Operational-Level Optimization Of Inbound Intralogistics, Hector J. Carlo, Yeiram Martinez Jan 2016

Operational-Level Optimization Of Inbound Intralogistics, Hector J. Carlo, Yeiram Martinez

14th IMHRC Proceedings (Karlsruhe, Germany – 2016)

This study is concerned with optimizing inbound operations at distribution centers (DCs), warehouses, and cross-docks with staging areas. The objective of the problem is to minimize the makespan required to move all unit loads from the trailers to the flow racks, and from the flow racks to their respective storage locations. It is assumed that a set of inbound trailers with known composition have been assigned and sequenced to inbound dock doors. The following three inbound logistics decisions are simultaneously considered: i) unloaders’ assignment and scheduling, ii) loads-to-flow rack assignment, and iii) assignment and haulers’ scheduling. In this study we …


Understanding Worker Blocking And The Design Process, Russell D. Meller, Lisa M. Thomas Jan 2016

Understanding Worker Blocking And The Design Process, Russell D. Meller, Lisa M. Thomas

14th IMHRC Proceedings (Karlsruhe, Germany – 2016)

Designing a distribution center (DC) is a complex process that consists of answering dozens of interrelated questions. From our perspective, the penultimate question is one of which picking methodology is optimal. To answer this question requires a full evaluation of picking methodologies in terms of their ability to meet the expected throughput requirements of the system. In manual picking systems, as throughput requirements increase, worker interaction and blocking increase as well. This implies that being able to estimate the amount of worker blocking in a system is critical to a design effort. Most of the prior research in this area …

A High-Density, Puzzle-Based System For Rail-Rail Container Transfers, Kevin Gue

14th IMHRC Proceedings (Karlsruhe, Germany – 2016)

We describe a high-density, puzzle-based storage and transfer system for containers in a rail-to-rail hub for the Physical Internet. The system uses a new algorithm called GridHub, which is able to transfer items in all four cardinal directions simultaneously within a grid. We show how the GridHub system might be used in a rail-rail transfer hub to transfer containers between one side of the grid and a train.

Logistics Models To Support Order-Fulfillment From The Sea, Jennifer Pazour, Ian Shin

14th IMHRC Proceedings (Karlsruhe, Germany – 2016)

Sea based logistics use maritime platforms to transfer cargo stored on vessels and delivers them ashore. This chapter describes the motivations and logistical requirements of seabasing. The sea base’s organizational structure, its material handling environment, and the internal cargo flow processes of the T-AKE vessel are described. Three seabasing distribution network scenarios -- Iron Mountain, Skin-to-Skin Replenishment, and Tailored Resupply Packages -- are described and mapped to warehousing and distribution networks, characteristics, and decision problems. Finally, related literature is reviewed and open areas for logistics research to support order fulfillment from the sea are identified.

Integrated Versus Sequential Scheduling And Assignment At A Unit Load Cross-Dock, Arpan Rijal, Marco Bijvank, Rene De Koster Jan 2016

Integrated Versus Sequential Scheduling And Assignment At A Unit Load Cross-Dock, Arpan Rijal, Marco Bijvank, Rene De Koster

14th IMHRC Proceedings (Karlsruhe, Germany – 2016)

Within a cross-dock, the assignment of trucks to dock-doors and the scheduling of trucks to be processed are two major operational decisions. Conventionally, assignment and scheduling decisions are made sequentially. However, solving the two problems sequentially can lead to sub-optimal solutions because the objectives of the two problems are in conflict with each other. To gain further insights, we create an integrated model which is capable of simultaneously scheduling and assigning trucks at cross-docks. We contrast the integrated model with a sequential model which first schedules trucks for processing and then assigns them to dock-doors. Experiments demonstrate that the integrated …

Intermodal Hubs In The Physical Internet, Nadeepa Wickramage, Bill Ferrell

14th IMHRC Proceedings (Karlsruhe, Germany – 2016)

Distribution of finished goods is currently an effective but inefficient process that consumes significant quantities of fossil fuel to move empty assets. This results in increased costs that are passed to the consumer and unnecessarily increased carbon emissions. The Physical Internet (PI) is focused on shared logistics that could prove to be an important element of next-generation logistics systems. The idea is to store and transport goods in anonymous standard-sized containers so that transportation and warehousing can be efficiently shared by many companies including competitors. If implemented, this idea has the potential of dramatically increasing efficiency thereby reducing fuel consumption …

Analyzing Order Throughput Times In A Milkrun Picking System, J. P. Van Der Gaast, M.B. M. De Koster, Ivo J.B.F. Adan

14th IMHRC Proceedings (Karlsruhe, Germany – 2016)

E-commerce fulfillment competition evolves around cheap, speedy, and time-definite delivery. Milkrun order picking systems have proven to be very successful in providing handling speed for a large, but highly variable, number of orders. In this system, an order picker picks orders that arrive in real time during the picking process; by dynamically changing the stops on the picker’s current picking route. The advantage of milkrun picking is that it reduces order picking set-up time and worker travel time compared to conventional batch picking systems. This paper is the first in studying order throughput times of multi-line orders in a milkrun …

Healthcare System-Use Behavior: A Systematic Review Of Its Determinants, Jiming Wu Jan 2016

Healthcare System-Use Behavior: A Systematic Review Of Its Determinants, Jiming Wu

Journal of International Technology and Information Management

To understand patient and physician behavior, researchers have investigated the determinants of using healthcare information systems. Although this stream of research has produced important findings, it has yet to appreciably advance our understanding of system-use behavior in healthcare. To fill this gap, the current paper employs a systematic review to synthesize past research, reveal the key determinants of healthcare system usage, and illuminate a deeper understanding of the topic. This study thus helps healthcare researchers expand their baseline knowledge of these core determinants and conduct more fruitful future research on system-use behavior in healthcare.
