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...

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 ...

Inland transportation of containers contributes significantly to the total cost container intermodal transportation. For this reason, it has received a lot attention in last few decades. While there are many reports attempts solve problem out there, variants considered all simpler than form addressed paper. Here, we consider where pick-up and delivery orders, empty loaded containers, Discharge ...

Smart cities make use of a variety smart technology to improve societies in better ways. Such intelligent technologies, on the other hand, pose significant concerns terms power usage and emission carbons. The suggested study is focused technological networks for big data-driven systems. With support software-defined transportation-aided multicast routing system suggested. By using public transp...

Research of travel distance on single - depot position in warehouse is tremendous. This study focuses more the effect two-depot order picking problem (OPP) by using concept traveling salesman (TSP) and exact method – Branch Bound (B\&B) algorithm. The total one-depot shorter than for double block warehouses difference less 5%. also compared with approximate methods SA TS which show that dif...

BACKGROUND Noncompliance is a major problem for patients with a psychotic disorder. Two important risk factors for noncompliance that have a severe negative impact on treatment outcomes are impaired illness insight and lack of motivation. Our cross-sectional study explored how they are related to each other and their compliance with depot medication. METHODS Interviews were conducted in 169 o...

Clustering of retail stores in a distribution network with specific geographical limits plays an important and effective role in distribution and transportation costs reduction. In this paper, the relevant data and information for an established automotive spare-parts distribution and after-sales services company (ISACO) for a 3-year period have been analyzed. With respect to the diversity and ...

In contrast to the classical location-allocation models, the location-routing problem (LRP) integrates vehicle routing and scheduling aspects in the location planning process. A survey and classification scheme of location-routing is e.g. proposed by [3] and [2]. This paper presents a LRP of a company which distributes finished cars. This LRP is decomposed into two steps. In the first step a se...
