Globalization, disruption and unpredictable disaster are now playing notable roles which every business in all sectors need to be emerged a resilient supply chain. In this dynamic context, which risks and disruptions on supply chain are now raised, a resilient supply chain have been addressing to tackle problems simultaneously at the right ways and in a manner of time. A resilient supply chain is currently increasing attention from both academic and practitioners but resilient supply chain has attracted less attention in the service industry perspective. Due to the complex structure and unique characteristics of service industry, there is dearth on the extant literature review especially in service industry rather than manufacturing organizations. Therefore, this research is an exploratory study which aims to explore the importance of supply chain resilience and develop a resilient supply chain paradigm for service industry within Thailand context. The variety of Thai service businesses are selected as the sampling in this research. The raw data was conducted with key informants in Thai service industry. Thematic analysis was implemented as a data analysis method. Hence, the exploration from this research identifies the importance of a supply chain resilience paradigm in Thai service industry context to leverage organization performance, sales and customer satisfaction from organization disruptions. The research contribution aims to raise awareness and outlines the resilient supply chain paradigm as a guideline to Thai practitioners in service industry.

Over the past two decades, the hub & spoke system has significantly changed the behavior of strategic investment decisions in the port sector. Transshipment has significantly changed the composition and throughput traffic for the maritime industry, as a result, capacity has largely increased. This work aims to measure and compare the terminal economic performance based on two criteria: technical efficiency and scale efficiency for 33 container terminals in the Mediterranean basin. We have opted for the DEA (Data Envelopment Analysis) method for the measurement of the economic performance and we have used cross-sectional data for the benchmark in one point of time. DEA doesn't require any specification of the functional form. DEA as a non-parametric programming approach helps in determining the efficiency of a DMU (Decision Making Unit). The findings of this work show that 58% represents the Constant Return to Scale Technical efficiency, this result is broken down into 69% for pure technical efficiency and 83% for scale efficiency, therefore, the findings show that terminals are suffering from a shortfall in terms of overall technical efficiency. Most terminals are operating on decreasing scales. Strategic decisions in terms of investment are of major interest to the management of the container terminals sector.

The increase in the use of IT for process management support has required organizations to make greater efforts to monitor the performance of their technological services to ensure that they provide timely and relevant information. In this context, the purpose of the research is to present a model to monitor the status of IT services that identifies incidents and mitigates their impact through preventive actions. The model has been built by applying process design, incident management, and process indicator monitoring concepts. Its structure is based on five components that offer the actions necessary for incident identification and monitoring, with implementation and operation processes being the transversal component. The model was validated by identifying and monitoring three incidents of the SAP ERP service, whose performances were measured in a time interval. The results show that the monitoring model allows for efficient monitoring of IT service statuses and for the execution preventive actions.

This paper addresses the Capacitated Vehicle Routing Problem (CVRP) consisting of a single depot and several customers that are supplied with goods by capacitated vehicles from a depot. The main objective of the vehicle routing problem is to minimize the traveled distance of all vehicles. We compare the Tabu Search (TS) and Simulated Annealing (SA) algorithm with different initial solution strategies to solve the CVRP. We run the publicly available solver on a set of benchmark problems comparing above mentioned methods and initial solutions. The results show that TS appears superior for small-sized problems, while SA has an advantage for mid-sized problems. For larger problems the preferability of a methods depends on the available run time with SA appear promising for shorter runtime and TS for longer.
