Defining and Modeling Risks in Service Supply Chains
(University of Cincinnati, 2021) Karadayi-Usta, S.; Usta, Saliha Karadayı; Serdarasan, S.; Endüstri Mühendisliği Bölümü
Risk management in supply chains is of growing importance and has been studied extensively in manufacturing supply chains. However, risk in service supply chains (SSCs) is largely neglected. Since SSCs are not immune to disruptions, there is a need to study and understand supply chain risks from a service perspective. This paper sets out to identify, define and examine risks in SSCs. Using a systematic literature review, the paper explicitly defines seven risk types associated with SSCs: financial, relationship, demand, operational, service delivery, Information technology (IT), and external risks. To gain a deeper understanding of these risks and their consequences, a structural model of the relationships among them was developed using ISM and MICMAC. This study helps us to identify and understand all the risks that need to be assessed in SSCs, which in turn would lead to enhanced risk management and business sustainability. © 2021 University of Cincinnati.

A New Servicizing Business Model of Transportation: Comparing the New and Existing Alternatives Via Neutrosophic Analytic Hierarchy Process
(University of New Mexico, 2022) Karadayi-Usta, S.
The new normal of the world has been shaped by the COVID-19 outbreak by avoiding public transportation in order to prevent the spread of the disease. Due to the high financial burden of purchasing a car, new business models have been developed in order to make possible of utilizing vehicles to meet the transportation needs in pay-per-use base concept called “servicizing” or “servicization” which is based on presenting a product as a service, and selling the functionality of that product instead of the product itself. In order to meet the increasing demand for individual vehicle use, the existing car rental service providers have provided a new mobile application controlled business model which makes the rental process easier. The aim of this study is to evaluate the customers’ preferences of purchasing, renting through an agency, or mobile application supported new pay-as-you-go business model use, in order to determine which criterion is prominent in the decision-making process, and to identify the weights of these criteria. Due to the uncertain and indeterminate attitudes of the customers in decision making, the data were collected as neutrosophic data sets and analyzed with a novel neutrosophic Analytic Hierarchy Process (nAHP) approach. The study provides implications both theoretically and practically in terms of revealing new servicization possibilities and analyzing real user judgments © 2022, Neutrosophic Sets and Systems.All Rights Reserved.
