Aiming towards a sustainable supply chain, Physical Internet (PI) has been presented as global logistics network with standardized PI-containers. PI-nodes, and more specifically PI-hubs, are one of the key elements concept. This paper focuses on optimising operations in Road-Road PI-hub, which was not addressed literature. PI-hubs designed to transfer PI-containers between suppliers’ customers’...

The scheduling problem is one of the most important operation in maritime ports. In this study we solved for a single quay crane and multiple yard trucks port Tripoli-Lebanon. previous proposed two exact methods but faced large instances CPU time. For reason, paper developed heuristic method (genetic algorithm) to obtain near optimal solution with an acceptable main objective minimize completio...

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...

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...

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...

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...

The 0/1 knapsack equality polytope is, by deenition, the convex hull of 0/1 solutions of a single linear equation. A special form of this polytope | where the deening linear equation has nonnegative integer coeecients and the number of variables having co-eecient one exceeds the right-hand-side | is considered. Equality constraints of this form arose in a real-world application of integer progr...
