This study focuses on identifying the key elements that managers consider when making the decision to upgrade and integrate supply chain management system that are already in use. A survey of information systems managers is used to evaluate the proposed framework and the results of the survey suggests that managers use certain key elements when deciding on upgrading and integrating supply chain...

In recent years, the growth of logistics enterprises is slowing down. On the one hand, it is the result of overall adjustment of the economic structure, on the other hand, it also shows that it is difficult to obtain sustainable development inon the current economic situation for logistics enterprises, all logistics enterprises are faced with a problem that how to transform and upgrade. This ar...

This paper aims at analyzing three different solutions suggested for traffic congestion relief in Port Louis, the busiest city of Mauritius. It evaluates the impact of the three alternatives which are the use of Light Rail Transit LRT as an alternative mode of transport, the construction of a Ring road around Port Louis, and the upgrading of the current bus network into a Bus Rapid Transit BRT ...

Background and purpose: The performance of full-scale moving bed biofilm reactor (MBBR) was evaluated as an alternative for upgrading of Kish Island Mirmohana wastewater treatment plant. In this study activated sludge process upgrade to MBBR process and different operating parameters were compared. Materials and Methods: Effect of upgrading on different parameters such as organic loading rate (...

A qualitative probabilistic network models the probabilistic relationships between its variables by means of signs. Non-monotonic influences have associated an ambiguous sign. These ambiguous signs typically give rise to uninformative results upon inference. We argue that a non-monotonic influence can be associated with a more informative sign that indicates its effect in the current state of t...

We introduce the Upgrading Shortest Paths Problem, a new combinatorial problem for improving network connectivity with a wide range of applications from multicast communication to wildlife habitat conservation. We define the problem in terms of a network with node delays and a set of node upgrade actions, each associated with a cost and an upgraded (reduced) node delay. The goal is to choose a ...

While RHIC has only just started running for its heavy ion physics program, in the first run last summer, we achieved 10% of the design luminosity. In this paper we discuss plans for increasing the luminosity by a factor of 35 beyond the nominal design. A factor of 4 should be straightforward by doubling the number of bunches per ring and squeezing the β* from 2 to 1 m at selected interaction p...

History, goals and problems for Component-based Software Engineering (CBSE) are described. Different available approaches are described and compared to handle change management on CBSE. Based on the approach of “automatically find applied refactorings between two versions of a component” new possible fields of application are given.

This review discusses different strategies for the upgrading of biomass into sustainable monomers and building blocks as scaffolds for the preparation of green polymers and materials.

The increase in the population of the planet and the rapid economic growth and, consequently, the high consumption of energy has created many environmental problems in the globe. Due to these reasons and the lack of renewability of these fossil fuels, there has been a steep trend towards the production of renewable fuels from natural sources, one of which is the production of energy from biomas...
