This study analyzes an inventory control problem of a company in stochastic demand environment under carbon emissions regulations. In particular, a continuous review inventory model with multiple suppliers is investigated under carbon taxing and carbon trading regulations. We analyze and compare the optimal (Q,R) policies with order splitting under two ordering policies: sequential ordering and...

Highlights: A manufacturing supply chain dealing with decaying inventory is studied three production sub-cycles. Price-based demand, the Weibull degradation rate and carbon tax policy are taken into account. Price, emission factor, cycle length period decision variables to increase profit. Goal: The research work aims maximize profit for a deteriorating inventories. To profit, optimum value of ...

A driving cycle is the fundamental concept in conducting emission testing and modeling. The quality of a driving cycle is directly associated with the accuracy of any air quality analysis, and therefore whether the emission reductions can be achieved. However, the widely used driving cycles bring considerable uncertainties when the emission estimation is carried out for a specific city or regio...

With the development of offshore and Pelagic Fisheries, continuous expansion fishing routes, corresponding ship tonnages are increasing, air pollution vessels is becoming more serious. An fishery research vessel was selected as object, emission factors were obtained according to its basic data, method based on fuel consumption adopted calculate pollutants (NO x , HC, CO PM 10 ) inventory establ...

As formaldehyde (HCHO) is a high-yield product in the oxidation of most volatile organic compounds (VOCs) emitted by fires, vegetation, and anthropogenic activities, satellite observations of HCHO are well-suited to inform us on the spatial and temporal variability of the underlying VOC sources. The long record of space-based HCHO column observations from the Ozone Monitoring Instrument (OMI) i...

[1] We present a methodology for deriving emissions of volatile organic compounds (VOC) using space-based column observations of formaldehyde (HCHO) and apply it to data from the Global Ozone Monitoring Experiment (GOME) satellite instrument over North America during July 1996. The HCHO column is related to local VOC emissions, with a spatial smearing that increases with the VOC lifetime. Isopr...

Realizing the transformation from “dual control of energy consumption” to carbon emissions” is inherent requirement realizing carbon” goal. Scientific planning provincial decomposition method total emissions an important content top-level design management, and support for implementation control. Based on application research greenhouse gas inventory in all fields, this paper conducts a full fa...
