quality and safety. Extended shelf life refrigerated foods are foods that have received minimal processing or precooking and have an enhanced but limited shelf life; refrigeration is a key preservation measure. These foods include conventional products, such as luncheon meats and cured meats, as well as a new generation of partially processed refrigerated foods (NFPA, 1988) such as meat, seafoo...

The inefficiencies arising from increased freight road traffic in the late 1990s in Mexico have posed to planners engaged in the road provision the goal to find new control measures to reduce the adverse impacts, such as road damage and overloading. In the 1990s, road freight traffic in Mexico altered notably after the deregulation of the road freight industry in 1989; the North American Free T...

The aim of this paper is to apply a new categorisation algorithm to an existing database of case studies in order to investigate its effectiveness in sorting unknown train vibration signals into freight and passenger train categories for exposure-response analysis. Relatively little work has been performed on the human response to vibration from railway transportation when compared with respons...

Freight movement is a dynamic process involving with complex interaction among many agents by which the commodities are flowed through supply chains. Simulation based model allows such dynamic and complex interaction system to be undertaken. Simulation based multi-agent approach is therefore utilized to model the behaviors of agents and their interactions in supply chains in order that the mech...

The Michigan Department of Transportation (MDOT) is an intermodal agency tasked with the mobility of the state's citizens, businesses and visitors. Freight and public transit are essential components of Michigan's transportation system. To further MDOT's goal of leveraging technology to maximize safety, mobility, environmental performance, and asset management through mode-specific research pro...

Butter is often stored for extended periods of time; therefore, it is important for manufacturers to know the refrigerated and frozen shelf life. The objectives of this study were to characterize the effect of refrigerated and frozen storage on the sensory and physical characteristics of butter. Fresh butter was obtained on 2 occasions from 2 facilities in 113-g sticks and 4-kg bulk blocks (2 f...

in this paper, we develop a freight transportation model for railway network considering hazmat transportation issue. in the transportation system considered, different customers can request for carrying hazmat and non- hazmat boxes. it is assumed that the sequence of the trains in the network is known. the objective is assigning the non-hazmat boxes and hazmat boxes to wagons of the trains so ...

Investigations were carried out on development quality evaluation and shelf life studies of buffalo meat emulsion sausage prepared by different levels of fat and skimmed milk powder (SMP) at refrigerated storage temperature (0°C). The quality of emulsion sausage was based on the basis of physico-chemical characteristics namely moisture content, pH, protein content, TBA number, microbial charact...

The rail freight carload service segment enables the distribution of freight volumes down to the unit of single rail cars, and stand as an important alternative to road transportation. However, this service segment is often associated with significant uncertainties and variations in daily freight volumes. Such uncertainties are challenging to manage since operating plans generally are establish...

Rail-guided vehicles (RGVs) are widely employed in automated freight handling system (AFHS) to transport surging air cargo. Energy-efficient routing of such vehicles is of great interest for both financial and environmental sustainability. Given a multi-capacity RGV working on a linear track in AFHS, we consider its optimal routing under two-sided loading/unloading (TSLU) operations, in which e...
