R&D Consortia In Competitive Supply Chains, Pascale Crama, Gaoyan Lu, Yi Xu

Research Collection Lee Kong Chian School Of Business

R&D consortia, which coordinate R&D activities of their member firms, have been successful in many industries. We study a model with two competing supply chains each consisting of a manufacturer and a supplier. The manufacturers compete in the final product market, and can conduct R&D to reduce unit product costs of their final products. The R&D can be done in three different ways: by the two manufacturers independently, by them jointly in a horizontal R&D consortium, or by the supplier and the manufacturer jointly in each supply chain in two vertical R&D consortia. We find that as compared to independent …

Coordinated Delivery To Shopping Malls With Limited Docking Capacity, Ruidian Song, Hoong Chuin Lau, Xue Luo, Lei Zhao

Research Collection School Of Computing and Information Systems

Shopping malls are densely located in major cities such as Singapore and Hong Kong. Tenants in these shopping malls generate a large number of freight orders to their contracted logistics service providers, who independently plan their own delivery schedules. These uncoordinated deliveries and limited docking capacity jointly cause congestion at the shopping malls. A delivery coordination platform centrally plans the vehicle routes for the logistics service providers and simultaneously schedules the dock time slots at the shopping malls for the delivery orders. Vehicle routing and dock scheduling decisions need to be made jointly against the backdrop of travel time and …

Such testing arises in the context of the manufacture of products that must perform reliably in extreme environmental conditions. Often, these products must receive a certification from prescribed regulatory agencies at the successful completion of a predetermined series of tests. Operational efficiency is enhanced by determining the optimal order and start times of tests so as to minimize the makespan while ensuring that technicians are available when needed to complete in-process and at-completion inspections. We refer to this as the product test scheduling problem. …

Invited Perspective - Nutritional Needs And Implications For Children In Subsistence Marketplaces, Nagendra Rangavajla

Subsistence Marketplaces

Today, while the number of stunted children is decreasing in all geographies, the progress is not consistent. Moreover, there is an increasing prevalence of overweight and obesity among children and adolescent. Globally, about half of all children under five do not receive essential nutrients, often unnoticed until too late. On the other end of the spectrum, the incidence of overweight and obesity in 5-19 year old has increased from 4% in 1975 to 18% in 2016 ¹. These trends reflect a ‘triple burden of malnutrition’, a burden that impacts the survival, growth, and development of children, and in turn, …

How Incidents Impact Congestion On Roadways: A Queuing Network Approach, Pedro Cesar Lopes Gerum, Melike Baykal-Gursoy

Supply Chain Management

Motivated by the need for transportation infrastructure and incident management planning, we study traffic density under non-recurrent congestion. This paper provides an analytical solution approximating the stationary distribution of traffic density in roadways where deterioration of service occurs unpredictably. The proposed solution generalizes a queuing model discussed in the literature to long segments that are not space-homogeneous. We compare single and tandem queuing approaches to segments of different lengths and verify whether each model is appropriate. A single-queue approach works sufficiently well in segments with similar traffic behavior across space. In contrast, a tandem-queue approach more appropriately describes the density …

On The Feasibility Of Speed Limits In Ocean Container Shipping, Manwo Ng

Information Technology & Decision Sciences Faculty Publications

The maritime industry is witnessing an increasingly loud call to contribute to the global trend towards environmental sustainability and decarbonization. One possible policy measure is the use of speed limits to reduce harmful emissions from ocean shipping. While the idea of slowing down ships to obey speed limits might seem intuitive, one key distinguishing characteristic of container shipping is that it is designed to adhere to a fixed, typically weekly, sailing schedule. This paper contributes to the literature investigating the feasibility of speed limits by demonstrating that speed limits are not always feasible in container shipping because of the rigid …

Exploring Blockchain Adoption Supply Chains: Opportunities And Challenges, Adrian V. Gheorghe, Omer F. Keskin, Farinaz Sabz Ali Pour

Engineering Management & Systems Engineering Faculty Publications

In modern supply chains, acquisition often occurs with the involvement of a network of organizations. The resilience, efficiency, and effectiveness of supply networks are crucial for the viability of acquisition. Disruptions in the supply chain require adequate communication infrastructure to ensure resilience. However, supply networks do not have a shared information technology infrastructure that ensures effective communication. Therefore decision-makers seek new methodologies for supply chain management resilience. Blockchain technology offers new decentralization and service delegation methods that can transform supply chains and result in a more flexible, efficient, and effective supply chain. This report presents a framework for the application …

Containing Compounding Container Congestion, Curtis Salinger

CMC Senior Theses

The Covid-19 pandemic caused major disruptions throughout the container shipping supply chain. Professor Dongping Song of Liverpool University wrote a paper discussing the logistical vulnerabilities in the supply chain, including the issue of congestion in ports. This paper examines the Port of Los Angeles from 2018-2021 as it relates to Song’s paper to see how its operations were impacted during the Covid-19 timeframe. It is found that labor shortages, chassis shortages, and change in trade behavior each contributed to the congestion. Unfortunately, the implemented policies were insufficient to bolster the port against sustained challenges and congestion continues to worsen.
