An Inertial Triple-Projection Algorithm For Solving The Split Feasibility Problems, Yazheng Dang, Marcus Ang, Jie Sun Mar 2023

An Inertial Triple-Projection Algorithm For Solving The Split Feasibility Problems, Yazheng Dang, Marcus Ang, Jie Sun

Research Collection Lee Kong Chian School Of Business

This paper proposes a new inertial triple-projection algorithm for solving the split feasibility problem (SFP).The process of projections is divided into three parts. Each part adopts a different variable stepsize to obtain its projection point, which is different from the existing extragradient methods. Flexible rules are employed for selecting the stepsizes and the inertial technique is used for improving the convergence. Convergence results are proven. Numerical experiments show that the proposed method converges more quickly than the general CQ algorithm.

The New Model For Medicine Distribution By Combining Of Supply Chain And Expert System Using Rule Based Reasoning Method, Mufadhol Mufadhol, Mustafid Mustafid, Ferry Jie, Yuni Noor Hidayah

Research outputs 2022 to 2026

The medicine distribution supply chain is important, especially during the coronavirus disease 2019 (COVID-19) pandemic, because delays in medicine distribution can increase the risk for patients. So far, the distribution of medicines has been carried out exclusively and even some medicines are distributed on a limited basis because they require strict supervision from the Medicine Supervisory Agency in each department. However, the distribution of this medicine has a weakness if at one public health center there is a shortage of certain types of medicines, it cannot ask directly to other public health center, thus allowing the availability of medicines not …


An Exponential Cone Programming Approach For Managing Electric Vehicle Charging, Li Chen, Long He, Yangfang (Helen) Zhou Jan 2023

An Exponential Cone Programming Approach For Managing Electric Vehicle Charging, Li Chen, Long He, Yangfang (Helen) Zhou

Research Collection Lee Kong Chian School Of Business

To support the rapid growth in global electric vehicle adoption, public charging of electric vehicles is crucial. We study the problem of an electric vehicle charging service provider, which faces (1) stochastic arrival of customers with distinctive arrival and departure times, and energy requirements as well as (2) a total electricity cost including demand charges, costs related to the highest per-period electricity used in a finite horizon. We formulate its problem of scheduling vehicle charging to minimize the expected total cost as a stochastic program (SP). As this SP is large-scale, we solve it using exponential cone program (ECP) approximations. …

Alternative Modes Of Entry And Unexpected Events In Franchising, Alexander Rosado-Serrano, Antonio Navarro-García

Journal of Global Business Insights

Store-in-store franchising or corner franchising is the application of a franchise format within another business, such as big box retailers, supermarkets, and gas stations; and pop-up stores are temporary store formats opened in shopping malls or other venues for a short period. Despite the regular application of these strategies by franchisers, the academic literature on store-in-store franchising and pop-up stores is relatively limited. There is a particular need after the COVID-19 outbreak to construct new lenses through which to explore how these modes of entry adapt to the new environment of business interruptions and border closures. Motivated by this research …

Research Collection Lee Kong Chian School Of Business

In this paper, we study an on-demand housekeeping platform in which suppliers have hetero-geneous opportunity costs, and customers are sensitive to service quality, price, and waitingtime. The platform charges fees from customers and divides revenue with service suppliers ina certain proportion. We analyze two types of market coverage, namely full market coverageand partial market coverage. We find that as the potential demand market capacity expands,the platform will choose to lower prices to attract more customers and service suppliers until itreaches the partial market, thereby obtaining higher revenue, and suppliers will provide lowerquality services to serve more customers and thus obtain …

Capturing Sustainability Goals In City Logistics: A Delphi Approach To Develop Sustainability Indicators, Xu Zhang, Eoin Plant, Nikolaos Valantasis Kanellos

Conference Papers

Purpose of this paper: ‘Sustainability’ as a phenomenon is difficult to define and sense (Meadows,1998). Sustainable city logistics is a concept with many subjective interpretations by different actors in the urban freight transport ecosystem (Behrends et al., 2008). Developing useful metrics to measure sustainability performance and impact in city logistics is challenging as there are many uncertainties and multiple stakeholders’ interests to consider. Selecting the indicators is also a complicated task because of the numerous variables used in literature and the variety of KPIs reported by logistics companies in their sustainability reports.

Extant research studies have proposed different frameworks …

Food Insecurity In An Anthropogenic Age: An Analysis Into How Consumer Demand Will Shift During Crisis Events, Chloe G. Parsons, Christina Kuchmaner

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

Consumers in the United States may need to adjust their food demand due to food insecurity caused by climate warming events. Research has focused on how climate change impacts food supply chains and distribution; however, there was little research on how consumers responded to these changes. This study analyzed how consumers across the United States responded to food insecurity caused by crisis events (i.e. pandemics and climate change), how consumers shifted from grocery store vendors to local food vendors, and if migration or food miles may increase based on potential food shortages. One study was initiated through survey and a …


Determinants For The Uptake Of Alternatively Fuelled Hgvs: Towards A Maturity Framework, Nikolaos Valantasis Kanellos, Xu Zhang Jul 2022

Determinants For The Uptake Of Alternatively Fuelled Hgvs: Towards A Maturity Framework, Nikolaos Valantasis Kanellos, Xu Zhang

Conference Papers

Purpose of this paper: Alternatively fuelled vehicles (AFVs) have received increasing attention from policy makers and industry practitioners because they are perceived as a silver bullet for decarbonising freight transport (Mohammed et al., 2020; ITF 2021). However, the uptake rate of AFVs by heavy goods vehicle (HGV) freight operators in Europe remains low. With 97.8% of all trucks in the EU running on diesel, only 0.04% of trucks are zero-emission vehicles (ACEA, 2021). Price, technology maturity, infrastructure, and government policy support are factors examined by freight transport operators who consider the switch to AFVs as a low-carbon option (Mohammed et …
