COLLABORATIVE NETWORK OF THE EUROPEAN INNOVATION PARTNERSHIP ON ACTIVE AND HEALTHY AGEING

2019

International audience; Seventy four Reference Sites of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) have been recognised by the European Commission in 2016 for their commitment to excellence in investing and scaling up innovative solutions for active and healthy ageing. The Reference Site Collaborative Network (RSCN) brings together the EIP on AHA Reference Sites awarded by the European Commission, and Candidate Reference Sites into a single forum. The overarching goals are to promote cooperation, share and transfer good practice and solutions in the development and scaling up of health and care strategies, policies and service delivery models, while at the…
