The fuzzy particle swarm optimization (FPSO-RRB- algorithm is used to solve the logistics transportation time problem, a three-dimensional coding method based on receiving point, position sequence and rounding operation proposed, results are compared with those of algorithm. experimental show that can effectively optimize time.

PROBLEM/CONDITION Physical activity is a health-enhancing behavior, and most U.S. adults do not meet the 2008 Physical Activity Guidelines for Americans. Active transportation, such as by walking or bicycling, is one way that persons can be physically active. No comprehensive, multiyear assessments of active transportation surveillance in the United States have been conducted. PERIOD COVERED ...

Given facilities with capacities and clients with penalties and demands, the transportation problem with market choice consists in finding the minimum-cost way to partition the clients into unserved clients, paying the penalties, and into served clients, paying the transportation cost to serve them. We give polynomial-time reductions from this problem and variants to the (un)capacitated facilit...

While there exist a plethora of classification algorithms for most data types, there is an increasing acceptance that the unique properties of time series mean that the combination of nearest neighbor classifiers and Dynamic Time Warping (DTW) is very competitive across a host of domains, from medicine to astronomy to environmental sensors. While there has been significant progress in improving...

this paper examines the effect of the poor road transportation network on crop production in one of the rural agrarian local government of kwara state, nigeria. a well-structured interview schedule was conducted to elicit information from 120 crop farmers using a two-stage sampling technique. findings from the study revealed that the poor road transportation network in their area had led to a r...

road transportation by way of automobiles is a very convenient means of transportation. today, the most detrimental consequence of developing transportation systems in a country is traffic accident that places a huge financial burden on society. this paper investigates the role of information systems in transportation safety that leads to improved planning and operation of the transportation sy...

BACKGROUND Descriptive data on active transportation in children focuses on the trip to school and has relied on subjective reports. The purpose of this study was to use objective measures to describe total active transportation and active transportation to common destinations within children. METHODS This was a descriptive study of 388 children aged 10-13 years from Kingston, Ontario, Canada...
