Significant public procurement changes are forcing road construction companies to professionalise planning and control of asphalt paving projects. In an effort to outperform competitors, companies seek better control over the paving process, over the planning and scheduling of resources and work, and over performance. For the asphalt paving companies to be able to improve product and process pe...

PURPOSE Rear-end crashes attribute to a large portion of total crashes in China, which lead to many casualties and property damage, especially when involving commercial vehicles. This paper aims to investigate the critical factors for occupant injury severity in the specific rear-end crash type involving trucks as the front vehicle (FV). METHODS This paper investigated crashes occurred from 2...

The aim of this paper is to explore the possibility of using rhythm metrics on the traditional units of speech rhythm (the syllable and the foot), instead of applying them to consonantal and vocalic intervals. Despite [14] had already proven that the standard deviation of syllables and feet did not provide a satisfactory representation of the traditional rhythm classes, some recent studies obta...

cross docking is a logistic strategy that plays the role of a middle knot in distribution network in the provision process. in logistic part, inventory holding is considered as an important matter in managing costs. not only cross docking reduces the inventory holding cost, but it also reduces the cost of collecting received orders, transportation and duration of sending. the products, which ar...

For phase transitions in disordered systems, an exact theorem provides a bound on the finite size correlation length exponent: nFS $ 2yd. It is believed that the intrinsic n satisfies the same bound. We argue that the standard averaging introduces a noise and a new diverging length scale. For n # 2yd self-averaging breaks down, disconnecting n from nFS, and the bound applies only for the latter...

Abstract One of the most popular ways shopping in an omnichannel retailing environment is buy‐online‐pickup‐in‐store (BOPS). Retailers often promise BOPS shoppers short in‐store pickup ready times. We study fulfillment scheduling decisions orders destined for a single store retailer. There are two options orders: they can be either processed at center (FC) and delivered to or without needing de...

This paper is concerned with yard management in transshipment hubs, where a consignment strategy is often used to reduce reshuffling and vessel turnaround time. This strategy groups unloaded containers according to their destination vessels. In this strategy, yard template determines the assignment of the spaces (subblocks) in the yard to the vessels. This paper studies how to make a robust yar...

In a supply chain, cross-docking is one of the most innovative systems for ameliorating the operational performance at distribution centers. Cross-docking is a logistics strategy in which freight is unloaded from inbound trucks and (almost) directly loaded into outbound trucks, with little or no storage in between, thus no inventory remains at the distribution center. In this study, we consider...

Carriers are under increasing pressure to offset rising fuel charges with cost cutting or revenue generating schemes. One opportunity for cost reduction lies in asset management. This paper shows how a machine scheduling approach can be used to assign truck loads to delivery times and trucks. We present several models to find optimal assignments when delivery times are flexible. The models have...
