In an era where people in the world are concerned about environmental issues, companies must reduce distribution costs while minimizing pollution generated during process. For today’s multi-depot problem, a mixed-integer programming model is proposed this paper to minimize all incurred entire transportation process, considering impact of time-varying speed, loading, and waiting time on costs. T...

Depot-holders are women from the community who promote good health practice and use of clinics. They keep a stock of contraceptives and oral rehydration salts to supply other women and are paid some incentives. In 2003, the NGO Service Delivery Program (NSDP) introduced depot-holders in three types of urban area in Bangladesh as a pilot. This evaluation study was carried out to: (a) establish a...

this paper discusses the multi-depot vehicle routing problem of heterogeneous fleet of vehicles with time windows for perishable commodities. the objective of the problem is to minimize the total time required for servicing all customers that is equivalent to the total cost. commodities are delivered to the customers with defined time windows by a fleet of heterogeneous vehicles, which have lim...

We consider the vehicle routing problem with stochastic demands (VRPSD) on tree structured networks with a single depot. The problem we are concerned with in this paper is to find a set of tours for the vehicle with minimum expected length. Every tour begins at the depot, visits a subset of customers and returns to the depot without violating the capacity constraint. Randomized approximation al...

This paper studies the multi-depot joint distribution vehicle routing problem considering energy consumption with time-dependent networks (MDJDVRP-TDN). Aiming at where travel time depends on variation characteristics of road network speed in area, influence and relationship between load fuel consumption, a optimization model is established to minimize sum fixed cost, cost window penalty cost. ...

BACKGROUND Depot antipsychotic medication is used widely in the treatment and prophylaxis of severe mental illness. AIMS To review the literature on patient and nurse satisfaction with, and attitudes towards, depots. METHOD A systematic search of Medline, Embase, PsycINFO, CINAHL and The Cochrane Library was undertaken, along with citation searches. Studies were selected if satisfaction/att...

AIMS AND METHOD To establish if participants with schizophrenia receiving depot antipsychotics had less insight than similar participants receiving oral atypical antipsychotics.We assessed the difference between these two groups. RESULTS Participants on oral antipsychotics had greater insight than those on depot antipsychotics (ITAQ, P=0.01). In the multiple regression analysis, only receiving ...
