Interactive Multiobjective Optimization in Lot Sizing with Safety Stock and Safety Lead Time

2021

In this paper, we integrate a lot sizing problem with the problem of determining optimal values of safety stock and safety lead time. We propose a probability of product availability formula to assess the quality of safety lead time and a multiobjective optimization model as an integrated lot sizing problem. In the proposed model, we optimize six objectives simultaneously: minimizing purchasing cost, ordering cost, holding cost and, at the same time, maximizing cycle service level, probability of product availability and inventory turnover. To present the applicability of the proposed model, we consider a real case study with data from a manufacturing company and apply the interactive NAUTI…

Application of a Knowledge Discovery Process to Study Instances of Capacitated Vehicle Routing Problems

2020

Vehicle Routing Problems (VRP) are computationally challenging, constrained optimization problems, which have central role in logistics management. Usually different solvers are being developed and applied for different kind of problems. However, if descriptive and general features could be extracted to describe such problems and their solution attempts, then one could apply data mining and machine learning methods in order to discover general knowledge on such problems. The aim then would be to improve understanding of the most important characteristics of VRPs from both efficient solution and utilization points of view. The purpose of this article is to address these challenges by proposi…

Basic Elements of Cyber Security for a Smart Terminal Process

2023

Global maritime transportation and logistics systems are essential parts of critical infrastructures in every society, and a crucial part of maritime logistics processes are seaports. Digitalization helps improve the efficiency of terminal systems in the processes of these ports. In Finland this development is going on and it is called SMARTER research program. In the best cases, digitalization can also promote the reduction of emissions by optimizing port operations and enhancing cargo and people flows while improving the experience for all stakeholders. The improvement of port processes relies on the development of Information and Communication Technology (ICT) and as well as on Industria…

CM3 – TRANSPORT 2023 : New Greener and Digital Modern Transport – its Challenges in Design Methods, Tools and Technologies : Book of Abstracts and Pr…

2023

The CM3 – Transport Conference 2023 is organized by the University of Jyväskylä, supported by Jamk – University of Applied Sciences, in Jyväskylä/ Finland. The event represents an ECCOMAS Thematic Conference in the context of the activities proposed by the Industrial Interest Group (IIG) of ECCOMAS. Green and efficient European transport represents an important factor of economic growth to be considered in view of environmental and societal challenges. It is essential to develop the scientific and technological mechanisms to encourage cooperation and competitiveness between transport systems in Europe and in the World. It is also crucial to answer the questions how to conduct and apply rese…

Assessment of Cyber Security risks : A Smart Terminal Process

2023

In Finland, the connections to global maritime transportation logistics systems are an essential part of the national critical infrastructure. As a part of maritime logistics systems, the port's operations are important elements for global maritime traffic and the transportation supply chain. Digitalization of seaport services makes it possible to increase the efficiency of terminal systems in the logistic processes. At the same time, port logistic processes can notably reduce its CO2 emissions by optimizing port operations. The improvement of port processes relies very much on the development of Information and Communication Technology (ICT) and Industrial Control Systems (ICS) or Operatio…

Effects of new logistics services on restaurants' business model and strategy

2016

The restaurant industry is present in every part of the world and has been a subject of significant interest for academic scholars. Despite being a more stable industry, technological innovations have started to reach restaurants as well. The purpose of this research is to study and analyze one of these innovations introduced to the full-service restaurant industry. Traditional delivery services in the restaurant industry have been acting as agents between restaurants and customers with the restaurants being in charge of the delivery. However, the food logistics service providers examined in this study offer their restaurant partners‟ new services such as control of the delivery process and…
