background & aim: nowadays, home health care services play significant roles in modern societies. such services allow the elderly and needy people to pass their treatment process at their own houses in a friendly environment. in this paper, weekly routing and scheduling problem of home health care personnel was investigated. methods & materials: insufficient number of expert personnel or overla...

in this paper, a stochastic multi-depot multi-objective vehicle routing problem (vrp) is studied. based on observations in real-world problems, we develop an aspect of the problem, such as stochastic availability of routes. to solve the problem in this situation, a two-objective mathematical model is developed, in which the related objective functions are: (1) minimizing transportation costs an...

There is a major resurgence of interest in brown adipose tissue (BAT) biology, particularly regarding its determinants and consequences in newborns and infants. Reliable methods for non-invasive BAT measurement in human infants have yet to be demonstrated. The current study first validates methods for quantitative BAT imaging of rodents post mortem followed by BAT excision and re-imaging of exc...

In this paper, we propose a new routing problem to model a highly relevant planning task in small package shipping. We consider the Prize-Collecting Vehicle Routing Problem with Non-Linear cost (PCVRPNL) in its single and multi-depot version, which integrates the option of outsourcing customers to subcontractors instead of serving them with the private fleet. Thereby, a lower bound on the total...

This paper presents a new mathematical model of the vehicle routing problem in the context of city distribution, which considers multi-depot, multi-model vehicles and multi-task. The objective function includes three parts: transport cost, deadheading cost and time cost. To solve this mathematical model, a self-adaptive and polymorphic ant colony algorithm (APACA) has been introduced. Finally, ...

Some non-specialists raised problems about the turbine pumping system in Al-Faw oil depot, and it reached Office of Internal Oversight some deputies Parliament, so I decided through research to clarify basis on which rely appropriate systems achieve required operational conditions with least energy expended And this reflected choice that were chosen work Al -Faw depot. Through research, was fou...
