SAMPLE EXCERPT:

[. . .] The Retail Link of Walmart provides an e-bridge to suppliers, offering information on inventory levels and sales and facilitating purchase order downloads. Such close integration shows suppliers a picture of actual demand, decreasing congestion impacts across the entire supply chain (Stalk & Paranikas, 2015).

Environmental Issues Involving Freight Transport

The environment-transport problem is paradoxical, as the latter, despite its immense socioeconomic advantages, also adversely impacts environmental systems. On the one hand, transport activities increase freight and passenger mobility demands, particularly within urban zones; but on the other hand, they have been linked to increased environmental externality levels. Additionally, environmental conditions influence transport systems (e.g., infrastructural needs like maintenance and construction, and operating conditions) (Rodrigue, 2018).

With transport activities increasing congestion and motorization, the transport sector is being connected, to a growing extent, with environmental problems, the key issues being:

  1. Climate change. The infamous greenhouse effect – a natural process involving partial heat retention within our earth’s atmosphere – form a key element of worldwide climate regulation. Greenhouse gases (which include methane, halocarbons, carbon dioxide and nitrous oxide) accumulate within the atmosphere for a sufficiently long period and attain a homogeneous worldwide composition. Hence, they have a similar concentration everywhere (Rodrigue, 2018).

  3. Air quality. Aircrafts, motor vehicles, trains, and marine engines cause air pollution by emitting particulate matter (dust, ash) and gas (mostly lead, nitrogen oxides, carbon monoxide, benzene, silicon tetraflouride, cadmium, copper, chrome, zinc and other heavy metals), thereby damaging people’s health. Lead emission has dropped to a great extent within the past few decades following the 80s ban of lead as a gasoline anti-knock agent by most nations. The key factors contributing to this ban included tetraethyl lead’s neurotoxic impacts on humans and its catalytic converter impairing property (Rodrigue, 2018).
  4. Noise. Noise pollution involves the general impact of chaos and irregular sounds on both humans and animals. Transport-linked noise (including that attributed to transport vehicles, airport, rail yard, and port operations) also impacts human health, notably by exacerbating cardiovascular disease risks. Ambient noise – the cumulative result of all vehicular noise (between 45 and 65 decibels) – often ensues from road transport within urban areas, and impairs quality of life of urban residents and property values (Rodrigue, 2018).
  5. Water quality. Transportation activities affect water quality and hydrological conditions. Toxic particulates, fuel, and chemicals emitted by automobiles, trains, airplanes, trucks and airport/port terminal operations may lead to hydrographic system contamination (Rodrigue, 2018).

Summary

Numerous conclusions may be arrived at upon an examination of the various effects of congestion businesses and supply chains. Firstly, systems dynamics-based supply chain simulation models clearly prove helpful when explaining why uncertainties and delays linked to congestion result in schedule, location, and delivery lot size shifts. But insights offered by discussions and interviews with companies reveal several other potential aspects of congestion effects and related transformation in business conduct and organization besides commonly cited aspects. In particular, congestion impacts may go well beyond operating expense changes, impacting company, market and manufacturing process nature and size. Moreover, organizations may have diverse responses based on congestion growth nature and kind of business activity impacted (Weisbrod & Fitzroy, 2011).
