the study was undertaken with the objectives to: (1) study the present status of plastic waste management and the existing phnom penh household willingness and their influence factors to segregate plastics for recycling and reuse (plastics & non plastics); (2) study how other cities encouraged and obtained the participation of their population in plastics recycling and reuse and (3) recommend w...

background: with the rapid development of health services, the progress of medical science and technology, and the improvement of materials research, the consumption of medical consumables (mcs) in medical activities has increased in recent years. however, owing to the lack of effective management methods and the complexity of mcs, there are several management problems including mc waste, low m...

In a military deployment, the operational availability of deployed equipment will be affected by many factors including equipment usage rates, sparing policy, and importantly the composition and distribution of maintenance personnel. In this paper, we present a Coloured Petri Net model that captures the potentially complex defence logistics maintenance process that links these factors together....

This project focuses on optimizing the location of WEEE collection points for waste electrical and electronic equipment (WEEE) which consists of determining a set of locations to install a network of gathering equipment. It is implemented using open source technologies following the current tendency of the present software market situation. In particular, the software application to be develope...

We describe the use of a questionnaire to define the difficulties in providing anaesthesia in Uganda. The results show that 23% of anaesthetists have the facilities to deliver safe anaesthesia to an adult, 13% to deliver safe anaesthesia to a child and 6% to deliver safe anaesthesia for a Caesarean section. The questionnaire identified shortages of personnel, drugs, equipment and training that ...

E-commerce is a complete process that consists of information flow, capital flow, business flow, and logistics. With the development of network and electronic technology, the information flow, capital flow, and business flow can be momentarily available through computer and network communication equipment. The logistics that must be achieved in reality become a key part in influencing the effic...

The handling of containers in port logistics consists of several activities, such as discharging, loading, gate-in and gate-out, among others. These activities are carried out using various equipment including quay cranes, yard cranes, trucks, and other related machinery. The high inter-dependency among activities and equipment on various factors often puts successive activities off schedule in...

The management of waste electrical and electronic equipment (WEEE) is an important and critical aspect in the field of Reverse Logistics. The strategic importance of good treatment of waste is fundamental for reaching the objectives of environmental protection (as energy, natural resources, waste reduction) and economics goals (the lower cost of secondary raw materials for example). The followi...

Today, the increased public concern about sustainable development and more stringent environmental regulations have become important driving forces for value recovery from end-of-life and end-of use products through reverse logistics. Waste electrical and electronic equipment (WEEE) contains both valuable components that need to be recycled and hazardous substances that have to be properly trea...

TRANSPORTATION AND INFRASTRUCTURE Getting Value from the Reverse Logistics Pipeline For many of the major components on the Army’s weapon systems, trucks, and other major items of equipment, it often makes economic sense to repair them rather than replace them with new ones. Current acquisition and management of these systems in fact plan for and assume that this sort of repair will occur. Thus...
