In the current geopolitical and economic conditions, issue of making operational management decisions for effective functioning country's enterprises is particularly acute, taking into account organizational technological features, as well increasing levels risk uncertainty associated, among other things, with need to process flows specific rapidly changing information. this regard, intelligent...

Nowadays, in highly competitive global markets and constant pressure to reduce total costs, enterprises consider group technology and Supply Chain Management (SCM) accordingly and usually separately as the key elements for intra and inter facilities improvement. Simultaneous consideration of the elements of these two disciplines in an integrated design can result in higher efficiency and ...

In this paper we develop a simulation model to evaluate a real-time Emergency Medical Service (EMS) vehicle response system that uses real-time travel time information and assists the emergency vehicle dispatchers in assigning response vehicles and guiding those vehicles through non-congested routes. Different response strategies are evaluated using this simulation model. These include the Firs...

With wavelength division multiplexing (WDM) several optical signals can be transferred in a single optical ber [6][7]. This technology allows more e cient use of the huge capacity of an optical ber but also poses new network design and management problems, especially when wavelength conversion is not possible in the nodes. In this paper we consider the routing and wavelength assignment problem ...

The dairy transportation problem (DTP) consists of determining the best routes to be performed for collecting milk from farms and delivering it to processing plants. We study the particular case of the province of Quebec, where the Fédération des producteurs de lait du Québec is responsible for negotiating the transportation costs on behalf of producers. Several issues are highlighted in the ac...

In this paper, a robust optimization approach is proposed to design a dynamic cellular manufacturing system (DCMS) under uncertainty of processing time of products. In addition, a mathematical model considering cell formation, inter-cell design and production planning under a dynamic environment (i.e., product mix and demand are changed in each period) is presented. Therefore, reconfiguration b...

The thermal treatment of limestone (mainly CaCO3) to produce lime (CaO) is a major contributor CO2 emissions and the literature on decarbonising industry scarce. Subsequent hydration would lead synthesis slaked/hydrated Ca(OH)2; production tonne Ca(OH)2 emits ?1.2 tonnes arising mainly from process chemistry fossil fuel combustion. Carbon Capture & Storage (CCS) technologies are currently belie...

This paper explores some of the traffic phenomena that arise when drivers have to navigate a network in which queues back up past diverge intersections. If a diverge provides two alternative routes to the same destination and the shorter route has a bottleneck that generates a queue, one would expect that queue to stabilize at an equilibrium level where the travel time on both routes is roughly...

Background & Aims of the Study:  Collection and transportation of municipal solid waste (MSW) for various reasons, especially economic and social are considered as one of the most important elements of the solid waste management system. More than sixty percent of the costs in solid waste management systems in different countries are due to the collection and transportation...
